Risk Assessment Of Working Posture And Implementation Of New Workstation To Increase Productivity

Abstract

In the production process of plastic spoons, workers who run the separation process are working in a less ergonomic condition. In consequence, the production process lacks productivity because the task requires relatively longer time than it should. Utilizing Nordic Body Map analysis method, this study found that there are physical complaints among workers. More specifically, using Quick Exposure Score method, the exposure score on the separation station is at 59.09% and at 67.90% on the packaging station. Using REBA method of analysis, this research obtains REBA score at 10 on the separation station and 9 on the packaging station. Using WERA method, the last score on the separation station is at 40 and the packaging station at 33. The standard time based on the current workstations is at 127.97 seconds. Improvement is manifested by designing working tools. The implementation of the new tool results in the decrease of biomechanical complaints and exposure level at 49.38%, REBA score at 3, and WERA score at 26 on the separation, arrangement, and counting process. This research also results in WERA score at 25 during the process of inserting packing output. The total of standard time is reduced up to 62.10%.
