um, good morning um, everyone. Um first

of all I would like to thank um the

honorable um director of um University

of Muhammad Sidario for uh inviting me

to this um event as well as um the

faculty members, staffs and the

committee who um very kind to invite me

to this event. Um today my plan is to

um

share uh what I have um started um about

16 years ago um related to the topic of

this um or the theme of this conference

uh speaking of you know innovation and

technology or infrastructure to support

sustainable

um development. uh it just happened to

be um um along the line with um my own

research that I started in 2010. Um I'm

going to um share my screen.

Let's see.

Okay.

Thank you also to uh Miss Doriel Aziza

for the very nice introduction. Really

appreciate um

the brief introduction to my background.

Okay, hopefully you can all see my

my PowerPoint.

Can somebody confirm?

Yes.

Can you see my presentation?

>> It's in.

>> Okay. Thank you. And so my

>> my um title of the presentation today is

um hybrid ACDC house for future net zero

energy homes uh progress opportunities

and challenges. Um again this is um uh

research that I started um back in 2010.

uh in terms of the um outline of the

presentation. I'm going to start off

with um some brief history about the

research and then I'm going to move on

to future sustainable net zero energy

homes, reasons why I believe we need to

complement um AC with DC and then I'll

go over a little bit about um the

proposed solutions, challenges,

opportunities and then I'm going to

close it off with a summary

of

a bit just um a little bit of a history

behind what I've done. Back in 2010, uh

I started this project called the DC

house project. And the main idea there

is to be able to leverage uh renewable

energy sources, energy storage as well

as the increasing prevalent of DC loads

into off-grid house. So that was

strictly uh for off-grid uh meaning the

application would be mainly for rural uh

rural electrification

or remote areas right electrification in

remote areas secluded islands and such

uh things like that. Um and since then

I've delivered um quite a number of

keynote speeches to share what I've

done. um 2015 we we we built a um DC

house prototype in the Philippines and

then followed in 2016 at um

Jaran for another prototype and then um

as I'm as I was doing the um

presentations about DC house there's

always one common question that that was

being raised Um and that was the

question on how can we adopt this

technology in urban areas and so while

uh the main or the initial reason was to

help rural applications however uh the

project evolves into um ways for

facilitating um future um future homes

in urban areas as well. And so uh since

now we are considering um urban areas or

homes in urban areas. Therefore we

cannot forget the fact that in many

cities these are all already connected

to the power grid. Because of that um we

have to somehow uh incorporate uh AC

back into the electrical systems. Hence

the name now is hybrid ACDC house. So

that started off in in 2017

and we do have a prototype at Calpali

and still in progress in terms of uh

work and these are just some pictures um

to show you the uh prototypes of the DC

house uh the beginning of the project uh

one at Koli, one in Bajaran University,

one in the Philippines and one in some

government office in Jatinor.

Um okay. So when it comes to

infrastructure to support um sustainable

energy um especially for future um um

support of um renewable energy uh in the

US um if you uh look it up uh Department

of Energy uh which is a federal agency

in in the US has already launched um the

the vision for for having you know

future homes which they call uh zero

energy ready home. So ze is the official

name and um by that by their definition

uh z is a high performance home that is

so energy efficient that renewable

energy system could offset most or all

the homes annual energy use. So uh a few

key properties of this um zer would be

that it is AC grid type uh produces as

much renewable energy as they consume

over a year uh combines advanced design

and superior building systems. However

um it would mostly rely on DC operated

solar panels as you can see from this

picture right here as the energy source

and optional energy storage which is

also DC operated. uh in addition to that

um because this is a future home so

therefore it's going to be a smart house

as well and if it's a smart house that

means it will have to incorporate um

sensors intelligent devices ICT

technologies and so on so forth which

are also operated by DC or DC

electricity and so uh coming from that

uh background if we are to stick with

the conventional AC or traditional AC

house, then it will be difficult for us

to be able to achieve the net zero

energy homes or the zero energy ready

homes, right? Because um of the fact

that we have uh DC sources and

increasing DC load. So, it is going to

be more challenging if we are just going

to be content with what we have now. So,

we're going to have to uh step up, you

know, um in terms of um the electrical

system that we need to u improve in the

house. And so, particularly I'm

interested in introducing DC into our

electrical system in the house.

and um problems with AC is that um the

reason why I believe it's going to be

more challenging to achieve net zero

energy homes because we have this

problem with AC

um basically I would say the main

problem is the mismatching between the

sources and the loads right our loads um

nowadays we have more and more DC loads

compared to let's say 10 years ago right

and the problem with um having DC loads

powered by AC by AC is that in the

process you're going to have to you're

going to have to uh convert from AC to

DC right and by doing so we're going to

have um this amount of losses right when

you convert from AC to DC the amount of

power loss going to be between 17 to

35%. Right? So that's that's um not good

in terms of trying to save uh power

meaning trying to achieve the net zero

energy homes because that's going to be

make making it difficult.

Um another uh if if you look at this

example we have increasing DC loads um

such as a smartphone right that is being

charged to the wall. If you just look at

one cell phone, maybe that's that

doesn't matter that much. But if you

look at the entire world for example,

right, the bigger scale, we have about

two billion cell phones or smartphones

back into 2021. Um, uh, I'm I'm

convinced that, you know, by now, 5C's

later, we should we have even more than

two billion cell phones, right? Or

smartphones. And if you just do a very

quick uh calculation of power, right? U

so let's say it's being charged by USB

which is 5 volts. And let's say let's

say that um um on the conservative side

it going it's going to draw one amp and

you're going to charge it for one hour.

If you multiply these numbers by the two

billion smartphones that we have in the

world, then that's going to give us a

very large um energy, right? uh 10

gawatt hours of energy. So now we're

talking about a lot of zeros, not just a

small single phone, right? And so

imagine this big energy if it's being

processed through AC, then you you can

just get the you know do the math,

right? 17 time 35% 17 to 35% loss um

times you know power loss or power being

used by the smartphone is going to give

you a big um humongous you know power

loss. Uh same thing with LED lights. I'm

not going to go to um to uh discuss that

one but nowadays our lightings are made

of DC right LED lights are all DC. So

when you have LED light bulb then within

each light bulb you're going to have to

convert from AC to DC. So that's you

know more loss going on in your house.

And another reason why I believe we

should complement AC with DC is because

of um the advance in technologies

facilitating facilitating the increased

proliferation of residential DC loads. A

good example would be USBC, right? More

and more loads nowadays are being

powered by USBC, right? Initially USBC,

one single USBC can power 100 watts. But

now it has been upgraded to 240 watts.

So you can imagine with a single USBC

cable, you can actually power 240 watt

load, which is not small anymore, right?

And so because of that uh it would uh

promote more and more DC loads be to be

used in in our house. And of course on

top of it we have rooftop solar panels

which are basically DC source right at

our fingertips. So if you have a a

source a DC source in your house and you

have DC loads then why go through uh

this you know processes right at the

bottom of this picture the bottom

picture right that's what we're doing

now right you have a DC source from PV

and then you convert it to AC right

because your house is using AC but then

your load is DC so now from AC you go

back to DC and in the process you're

going to lose um so much losses is

right. Um rather than doing that why not

we we go with the top figure right right

here where you have DC source DC loads

then go go ahead and directly convert

from DC to DC by doing so you have uh

less power loss when you have power less

power loss that means you have um then

you help right in terms of achieving the

net zero energy homes

same thing with um energy storage which

is also DC right um nowadays this is

becoming more common. Um so what is the

proposed solution? Um as I as I

mentioned earlier uh since this is going

to be um connected to the grid so it'll

be good to be able to combine right

combine the two uh electrical systems.

