Abstract

This study examines work postures of tempeh packaging workers using the Rapid Upper Limb Assessment (RULA) method. The aim was to identify postures that contribute to fatigue and potential musculoskeletal disorders (MSDs). Data were collected through observations and questionnaires, employing the Standard Nordic Questionnaire (SNQ) to assess discomfort levels in different body regions. The findings revealed that the work posture of tempeh packaging workers has a high ergonomic risk, with an average RULA score of 5. This score indicates that immediate corrective action is needed to prevent musculoskeletal injuries. The Nordic Body Map reveal that workers report substantial physical discomfort, particularly in the neck, back, shoulders, arms, and legs. The elevated scores of these complaints suggest a significant level of fatigue and a heightened risk of injury, necessitating targeted interventions. Unergonomic work postures, including bent positions, repetitive arm lifting and lack of postural variation during work activities, are major factors contributing to this high risk. Without intervention, these working conditions can lead to long-term musculoskeletal disorders in workers, which in turn will affect the productivity.
