Work Posture Analysis by Using Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA) Methods (Case Study: Rice Milling In Malang - East Java of Indonesia)

Abstract

Problems rising in the process of moving grain sacks in rice milling in Malang, there was a monotonous work activities and it was still handled without tools. In one day, the workers’ average of moving grain sack was 82 and the distance between the place of weighing and grinding was as far as 11 meters and the weight of the grain sacks moved was 40 kgs. To do working posture analysis to the rice miling workers, Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA) methods were used. The results of the observation and calculation of working posture by using RULA method on a stage of lifting sack obtained score 7 with high risk level, and on a stage of carrying sack obtained score 7 with high risk level. The results of the observation and calculation of working posture by using REBA method on a stage of lifting sack obtained score 8 with high risk level, and on a stage of carrying sack obtained score 10 with high risk level.