So one coming from the AC grid or paral

in in our country right and then the

other one's coming from the rooftop

solar panels or the energy storage. So

you have a dedicated line from AC AC

source or the grid to AC loads. Then you

also have a dedicated line from the DC

source to the DC loads. And in between

the two, you're going to hybrid the two

systems, right? For example, from AC, it

goes to DC or it may go to DC uh loads

or if you uh have DC can also power AC,

right? So just in case for example

during nighttime when there is no solar

energy anymore so therefore the uh the

grid will be powered from uh sorry the

grid will power the DC loads right and

then if let's say we have uh enough

sunlight during the daytime then we can

disconnect the grid and then power the

AC load straight from uh the solar

panels. So uh so these are the

properties of uh our hybrid AC/DC house.

We have dedicated AC line, dedicated DC

line, crisscrossing between the two and

battery is optional.

And um just quickly, in order to um you

uh employ this kind of technology or

hybrid technology, you need to have a DC

combiner. And there are many ways to do

this, but one of the solution that we

propose is called MISO. Uh stands for

multiple input, single output. This is a

a patent that I had um back a few years

ago.

Here's the a picture of the prototype of

a hybrid AC/DC house. Uh this is just

showing you the the electrical system.

It's not really a house, but uh close

enough, right? that what what we are

trying to achieve here is to showcase

um um the ability to hybrid AC and DC

into a single um house structure.

All right. So then um what kind of

challenges do we have um now that we

talk about the proposed solution? First

of all, I would like to emphasize that

challenges present opportunities for new

technological developments which further

bringing in innovations. Right? So I

love challenges because challenges means

uh at the end um opportunities to

innovate. And so these are the list a

list of some of the challenges that I've

encountered when uh doing this uh

research. Uh the first one is the

limited DC sources and maximizing the

use of renewable energy source. Uh this

is even becoming more important in areas

where AC grid is not reliable. And then

the another challenge is uh adopting

other renewable energy sources besides

solar panels for example the wind, hydro

um whatever it is temperature difference

you name it. Um and then another

challenge would be the DC bus and DC

loads are not yet standardized unlike AC

right AC is all standardized but that's

not the case for DC. Uh DC is also more

difficult to protect and to protect from

faults because in AC you have the zero

crossing right which is um a good point

where we can uh separate the contacts in

the circuit breakers. Um but in DC uh

current is always high and then there's

no uh there's there are strict

regulations regarding DC because of the

ability to back feed power to the grid.

And finally um a way to unify

um or not unify but coordinate all of

these uh DC components as well as AC

components into a single house creating

what we call the EMS energy management

system.

Um this is just some ideas for um or

maybe um new ways to um reuse renewable

energy. I won't go through this in

details but you can see um on the left

side you have this humongous wind

turbine which is which looks ugly. And

so in the US we have this term called

nimi. Nimi stands for not in my

backyard. So even though having a wind

energy is good but then who wants to

have this big ugly and noisy wind

turbine in their backyard right so it's

um it's a eyesore right they call it

here so rather than doing that why not

have technology that would hide hide the

wind the wind generator for example here

you can see the slits right the openings

on the rooftop right there and inside

the slits right there there's actually

wind generator like smaller wind

generators that you can put in parallel

or series whatever it is and then wind

wind blows into the roof and it would

turn the the wind turbine the wind

generator right so that way it's more

aesthetic than having the big ugly wind

turbine so I'm sure um students uh will

have more creative ideas on how to uh

quote unquote hide the the wind

generator so that it would not be an

eyesore anymore

I'm going to skip this one. This is just

more ideas. Um due to the time limit um

this is what I meant by um unifying

energy management system. You have

different components critical components

in the hybrid AC/DC house. You have the

the grid, you have the solar panel, you

have the battery, you have inverters,

all all kinds, right? You have the AC

loads, DC loads. So the question is how

do you how how are you able to

coordinate all of these components so

that so that they can talk to each other

and they can be used uh in a um what do

you call in a more coordinated manner

right so that's uh one challenge that

I've I have not done because my

background is not really on on what do

you call it a software side I'm more on

the hardware side so maybe if you're

interested you could uh try to develop

the EMS system for the hybrid AC/DC

house.

Um these are the stuff that I've more

interested in doing which are the

hardware portion of it. As I said

earlier, um there's challenges with DC

loads. One of them is that they're not

standardized. So if the if the input is

only one voltage, let's say 48 volts,

the load could be any voltage, right? It

could be 5 volt, 12 volts, uh 24 volts.

So if that's the case, then are we going

to use multiple wall plugs? I don't

think so. Right? That's going to be um

confusing to use. So therefore, uh we

got this idea of of uh developing what

we call smart wall plug where we have a

DC one DC bus voltage and outputs any

voltage that the load would would

require. So if the load requires five

volts then the wall plug will try to

find it. So that way we have just one

single wall plug we call it smart wall

plug and nowadays we have the technology

that can actually do that called USBCPD.

So if you are interested in developing a

smart wall plug for DC you can go ahead

and look up USBCPD.

Um another thing is the protection right

as I said earlier um

this is harder to protect because of the

higher current right uh continuous

current and so in order to um interrupt

DC energy we use what we call solid

state DC breaker and this is one of the

examples uh of one of my students

projects where he developed the solid

state DC breakers and for those of you

are interested um go ahead and look up

dig Digital electricity. This is the

latest and greatest technology for DC.

Um if you're interested, go ahead and

and uh search for these keywords. Okay,

digital electricity. So this is a new

way of operating DC in our in in future

homes, right? So again, it's called

digital electricity.

And uh in terms of opportunities, we can

use hybrid AC/DC for many obligations

including network of hybrid AC/DC house

uh which will be useful for um rural

electrification. Rather than using

centralized

uh system, we can use distributed system

using hybrid ACDC house to uh improve

reliability.

And um another opportunities would be

everything is DC appliance. Uh I know

that um people keep asking me what about

DC loads? Well DC loads is not going to

be uh well DC loads nowadays are not as

common as AC loads but it doesn't mean

that it's going to grow. It's not going

to grow. It will be growing. Uh if you

look up um um any like shopping what do

you call it like a shopping websites you

can now find DC air conditioning you can

find DC freezer you can find DC

refrigerator and so on so forth so yes

it's not as common as um AC loads yet

but it is coming right it is growing so

we need to be able to prepare for these

u you know growing numbers of DC loads

all Right. Um before I conclude, I would

like to also kind of mention um

opportunities with IoT and AI. Um IoT

enables sensors, appliances, vehicles

and machines to be interconnected

communicating with each other to

exchange data and perform automatic

task. So um remember I as I mentioned

earlier about energy management systems

um which is a challenge, right? And

nowadays that challenge could be um what

do you call it less uh less difficult if

you can somehow incorporate IoT as well

as AI right um so IoT and AI may assist

in improving efficiency and performance

if you can somehow seamlessly integrated

with renewable energy can do real time

energy monitoring and control to

optimize energy use you can do automatic

um everything right you can do

automatically control lighting, high um

heating, ventilation, appliances based

on occupancy

um and so on so forth. Same thing with

um the grid, right? Since we are

connecting connecting it to the grid,

right? So we can actually have a

communication back and forth between the

house and the grid and ways to be able

to manage energy flowing back or flowing

into the house uh using AI and IoT. So

these are all um uh what do you call it

emerging technology right

and um yeah I mean um

to summarize

um for improved efficiency with

increasing prevalence of DC loads uh we

need to complement the conventional AC

residential electrical system with DC

right otherwise it'll be hard for us to

uh to be able to uh to achieve the net

zero energy hopes right So by having DC

system in our house, we would be able to

um facilitate um um all of these um

energy usage with DC sources making it

more efficient. Right? By doing so, we

can promote the use of renewable energy

and as I said earlier, help achieve net

zero energy hopes. DC has technical

challenges in terms of standards

protection and availability of the DC

loads but this is something that I

believe uh over the years will will be

will becoming less and less of a

challenge. um hybrid AC/DC house which

is the solution that I'm proposing

improves reliability of residential

electrical systems in grid height or you

can also use it as a off-grid type of

applications

IoT and AI younger generation will

probably love this u uh new buzzwords

right IoT and AI can play a major role

in the EMS of hybrid ACDC house and in

estab establishing guidelines for

retrofiting and new construction as well

as optimizing energy consumption. And

finally, hybrid ACDC system is the

future of residential electrical system.

