Abstract

This research aims to analyze the strength and results of welded joints by testing non-destructive and destructive tests using CO2 and argon shielding gases. The type of welding used was gas metal arc welding with SS400 steel material. After welding, the material was tested using liquid penetrant, porosity, tensile, and bending tests. The results were that CO2 shielding gas tended to have a convex and wide shape, while the welding results from argon gas tended to have a small and flat shape. In both shielding gases, there were defects in undercuts, lack of fusion, and spatter after the liquid penetrant test. The porosity test results have circular spots and irregular lines with holes. The average tensile strength value obtained from argon shielding gas was 255.761 MPa, and CO2 shielding gas produced an average value of 219.671 MPa. The bending strength of the material with argon shielding gas obtained an average value of 729.00 MPa and CO2 gas shielding an average value of 611.99 MPa.

Abstract

Desa Pondoknongko memiliki potensi besar dalam sektor perikanan, khususnya budidaya Kepiting Soka. Namun, keterbatasan pengetahuan dan teknologi dalam budidaya masih menjadi kendala bagi masyarakat setempat untuk meningkatkan produktivitas dan efisiensi panen. Kegiatan pengabdian masyarakat ini bertujuan untuk memberdayakan masyarakat Desa Pondoknongko melalui pelatihan budidaya Kepiting Soka dengan sistem apartemen dan penerapan teknologi Recirculating Aquaculture System (RAS). Metode yang digunakan meliputi sosialisasi, pelatihan praktik langsung, dan pendampingan teknis kepada para pembudidaya. Hasil kegiatan menunjukkan bahwa peserta pelatihan mengalami peningkatan pemahaman dan keterampilan dalam mengelola budidaya Kepiting Soka secara lebih efisien dan ramah lingkungan. Selain itu, penerapan sistem apartemen dan teknologi Recirculating Aquaculture System (RAS) terbukti mampu mengoptimalkan pertumbuhan Kepiting Soka serta mempercepat waktu panen. Kegiatan ini diharapkan dapat meningkatkan kesejahteraan masyarakat Desa Pondoknongko melalui pengembangan usaha budidaya Kepiting Soka yang lebih produktif dan berkelanjutan.
