Effect of OSH Supervision on Safe Work Behavior of Construction Workers, Ponorogo Indonesia, 2025

Abstract

Unsafe behavior is a major contributor to occupational accidents in construction projects. In Ponorogo, local reports documented 18 construction accidents in early 2024, with most caused by unsafe acts. Effective Occupational Safety and Health (OSH) supervision is essential to ensure compliance with safety standards and reduce unsafe practices. This study aimed to determine the effect of OSH supervision on safe work behavior among construction workers in Ponorogo, Indonesia, 2025. A quantitative cross-sectional design was applied involving 42 construction workers recruited through simple random sampling, with inclusion criteria of at least one month of active employment. Data were collected using structured questionnaires and direct observations. Variables studied were OSH supervision (low, high) and safe work behavior (unsafe, safe). Associations were analyzed using the Chi-square test and prevalence ratio (PR) with 95% confidence intervals. Results showed that 71.4% reported high supervision, and 69.0% demonstrated safe behavior. Workers with high supervision were significantly more likely to behave safely (p = 0.000; PR = 19.50; 95% CI: 3.642–104.411). In conclusion, OSH supervision strongly influences safe work behavior. Strengthening consistent monitoring, corrective actions, and enforcement mechanisms is recommended to improve compliance and guide policy in construction safety management.
