Abstract

Penelitian ini menganalisis pengaruh torsi terhadap RPM pada dinamo listrik 1 HP yang digunakan dalam mesin pencacah rumput gajah. Rumput gajah, dengan kadar air tinggi mencapai 66,6%, terbukti memberi beban signifikan terhadap kinerja dinamo. Pengujian dilakukan pada dua tipe mesin pencacah (Mesin A dan B) dengan beban ±1 kg per sesi. Hasil eksperimen menunjukkan bahwa penurunan RPM akibat beban pada Mesin A mencapai hingga 87% (dari 2890 menjadi 338,6 RPM), sementara Mesin B mengalami penurunan yang lebih terkontrol dengan fluktuasi stabil di bawah 80%. Penurunan RPM dikaitkan dengan tersumbatnya cacahan di mata pisau, serta ketidakseimbangan ukuran lubang filter. Grafik penurunan RPM memperkuat bahwa torsi meningkat seiring tingginya kadar air dan beban material. Perhitungan teknis pada sistem penggerak menunjukkan kecepatan keliling pulley mencapai 23,08 m/s dan gaya keliling v-belt sebesar 93,84 N. Data perawatan dan pengaturan beban juga disajikan sebagai rekomendasi berbasis bukti untuk menjaga efisiensi putaran dinamo. Temuan ini menjadi dasar untuk pengembangan mesin pencacah yang lebih tahan terhadap variasi material organik basah.

Abstract

This study aims to analyze the effect of blade edge angle geometry on the particle size distribution and quality of shredded materials, ranging from plastic to cardboard, using a rotary cutter–type shredding machine. The blade edge angles investigated in this study were 35° and 60°, with test materials consisting of polyethylene terephthalate (PET) plastic, plastic bags, and cardboard. Operating parameters of the machine, including rotational speed, number of blades, and blade thickness, were kept constant throughout the experiments. The analysis focused on shredding capacity, particle size distribution, and the quality of shredded products in terms of shape uniformity and process stability. The results indicate that the 35° blade angle produces higher shredding capacity, smaller and more uniform particle sizes, and better overall shredding quality compared to the 60° blade angle. In contrast, the 60° blade angle tends to produce longer and less uniform particles, particularly for flexible plastic materials, and increases the likelihood of material clogging during the shredding process. Based on these findings, it can be concluded that a blade edge angle of 35° is the optimal configuration for achieving efficient shredding performance and high-quality plastic output, thereby supporting recycling processes.

Abstract

This study investigates the relationship between microstructural changes and mechanical properties in an edge joint of ST 37 steel following Shielded Metal Arc Welding (SMAW) at 100 A using an E6013 electrode, without subsequent heat treatment. The analysis focuses on the Weld metal, Heat Affected Zone (HAZ), and Base metal through metallographic examination and Vickers hardness testing. The results indicate that variations in hardness values are strongly influenced by microstructural transformations induced by the thermal cycle during welding. The HAZ exhibits the highest hardness (172 HV), which correlates with an increase in the pearlite fraction to approximately 60% because of a relatively rapid cooling rate. This phase transformation leads to a harder microstructure, although it tends to be more brittle compared to the other regions. Meanwhile, Weld-metal records a hardness of 157 HV, and the Base metal shows 142 HV, reflecting differences in composition and thermal history across each zone. Overall, the average joint hardness of 157.33 HV demonstrates that despite significant microstructural modifications, the mechanical integrity of the welded joint remains acceptable and meets relevant standards.

Abstract

This study aims to analyze the effect of variations in the rotational speed of an electric motor on shredding capacity and the average size of shredded output in a plastic waste shredding machine. The method used is an experimental approach by conducting direct tests on a shredding machine using a single-phase electric motor with a power of 2 HP, with speed variations of 600 rpm, 900 rpm, and 1200 rpm. The test materials include plastic bottles, plastic bags, and cardboard, with a shredding time of 2 minutes for each test. The observed parameters include the mass of shredded material, shredding capacity (kg/h), and the average size of the shredded output. The results show that the highest shredding capacity for plastic bottles and plastic bags was achieved at a speed of 900 rpm, reaching 25.20 kg/h and 13.50 kg/h, respectively, while for cardboard material, the highest capacity was obtained at 600 rpm, reaching 28.59 kg/h. These findings indicate that increasing rotational speed does not always result in the highest shredding capacity for all materials, as the physical characteristics of the materials influence the shredding performance.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Makarti, Kabupaten Kutai Kartanegara, dengan tujuan untuk meningkatkan produktivitas budidaya ikan nila melalui penerapan teknologi tepat guna dan pemberdayaan masyarakat. Permasalahan utama yang dihadapi masyarakat adalah keterbatasan dalam mengelola kualitas air kolam serta kurangnya sarana pendukung budidaya. Untuk menjawab permasalahan tersebut, tim pengabdian merancang dan menerapkan sistem aerator berbasis Internet of Things (IoT) yang dilengkapi dengan sensor suhu dan pH, guna memantau kondisi air secara real-time. Selain itu, dilakukan pelepasan 1.500 ekor bibit ikan nila ke kolam warga sebagai bentuk dukungan nyata terhadap keberlanjutan budidaya. Hasil kegiatan menunjukkan bahwa suhu dan pH air kolam berada dalam kisaran optimal untuk pertumbuhan ikan nila, dan penggunaan teknologi monitoring berbasis IoT memberikan kemudahan bagi warga dalam melakukan kontrol kualitas air.
