Abstract

Human resources are the main elements that influence the process of adding product quality. The main role of the workforce is still the main thing in the industrial world, not a few companies still require manual handling. After observing and interviewing on the production floor for all work stations, there were findings of problems, namely 7 workers experienced pain/complaints due to work. One of the efforts to overcome the problems that occur is to evaluate the posture of the workers at all work stations using the Rapid Upper Limb Assessment (RULA) method, and statistical tests are carried out to determine the relationship between work posture variables and musculoskeletal complaints. The statistical test results show the correlation coefficient (r) of 0.695 while the table value of 0.514. The output significance value shows a value of 0.004 which means <0.05, it can be said that there is a relationship between work posture and musculoskeletal complaints or in other words, the higher the work posture value, the higher the musculoskeletal complaints in workers. While the results of the chi-square test > table value (8,750>5,991) showed the asymp value. sig, obtained p value of 0.013. Because the value is 0.013 <0.05, it can be concluded that Ho is rejected and Ha is accepted, which means that there is a significant relationship between work posture and musculoskeletal complaints. Based on the results of the research, it is suggested that workers should pay attention to their posture during work, the company should provide training and guidance on ergonomic positions during work, and the last one is to design tools according to the needs on the production floor. The design of the tool in the form of an ergonomic chair is in accordance with the anthropometric data of the workers.
