Abstract

Fatigue failure is the most common failure in gears besides failure due to friction and wear on the surface of the gear. To determine the failure phenomenon that occurs in gears, testing can be done on the gear, but the testing will be expensive. So it is necessary to test on a laboratory scale to understand the failure mechanism of gears by designing and making a twin-disk friction torque test rig. The design process used an approach model developed by the National Aeronautics and Space Administration (NASA) to maximize user desires with the Quality Function Deployment (QFD) method approach and to be able to meet technical needs with the Function Analysis Methods (FAM) approach. The results of the design that has been done provide the design of a twin-disk friction torque test rig that has met user needs and, from the test results of the test rig's performance, has met the expected functional requirements as a test tool. From the results of tests that have been carried out on changes in load and slip ratio, the friction torque will increase with increasing load and slip ratio. While the friction coefficient will decrease with increasing load, and vice versa, with increasing slip ratio, the friction coefficient will increase. The data generated from the measurements are consistent, so the test rig can be used to measure friction torque.

Abstract

Spices have long been an integral part of human life, playing a vital role as traditional medicine, culinary ingredients, and components in cosmetics. Indonesia, particularly within the Southeast Asian region, is regarded as a global hub for high-quality spices. One such spice-rich area is Nagari Koto Anau, located in Solok Regency, known for its production of cloves and cinnamon. However, this significant potential has yet to be fully harnessed by local farmers due to limited processing technology—particularly the lack of spice grinding machines. As a result, farmers are only able to sell their spices in raw form at low market value, which adversely affects their income. To address this issue, the design and implementation of a spice grinding machine that can be operated directly by farmers is essential. The aim of this activity is to accelerate the spice processing workflow, improve work efficiency, and enhance the added value of spice products at the local level. The programme was carried out in Nagari Koto Anau, Solok Regency, West Sumatra Province. The methods employed included interviews, equipment design, and training on the use of the spice grinding machine. Interviews involved discussions with farmers to identify their problems and offer practical solutions, followed by designing the machine based on their specific needs. The training method included a hands-on demonstration on how to operate the spice grinder. The results showed that the spices processed using the grinder became fine and evenly ground, with a production output of up to 20 kilograms.
