Cara Membuat Celengan Dari Botol Plastik Bekas || Celengan Botol Bekas || Proyek P5 Daur Ulang

The creator greets viewers with assalamualaikum and introduces the project of making a celengan from a used plastic bottle. They remove the bottle cap, then cut off both the top and bottom rims, keeping only the cylindrical middle section. Double-sided tape is applied along the bottle surface, and a sheet of karton (cardboard) is wrapped around it, with excess material trimmed and edges folded inward. This section transforms a disposable bottle into a workable base for the piggy bank.

• The middle cylindrical section of a plastic bottle is the only part needed for the piggy bank body
• Double-sided tape is used as the primary adhesive for attaching cardboard to the plastic surface
• Trimming and folding cardboard edges inward creates a clean, finished look without visible raw edges

This section establishes the foundational structure; skipping it means missing the core transformation of a bottle into a craft base.

After the cardboard is wrapped around the bottle, the creator trims any overhanging karton and folds the remaining edges inside the bottle using double tape. Additional cardboard pieces are layered to reinforce the surface. The section focuses entirely on preparing the outer shell so that no plastic or rough cardboard edges are visible. The bottle now has a smooth, covered exterior ready for the end caps and decorations.

• Folding excess cardboard inward prevents frayed edges and gives the piggy bank a polished appearance
• Layering additional cardboard pieces reinforces the structure before end caps are attached
• The outer shell is fully prepared at this stage, with all visible plastic hidden beneath karton

The finishing quality of the outer shell determines whether the piggy bank looks like a craft project or a polished object.

The creator repurposes the bottle pieces cut off earlier, tracing and cutting circular shapes from them to serve as the top and bottom caps. One circle is marked with a straight line using a ruler, then carefully cut open with a cutter to form a narrow slot for inserting coins. The slot edges are cleaned up by following the drawn line precisely, producing a neat opening. This section solves the functional requirement of how money will actually enter the piggy bank.

• The bottle cutoffs are reused as material for the end caps, minimizing waste
• A drawn straight line guides the cutter to produce a clean, even coin slot
• One circle receives the slot while the other remains solid to seal the bottom

The coin slot is the functional heart of the piggy bank; this section is essential to making the bank usable.

The circular cardboard pieces are wrapped in additional karton paper and trimmed to size. One circle receives a slot cut along its marked line, matching the opening created in the previous section. Both circular end pieces are then attached to the top and bottom of the bottle body using candle wax (lem lilin) as the adhesive. The creator presses the pieces firmly into place, completing the basic piggy bank structure with a coin slot at the top and a sealed bottom.

• Candle wax (lem lilin) is used as the adhesive for attaching cardboard to cardboard
• The top circle must have a matching slot to align with the coin insertion opening
• The bottom circle remains solid to create a sealed base that holds coins

This section completes the structural assembly; without it, the piggy bank has no ends and cannot hold money.

With the structure complete, the creator shifts to decoration, using colored origami paper to cover the top and bottom areas of the piggy bank. A melted-liquid-shaped piece is attached to the top using a glue stick (lem stik), and a long strip of origami paper is wrapped around the bottom edge. The glue stick is chosen specifically for paper-to-paper adhesion, ensuring the decorative layers stay in place without damaging the origami.

• Origami paper is used for decoration because it is thin, colorful, and easy to fold into shapes
• A glue stick is the recommended adhesive for paper-to-paper attachment, avoiding moisture damage
• The top decoration includes a melted-liquid shape while the bottom gets a wrapped strip

This section transforms the functional structure into a visually appealing craft; skipping it would leave the piggy bank looking like bare cardboard.

The creator attaches cut-out eyes and a mouth made from paper to the piggy bank body, transforming the plain cylindrical structure into a recognizable pig character. The facial features are positioned carefully to give the piggy bank a friendly, expressive appearance. This section personalizes the craft and gives it its identity as a celengan (piggy bank).

• Paper cut-outs for eyes and mouth are the simplest way to give the piggy bank character
• The placement of facial features determines whether the pig looks friendly or neutral
• This step completes the pig identity that justifies the name celengan

Without facial features, the craft is just a decorated cylinder; the eyes and mouth make it a piggy bank.

The creator designs a savings goal display by cutting cloud shapes from HVS paper and layering colored origami paper on top, with the excess paper trimmed to extend beyond the white cloud outline. A specific savings target such as membeli sepatu (buying shoes) is written on the display. Ice cream sticks are cut to adjustable sizes and attached to the back of the goal text as stands, then the entire display is mounted on the piggy bank. This section adds a motivational element, turning the piggy bank into a visual savings tracker.

• Cloud shapes cut from HVS paper serve as the display background for the savings goal
• Colored origami paper layered on top of white clouds creates a visually striking contrast
• Ice cream sticks cut to size function as adjustable stands that hold the goal text upright
• The goal text should be specific (e.g., buying shoes) to make the savings target tangible and motivating

The goal display is what elevates this from a simple piggy bank to a motivational savings tool; it is the most distinctive feature of the project.

The creator holds up the finished piggy bank and demonstrates how to insert money through the top slot, confirming the mechanism works easily. Closing remarks include the phrase Selamat mencoba dan semoga bermanfaat and a goodbye greeting of wasalamualaikum. The video ends with the creator thanking viewers for watching. This section confirms the project is complete and functional.

• The finished piggy bank accepts coins through the top slot without obstruction
• The creator confirms the entire process is simple enough for anyone to replicate
• The closing thanks reinforces the project as a shareable, community-oriented craft

The demonstration confirms functionality and the closing provides a natural endpoint, but the core craft is already complete by the previous section.
