Abstract

Laboratories are essential spaces for conducting various experiments and research activities Occupational safety is the key to realizing work to achieve efficiency and productivity to provide benefits for companies in running a business. Through the use of the HIRARC (Hazard Identification, Risk Assessment, and Control) and ARC (Activity Relationship Chart) methods, this study intends to investigate how analysts perform analyses in the laboratory while adhering to occupational health and safety regulations and meeting productivity targets. Nine events were classified as high levels, four as low levels, six as extreme levels, and 19 as high levels after risks were identified and evaluated using the HIRARC method. The next step involved the author rearranging the analysis laboratory's instruments, specifically those for FFA (free fatty acids), water content, and contaminants, using the ARC method. This increased efficiency was first demonstrated by the following reduce in analysis time: FFA- 41%, water content - 25%, and impurities - 25%, secondly to reduce the distance traveled: namely FFA - 50%, water content - 17%, and impurities - 56%, and thirdly to reduce the total distance between lab instruments, namely FFA - 50%, water content - 6%, and impurities - 55%. Re-layout of laboratory instruments has reduced extreme risk and high-risk levels to low risk. It was concluded that there was an increase in the efficiency and productivity of analysts in carrying out every work process in the laboratory
