Kajian Risiko Potensial Kecelakaan Kerja Menggunakan Metode Hirarc Pada Proyek Pembangunan Apartemen Sky House Alam Sutera Phase 3

Abstract

High-rise building projects involve substantial occupational accident risks due to work at height, material handling, mechanical equipment, and hot work. This study aims to identify hazards, assess risk levels, and evaluate risk controls on the Sky House Alam Sutera Phase 3 Apartment Construction Project using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. A quantitative descriptive case-study design was applied. Data were collected through field observations and a review of safety documents, particularly Permit to Work (PTW) records and HSE reports. Eight critical hazards were assessed based on likelihood and severity. The findings show that six hazards were classified as medium risk and two as low risk before strengthened controls. The dominant hazards were falls from height, falling objects, hot-work fire, and lifting failure. Engineering controls, PTW, routine inspections, HSE supervision, and personal protective equipment reduced most residual risks to the low category. PTW compliance reached 100%, while PPE compliance was approximately 90%. HIRARC provides an effective basis for prioritizing controls, although worker behavior remains a residual risk that requires continuous supervision and safety-culture reinforcement.
