Work-related musculoskeletal disorders (WMSDs) are common risks, especially in jobs involving manual material handling in the manufacturing industry. Improper working posture can reduce worker performance and increase the risk of long-term injury. This study examines the risk of complaints in paper-shredding work using the Nordic Body Maps (NBM) method to evaluate complaints and the Rapid Entire Body Assessment (REBA) method to assess work posture. The purpose of this study was to identify the level of risk of complaints using NBM and evaluate the risk of work posture with REBA. This study uses a quantitative approach by collecting data through direct observation of paper-shredding activities and also additional data from literature and company documents. This study was conducted at PT XYZ from February 2024 until the completion of the thesis. The results of the NBM questionnaire showed that there were frequent complaints in the back, upper arms, waist, wrists, hands, ankles, and feet. A REBA score of 12 indicates a very high risk so that posture improvement is needed. Analysis using 3D SSPP showed that compression in the lumbar spine was approaching the safe limit, indicating the risk of back injury if this task is continued, and the high percentage of force in the shoulders and wrists indicated the potential for muscle fatigue and musculoskeletal injury.
