Abstract

The explosion of plastic-based waste (polymer) in the environment, as a result of its excessive use, so that this phenomenon causes damage to environmental ecosystems, water absorption is not optimal causes flooding, and polluting nutrients in the soil. Plastic is a polymer compound composed of the main elements, namely carbon and hydrogen. The best results in this study by using this tool have a physical appearance: yellow like premium fuel type "1.0" (color test results using the ASTM D1500 method), very pungent smelling liquid, thicker when compared to premium fuel types. And has specifications: Density value of 786.4 kg/m3, Sulfur Content 0.003% m/m, water content 282 ppm, CCI 53.4.

Abstract

Transformator tiang listrik, komponen penting dalam distribusi listrik, menghadapi risiko kebakaran yang signifikan akibat beban listrik yang tinggi, korsleting, dan faktor lingkungan. Pengembangan sistem proteksi kebakaran yang efektif untuk transformator ini sangat penting untuk mencegah pemadaman listrik dan meminimalkan bahaya kebakaran. Studi ini mengeksplorasi desain dan implementasi strategi proteksi kebakaran tingkat lanjut, termasuk penggunaan material tahan api, deteksi kebakaran otomatis, dan sistem pemadaman. Studi ini juga menekankan pentingnya perawatan rutin dan pemantauan waktu nyata untuk mengidentifikasi tanda-tanda awal panas berlebih atau kegagalan. Dengan mengintegrasikan sistem-sistem ini, risiko kebakaran transformator dapat dikurangi secara signifikan, sehingga memastikan keandalan dan keamanan yang lebih besar dalam jaringan distribusi listrik. Penelitian ini selanjutnya mengevaluasi dampak ekonomi dan lingkungan dari implementasi sistem tersebut, serta mendukung peningkatan standar keselamatan dalam infrastruktur utilitas

Abstract

This study analyzes the effect of the quenching process with various cooling media on the hardness of lead screw keys in a lathe. The objective was to determine the most effective cooling media for improving the key's mechanical properties, which play a critical role in the performance and durability of the lead screw. The cooling media tested included water, fresh SAE 10W-40 oil, and used SAE 10W-40 oil. The research method involved heat treatment at 850°C, followed by quenching using each medium, and then testing the hardness using the Rockwell B (HRB) method. The results revealed an unexpected finding: the untreated key had the highest hardness value (97.05 HRB), surpassing all quenched samples. Among the hardened samples, water produced the highest hardness (91.88 HRB), followed by used oil (82.32 HRB) and fresh oil (78.66 HRB). This indicates that the quenching process did not increase hardness and, in some cases, even decreased it. Potential causes include temperature instability during heat treatment and inaccurate material characterization, as SEM analysis failed to confirm the expected composition of the high-carbon steel. This study concluded that the quenching parameters and material characterization methods require refinement. Future research is recommended to utilize more precise temperature control, validate the material composition using techniques such as Optical Emission Spectroscopy (OES), and explore alternative cooling media. These findings emphasize the importance of precise heat treatment process control to achieve desired mechanical properties in industrial applications.

Abstract

Pelaksanaan Tridharma Perguruan Tinggi menuntut dosen untuk berperan aktif dalam kegiatanpengabdian kepada masyarakat (PKM) melalui kolaborasi dengan mahasiswa dan masyarakat.Kegiatan ini bertujuan untuk menjawab berbagai permasalahan yang dihadapi masyarakat,khususnya terkait peningkatan keterampilan dan perekonomian. Di Kota Palembang, jumlahpelaku UMKM pengrajin sepatu kulit sangat terbatas, tercatat hanya lima pengrajin yang masihaktif. Kondisi tersebut dipengaruhi oleh keterbatasan peralatan serta dukungan dalam aspekpemasaran. Dari sisi teknologi, pengrajin mengalami kesulitan dalam memperoleh akses terhadapperalatan modern karena kendala biaya, sehingga kapasitas produksi sangat rendah, yakni hanyasekitar dua pasang sepatu per hari. Jumlah ini jauh di bawah kebutuhan ketika ada undangan untukmengikuti pameran, yang biasanya membutuhkan 20–30 pasang produk. Melalui kegiatan PKMini, tim memberikan bantuan peralatan berupa mesin seset kulit, mesin post bed, shoe last berbagaiukuran, serta mesin press sepatu dengan harapan dapat meningkatkan kuantitas dan kualitasproduk yang dihasilkan. Selain itu, tim juga memberikan pelatihan teknik pemasaran berbasismedia sosial guna mendukung keberlanjutan usaha, sehingga peningkatan kapasitas produksidapat diimbangi dengan meningkatnya permintaan pasar.Kata kunci : Pengrajin Sepatu, Mesin Post bed , Mesin Seset kulit, Mesin pressSepatu, Pemasaran Digital
