Abstract

This research was conducted to analyze the work posture of tofu factory operators using the Cornell Musculoskeletal Disease Questionnaire (CMDQ) and the Rapid Upper Limb Assessment (RULA) method for operators that work at a tofu factory in Banda Aceh, Indonesia. Data processing begins with direct interviews and closed questions to tofu factory workers toward the activity and posture disorders. From the results of the interview, a score was given based on the CMDQ answers to be integrated with RULA. Based on CMDQ, it can be seen that the operator feels uncomfortable in the upper limbs in sequence starting from the highest, namely the right shoulder (12%), right upper arm (12%), upper back (9%), left shoulder (8%), right and left forearms (8%). RULA measurements were carried out using the Ergofellow software with details of 1 process with a score of 3, 2 processes with a score of 5, 3 processes with a score of 6 and 7 processes with a score of 7. To reduce the critical position of body posture and to reduce the risk of injury to the operator, recommendations for improvement are given in the form of tools for work and determination of rest hours and work time according to standards.
