Abstract

Kondisi yang dialami oleh masyarakat Desa Girimukti, Kabupaten Bandung Barat, adalah terbatasnya ketersediaan air bersih yang dekat dan mudah dijangkau oleh masyarakat. Sumber air bersih berada di atas bukit yang lokasinya cukup jauh. Fasilitas penampungan air yang ada saat ini, yaitu satu buah tangki dengan kapasitas 500 L, dirasa belum dapat memenuhi kebutuhan air bersih warga Desa Girimukti. Selain itu, kondisi air dari sumber mata air masih keruh sehingga belum siap pakai. Solusi yang dilakukan dalam program ini adalah penambahan saluran air dari mata air sampai penampungan, penambahan saringan air dari sumber mata air, serta penampungan air dengan kapasitas yang lebih besar di lokasi yang lebih terjangkau oleh warga. Metode yang dilakukan dalam program ini dimulai dengan survey kebutuhan masyarakat Girimukti, survey lokasi sumber air dan lokasi instalasi penampungan air, perencanaan dan desain purwarupa, instalasi purwarupa di lokasi, dan sosialisasi mengenai penggunaan dan perawatan fasilitas. Luaran dari program ini adalah saluran air yang mampu mengalirkan air dengan debit 0,1 liter per detik dan fasilitas penampungan air dengan kapasitas 5000 liter. Fasilitas penampungan air yang baru ini mampu memenuhi kebutuhan kurang lebih 60 KK penduduk Desa Girimukti yang terbagi dalam 3 RW. Masyarakat Desa Girimukti akan berperan serta dalam membangun saluran dari tempat penampungan air ke rumah-rumah warga.

Abstract

Tribocorrosion is a type of material degradation caused by simultaneous wear and corrosion of metal surfaces caused by laminar or turbulent flow. Additive manufacturing technology plays an important role in its application to precision components and complex assemblies. This study developed a 316LX material with Fe, Ni, Cr, and other powder alloys that was processed into an ultra-protective wire as a 3D printing filler. This simulation of tribocorrosion conditions was performed on a triboester machine. This simulation is expected to provide important insights and understanding into the behavior and properties of the 316LX 3D printing material, especially when exposed to abrasion and corrosion conditions in a sulfuric acid solution environment. Corrosion Rate Testing of 316LX Material Additives Using Potentiodynamic Methods in a Modified Rotating 5% Sulfuric Acid Fluid. In addition to corrosion rate, the Vickers hardness, metallography, and shrinkage of the 316LX green part material were also tested at 1000oC after sintering.

Abstract

Injection molding is a process by which plastic is heated until it softens to fill a closed mold and form a product. One of them is the benchtop injection molder, where the machine that was previously made at POLMAN had problems, namely the main frame structure and injection mechanism which was less sturdy during the injection process and the heating system which overheated. Based on these problems, a redesign and analysis was carried out on the existing benchtop injection molder machine. The design methodology used is VDI 2222, which is a technical concept design methodology suitable for product development. Heat Transfer Simulation on existing and latest designs using COMSOL Software with geometry, material, temperature, fluid inlet and outlet, and mesh parameters. The results obtained were uneven heat distribution to the middle of the existing barrel at a temperature of 4600K, while the new barrel had an even heat distribution to the middle at 4730K at the 10th second. The latest machine weighs 17.78 kg, dimensions 775 x 266 x 426 mm, barrel capacity 19 grams with an aluminum frame and tight band heater installation.

Abstract

POLMAN Bandung plaque is a thick product with a relief shape on the surface of the product. The product was originally made using sand casting technology, but now it needs to be developed using high-pressure die casting (HPDC) molding technology. This process was hampered by the absence of technical documentation, so development started from the available sand-casting products. This development was carried out in two stages, first product design, and second tool design. Based on the results of the research carried out, an optimal HPDC design has been produced according to the desired specifications. Product designs are obtained through 3D scanning technology to obtain appropriate geometric data. Then the data generated for mold design and the HPDC process includes a specific casting pressure of 400 bar; casting locking force of 1311 kN; piston diameter of 40 mm; 31.6% fill rate; piston movement (V(x)): first phase 0.497 ms-1 to 307 mm, second phase 2.08 ms-1 to 390 mm. The analysis process in the shot-sleeve simulation has produced the right data for the production process so that machine control is more precise, effective, and efficient.

