Occupational accidents remain a major issue in the informal industrial sector, particularly in welding workshops where workers are exposed to various occupational hazards. Data from BPJS Employment, Jayapura Branch, reported an increase in occupational accident cases in Jayapura Regency from 288 cases in 2019 to 329 cases in 2020. This study aimed to analyze factors associated with occupational accidents among welding workers in Waibu District, Jayapura Regency. This study used an analytic observational design with a cross-sectional approach. The research was conducted in eight welding workshops in Waibu District, involving 36 welding workers selected through total sampling. Data were collected using a structured questionnaire. The independent variables included age, education level, knowledge, and length of employment, while the dependent variable was the occurrence of occupational accidents. Data were analyzed using univariate and bivariate analyses with the Chi-square test. The results showed that among the 36 respondents, 50.0% were aged ≥35 years, 66.7% had a low educational level (elementary to junior high school), 50.0% had poor knowledge, and 66.7% had worked for less than five years. Bivariate analysis revealed no significant association between age (p = 0.469) and length of employment (p = 0.124) with occupational accidents. However, education level (p = 0.020) and knowledge (p = 0.030) were significantly associated with occupational accidents among welding workers. In conclusion, education level and occupational safety knowledge were significantly associated with occupational accidents among welding workers in Waibu District, while age and length of employment were not associated. Improving workers’ knowledge through occupational safety and health education and training is recommended to reduce the risk of workplace accidents.
