Analysis of Posture Work in the Ship Hull Division in Makassar Shipping Industry: RULA and REBA Method Approach

Abstract

This research aimed to evaluate work posture values in the ship hull repair division of PT. ABC and to offer recommendations for improving less safe postures. Utilizing the REBA and RULA methods, the study conducted a quantitative analysis of worker postures in the cutting and welding sections. The REBA method identified a final score of 10 for cutting activities, indicating a high-risk posture that necessitates immediate corrective action. This score was derived from observations of neck, trunk, and leg postures during cutting, which revealed prolonged static positions. The RULA method, on the other hand, produced a final score of 6, denoting an action level 3, suggesting that changes should be implemented promptly to address observed issues. The analysis showed that both methods flagged the postures involving prolonged bending and twisting as high risk for musculoskeletal disorders (MSDs). These findings highlight a significant misalignment with ergonomic best practices, underscoring the urgent need for ergonomic interventions. To mitigate the risk of MSDs, the study recommends implementing regular posture breaks and establishing standard operating procedures (SOPs) for cutting and welding tasks at PT. ABC.
