This is indeed perhaps
0:01
we are already familiar
0:04
with the name of protected forest
0:07
what is actually a protected forest
0:11
so a protected forest is a forest that
0:14
functions to protect the
0:18
for example to prevent flooding regulate
0:21
water management prevent erosion
0:24
maintain soil fertility and prevent
0:27
sea water intrusion into
0:35
then How do you make a
0:38
forest be designated as a
0:40
protected forest a forest can be designated as a
0:44
protected forest if it meets one of the
0:46
following criteria first
0:49
Forest area with the results of the calculation of the
0:51
slope class factor of soil type and
0:55
rainfall intensity gets a score of 175
1:00
second Forest area with a
1:03
field slope of 40% or more third
1:07
forest area located at
1:10
an altitude of 2000 m or more above
1:17
forest area that has soil that is very sensitive
1:19
to erosion with a field slope of
1:22
more than 15% and fifth
1:27
forest area which is a water catchment area
1:29
and sixth forest area which
1:33
is a coastal dam area
1:36
So if the forest area has met
1:39
one of the six criteria
1:41
it can be applied to become a protected forest the
1:46
criteria in determining the protected forest
1:49
take into account three factors namely
1:53
field slope soil type according to
1:56
its sensitivity to erosion and
2:01
we will discuss one by one the first
2:04
is the field slope slope
2:07
0-8 percent is called flat marbles
2:11
that are 8-15 percent are
2:17
Hi, the 15-25 percent marble is rather
2:24
25-40 5% slope is steep and
2:28
the slope of more than 40 5% is called
2:31
very steep. The second is
2:34
the type of soil according to its sensitivity to
2:39
soil erosion that is classified as insensitive, namely
2:42
the type of alluvial soil, Glee planosol soil,
2:45
gray hydromorphic soil
2:46
and it turns out that the groundwater is
2:49
quite sensitive, namely the type of latosol soil.
2:53
Hi, there are also types of Brown Fals oil
2:57
non-calcic Brown and Mediterranean soil.
3:01
He admitted that the soil included in the
3:04
category is sensitive to erosion, namely the type of
3:07
andosol laterite grumosol latosol
3:09
and futsal League soil. The types of soil
3:15
sensitive category are the types of regosol litosol
3:19
organosol and rendzina soil. Third, we
3:22
discuss the intensity of cendet
3:26
rain, namely the average rainfall in
3:28
millimeters a year divided by the
3:31
average number of rainy days a year which is
3:35
divided into the following classes:
3:38
rainfall intensity below 13.6 is classified as
3:44
rainfall intensity. 13.6 to 27 is included
3:51
rain intensity category.
3:54
27-27 point seven is included in the
3:57
medium rain intensity category. 27
4:02
7-34 point eight is included in the
4:05
high category and rain intensity of
4:08
more than 30 4.8 is included in the
4:17
That is the explanation regarding
4:20
protected forests and the criteria for determining them.
