The Work Posture Evaluation at Assembly Work Station in MSEs of Silver Jewelry Handicraft with the REBA Method

Abstract

This research was conducted at MSEs of silver jewelry handicraft called SILVER 999. Workers in this MSEs, especially in assembly work station often experience back pain, neck pain, achy shoulders, achy hands called musculoskeletal disorders (MSDS). To reduce the risk of MSDS, ergonomic evaluation is carried out directly at this work station. Respondents in this study were all 10 workers. Data collection uses observation and filling in questionnaires. Worker posture is measured by Rapid Entire Body Assessment (REBA) method. The MSDS complaint was measured by filling out Nordic Body Map (NBM) sheets. The results obtained as much as 70% (7 people) work posture in the assembly section with a very high category and 70% (7 people) workers in this section who experience MSDS complaints with a moderate category. Non-ergonomic work postures can cause MSDS complaints. Work posture that is getting worse cause greater musculoskeletal complaints. This shows that the redesign of the assembly work station is recommended so that the work posture is more ergonomic and reduces the symptoms of MSDS.
