IDENTIFIKASI DAN PENILAIAN RISIKO KECELAKAAN KERJA MENGGUNAKAN METODE JSA DAN HIRARC PADA PROYEK PEMBANGUNAN GEDUNG

Abstract

Multi-storey building construction involves many activities that can lead to workplace accidents, yet Indonesian HIRARC and JSA studies generally stop at hazard lists and generic recommendations without analysing risk distribution patterns or control priorities. This study aims to identify hazards, assess risk levels and patterns, and formulate risk-control priorities for 15 work types in the construction of the International Research Center (IRC) and Water Waste Treatment Plant (WWTP) buildings at the University of Lampung. Job Safety Analysis (JSA) was used to break down work steps and identify hazards, while Hazard Identification, Risk Assessment, and Risk Control (HIRARC) was used to assess risk with the AS/NZS 4360:2004 matrix and to formulate controls based on the ISO 45001:2018 hierarchy. Data were collected through a questionnaire validated by five experts and completed by 20 respondents; the probability and severity score of each risk was set from the mean of respondent ratings. The study identified 86 potential risks, consisting of 63 medium risks (73%) and 23 low risks (27%), with no high risks. All severity scores were at levels 1–2, so the maximum risk score was 6, and 53 of the 63 medium risks were a combination of severity level 2 with probability levels 2–3. Nineteen risks with a score of 6 were set as priorities, and electrical hazards formed the hazard group with the highest mean score (5.6). Recommended controls consisted of engineering controls (48.8%), administrative controls (24.4%), PPE (24.4%), and substitution (2.3%), with no elimination option. The study concludes that project risks are low to medium as perceived by respondents under existing controls, and contributes a risk priority list and a mapping of recommended controls to the hierarchy of controls that can serve as a reference for preparing Construction Safety Plans (RKK) in similar building projects.
