Abstract

The development of electric vehicles in Indonesia requires the readiness of mechanics with specialized competencies in maintenance and repair. However, most motorcycle workshop mechanics in the Soloraya region still have limited knowledge and skills. This community service program aims to enhance the competence of mechanics through electric vehicle training and certification. The program was conducted at the Automotive Workshop of Politeknik Indonusa Surakarta in collaboration with Wuling Motor Indonesia, involving 20 participants from various motorcycle workshops. The training materials covered electric motor systems, batteries, battery management systems (BMS), and high-voltage occupational safety. The implementation methods included theoretical delivery, interactive discussions, and hands-on practice in electric vehicle maintenance and repair. The results indicated improved participants’ understanding, as shown by pre-test and post-test evaluations, and further reinforced by the awarding of competency certificates. This activity not only provided direct benefits for workshop mechanics but also supported the acceleration of battery-based electric vehicle implementation in line with government programs. Through this training, mechanics are expected to adapt to the development of automotive technology, enhance the competitiveness of local workshops, and contribute to sustainable transportation development in Indonesia.

Abstract

This research was conducted to determine the tensile stress of an object that was cut using a laser cutting machine. The purpose of this study is to determine the strength changes in the workpiece caused by cutting using laser cutting based on power and cutting speed. The workpiece used in this study is a polymer type Polymethylmethacrylate (PMMA) or better known as acrylic. This study uses variations in the amount of power and cutting speed, namely 50% power with a cutting speed of 5 mms, 50% power with a cutting speed of 10mms, 70% power with a cutting speed of 5 mms and 70% power with a cutting speed of 10 mms. From the results of tensile stress testing, the amount of power and speed of acrylic cutting affects the tensile stress of the workpiece. The greater the acrylic cutting power will reduce the tensile stress value of the workpiece by 11.4%. The faster the acrylic cutting will reduce the tensile stress value by 10.7%.

Abstract

Stress at work’ is a concept which there are lots of potential causes of stress in a working environment that can affect the productivity of a worker. Traffic congestion is a condition in transport that is characterised by slower speeds, longer trip times, and increased vehicular queueing. The experience of workers during traffic congestion before attending work could induce stress towards them, hence being assessed in this study. This study aims to assess the relationship between traffic congestion and work productivity. This study was conducted among a total sample of 133 individual workers in Kuala Lumpur which are prone to road traffic congestion in city areas. Raw data were collected in an online standardized survey. Data analysis was done using Microsoft Excel and SPSS using multiple hypotheses testing formula including ANOVA test, Linear Regression Analysis and Correlation Analysis. The findings of this study concluded that the data from all of the tests show consistent results which there is significant relationship between Stress at Work (p-value <0.05) and Road Traffic Congestion (p-value <0.05), but Work Productivity (p-value >0.05) shows insignificance towards the two variables. Therefore, it can be concluded that road traffic congestion causes stress to workers in Kuala Lumpur, but the stress induced from road traffic congestion does not hinder their productivity at work.

Abstract

Musculoskeletal Disorders (MSDs) are a prevalent condition that affects computer users with poor posture. Office workers are affected because they utilize computers to enter data, write letters, send emails, organize meetings, and communicate with coworkers and clients. Workers in the services sector use computers, phones, work documents, and stationery to communicate with consumers. To assess the level of discomfort for WRMSDs among desk job workers and the association with workstation design. 108 people took the online CMDQ, and 27 were chosen to assess the ROSA based on their scores. Upper back (13.9%), lower back (12.0%), and hip/buttocks (10.2%) reported the most discomfort. 26 (96.3%) participants were high-risk for ROSA and 3.7% were low risk. The result of the association showed that there was no association between the level of discomfort and workstation design. Each body part showed to have a p-value>0.05 associated with workstation design. Those with desk jobs in the telecommunication industry reported feeling the most discomfort in their upper back, lower back, and hip/buttock. The result of grand ROSA showed participants having a high risk of ROSA which required a further assessment. However, there was no significant association between the level of discomfort and workstation design. The finding of ROSA does not relate directly to the bad equipment in the workplace reported by the workers but rather to the improvement of worker’s posture, optimizing its use and findings can support the result of this study.
