Abstract
This research aimed to evaluate and reduce the ergonomic risk for lifting rubber sacks from the trucks at Maung Ubon Ratchathani rubber marketing cooperative. Subject of the study was 126 subjects.The results of the study showed that most of the farmers got pain around their lower back, upper back, lower arm, hand/wrist, shoulders, neck, calf, knees, foot and at 31.7% 15.1%, 11.9%, 11.9%, 9.5%, 7.9%, 7.9%, 2.4%, 1.6% respectively. The study examined the effectiveness of a newly designed work station for lifting rubber sacks from the trucks by using a forklift instead of manual material handling. For the device testing, 32 subjects were selected and tested and the effects from before and after using the work station were analyzed. The average Rapid Entire Body Assessment (REBA) score was 13.78 which place it as a high risk which dropped down to 5.06, a medium risk, after using the designed work station. The mean difference was 8.72 (95% CI = 8.39 to 9.05) and the p-value was 0.001. This means the risks were reduced significantly after the work station came into use. The results confirm ergonomically designed workstations can reduce the ergonomic risks of lifting the rubber sacks from the trucks at Maung Ubon Ratchathani rubber marketing cooperative.
