Abstract

Ergonomics is an approach that makes humans the main actors in the smooth running of the work system. PT. VRIZ is a company that produces stainless steel spoons. The manufacture of spoon products has 8 stages of the process with one employee working at any time and not allowed to stop before break time, the working hours that apply to this company are 7 working hours with 1 hour of rest. Static work has the potential to be easily bored, saturated and sleepy. This study aims to minimize the risky process flow taken in evaluating employee mental workload, analyzing the results of the two methods used, and providing recommendations for improvements in the workplace. With a better understanding of employee mental workload, PT. VRIZ can achieve higher levels of productivity and create a healthier and more sustainable work environment. The stages in this study use the RSME and KAUPK2 methods in data collection, this approach has a tool in the form of a questionnaire that must be filled out by the object or employee. The data obtained will be an early indication to provide improvements to the work system to reduce the impact of work fatigue. The Mental Effort Rating Scale questionnaire is one method of measuring mental workload by referring to the effort expended, while KAUPK2 is one method of measuring worker fatigue. The results of the Mental Effort Rating Scale show an average value of mental load of 115 (the effort expended is very large) and employee work fatigue using KAUPK2 shows the most dominant attributes felt by 8 employees, namely being reluctant to look others in the eye, being reluctant to work diligently and feeling tired all over the body.

Abstract

This study aims to evaluate the work system in the PT. Mulia Multi Medika warehouse using an integrative approach of Macroergonomic Analysis and Design (MEAD) and Macroergonomic Analysis of Structure (MAS). The method stages include: (1) identification of the environment and organizational structure; (2) definition of the work system through SWOT analysis; (3) setting performance expectations and mapping subsystems; (4) ergonomic risk assessment using the Workplace Ergonomic Risk Assessment (WERA) and Job Strain Index (JSI); and (5) analysis of the work environment in the form of temperature and noise. In addition, interviews with managers and workers were conducted to capture subjective perceptions of workload and system effectiveness. The results show that worker 1 has a WERA score of 41 (moderate risk) and a JSI of 18 (high), while worker 2 has a WERA score of 35 (moderate) and a JSI of 6.75 (low). The temperature of 18–22°C and noise of 68–72 dB are still within safe limits. The MEAD–MAS analysis revealed role imbalances and technological limitations. Recommendations for improvement include the use of material handling aids, role redistribution, and continuous evaluation to reduce ergonomic risks while increasing productivity.
