One of the industries that support the fulfillment of food self-sufficiency is the rice milling industry. Rice milling activity cannot be separated from the working conditions. The working conditions in the rice mill at general pay less attention to the design aspects of ergonomics, occupational health and safety where employees work in standing, bent, and head down position, also lifting weights constantly. It causes fatigue and musculoskeletal disorders increases. This study aims to determine the improvement of working conditions may reduce fatigue and musculoskeletal disorders. The research uses experimental design Randomized Pretest and Posttest Control Group Design. The subject of research in the form of 30 male workers in the rice mill with an age range 16 until 56 years, divided into 15 subjects in the control group and 20 in the treatment group. The results showed that the post-test average the fatigue, there are results of 76.40 more less 13.50 in the control group and 55.53 more less 9.51 in the treatment group. Significance analysis showed that after two groups grind the rice, the fatigue average significantly different p less than 0.005. The amount of reduction in fatigue between the two groups was 27.31 percent. In the musculoskeletal disorders after the posttest showed that the mean score of musculoskeletal disorders in the control group was 77.33 more less 12.31 and the treatment group was 49.53 more less 8.18. Analysis of significance to the Independent Samples T Test after posttest showed that both groups average musculoskeletal disorders are different significantly, p less than 0.05. The amount of reduction in musculoskeletal disorders between the control group and the treatment group after the activity amounted to 35.95 percent. From this study we can conclude that the improvement of working conditions with the ergonomic approach may reduce the fatigue by 27.31 percent and musculoskeletal disorders by 35.95 percent.
