Abstract

This study aimed to evaluate the effect of disc diameter variation on friction moment, braking distance, and braking time on three-wheeled motorcycles for agricultural transportation. It involved testing three variations in disc size: 220, 260 and 300 mm, with three speed variations: 20, 30 and 40 km/h. The testing results revealed that the larger the disc diameter, the greater the friction moment. The 300 mm disc yielded the highest friction moment of 7246.1 N.m. The shortest braking distance (9.5 m) was achieved by the 300 mm disc at a speed of 20 km/h. For a speed level of 30 and 40 km/h, the braking distances were 18.20 and 27.2 m. Braking times also showed a similar pattern, where the 300 mm disc brake had the shortest braking time of 3.63 seconds at a speed of 20 km/h. At speed levels of 30 km/h and 40 km/h, braking times were 5.52 and 6.35 seconds. The test data showed that disc brakes with a larger diameter increased braking power by shortening the braking distance and time while increasing the friction moment, indicating that the disc brake size has a significant effect on the braking performance of three-wheeled motorcycles used for agricultural transportation the disc brake size has a significant effect on the braking performance of three-wheeled vehicle used for agricultural transportation.

Abstract

Campus waste management based on the principles of Reduce, Reuse, Recycle, Replace (4R) is a strategic approach to support carbon-neutral targets through the reduction of Greenhouse Gases (GHG). This study aims to estimate the GHG emission reduction potential of 4R activities in the academic community of Politeknik Negeri Jember. Questionnaire survey data from 309 respondents, divided by study program Automotive Engine, Renewable Energy, and Mechatronics Engineering, were categorised into 4R activities. The results showed that the participation contribution in the Recycle category was 82.5% and Replace 78.5%, Reduce 77.75% and Reuse 74%. Emission reduction estimation was conducted using the Life Cycle Assessment (LCA) approach based on IPCC emission factors, which takes into account the composition of organic waste, plastic, paper and residue. The LCA analysis showed that implementing the 4R has the potential to reduce emissions by 1.2tons of CO₂-eq per month, with the largest contribution from the activities of Reduce 360kg, Reuse 300kg, Recycle 300kg, and Replace 240kg. The findings indicate that participatory-based interventions and integration of the campus environmental curriculum play an important role in building a low-carbon ecosystem.

Abstract

This community service program focuses on empowering orphanage children by enhancing food self-sufficiency through the cultivation of vegetables using Modified Aeroponic Technology Based on Solar Energy (AT-BES). This initiative arose from several problems faced by the orphanage, including the limited availability of fresh vegetables and the deficiency in vegetable consumption among the children, which has resulted in cases of wasting (malnutrition and undernutrition). In addition, the orphanage has no land available for conventional farming. Until now, their vegetable needs have been met by storing small quantities in a refrigerator for weeks, causing the vegetables to wilt quickly and become unsuitable for consumption. Therefore, this community service program aims to address the challenges encountered by the Mambaul Ulum orphanage. The program began with an introductory socialization session, followed by the implementation of the Modified Aeroponic Technology Based on Solar Energy (including training and practical activities such as seedling preparation, training and production of POC as a substitute for AB Mix, equipment implementation, and the introduction of the garden-to-table concept), and concluded with an evaluation. The outcomes of the program demonstrated positive results, with participants achieving understanding levels of 83.2% for POC, 85.2% for seedling preparation, 82.9% for the AT-BES aeroponic system, and 85.5% for the garden-to-table concept. Furthermore, participant satisfaction with the program reached 86.5%. Their improved understanding of the cultivation process using the Modified Aeroponic Technology Based on Solar Energy (AT-BES) is expected to support food self-sufficiency and enhance agricultural skills.