Um, and so we should uh all I would say

put an effort to uh be able to develop

the technologies for hybrid ACDC house

because it is in my opinion is going to

be our future homes, future electrical

systems for our homes. There's still a

lot to explore which is good right u

many aspects to look into um from

technological point of view economic

point of view environmental aspect

social aspect and so on so forth many of

these are beyond my expertise so of

course um it will take a village to uh

develop technologies like this and so I

would really appreciate if you could um

also help right in this effort uh that

would be awesome if we can do

And so with that, um, I hope I can

still,

um, I still have some time to for you to

ask questions and I'll be more than

happy to answer in any way I can. Um,

that is all from me. Thank you for

listening. Um,

Are there any questions?

your institution and your country.

Before asking your question for the sake

of the time, please keep your question

consist and limit to the one and only

question and we will begin with the

first question. Anyone want to raise a

hand?

Okay, Mr. topic said that future

sustainable net zero energy ready home Z

using solar panel right so maybe here

the student and

and the researchers in the electrical

engineering want to ask something about

the ZRH or maybe how to transfer from DC

to A maybe and there are many

opportunities and challenges to create a

new one you and ask everything to Mr.

Si.

Anybody want to ask?

>> Mr. Maybe this project not only

for electrical engineering, right? But

also we can combine all all of the major

all of the department maybe electrical

engineering combined with meing and

engineering or informatic department

maybe. Okay

please introduce yourself first and your

institution.

>> Your microphone please.

Uh, hello. Could I have a question for

you about a

>> hear your voice?

>> Sorry.

>> Okay, you can try.

>> Okay. Hello.

Okay. I have a question for you about a

PLN currency.

So, PLN currency operates on a massive

central institution

>> a secret like the Java Bali system. If

you want to implement DC distribution in

remote Indonesian regions with a low

assay grid reality,

how do we mitigate the significant drop

inherent in DC distribution given our

uni

articulated geography?

Yeah. Thanks.

Okay. Okay. Very good question.

Um Um

>> I'm hitting myself again.

>> You can answer this question. Not true.

>> Hang on a sec. Hang on a sec.

>> Okay. Okay.

Uh that's a very common question that is

being asked about DC is that one of the

dis major advant disadvantage of BC is

that you have a drop right in the line.

Um

so

I think um what I'm offering here is not

it's not the transmission level it's

more on the on the load level

uh because of the restrictions with DC

circuit with the with the drop inage

especially with the distance there are

two ways to

to resolve that problem number one is to

increase the DC voltage

much higher, which is probably not

economical

for transmission

for for a short transmission system.

And so,

um,

sorry, it's kind of annoying

to hear my echo.

Uh,

so the best the best way to me is to go

back to what we call the audition

system.

where the retical system staying within

short amount of distance right so what

we call distributed

distributed energy system so if PALN

wants to do this

>> uh I don't think they can I don't think

it will be econ economical for them to

to transmit DC uh if it's long distance

right um I mean sorry if it's a short

distance it has to be long distance and

when you do that has to be very high

voltage Right. Um DC transmission is not

new. DC transmission has been around for

a long time. But in order to do so, you

have to um do you have to um be um um

be you have to justify the distance the

minimum distance uh to do a DC

transmission and has to be done in very

high voltage. And so again, um the

answer to your question is u if wants to

do this, then they're going to have to

do distributed uh generations, not not

centralized, uh generation, right? Um so

that's that's my answer to you.

I hope that makes sense.

>> How Miss Gasty?

So I think it's enough because currently

operates in a grid like Jelly

distribution and remote

I think is uh enough mic significant

drop inherent in ACC.

>> Yeah.

>> So thank you for your exx.

>> Yeah. I mean if if you like to uh if you

want to learn from um countries like the

US for example they do DC but you know

they they transmit the power from AC

down to DC but then in the DC they use

micro grid it's a micro grid you know DC

micro grid so if if palen wants to do

that they still have to use AC

transmission and then convert it into DC

micro grid you know more localized you

know DC transmission right so there

therefore the distance is going to be

very short for DC

yeah

that's it

okay maybe we will begin to the second

question the second question is from

Zoom chat and the question is how does

integrating rooftop solar panels with a

EMS contribute to sustainability

How does integrating rooftop solar

panels with a EMS contribute to

sustainability?

>> Yeah, I mean it's it's not um

I would say

this is one of those things that um that

you have to uh think about in a bigger

picture, right? uh by using EMS um

energy management system, you're able to

um

uh you you're able to um

what's the word I'm looking for? Uh

wisely, right? You have um you're able

to wisely

um

um coordinate energy flow. There you go.

Right. uh uh with with energy management

system we're able to for example stop

you know energy coming from the grid. If

the house is already self- sustaining

then why do you want to get energy from

the from the grid right um so that that

would make it um more sustainable

because then um we have less fuel being

burned at the power plants which is

coming from a long long way right from

the house right so from that sense it it

would promote um you know sustainability

of uh the of the use of energy, right?

Um and for example, another thing would

be

um

let's see um

if you have excess energy in your house,

let's say you have energy storage,

right? by using EMS. Then maybe in the

future you could ask uh the EMS system

to uh deliver the power back to the grid

but not exactly to to the grid but to

your neighbor right so now your neighbor

is actually using your energy your

excess energy right and by doing so that

would prevent your neighbor from using

the grid right um so that would lower

the cost lower the fuel consumption

uh And the more we have this kind of uh

EMS, the more efficient uh we can we can

be in terms of um energy usage. So I

think um from that point of view um we

can we can kind of we could we should be

able to see that EMS should help in

terms of uh sustainability.

>> And the third question is still from the

chatum. The question is

okay.

>> Oh okay I see

>> very good presentation professor how are

you? Some question from me is why there

is many question here. Why does the

implementation of the DC system in a

country seem difficult? Please explain

the existing problem. Is there still an

opportunity to use the DC system? And

are there any countries in the world

that have used the DC system?

There are three question.

>> Yeah, I can answer the last one. That's

easy. The last one um because I live in

the US. So in the US, we do have a

system that use DC, but it's not pure

DC. Okay. It's um it's hybrid D ACDC.

