Abstract

Pengelolaan sampah di masyarakat semakin hari semakin meningkat dan menjadi permasalahan lingkungan hidup, misalnya saja pembuangan sampah. Pembuangan sampah sisa aktivitas sehari-hari masyarakat secara sembarangan akan merusak lingkungan sekitar, salah satunya adalah sampah plastik. Seperti halnya di wilayah Kota Pontianak, kapasitas penyimpanan sampahnya berkisar 348.150 liter per hari. Hal ini akan berdampak pada lingkungan sekitar kita. Untuk mengatasi masalah pencemaran sampah plastik, diciptakanlah mesin ekstruder plastik yang berguna untuk mengubah sampah plastik biasa menjadi filamen. Peneliti akan membuat mesin ekstruder plastik untuk mengolah sampah plastik menjadi bahan baku plastik yang siap diolah kembali menjadi bahan atau komponen yang diinginkan. Penelitian ini menggunakan metode eksperimen dengan merancang dan membangun mesin ekstruder plastik. Pembuatan mesin extruder plastik diawali dengan studi literatur, perencanaan mesin extruder, persiapan alat dan bahan, proses pembuatan rangka dan mesin extruder, pengujian mesin extruder, evaluasi hasil pengujian. Percobaan ini menggunakan plastik yaitu polietilen yang mempunyai rentang suhu 120 (℃) sampai dengan 150 (℃). Percobaan dilakukan pada beberapa variasi suhu mulai dari suhu 110 (℃), 115 (℃), 120 (℃), 125 (℃) dan 130 (℃). Dari kelima percobaan yang memberikan hasil baik adalah pada suhu 110 (℃) dan 115 (℃). Sedangkan pada percobaan hasil yang tidak baik terdapat pada suhu 120 (℃).Kata kunci: konversi energi, perancangan, manufaktur, pengolahan material, teknik mesin.

Abstract

Organic waste shredders are designed to speed up waste processing by chopping organic matter into smaller sizes, which in turn makes decomposition processes easier, such as composting or biogas production. The effective design of the shredding mechanism is essential for improving machine efficiency and ensuring optimal engine durability. Some factors that need to be considered in the design of an organic waste shredder include the type and characteristics of organic matter, the shredding mechanism used (such as knives, rollers, or hammer mills), motor power and rotation speed, feeding system, and the resistance of the machine's materials to wear. In addition, aspects of safety, user comfort, and noise and vibration reduction are also important elements in machine design. Choosing the right design based on these factors will allow the machine to operate efficiently, produce consistent shredding results, and accelerate the organic waste processing process, ultimately contributing to better and sustainable waste management.

Abstract

Plastic extruder machine is a machine that processes material changes from the form of plastic making into extruded changes from solid to liquid form. In the plastic extruder machine there are many machine components used. The components found in the plastic extruder machine are the frame, reduction gear, puller roller, bearing, v-belt, electric motor, pulley, stepper, clutch, air chamber, nozzle, feeder, compression spring, panel box and screw. This study uses an experimental method by changing the screw diameter which was originally 37 mm to 41 mm in addition to changing the diameter size, changes were also made to the screw pitch size which was originally 12 mm to 14 mm. The modified screw that was tested using PLA material with a rotation of 38 rpm produced a flow rate of 0.00129 m ^ 3 / s with a maximum pressure of 10.2866 Mpa. While the screw before modification produced a flow rate of 0.000921 m^ 3 / s and a maximum pressure of 9.5151 Mpa. From the data obtained from the screw, the modification results obtained quite good results compared to the screw before modification.

Abstract

A plastic extruder is a tool used with the extrusion process to change the shape of plastic shreds into filaments using high temperatures during the plastic melting process. The effect of temperature on the process of making filaments made from Polylactic Acid (PLA) using a plastic extruder machine and applying it to 3D printing. In making filaments, we usually use plastic pellets, including Polycaprolactone (PCL), Low Density Polyethylene (LDPE), and Polylactic Acid (PLA). Plastic pellets, especially PLA plastic pellets, have disadvantages, namely lower strength and durability, poor heat resistance, sensitivity to humidity, and post-process limitations. The purpose of making filaments is carried out with temperature variations of 110°C, 120°C, and 130°C to determine the optimal temperature that produces the best filament quality. in the printing process. The testing stages are literature study, determination of objects and pages, preparation of materials and machining, processes in making filaments (PLA), temperature settings, making 3D printing specimens, sample testing, and analysis. Conclusions to obtain optimal filament results are obtained through tensile testing. Before testing, the printing process was carried out using a 3D printing machine. After that, a tensile strength test was carried out to determine the mechanical strength of the filament produced. The results of this study showed that the extrusion temperature of 110°C is the optimal temperature for making PLA filaments using a plastic extruder machine. Filaments produced at this temperature have higher mechanical strength values and better surface quality.
