Abstract

To reduce risk factors for work-related musculoskeletal disorders (WMSDs) in the denture fabrication workforce, low-cost ergonomic interventions can be highly effective. This study aims to identify the risk of musculoskeletal disorders in the laboratory of PT X and reduce, enhancing worker comfort, productivity, and overall well-being. Using quantitative methods through RULA and REBA, as well as analysis of the ErgoFellow application, it was found that more than 50% of workers experienced musculoskeletal symptoms in the neck, shoulders, upper back, and wrists in the last 12 months. The Nordic Body Map questionnaire showed discomfort in most respondents due to their work. The results of the work posture analysis showed that the casting and sun-blasting workstations had a score of 4 with a moderate risk profile. In contrast, the night cooling workstation had the highest score of 6 with a moderate risk profile, indicating the need for further improvement. The night cooling station in particular requires investigation regarding the lowering of the stove position and adjustment of the pan position to reduce the risk to the arms and shoulders and improve safety. These recommendations are expected to improve working conditions and mitigate musculoskeletal risks at PT X.

Abstract

PT XYZ is a company engaged in the energy sector in Indonesia. Based on the company's 2020-2023 report, minor work accidents occurred with the highest frequency and increased in 2021 and 2022. Moderate work accidents increased in 2023 and serious work accidents increased in 2021. The number of work accidents that occurred from 2020 to 2023 in the company remained relatively high. This indicates that OHS management is a crucial concern, so that it can reduce the number of work accidents. Therefore, this study aims to measure the level of maturity of occupational safety culture (OHS) so that it can be used as evaluation material or recommendations for OHS management in the company. This study will consider psychological, behavioral, and situational aspects and use seven dimensions: commitment, information & communication, leadership, organizational learning, competence, involvement & engagement, and responsibility, as well as a quantitative approach through the Analytic Hierarchy Process (AHP) method. The results of the study indicate that the level of maturity of XYZ's safety culture is 4.48, so the company is at the proactive safety culture maturity level. The proposed improvement recommendations are to ensure that the condition of PPE and work safety equipment is functioning properly, create SOPs for each position, hold regular briefings before each job is carried out, conduct work area inspections, install warning signs and safety information in the work area, document all work that has been done, conduct work safety training according to each worker's job description periodically, and hold regular meetings about the importance of K3.
