Abstract

. This is evidenced by the large use of steel in various machine components, work materials and building construction, both in the form of plates, sheets, pipes and so on. Damage that often occurs in the application of ST 41 steel is wear. Wear occurs due to the influence of external forces in the form of friction and is the most dominant factor in damage to the function of machinery. As a result, the service life and performance of various machine components are reduced and indirectly will increase maintenance costs. The public demand for this metal hardening technology is increasing, so researchers have tried to apply knowledge about metal hardening to knives with low carbon steel materials. Heat treatment aims to increase ductility.. This study shows that Heat Treatment with different temperatures and different cooling media can significantly affect the hardness of low carbon steel. The results of the study showed that the highest hardness of low carbon steel was obtained at a temperature of 950°C with oil cooling media, which was 44.30 HRC.

Abstract

Fisheries play a crucial role in the Indonesian economy, particularly for fishermen and coastal communities. However, fishery products such as fish floss have problems in the frying process, which requires continuous human power to stir. This research aims to design and develop a fish floss frying device powered by an electric motor with a driving power of 200 W. This tool is expected to facilitate the fish floss frying process, reduce the energy expended by the fish floss maker, and increase the efficiency of the production process. This research uses data collection methods, tool design, and tool testing. Autodesk Inventor software was used in the design stage to design the tool frame, stirrer, and pan holder. This tool includes an electric motor, gearbox, pulley, V-belt, and frying pan. Then, the tool was made using a hollow iron box, a stainless-steel pipe, and wood. This research yields a fish floss fryer equipped with an electric motor, capable of frying fish floss with a capacity of up to 3 kg. This tool can help ease the work of frying fish floss, save labour, and increase production efficiency. With a driving power of 200 W, this tool can produce good-quality fish floss