Abstract

Permasalahan sampah masih menjadi isu yang terjadi di Desa Jagabaya. Sampah plastik sebelumnya hanya ditumpuk, dibakar atau dijual kepada pengumpul. Dalam rangka untuk meningkatkan daya jual sampah plastik dan mengurangi polusi lingkungan, dilakukan sistem pengolahan sampah plastik di Desa Jagabaya. Mesin pencacah plastik dibuat untuk membuat plastik menjadi cacahan kecil yang akan menjadi bahan pembuat eco paving. Kegiatan pengabdian dibagi menjadi beberapa tahap yaitu persiapan, perancangan, fabrikasi, validasi, sosialisasi, serta demonstrasi penggunaan mesin. Setelah dilakukan perancangan hingga proses validasi mesin, ditemukan bahwa mesin pencacah plastik dapat menghasilkan potongan plastik berukuran 5-8 mm. Mesin pencacah plastik tersebut kemudian di sosialisasikan kepada masyarakat untuk dapat digunakan. Masyarakat diberikan edukasi terkait cara pemakaian dan pemeliharaan mesin. Secara umum, masyarakat desa mendapatkan pemahaman tentang pemanfaatan plastik yang lebih luas. Selain itu, sampah plastik yang sudah diolah, dapat memberikan nilai jual yang lebih tinggi dibandingkan dijual mentah.

Abstract

Salah satu permasalahan kelompok tani di Desa Lebak Muncang, Ciwidey adalah konsumsi bahan bakar yang tinggi dan kebisingan berlebih pada mesin penggiling serta pencacah kulit padi yang menggunakan motor diesel. Kondisi ini tidak hanya berdampak pada tingginya biaya produksi, tetapi juga mengganggu peternakan itik yang berlokasi di sekitar area penggilingan. Sehingga produktivitas padi maupun itik tidak meningkat secara signifikan sesuai dengan target yang diinginkan oleh kelompok tani. Program pengabdian masyarakat ini bertujuan untuk memberikan solusi terhadap permasalahan teknis yang dihadapi oleh kelompok tani. Solusi yang diterapkan berupa modifikasi sistem tenaga penggerak dari motor diesel menjadi motor dinamo bertenaga listrik. Hasil implementasi menunjukkan penurunan signifikan dalam biaya operasional dari Rp 1.910.000 menjadi Rp 637.323,75 per bulan dengan efisiensi mencapai 33.34% serta pengurangan kebisingan yang berdampak positif pada produktivitas peternakan itik. Dengan demikian, modifikasi ini mampu meningkatkan efisiensi proses penggilingan padi sekaligus menjaga keberlanjutan lingkungan sekitar.

Abstract

Educational aids are very helpful in improving students' understanding of abstract subjects such as exact sciences. The Strength of Materials (SOM) course in the Manufacturing Design Engineering Department is supported by practical activities in the SOM studio using teaching aids, including truss bar tests. However, the currently used teaching aids have been complained about by students due to their complexity. Therefore, the development of a more user-friendly truss teaching aid prototype is needed. This article focuses on the evaluation of the impact of the developed teaching aid on its suitability for use in easier operations. The method used is observation techniques and interviews with students who have tried the previous teaching aids and the prototype being developed. The results showed that the prototype developed was better than the previous tool, because the procedure for using the tool was simpler and the duration of disassembling and assembling the test specimens was faster. Thus, it can be stated that the developed truss test teaching aid prototype is easier for students to use than the previous tool used in the SOM studio. Therefore, the development process and performance tracking of the developed prototype can be carried out at the next development stage.
