Ergonomic Engineering Intervention Of Batik Stamping Work To Reduce Lifting Load

@#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.

Ergonomic Design Optimization for Train Seat Fit Parameters

This study is aimed at seat design optimization for high-speed train based on the Malaysians sitting anthropometrydata focusing on seat fit parameters. An analysis of anthropometry data composed of 15 dimensions that arerequired in seat design was done with 50 male subjects. These data were collected through direct measuringmethods with standard equipment. According to the Malaysian automotive seat fit parameters, the backrest width,backrest height, cushion width, and cushion length were established based on these anthropometric dimensions:interscye breadth (5th percentile female and 95th percentile male), hip breadth (95th percentile female), sittingshoulder height (5th percentile female), and buttock-popliteal length (5th percentile female), respectively. Thisstudy uses the CATIA software to design and analyse the proposed seat design. The fit parameters proposed for thenew design are seat height, 380mm; cushion width, 450mm; backrest width, 450mm and backrest height, 850mm.The CATIA human activity analysis (based on Rapid Upper Limb Analysis, RULA) was also executed. From the study,the new conceptual seat design gives the most optimized fit when compared to the current seat.
