Analisis Risiko K3 Menggunakan Metode IBPPRP dan JSA pada Proyek Pembangunan Pengendalian Banjir Air Bengkulu

Abstract

The construction of the Bengkulu Flood Control Project represents an activity that poses significant risks to Occupational Health and Safety (OHS), primarily due to the complexity of work stages and the continuously changing working environment. Various construction activities—such as excavation works, operations in wet areas, the use of heavy equipment, steel structure installation, and working at heights exceeding six meters, particularly in pump house construction—significantly contribute to the escalation of on-site hazards. If not managed systematically, these conditions may lead to workplace accidents. This study is designed to systematically identify potential hazards, evaluate the level of risk, and develop appropriate control strategies using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) and Job Safety Analysis (JSA A descriptive quantitative approach was utilized, involving 25 respondents from both project management and field workers. The findings reveal 49 risk variables across seven major work categories, covering risk categories from low up to extreme. The highest risks were identified in wall and roofing works, particularly associated with falls from height, falling materials, lifting equipment failure, and electrical hazards. Control actions were applied following the hierarchy of controls, covering elimination, substitution, engineering interventions, administrative arrangements, and personal protective equipment (PPE), further reinforced through safety communication practices such as safety briefings and toolbox meetings. The implementation of HIRADC and JSA significantly enhances hazard identification and risk control processes, thereby supporting the creation of a safer working environment and improving overall construction project performance.
