Abstract

This project has been conducted in CTRM Aero Composites Sdn. Bhd. located in Batu Berendam. According to research observation, interview and distributing questionnaires, the problem statement was focused on low back pain occurred when workers work with awkward postures and the impact on workers productivity. Therefore the aims for this project were determined the ergonomic design problems in workstations, analyze the body posture and worker productivity and suggest the best ergonomic design solutions to improve the body posture and worker productivity. In order to analyze the body postures, the anthropometry measurement, workstation measurement, work measurement and labor productivity is collected. The CATIA V5 is used for RULA analysis before and after improvement. The new suggestion on ergonomic design is to reduce the bad postures. The labor productivity is calculated before and after the improvement made to compare and validate the improvement of workers postures toward worker productivity. All the results from the analysis are compared after the bad postures are reduced. The scope was focused on the postures due to prolonged standing and sitting that affects the low back pain. The project is limited because there will no fabrication and the improvement of workers postures only by CATIA V5 to validate the effectiveness of the new postures. The expected results from the survey questionnaire we capable to identify the ergonomic design problem in workstation, able to find out the reasons behind the body posture and its effect on the worker productivity and reduce the problems by suggesting the suitable ergonomic design that will increase the worker productivity. As recommendation, this research could be further investigated through the implementation of proper tools to reduce low back pain problems in workers.
