Abstract

Kegiatan pengabdian kepada masyarakat ini dilakukan di UKM punjul jaya longcore di Desa Sempol, RT10/RW03, Kecamatan Sukoharjo, Kabupaten Wonosobo, Jawa Tengah dengan prioritas penyelesaian masalah produksi dan pemasaran produk kerajinan longcore. Metode dari kegiatan ini dilakukan menggunakan langkah-langkah, meliputi: observasi, konstruksi, sosialisasi, dan evaluasi. Hasil dari kegiatan pengabdian berupa penerapan teknologi tepat guna berupa oven biomasa untuk menyelesaikan masalah produksi dan melaksanakan pemasaran secara langsung untuk menyelesaikan masalah dalam pemasaran. Penerapan teknologi dan pemasaran langsung sepenuhnya dapat diaplikasikan dalam proses produksi kerajinan longcore. Berdasarkan hasil kegiatan pengabdian dapat disimpulkan bahwa peningkatan kapasitas produksi dapat tercapai dan pemasaran secara langsung dapat dilakukan dengan baik.

Abstract

Proses pengelasan Gas Metal Arc Welding (GMAW) merupakan metode yang banyak digunakan dalam industri pengelasan logam ferro dan non-ferro karena efisiensi waktu, kemudahan pengoperasian, dan biaya yang relatif terjangkau. Penelitian ini bertujuan untuk mengevaluasi pengaruh variasi arus pengelasan dan penambahan interlayer seng (Zn) terhadap sifat mekanik hasil pengelasan kampuh V pada baja karbon sedang ST37. Material penelitian berupa dua pelat baja ST37 berukuran 250 × 120 × 6 mm dengan celah kampuh 2 mm, serta lembaran interlayer Zn sepanjang 250 mm. Pengelasan dilakukan menggunakan arus 80 A, 100 A, dan 120 A. Hasil uji tarik menunjukkan bahwa kekuatan tarik tertinggi tanpa interlayer Zn dicapai pada arus 120 A sebesar 418,9 MPa, sedangkan dengan interlayer Zn mencapai 451,1 MPa pada arus yang sama. Pengujian kekerasan pada daerah Base Metal (BM), Heat Affected Zone (HAZ), Weld Metal 1 (WM1), dan Weld Metal 2 (WM2) menunjukkan nilai kekerasan tertinggi sebesar 166 HV pada WM2 tanpa Zn pada arus 120 A. Penambahan interlayer Zn terbukti meningkatkan kekuatan tarik sambungan las pada arus tertinggi, sedangkan kekerasan tertinggi tetap tercapai pada spesimen tanpa interlayer Zn

Abstract

Renewable energy is the cleanest source available on the planet. Water energy is one of the renewable energy sources that are widely available around us. Hydropower is energy obtained from flowing water or falling water. One of the utilization of hydropower by using a waterwheel. Since the 18th century waterwheels have been widely used both for grain milling, textile industry, and other uses. In the 20th century waterwheels began to be used for power generation. However, due to its low efficiency, the waterwheel began to be abandoned as a power plant. There have been many studies conducted to improve the performance of waterwheels, but the information is widely spread, so this article was made with the aim of collecting this information so that it can be known what parameters affect the performance of a waterwheel. The design of the right overshot waterwheel can achieve an efficiency of about 85%, the undershot waterwheel can reach 25% making these two wheels suitable for exploiting from varied and most frequently used flows. The performance of the waterwheel is made based on water discharge data, head differences, and how to use it so that it can be said that the waterwheel has different performance characteristics so that certain parameters are needed. Parameters that affect the performance of the waterwheel include the design of the blades, the amount of water collected on the overshot mill blades, the ratio of the sinking blades on the undershot waterwheel, and the angle used on the breastshot mill blades so that the waterwheel can work optimally to release the potential of water power with a low head.