And so it's been it's been used um

before um

maybe about five years ago I was invited

to help design a DC building in one of

the um big buildings in in San not San

Francisco but is in east of San

Francisco. So they they would like to

use DC system inside their building uh

for

uh for energy for um saving you know

energy basically so they can cut down

the energy bills basically that's what

they're trying to do and so they

understand that having DC is um is

helpful and so yeah um so you ask any

countries use um DC system the answer is

yes um US is one of them um what else

Um,

is there an opportunity to use this

system? Yeah, I mean it's it's the

future, right? It's the future of

electrical systems. Um, you can you can

look it up, you know, more and more

utilities are now running DC micro grid,

right? And with the with the coming of

AI, for example, you know, uh, the data

centers going to suck a lot of energy,

right? And data centers are, this is

just an example, okay, data centers are

running DC, right? And so now they're

talking about having a localized DC

system for data centers, right? Because

if they have to have to deliver power

from power plants, imagine the stress,

right? Imagine the stress the grid will

have if you know if all if all all of

these data centers that are running AI

will have to be supplied by centralized

power plants and so that's not a

sustainable solution. So the more

sustainable solution is to have an

onboard quote unquote localized energy

sources. If that's if that happens then

it's going to be a DC system right and

again if you if you look up um data

centers within data centers are DC DC

system it's not AC anymore right so

opportunity for DC um a lot it's going

to be a lot more right it's going to be

a lot more and I don't know if you

realize it or not your house is using DC

right uh your your LED LEDs are DC right

and so every single light bulb that you

put on the ceiling is actually a DC is a

DC load right and so uh it doesn't make

sense right for every single light bulb

you have to convert from AC to DC so

that's why in the future I think it will

be more efficient if you if you have a

dedicated DC so lots of opportunities uh

with DC as well uh in terms of loads

right um what else

why does implementation of the DC system

in a country seem difficult. Um I think

it's not about techn um technologically

um I think it's

um it's not as like difficult as the AC

um I think they're equally I should say

they're equally difficult I should say

uh AC and DC they're equally

challenging. Uh it's just a matter of um

willingness, right? And people are so

uh content. They're that's just the

nature of human being, right? Uh if it

doesn't if it's not broken, why fix it?

So if they're already happy with AC,

then they're not going to think about

DC, right? So I think it's all about

willingness, right? um if you're willing

to actually do this then it'll be as

easy as putting you know um AC system.

So to me it's it's all about

the will right sort of uh whether or not

this is difficult um um techn what do

you call it technically challenging or

not it's more like whether or not you

want you want to do it you know so and

um if you look at the history of DC it's

been around for a long time right since

uh since Edison system long time ago and

then if you look up you know solar house

we've actually had some uh solar house

program back in early 1970s in

Indonesia. somehow it got stopped right

so I think it's not again it's not about

technically challenging but it's all

about whether or not we want to do this

right and unfortunately it is hard to

find you know people who really want to

do this uh that's been my challenge

actually it's not really on the

technical side but on the um on finding

on finding people who who share you know

the same um passion and interest, right?

Uh to be able to um implement this. So

that's to me the the main challenge.

Hopefully that answers

>> for the good presentation and answer and

Mr. Jamaludin from technical electrical

engineering. Mr.

has answered your question well and

maybe it's a final you can explain to

the audience here about the chance for

collaborating with any other department

maybe in any department you can ask

explain as well as you know

>> yeah yeah

u if you if you remember the picture

that I've uh shown you a house remember

the net zero energy house um That house

um as you know is built from different

you know different technologies

basically right it's built upon

different technologies not just

electrical but also uh mechanical when

it comes to DC you can look it up for

people who are from mechanical

engineering department for example you

could um contribute in in the DC uh

system by helping us with the heat pumps

So if you look up heat pumps um I

mentioned earlier about digital

electricity that's um that's a very new

technology. If you're interested in uh

contributing to uh future hybrid AC/DC,

go ahead and look up uh digital

electricity and over there if if you um

read it um one of the challenges would

be from mechanical engineering uh aspect

which is the heat pumps and then um as

you know a house is being built from

materials right so how do you make a

house more sustainable right more not

just more sustainable

um energy efficient. There you go.

Different materials would be able to

hold, for example, if it's hot day

outside, you do air conditioning. How do

you make sure that the house can keep

the cooler temperature longer, right? Um

maybe by having different materials,

which I I don't know what it is. And

then from uh architecture

point of view, you have to design a

house that would have a good airflow,

right? A good uh way to um let sunlight

get into the house without heating up

the house, right? Things like that. So

um and then of course you know computer

science man uh that's a lot that you can

actually develop from computer science

side right from the software uh point of

view uh as you know as I as I tried to

explain earlier in terms of um what do

you call it EMS in terms of how do you

communicate between the house and the

and the grid how do you communicate

between houses if let's say two two when

two houses are connected with hybrid

AC/DC house network how do you make the

two talk to each other right through

software which I I don't know how to do

it but that's uh that's why we have

computer science people to help

yeah

presentation here maybe still many line

of question but the time is limited so

we can answer it with the next ICC app

in the ICC app ICS

ET6 2027 maybe and we can go to the next

presentation thank you very much for

your presentation Mr. Tophi

>> thank you thank you for the opportunity

>> and we go to the second question second

present presenter here

thank you very much for Mr. here has

become a present the presentation very

well today and now we begin to the

second keynote speaker and our second

keynote speaker is professor Yasu Musasi

Kumamoto because of time limit I only

highlight the recent and significant

achievement from his impressive academic

profile rather than regarding their

complete curriculum fight and time is

yours Mr. Kumam Mr.

Yes. And the time is about 25 until 30

minute for presentation.

Welcome

>> Mr. Yasu Mousasi. Time is yours.

>> Okay. Okay. I try to set up my

presentation. Um PowerPoint. Uh middle

weight.

Um

and this one

and

let's go slide show.

Okay.

Uh, did you see me?

>> Can hear your voice and your

presentation.

>> Did you see me?

>> Okay, you can start your presentation.

>> Oh, okay. Thanks. Excuse me.

Um

um I am uh the cyber security uh

scientist and working at Kum University

uh many many uh uh institute I was

belonging at um so uh many many

next years um maybe next year so two

years later I I also belong to one more

another institute

don't exactly name of that

uh so but mainly I am uh working at the

center for management and information

technologies

uh CMIT in Kumo University

and uh my title is uh uh how DNS cyber

security study can contribute to the

support the sustainability

energy and food security in the digital

era

And I got this uh invitation from um

this uh chairman uh this uh conference

chairman and uh I readed um some uh

support and system energy and food

security in this era. This topics

the for the first time topics for me uh

system energy and food security is for

the first time things. So I I get

started is from April to uh

today's July 1st I run the um study

about food security and uh what is uh

sustainable energy but uh my my

presentation is uh is like a beginner

levels so

please uh uh take into consideration

about

T of type of contest something like

this. Hawaiian cyber security and

supporting uh sustainable energy

ensuring food security a broader

societal impacts watch survey detections

about net digital communication and

robust net detection using explanable AI

and press or synto models and the

feature engine ring for XAI plus or

models

and etc.

The how come DN cyber security uh DNS

cyber security study uh contributes uh

directly to the sustainable energy and

food security

uh by protecting the digital

infrastructure that controls modern

power grids and agricultural supply

chains.

And the first uh um uh reference says

something like that and modern critical

infrastructure relies on the heavily on

connected industrial uh control system

IC and internet of things IoT devices.

Professor Tafi uh talk about the uh this

type of systems and DC power and because

a domain name system is is a

foundational routting mechanisms of the

internet and securing it ensures the

uptime and safety and efficiency of

these uh vital sectors.

and supporting sustainable energy. The

securing smart grids uh distributed

renewable energy uh you know that the

solar panel or wind ting on uh DNS uh to

uh root realtime data uh between the

smart meters and central management

systems.

uh securing DNS prevents dockers from uh

hijacking this connection or temp we

tampering the this connection to the

cause of blackouts

and preventing operational downtime

malware and ransomware often uh DNS for

command and control

uh C2 communication uh DNS monitoring

stop ST before hackers can shut down the

wind farms over nuclear cooling systems

and uh

ensuring the food security.

protecting precision agriculture.

Modern farms use IoT sensors for

automated irrigation. The soil

monitoring and drone mapping and secure

DNS prevents hackers from uh tampering

with a sensor data and which uh could

lead to ruined crops.

Uh secure rings is the food site chain.

