Ergonomic engineering intervention of batik stamping work to reduce lifting load

Abstract

One of the common health problems for small and medium enterprise such as batik production is work-related musculoskeletal disorder (WMSD). This health problem may contribute to long-term medical effect on the production workers. For batik stamping workers, the load of the copper block that need to be used repetitively can reach up to 2kg. This study aims to reduce WMSD effect by reducing the lifting load of the cooper block handled by the batik stamping worker. The worker's working load is observed before the intervention process by using one of the ergonomic risk assessment tools, Rapid Upper Limb Asssessment (RULA). The ergonomic intervention designed in this study is from the engineering approach by modifying tools. It is found out that the intervention done were able to eliminate the lifting load handled by the worker to avoid discomfort or further health complication. This outcome are hoped to be able to improve workers' health and increase batik stamping work productivity that eventually increased company's revenue.
