Posture Analysis Using the Rapid Entire Body Assessment (REBA) & Nordic Body Map (NBM) Methods to Reduce the Risk of Musculoskeletal Disorders (MSDs) in Automotive Company

Abstract

This study aims to identify the operator's posture at work, determine the factors that influence the occurrence of musculoskeletal disorders (MSDs) complaints, and give suggestions for improving the postures. The method used in the research is Nordic Body Map (NBM) and Rapid Entire Body Assessment (REBA). Material handling processes carried out by some operator's production in the line press magazine stamping could be affected body postures. If the company does not carry out an analysis of the situation, it could be impacting the risk of Musculoskeletal Disorders for the operator who is working in this area. Process manual handling was carried out 4800 cycles in a day (8 hours of work) with a bent posture, causing complaints of musculoskeletal disorders (MSDs). The results of Nordic Body Map (NBM) questionnaire processing results scored 75 and 81 points, and the second activity was the REBA assessment when the operator took material from the train. The REBA score was 8. The results of this study have high scores for NBMs and REBAs, requiring investigation and changing work attitudes.