Uh logistics networks use a DNS

dependent CR software to the fact

for shipments

of up time and the food does not often

in transit due to uh routing

disruptions.

uh defending agricultural

biotechnology farms store critical data

on the road resistant crops. Uh there

might be a possible that DNS security

protocols like a DNS set prevent data

theft by DNS turnering and cash

fingering.

Uh broader societal impacts

uh mitigating geopolitical risks. The

food and energy are primary targets for

the state uh sponsored cyber warfare. A

robust DNS security acts as an national

deense mechanisms for the essential

resources.

uh reducing electroic waste and uh

several attacks that the physical uh

damage the grid at har

industrial farming

uh

equipment rel to the premature equipment

replacement and electronic waste to the

software projects the physical assets

uh recently uh N special publication 800

how international frameworks are

advancing security.

Uh the new security framework

SP881 division 3 was published of Shi at

19 this year uh March. A name system

name system DNS deploy deployment guide.

The AR conference student 25

described key highlights of NIS 881

revision 3.

uh DNS zero trust policy enforcement

and privacy and the protective DNS as a

network defense layer

and uh it is concluded as follows

recognize DNS as critical National

embedded genus is in a risk frame banks

and harmonized the standards and scale

through the collaboration.

So f uh summary of I forget to prepare

the summary of that uh um

this uh list hand or food security or

something like that and uh at this

moment is uh I'd like to summary uh DNS

maybe uh DNS security uh DNS security

can uh support and uh food uh security

and uh sustainable energy. uh because uh

uh ICS systems and agri uh culture agn

uh infrastructures

and the DNS domain name system is uh

support is

uh these uh ICT infrastructure crowd

system web applications

uh six years ago

uh my uh student

get started. This is a uh reload survey

about the cyber security

um in 2019

review of cyber security research topics

and taxonomy and challenges. So

classifications of the uh what kind of a

cyber security topics

uh is uh attractive at this moment at

that moment and uh uh in cyber security

science applied cyber security cyber

security data science and cyber security

education and training and cyber

security instance and cyber security

management and policy. cyber security

technology and human social cyber

security and theories in cyber security.

So uh many many uh cyber security uh uh

models or scientific models approach

model uh we are uh concentrated the uh

data uh mining or data uh science about

that

>> domain name uh you know that the

google.com.acid

acid

uh they are um and we call it the domain

name

and uh domain name is converted to uh um

IP address a very simple uh database

systems distributed database systems

but this uh why we need uh domain name

systems uh because uh CPU computer can

the start is only digit numbers. So IP

addresses consist of is a digital number

a a dot b dot c dot d dot and a bcd uh

is 02 from 0 to uh 20 255.

So very simple uh uh uh database systems

or communication um domain name system

is very simple uh database systems and

we uh we uh set up this DNS server and

the internet on the internet and uh DNS

client like a web application brow web

browser email uh exchanges email server

is uh consuming this DNS uh uh access a

DNS server to uh convert it a domain

name into uh I IP address

and I DNS communication is uh

uh

and in cyber security is nowadays is

very popular and but uh

very legacy and uh this services get

started from 1970

And uh we uh get started to maybe around

is 19 94 or around is a um internet DNS

is get started in the um public internet

and they uh get started to and uh uh

host IP uh combines your systems DNS

domain name systems or something like

that and uh and on the other hand the

DNS test is uh communication is uh using

using only very small packets uh we call

it the UDP packet uh 512 bytes only and

this packet is uh exchanged between and

the domain DNS server and DNS client we

connected

uh the website or web applications and

initial stage this DNS is consumed

Anyway,

and DNS is

maybe very quickly uh tweeted

should be very quickly uh tweeted. So

firewall systems or broking system is uh

ignore DNS uh communication nowadays

and uh both you notes is uh malware

hijacked the PC uh botnet infected

laptops and this uh PC is not not

laptops is including all of the computer

systems is they are using this DNS

systems and uh this uh uh hijacked PC or

attackers PC uh through the firewall

and connected to the uh CNC servers or

static domain name

and uh difficult to broke since it using

CNC server domains generated

algorithmically

and the normal uh uh unmaricious or

estimate uh domain name is uh uh

registered to the u root servers. So we

can uh uh freely access that this uh

communication and the CNC is the direct

communication very difficult but uh DNS

is uh allowed to uh pass the firewall.

So uh this uh domain uh generation

algorithm communication is uh possible

the domain name created by human a

domain name generation algorithm domain

created by the machine.

So google.com

id is uh very easy to u pass this u file

systems and also uh we cannot uh notice

this is not uh is not DJ or Maria

communications. So this is an example

something like that very difficult to

read but that they including some code

or encoding some text message programs

and the botet is cross the hijack to

computers. Uh we uh so attacker is um

hijacked the uh computers and to the uh

do some uh uh cyber attacks

and uh

in our laboratory is u prepared and

studies about the DJ detection.

uh we title is the lowest botn net

detections a vending xi and our center

for seas threat intelligence share.

So uh in from the 2004

uh to this uh to NT26

our institute is uh looking DNS query

from the DNS client DNS server is

correcting is a DNS query. uh what kind

of a domain name is uh resolved and what

kind of IP address is assigned

and uh we com uh combinations of this

cyber intelligence

uh indicators of compromise wasn't or

opensource intelligence

uh very famous uh cyber scientist is uh

using this as a cyber threat

intelligence site um uh this is virus

total and I've I've used IPDV as a best

very common and they have as a database

of the DGA data set and IP address and

it's executable files

and abuse IPDB is a IP

site.

So um in 2019 around so covid-19 times

uh our web communication is uh uh

encrypted.

So cyber scientist or cyber uh security

study uh we try to view the payload of

the uh observe the pocket head only. we

can only uh observe the packet headers

because the inside is encrypted. So very

difficult to uh the code or the equipped

uh by so if we can get uh uh encryption

key code.

So we can only get this packet headers

IP addresses and or domainers

unfortunately

and we need fusion of AI machine running

and CTR O. So IP address side

information or related information uh

can be available from only uh this kind

of CTS site nowadays.

It get started advances

um digital transform uh error uh web

application or web traffic is encrypted

very difficult to view inside

and uh normal

uh AI ML but explainable AI ML

uh except AI

uh ex uh printable able artifi

techniques amongst the results of AI

model can be understood by humans

explaining why an AI arrived at a

specific decisions.

uh now uh a conventionary AI machine

learning models are using the feature

engineering

and otherwise you know and and on the

other hand uh deep learning is de around

2015 or 2017

deep can uh

without uh uh preparing a future

engineering it's a directly uh uh eating

uh running uh datas and uh uh they also

using some uh inside

and black box. So we cannot see the what

is going on but uh uh accuracy uh some

classification across is very good.

So Ximar AI is automatically

uh so deep learning cam

uh deep learning cam uh explain

uh difficult what's going on in the

black box and the conventional uh

feature engine based uh AI can explain

and uh what kind of a feature uh is

uh

important or not

and uh computer paradigm uh to the best

of our knowledge. No research

highlighting importance of sharing AI ML

models for CTI has been published.

uh CTI uh is uh report based for an

example this abuse IPv is a reported so

uh some hackers is reported this IP

address is very uh malicious

and uh this uh

IP address was found in our database

this IP was reported 473

times So we are confidence of abuse is

100%. So scoring 100%.

As this way uh we can uh correct the IP

addresses malicious IP address from the

uh this CS site and also we uh deduct

some IP addresses reputations and to uh

raise up the um

accuracy of them. So we can feed back to

the uh CTI models to uh CTI again to the

reported automatically uh using the uh

uh web API or something like that

and uh we also is preparing XAR systems

and data sets and features.

