Workload Assessment of Construction Workers Using the Job Strain Index (JSI) Method at Revitalization of Hospital X

Abstrak

Workers engaged in intensive physical and mental activities are at risk of experiencing an increased workload, which can lead to occupational health disorders. In the revitalization project at Hospital X, several workers reported discomfort in various parts of their bodies. A pre-assessment using the Nordic Body Map (NBM) questionnaire revealed that the most common complaints were in the right hand, back, and waist, with scores of 72, 70, and 69, respectively. These issues were primarily attributed to prolonged exposure to physical activity during the project's implementation. This study aims to identify musculoskeletal disorders through the NBM questionnaire and evaluate physical workload using the Job Strain Index (JSI) method for construction workers involved in various tasks, including piping, ducting, plumbing, electrical installation, and AC insulation. The JSI method indicated that ducting work had a score of 20.25, while AC insulation work received a score of 9, both exceeding the threshold for hazardous risk. Based on the hierarchy of risk control, recommended mitigation strategies include administrative interventions such as regulating work duration, scheduling rest periods, and implementing safety patrols. Additionally, there should be increased efforts to protect workers through the provision of complete, high-quality personal protective equipment (PPE), including helmets, masks, and gloves.
