Abstract

This study aims to determine the variation of the depth of cut (DOC) on the surface roughness and serration gram (DOS) in the 6061 aluminum turning process using medium speed. In this study the infeed depths used were 0.5 mm, 1 mm, 1.5 mm, and 2 mm by testing the surface roughness using a roughness tester, and testing the teeth gram (DOS) using the SEM (Scaning Electron Microscope) tester. The value of surface roughness (surface roughness) in relation to the depth of cut (DOC) in 6061 aluminum material using a conventional lathe has increased, while the value of the dentition gram (DOS) to the depth of cut (DOC) in the aluminum 6061 lathe process at a depth of 0.5 mm figure shows the percentage of DOS 31.8 percent then continues to decrease with increasing depth of ingestion on the lathe. Based on the research results, the increase in the surface roughness value was due to heat generation which resulted in damage to the chisel resulting in high surface roughness. In addition, variations in the depth of cut gave a negative effect by showing a decrease in the number of serrations in grams, which made it difficult to break and would result in eye damage. chisel

Abstract

Partners in this service are MSME Duck Livestock, located in Junrejo, Batu. This partner currently uses conventional methods in carrying out the process of mixing animal feed. Therefore, the purpose of this service is to introduce and implement mechanization in the animal feed mixing process through the use of animal feed mixing machines. The animal feed mixer machine used has a capacity of 10 kg. The motor power used is 0.25 Horsepower (HP). The dimensions of this machine reach 740mm x 310mm x 550mm. This machine is equipped with four straight mixers used in mixing animal feed. Through the evaluation that has been carried out, the use of this animal feed mixing machine is proven to provide significant benefits. Mixing animal feed ingredients, which previously required quite a long time, has been shortened to only 3 minutes for every 10 kg of feed ingredients. This increase in efficiency is significant for MSME Duck Animal Feed. With the animal feed mixing machine, our partners can increase productivity and efficiency in their business. In addition, this machine also helps improve the consistency and quality of mixing feed, thereby positively impacting the growth and health of the ducks they care for. Overall, using animal feed mixing machines in this service has a significant positive impact on MSMEs of Duck Animal Feed. By increasing the productivity, efficiency, and quality of mixing animal feed, it is hoped that our partners can sustainably develop their businesses and increase their income.
