dc.description.abstract | Firefighters have a high risk of occupational fatalities due to the dangerous situations and stresses they face. Factors that cause occupational stress include exposure to repetitive trauma, hazardous work environments, high job demands, workload, time demands, and conflict in the workplace. In Dairi Regency, there were 99 fire cases in 2020, 107 cases in 2021, and 146 cases in 2022. This study aims to understand the factors that cause job stress in firefighters at the UPT Dairi Fire Department with a cross-sectional quantitative approach. The research location was UPT Firefighters of Dairi Regency with a population of 82 people and a sample of 73 people based on inclusion and exclusion criteria. Data were collected through questionnaires, observation, and secondary data. Measurement of work stress variables using the Perceived Stress Scale (PSS) and work environment variables, workload, time demands, and conflict using the Fuzzy Delphi Method (FDM). Data analysis used multiple linear analysis. The results showed 53.4% of officers experienced mild work stress and 28.8% severe work stress. The correlation of the coefficient of determination shows the effect of the independent variable on the dependent is 43.1%. Linear regression analysis showed workload had a significant effect on work stress (p value 0.003 <0.05), while other factors did not. To reduce stress, suggested measures include increasing the number of employees, providing clear job descriptions, fair work shift rotations, and providing adequate facilities and management support | en_US |
