Abstract

Occupational safety is a critical concern in automotive workshop environments due to the high-risk nature of tasks such as engine repair, welding, and electrical diagnostics. This study investigates automotive workshop risks at the Mitsubishi DIPO Workshop in Bukittinggi by identifying hazards, assessing risk levels, and formulating workplace accident prevention strategies. The HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method was applied to evaluate 28 potential hazards, two of which were classified as extreme risks. Further analysis of these risks was conducted using the Fishbone Diagram to identify root causes across six contributing factors: human, machine, material, method, environment, and management. Based on these findings, targeted risk control measures were developed following the hierarchy of control, including engineering interventions, administrative policies, and personal protective equipment. This research demonstrates how integrated methods such as HIRARC and Fishbone Diagram can support comprehensive occupational safety planning and risk mitigation in automotive workshops.

Abstract

This study investigates the mechanical performance of coconut coir fiber-reinforced composites with volume fractions of 30% and 40%, fabricated using the Manual Hand Lay-Up method. Specimens were tested under three-point bending following ASTM D790-03 to evaluate flexural strength. Results show that composites with a 30% fiber volume exhibit superior bending strength and stiffness compared to those with 40%, indicating a more optimal fiber–matrix ratio. The reduction in performance at higher fiber content is attributed to uneven resin distribution and inadequate fiber impregnation. These findings highlight the potential of coconut coir as a sustainable reinforcement material and emphasize the importance of optimizing fiber volume and manufacturing methods. The study recommends the use of alternative fabrication techniques, such as vacuum infusion, to improve resin homogeneity and mechanical reliability, particularly for structural and lightweight composite applications.

Abstract

. This study aimed to determine the effect of using a modified air filter set consisting of a stainless steel air filter and a slim filter box on the power, torque, and fuel consumption efficiency of a 2019 Honda Beat motorcycle. The study was motivated by the widespread use of aftermarket air filters that are claimed to improve engine performance and fuel efficiency; however, these claims have not been sufficiently supported by measurable experimental data.This research employed an experimental method using a Posttest-Only Control Design. Testing was conducted on a 2019 Honda Beat motorcycle using a chassis dynamometer to measure engine power and torque, while fuel consumption was measured using a burette at engine speeds ranging from 1,700 to 4,000 rpm over a 90-second testing period. The collected data were analyzed using mean calculations and percentage increases or decreases in the test results.The results showed that the modified air filter set increased the average engine power by 15.57%, with improvements of 6.17% at 6,000 rpm, 21.74% at 7,800 rpm, and 18.79% at 9,300 rpm. Engine torque also increased by an average of 15.50%, consisting of 6.34% at 6,000 rpm, 21.59% at 7,800 rpm, and 18.56% at 9,300 rpm. In addition, the modified air filter set reduced average fuel consumption by 5.48%, with the greatest reduction of 8.50% recorded at 4,000 rpm. Based on these findings, it can be concluded that the use of a modified air filter set, consisting of a stainless steel air filter and a slim filter box, has a positive effect on the performance of the 2019 Honda Beat motorcycle by increasing engine power and torque while improving fuel consumption efficiency.
