<![CDATA[Background: The electricity industry is a high-risk work sector because it involves activities at heights, handling energized electrical installations, and demanding high levels of concentration and alertness. Poor sleep quality and occupational fatigue may reduce alertness, slow reaction time, and increase the likelihood of work-related errors that may contribute to occupational accidents. Purpose: To analyze the relationships between sleep quality and occupational fatigue and the potential risk of occupational accidents among Technical TAD (Outsourced Personnel) partner workers at PLN X in 2026. Method: This quantitative study employed an analytical observational design with a cross-sectional approach. The study population consisted of 35 Technical TAD partner workers, all of whom were included as the study sample using total sampling. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), occupational fatigue was measured using a fatigue questionnaire, and potential occupational accident risk was assessed based on unsafe conditions, unsafe actions, and near-miss events. Data were analyzed using the Chi-Square test and Odds Ratio (OR), with a significance level of α=0.05. Results: A total of 21 respondents (60.0%) had poor sleep quality, 18 (51.4%) experienced high levels of occupational fatigue, and 20 (57.1%) had a high potential risk of occupational accidents. Significant associations were found between sleep quality and potential occupational accident risk (p=0.036; OR=4.500) and between occupational fatigue and potential occupational accident risk (p=0.011; OR=6.417). Respondents with poor sleep quality had 4.5 times higher odds of having a high potential risk of occupational accidents, while those with high occupational fatigue had 6.417 times higher odds. Conclusion: Sleep quality and occupational fatigue were significantly associated with the potential risk of occupational accidents among Technical TAD partner workers at PLN X in 2026. The company is encouraged to strengthen monitoring of workers' physical condition and readiness before assigning them to high-risk tasks and to provide education on fatigue management and maintaining adequate sleep quality.]]>
