Abstract

The construction industry in Indonesia is experiencing rapid growth, contributing 9.92% of Indonesia's GDP by 2023. Safety in construction projects is a major concern in every step and decision taken due to the many risks of work accidents that can occur in this service sector. The object studied in this research is the Wood Pellet Factory construction project located in Kelapa Lima Village, East Popayato District, Pohuwato Regency, Gorontalo Province, Indonesia. The scope of work studied in this project are soil, foundation, and factory structure works. The purpose of this research is to identify the possibility of hazards and risks, analyze dominant risk of work accidents, and identify what efforts can be made to prevent and control risks that are categorized as extreme (dominant) risk in the Wood Pellet Factory construction project in Gorontalo. In its preparation, this research uses the HIRARC method and references ISO 31000 (2018) and Guidelines for Hazard Identification, Risk Assessment, and Risk Control (HIRARC), Malaysia (2008). From the results of the risk analysis, there are 173 risks relevant to field conditions and 5 risks that are categorized as extreme risks. Extreme risks are found in variables a.1.1 (Workers around the Excavator were hit by the Excavator Bucket), f.3.2 (Workers were hit by steel rebar that was lifted), h.2.7 (Workers were hit by falling materials), k.2.5 (Steel main structure fell onto workers), and m.2.6 (Workers fell from a height). Risks categorized as extreme risks will be controlled using the HIRARC method. There are four risk mitigation categories of avoidance, reduction, transfer, and acceptance and the hierarchy of control includes elimination, substitution, engineering controls, administrative controls, and PPE. The most effective and low cost risk mitigation is risk reduction, which incorporates substitution, engineering controls, administrative controls, and PPE. If risk control has been implemented effectively, monitoring and re-evaluation of residual risk must still be carried out. After calculating the residual risk re-evaluation, the results of the previous risk calculation were 16 (extreme risk) to 4 (moderate risk), which indicates that the risk control carried out has succeeded in making the risk reduced. This makes the project run optimally and achieve the goal of zero accident.
