Brake lining technology is developing rapidly to adjust the absorption media in which the vehicle's braking system is operating. Material commonly used as a brake lining is asbestos and its alloys, but this material is very dangerous to the environment and health. This research was developed to overcome these problems, namely finding alternative brake lining pads material that has good mechanical and physical properties. Brake lining material is made from a hybrid composite reinforced basalt, shellfish, alumina, and phenolic resin (PR-51510i) as a binding matrix. This brake lining material is produced through a process of sintering at a temperature of 150 ° C with a load of 2000 kg for 30 minutes. These hybrid composites are made in as many as three variations, each of which is tested for olie absorption at several variations of immersion time. Immersion 3 days hardness of hybrid composite and asbestos brake lining material is still quite high between 24-28 HVN. The highest hardness at that time was an H1 specimen of 28.00 HVN. Then the hardness of the brake lining material decreases with the addition of immersion time and is close to stable at the

Manual materials handling has been identified as the most common cause of work-related musculoskeletal disorders. Among the manual material handling activities, lifting has long been regarded as an activity associated with a high risk of low-back pain. Lifting studies have mainly focused on the squat and stoop lifting techniques as an effort to improve the protection of workers from low back discomfort. However, neither is ideal and the benefits of one technique over another have proved inconclusive. The purpose of this study was to examine and compare the squat and stoop lifting techniques through analysis of muscles activation by using electromyography. Six volunteers participated in the study, and were required to lift a weight with squat and stoop techniques, with two types of loading at 1,7 kg and 6,7 kg. Observations were made on the rectus femoris, biceps femoris, and multifidus muscles. The results of study showed that the squat technique had higher levels of muscle activation compared to stoop technique on rectus femoris muscle. On the contrary, squat technique had lower muscle activation compared to stoop technique on biceps fermoris muscle. Meanwhile, both techniques squat and stoop had the same level of muscle activation on multifidus muscle. Conclusion, squat and stoop lifting techniques had the same opportunities to use.

The Pitik Jaya Women Farmers Group (KWT) is a business group located in Baluk village which is classified as a home business or home industry. This business group produces several types of products including; shredded eggs, flavored salted peanuts and others. In running its business, KWT faces a number of problems, especially for the production of the flavored salted peanuts. This problem is caused by the process of roasting peanuts using a rolling machine which is relatively simple with a limited capacity made from steel plates and is easily corroded and the spices are still stirred manually so it is uneven. Another problem is related to the high cost of LPG fuel used to heat the roaster. Based on this situation and to overcome these problems, the community service team designed and manufactured a roasting machine with biogas fuel. The field service activity (KWT Pitik Jaya) was carried out on August 22, 2021 in the form of an introduction and demonstration of a biogas-fired roasting machine. Next, on August 29, 2021, a safety demonstration was held and the official handover of the machine was attended by members of the Pitik Jaya KWT, the dedication team, Engineering students from the Udayana University Mechanical Engineering Study Program and Baluk village officials. The use of this biogas-fired roasting machine plays a very important role in increasing the production of flavored salted peanuts which reaches 320% or more than three times, as well as fuel cost efficiency reaching 90%, because it no longer uses LPG. Keywords : roasting machine, salted peanuts, biogas, increased production.
