Project X is classified as a high-risk project. The sources of accidents that may occur can be attributed to two factors: unsafe conditions and unsafe behaviors. Potential hazards include falling from heights, being struck by formwork materials, being hit by scaffolding materials, being hit by iron, and skin irritation. Project X has implemented the Occupational Safety and Health Management System (SMKK) in accordance with Regulation of the Ministry of Public Works and Public Housing Number 10 of 2021, which includes the Construction Safety Plan document known as IBPRP.This research aims to identify the risk factors that may lead to accidents on Project X, particularly focusing on reinforced concrete work, and to examine the control measures implemented. Data collection involves observation to identify hazards and their controls. Subsequently, a questionnaire related to hazards and risk controls is developed, and project documents are reviewed. Statistical tests and document studies based on IBPRP and the project's Job Safety Analysis (JSA) are conducted for analysis.Based on the F-test, it is found that factors contributing to accidents in reinforced concrete work include human factors, materials, equipment, environment, and work methods. The implementation of construction safety risk controls for reinforced concrete work on Project X is considered good, with a safety risk control implementation rate of 85%. However, it is noted that not all risk control measures outlined in IBPRP and JSA for reinforced concrete work have been fully applied in the field.