So uh features is uh entropy. So AI

system or machine learning we always is

employ

uh feature vest engine is entropy

relative entropy.

Uh this kind of the seven features

and the k square test results or

correlation matrix analysis results. Uh

this results shows is how these uh

features are correlated or not

and uh feature engineering accuracy how

they uh change uh using like this way.

So feature uh all the feature is

contributes

higher accuracy or is uh only the

computations

and the future importance analysis and

results. A random forest uh machine

learning model can uh prepare this kind

of XG boost is also uh prepare this kind

of uh importance analysis results

and accuracy is uh um 99 or 998 uh is a

very good accuracy

and the fusion of XAI and Ointo using

this JSON models

and uh explainable AI as if you use is

expi

and Python or uh Google cra or something

and AI systems that you can um

automatically this kind of rhyme uh

analysis

and uh complexity of the time

the time is is okay.

So uh we are doing is uh uh many u um

machine learning model to arogix uh

regressions random first night base and

extra tree and some

random first is always a good results

and the feature uh to selection to the

four features or five features. There's

six features, seven features

and also accuracy resultant and we are

uh increase

the accuracy or something like that

and to the calculated computers is what

what what feature which feature is most

important and the high contributions or

and the constraint uh uh analysis

but these uh analysis method are running

models or feature sometimes is a bad

accuracy and this is something in the

problem

the our uh data set and code are

available in ITP data port if you are

interested about our uh

uh

study results the first access

and the DTA uh for operation

uh KG DJ data set DJ data set uh CSV or

DJ websites CSV is available for a

simple uh pattern matching

uh but this data that is uh 8 80,000

uh DGA and uh register is uh 80 so six

160,000

uh rhymes uh for uh this DJ data set.

Well, thank you very much of my

presentations.

Question and answer session. Participant

who wish to ask a question are kindly

request to use raise hand feature or

type question in the chat box. And when

your name is called, please introduce

yourself by mentioning your name and

your institution. And before asking your

question for the sake of the time please

keep your question concise and limit

into one question only and we will begin

for the first question anyone to ask

please raise your hand.

Okay maybe

there is one question in the chat box.

His name is his eidel.

Excuse me professor. I would like to ask

why DNS security only protects something

from malware but the software can still

be injected into a laptop or cell phone.

Even though DNS security has been

activated especially in the browser when

downloading even though DNS security is

activated sometimes it still get true.

Why like that? Maybe

you can answer.

>> No problem.

Uh this question is um I'm just reading

injected into the after the cell phone

uh s can still read injected into the

laptop for the cell phone even zodia

security has been activated especially

in in the browser when the downloading

even zod security is activated sometimes

it still gets through the why is that

okay uh this question is a very uh very

good questions because um

uh still not yet uh implemented our

internet because DNS is uh security is

uh quite difficult

uh because uh we uh broking DNS

communication. So uh internet

communication uh immediately done. So we

cannot connect it anymore as a how broke

or how detected malware from the

security at this moment and in our study

results uh show that uh uh they are uh

maybe uh uh detected may be detected and

uh this this communication or this uh

behavior is maybe malware based

but Uh

yes and uh uh which uh IP IP address is

can be available. Uh we can detect is

the IP address maybe this uh IP address

is is a person uh a PC and or smart uh

phone or something like that. So we can

identify this as a devices may be okay

but uh maybe uh infected or not. So we

need uh uh if we uh uh detected how they

are distributed by uh through DNS uh uh

protocols. Uh that is a big questions

and big uh problems. If you have as

implemented this uh receiving uh some uh

uh

our distributed packet or chain

information from that. So we have to

anyway prepare the this kind of

distributing uh information that your

PhD is uh infected but how uh

distributed using the gen through the

genus protocols. So that is the big

questions. Uh fortunately uh this year

March uh NIST uh special publication is

uh um updated and uh uh NIST 800

uh

13 uh division 3. So we our uh DNS uh

related uh uh ICT uh enterprises company

maybe they shifted to uh following this

uh NIST 800 uh 13 uh release

uh that's my answer that I can say

the Second question is from the chat box

also in the J meeting. Good morning

professor Yasu. I would like to ask

about trend in data science and

artificial intelligence professional. In

your opinion, how will these two field

evolved and what will be required in the

future? Thank you.

uh data science

ask about translation data science and

artificial intelligence professional in

your opinion how will these two fields

evolve and what will require in the

future

uh is a very interesting questions um

and I'm just in the searching

I'm I'm just the research it's a good uh

research topics

I'm just in studying line and that's my

questions. Uh that's my answer for that.

>> If you have a solution

please

may I ask question?

>> Yes.

Oh,

you don't want Thank you.

>> How are you? How are you?

>> I can hear your voice.

>> Hello. You You can hear my voice now.

>> Yes. Uh

>> yeah yeah yeah I am okay.

>> Okay. Uh may I ask a question?

So uh

uh today is era of uh

postquantum cryp uh cryptography pc.

So is uh DNS security mechanism is we we

need to upgrade it to adjust with the PC

topics or uh because computer uh quantum

computer is not has uh has not been

built yet

is it uh also a good research topic

about uh upgrading our the the NS

mechanism to ptopic

>> sensei

>> so that's my question

>> your question The quantum computing is

what kind of the contribute for the DNS

security.

>> Yes. Yes.

>> Mr.

>> Very interesting questions but uh

quantum computer still under broking

now.

Oh

yes. Okay.

Yes. So uh DNS mechanism is a good topic

to also now but uh as we know that uh

today's

uh we talk about PCA right because NIC

already uh released the standard of

postquantum cryptography

you

you hear my voice

>> yeah I can hear no

Uh

>> you you mean uh counter mechanic?

>> Yes. Yes. Yes. again

I'm just in the running is the quantum

computing and uh um I'm prepared several

uh papers for that but uh still are

developing that that I can say

I see thank you sensei

>> thanks

Uh yeah, thank you ma'am.

>> Thank you ma'am. I can can't hear you.

>> Hello.

>> Hello. Hello

>> Mr.

>> Hello Mr.

How about the answer?

>> Yes. Yes, Mr. M.

>> Sorry, I uh I'm not

>> you satisfied about about the answer.

>> Yes.

>> Okay. Maybe this is the last question

for you Miss Professor Yasu. How to

improve data security or data

enscription so that the important data

in laptop cannot be tried or hijacked by

unwanted people.

>> This one is okay.

>> This is the question from the chat box.

>> Yeah. Yeah.

uh excuse me professors as a civil

engineering student I I am particularly

interested in cyber security and smart

infrastructure in your opinion how can

the cyber security enhances the

resilience of smart cities and critical

infrastructure such as smart water uh

distribution uh systems and then okay so

uh I I talked about the ICS systems and

uh this system is depend on is a crowd

and the crowd infrastructure is uh on

the uh data center and this devices is

using uh finally uh uh web

communications or web trusted

communications and the web communication

is uh um uh don't use uh they don't use

uh uh directly uh IP address itself

themselves always they in initial stage

or uh to make some web communications

and they also al also name resolutions.

So always they use is a DNS and domain

name systems anyway. So DNS is always is

available. So availability is very

important on the uh DNS services. So

because all the systems internet system

is uh based on stand on the uh domain

name systems. So how uh contributes

uh how uh does it does it contribute uh

to the uh uh water or uh intelligent

transportation networks. So all the

systems is uh uh strongly depend on the

DNS systems.

Uh so we have to secure the DNS

communication anyway. Uh that's my

answer is okay.

Uh, could you satisfy?

>> I'm sorry I could hear

>> in informative department. How to

improve data security or data

enscription so that the important data

not be retreated or hijacked by unwanted

people? How to improve data security?

Professor

>> the f first uh uh initial stage of the

question is uh uh this one this one

excuse me which one

>> book but in here

>> which

I'm sorry I can't hear

Oh

>> you can hear my voice yeah Okay. Okay.

>> I'm sorry I can't hear.

>> The question is in here. The question

about how to improve data security and

data encryption.

>> Uh data security and data encryption.

Uh this question is

>> uh the question

can can I answer

>> I mean

>> data security for the important data

maybe

>> in laptop or in smartphone

>> uh data security

>> maybe like a banking data or another

ones

So keeping integrity integrity integrity

>> and uh

ability

>> and we we always is a construct is the

CIA uh confidentiality

and availability

>> and the data security is uh need need

encryptions anyway. So encryption is uh

one of the very important but uh uh we

doing uh data encryption and also quick

access to the this kind of a data uh

nowadays is a very important uh subject

to solve

>> just

working

because Yeah. Yeah.

>> Okay. It's okay professor. Thank you

very much for your answer and thank you

very much, professor, for your

insightful presentation. We wish you

always success in the future and we look

for we look forward you meeting you

again in the future in the conference

ICS

2027. We hope to meet you again in the

next conference and maybe if there are

still any question the students or the

audience here will call you in the next

agenda like this. Thank you professor

for this meeting and we go to the next

to the third presenter.

Our third presenter is professor

Dr. Ing Ali Buono MPM. Maybe Mr. Ali

Bawono

in Zoom today. I will ask and say hello

first.

>> Hello.

>> Hello Mr. Ali Bono.

>> Yeah. Hello. Hello.

>> Okay. Before I introducing our

distinguished speaker, I would like to

note and underline due to the time

constraint, I will highlight only the

most recent and significant achievement

from the from his impressive academic

profile rather than regarding their

complete curriculum.

And before Mr. Ali present about his

presentation. I will read about his

curriculum fight

Dr. Ing Ali Bawano MPM from the

technical university of Munich TUM Asia

Singapore.

I will read about the detail of

education.

He has studied doctor in civil

engineering

technici university at Munson TUM

Germany and he has studied a master of

science in transportation system techni

tum Germany and he is also has studied

bachelor of science in civil engineering

institute of technology bandongbe

Indonesia and about academic experience

from January 2023 until present he is

senior researchers and lecturer in

faculty of rail and urban transport and

logistic MGMT and he is also head of P

AI initiative lab performance and agile

green infrastructure and he also have

published international patent to

technology disclosure and more than 10

10 paper review papers and including in

the top of three Q1 journals very good

and amazing

And thank you Mr. Ali Bawo. And about

presentation 25 until 30 minutes time is

yours.

>> Are you ready for presentation mister?

>> Uh yeah sure. Uh okay. So before I start

>> should I speak in uh English or

Indonesia? Indonesia.

>> It's up to you. If you okay in English

you can presentation in English or in

Indonesia it's okay.

>> Okay but most of the students are

Indonesian or

>> audience here is Indonesia but there are

sometime somes in from foreign.

>> Okay then

let me just just uh

>> present in English. Then if anyone wants

to ask

in Indonesia please feel so

>> yes it's better then

>> okay sure thank you so much so much for

university

Joe for inviting me it's a a great

pleasure I would like to thank you for

the uh director for the academies and

also the committees and last but not

least for all of the students uh

participating on this uh international

conference. Yeah, I really appreciate

that University of Muhammad Sidorio is

really uh have a good positive event.

Yeah. Uh of this kind of international

conference which I hope also giving some

international impact. Yeah. And I hope

that some of you later on u I don't know

maybe some of you can decide whether you

want to pursue your career in Indonesia

as well as in international. Yeah. Okay.

So uh I think as mentioned by the host I

have uh 20 to 25 minutes yeah to give

some uh keynotes uh speech. Yeah. So I

will not uh get into deep yeah uh about

my uh research my projects in in

Singapore as well as in uh overseas.

Yeah. rather to I I would like to

summarize what is I I believe is is very

important uh for all of us yeah not only

in Singapore uh but also uh to all of us

yeah especially uh you guys in Indonesia

is still doing your studies which I

think later on you can use this kind of

uh uh knowledge and principles yeah to

be utilized yeah to be uh enhanced yeah

uh when you are going to uh work in the

industry in the authorities and so

Uh so uh yeah my topic is uh sustainable

resilient and smart infrastructure and

uh I I am trying to bridge uh uh a few

different topics uh between innovation

technologies and global impact but uh

first of all I have to apologize that uh

uh my uh as you can see from my

background I'm not really uh focusing

into energy or neither uh yeah but

rather focusing on civil infrastructure.

Uh that's why my topic will be focusing

on infrastructure. But I think if you

see uh and if you listen later on uh my

my uh keynote speech or presentation

yeah you will understand that that the

principle of the things is actually

quite applicable to uh different

sectors, different industries and so on.

Yeah.

Uh okay. So this is the topic and uh

yeah just uh to I just want to I think

you already have some uh background of

me but uh I just want to give you some

highlights about TM. Yes. So theium is

actually is university uh headquartered

in Munich in Germany. Yeah. So we are

one of the uh best well in fact we are

the best in Germany in terms of

engineering university. Yeah. And we are

also one of the best in in Europe

basically. uh

uh and uh TM we have uh several campuses

actually. So uh we five of them we are

located in several cities in Germany but

one the six campuses is actually located

in uh Singapore which uh I am based here

actually and then in Singapore we have

two entities basically which is tomb

Asia which is focusing on the education

and then we have a research arm which is

tomb create we are focusing on uh

research and development

and yeah a bit of background I think uh

the host is already uh explained uh so

as you can see from my background I'm uh

trained uh in civil engineering

and yeah I'm still uh active uh doing

some publications books uh and some

patents and so on

and also uh currently I'm heading uh

initiative called pagi which is uh

performance and agile green

infrastructure where uh we are our team

yeah uh focusing on road uh highway

infrastructure rail infrastructure

but also on the transport systems. Yeah.

So yeah, maybe uh one of you uh

interested to study in in Tomb Asia in

Singapore or to in Germany, please uh

later on you can approach me, send me

some emails. Yeah, then maybe we can

have some discussions. Okay. So let's go

back to the topic. Yeah. Uh well uh I

would encourage everyone to uh enjoy

yeah the the discussion. So you can

interrupt me anytime. Yeah. Uh if you

are curious with some of the figure with

the charts or with some statements in

this chart, you can interrupt me uh

anytime. Yeah. Or otherwise you can also

ask me after my presentation. Yeah. So

this is the agenda the outlines that I

would like to share uh with all of us.

Yeah. The first one I would like to

remind all of us including myself. Yeah.

That we have a big challenge here. We

have a very huge challenges. Yeah. not

only in in Indonesia but uh in general

globally.

So after this uh I would like to share

some of the sustainable uh practices.

Yeah. Is about the sustainability how

actually uh we as a engineer we as a

student we as a agent of change. Yeah.

Can play a big role. Yeah. In in terms

of sustainability which is covering all

of the three aspects. Yeah. from the

economic, society as well as the uh

environment. Yeah. And then last but not

least, I wish uh I will share some of

the technological advancements. Yeah.

Which uh if you are uh following some uh

global news, yeah, that uh you might

know that the Singapore is actually one

of the global hub. Yeah. In terms of

technological advancements. Yeah. So if

you are curious about foods, if you're

curious about uh transport,

infrastructure, energy, finance, yeah,

you you you might find the best of the

or the role model is actually located in

in Singapore. Yeah. So that's why uh if

you are curious, I I would like to

encourage you uh to to come to

Singapore. Yeah. Uh just to see from

different perspective then uh yeah. And

then last but not least uh is a call to

action not to not to you. Yeah. But uh

actually to all of us. Yeah. Okay. So uh

so this is uh our challenges. Yeah. So

uh there are many of course there are

many uh challenges. Yeah. But in terms

of uh uh infrastructure and so on. I

think this is uh the three main uh

challenges that we are facing now

especially your generation. Yeah. So the

first one is a climate change. Yeah. And

uh unfortunately we have a low uh

resilency uh level. Yeah. In many

different sectors. Yeah. And then the

second one is urbanizations and

population uh growth which you might

think urbanization is is good. Yeah. And

of course it's good in terms of

economic. Yeah. Of course all of us

wants to move from let's say to rural uh

place or remote place to uh urban place

because we want to uh achieve something

better in our life. Yeah. So to say in

terms of economic, in terms of

lifestyle, in terms of different aspect

like for example society and so on but

this kind of urbanization is actually

also giving us some negative impacts

basically. And last but not least is uh

resource scarcity. Uh Singapore

unfortunately we don't have a lot of uh

resources. Yeah. But then uh if you

notice about Singapore we the country is

actually very rich. Not because of the

resources. Yeah. But then because of the

capability, because of the human

resources and so on. Yeah. And

unfortunately uh well myself is actually

Indonesia. Uh so I'm uh unfortunately

I'm also sad that uh until now uh we we

can see that in fact Indonesia is is

very rich in terms of resources but

somehow we don't really utilize this

optimal. So

uh that's why later on you you will see

uh from some charts and so on that we

are actually having a a big challenge

here.

Okay. So yeah these are some of the

pictures. Yeah maybe from our daily

life. Yeah. So some of the picture is

actually not uh from Indonesia but uh

from our neighboring countries like for

example India, Vietnam and so on. So we

are actually facing the same challenges.

Yeah. Like for example a flooding and

then typhoons and so on, earthquake and

so on. This kind of uh damage of course

is affecting people and resulting in

economic losses. Yeah. And of course uh

later on you will see that this kind of

damages is actually also coming from the

climate change and so on.

So this is what I want to uh highlight.

Yeah. So the climate change and temporal

challing is actually is very real. Yeah.

So and

significantly affecting our

infrastructure. Yeah. So if you see from

this uh uh chart Yeah. or pictures Yeah.

you will see that uh more than 15

billions annually is actually damaging

our infrastructure. Yeah. But then what

is uh interesting more than half Yeah.

more than 50%. Yeah. The the damages is

actually occurred. Yeah. in low and

middle inome uh countries. Yeah.

Including Indonesia. So that's why uh if

we have like uh in terms of residency

rather low and then sustainability is

also quite low then we are actually uh

receiving the the the biggest impact

actually in terms of this kind of

damages from climate changes. Yeah. So

to say earthquakes, cyclones, floodings

and so on.

Then uh this is just some numbers. Yeah.

But then if you Google it, if you are

using AI, if you read some newspaper,

you will see that this is actually you

can see this in in your daily life in

your newspaper, in the magazine, in your

mobiles, in in your Tik Tok apps and so

on that actually a lot of damages, a lot

of incidents, a lot of casualties. Yeah.

not only Indonesia as I mentioned but

also in Vietnam, Thailand, Malaysia,

even in Europe, even in in uh North and

South America, even in African

countries, Middle East uh and so on.

Yeah. And then you'll see that the

numbers is actually is is is very uh

high is it's huge. uh uh so if we don't

really care about uh ourself about the

roles that we are taking uh later on in

the future after you are graduated then

we will be really in a mess situations

basically

and uh the second thing uh urbanization

yeah apart from the climate change so

urban urban population is growing

rapidly yeah so if you see from the

statistics yeah is projected to grow

from 4.4 4 to 6.7 billion by 2050.

Unfortunately, as you can see from this

uh slide, yeah, this kind of initiation

is account for 70% of total global uh

carbon footprint. Yeah. Or CO2

emissions. So the number is actually is

very high. So that's why uh I'm I'm not

blaming the urbanization because uh even

myself Yeah. I'm expecting to have a

better life and so on. Yeah. But then of

course if we don't uh do what we called

as the sustainable uh practices then uh

we again we will be in a mess situations

basically.

Then uh here are some facts basically.

Yeah. Uh this kind of rapid and unc

uncontrolled urbanization. Yeah. Uh

brings a dramatic uh changes. Yeah. And

most often negative. Yeah. So as you can

see from some of the statisticia it's uh

resulting in 70% of natural resources uh

consumption up to 80% of energy

consumption 70% of greenhouse gases more

than 50% of waste productions. Yeah. And

so on and so even is eventually it will

cover some uh or damage some uh natural

habitat. Yeah. And then of course uh

many uh studies found out that this kind

this kind of urbanization is affecting

the loss of the biodiversity in urban

areas. Yeah. Threatenings the function

of the ecosystems and so on.

But then what is uh interesting uh again

doesn't matter later on when where are

uh the industry that you are working on.

Yeah. Because this is uh is a global and

is uh affecting various of industries

and sectors. Yeah. So if you see from

the left chart yeah on the y-axis is

about the uh material footprint. Yeah.

Is about the GDP. Uh and then on the

x-axis is about the population. Yeah. So

you will see that the trends here first

of all uh the population is increasing.

Of course this is normal. This is makes

sense. Yeah. And then uh what is uh

interesting here is uh the material

footprint is increasing. Yeah. Which is

makes sense more people then we need

more uh resources. Yeah. for your uh

let's say for your clothes, for your

houses, for your uh public transport,

for your phones, for your laptop, uh

everything that you use for uh your

daily life, for your work, for your

studies, for your uh societal uh

activities and so basically we need uh

this kind of material. That's why you

see the material footprint is increasing

uh significantly.

Then of course if we have this kind of

uh resources being

uh utilized yeah we are expecting that

the economy yeah in general will also

increasing which you also see in the

yellow line. But then what is uh

frightening yeah uh for me and for a lot

of people unfortunately the economic is

not increasing

uh linearly. So you'll see that the the

material footprint is increasing uh in

the gray line but the GDP is increasing

at at the beginning is is quite the same

uh in fact is more than the material

footprint itself. Yeah. It means the

economy we extract resources and then

you generate more economics values.

Yeah. But then after sometimes you will

see that the the gap yeah between the

material footprint and the economic is

rather bigger bigger and becoming even

bigger. Yeah. So this is actually uh a

clue for us that uh we are not uh

utilizing our resources uh optimally. We

waste a lot of thing. We waste a lot of

resources. We uh do uh many things that

not inefficient. Yeah. So that's why the

economy now is actually is becoming uh

bigger.

Then uh I also have the second chart

which is uh coming from the

international resource panel. Yeah. So

you will see that here are there are

four different types of material. Yeah.

The fossil fuels, the nonmetallanic

minerals. The metals as well as the

biomass. Yeah. So you'll see the on the

y-axis is about the extractions again in

million tons. Yeah. And on the uh x-axis

is about the trends. Yeah. From 1970 to

uh early

about 2020. Yeah. So you will see that

the extraction is again increasing and

increasing almost for all of different

uh material. But then what is

interesting here on the second yaxis you

will see that the material productivity

yeah at the beginning in 1970s in 1980s

the material productivity is is good.

Yeah. Is increasing uh in a positive

trend but then after 1990s then the

material productivity is becoming a

stagna. So you can imagine we extract

more material. Yeah, we extract much

more material than before. But then the

productivity is remaining the same. So

it means uh if you see from the status

we we start to notice hey there is

something wrong. Why we are extracting

material more material but then the

productivity is stagnant and then you

see from the previous chart the economy

also increasing but not uh from is not

based on what we are expected. Yeah. So
