The Lolak Bolaang Mongondow Airport Runway and Taxiway Project represents one of the emerging airport developments characterized by a heightened susceptibility to accidents. Occupational Safety and Health (K3), an integral component of multifaceted initiatives aimed at mitigating workplace accidents while augmenting labor productivity and efficiency, has been effectively integrated into this undertaking. Among the methodologies employed for its implementation, the Hazard Identification and Risk Assessment Risk Control (HIRARC) approach takes precedence. The primary objective of this research is to meticulously identify hazards, conduct a comprehensive analysis of workplace safety risks, and institute measures to curtail these risks within the scope of the Lolak Bolaang Mongondow Airport Runway and Taxiway project. This endeavor seeks to curtail, and ideally eliminate, workplace accidents. Data acquisition was facilitated through a combination of observational techniques and structured interviews with service providers and construction contractors, involving 63 respondents. To ascertain the categorization of risk levels, spanning from low to high, a meticulous workplace safety risk analysis was executed. The outcome of this analysis, encompassing a total of 69 sub-items of work, reveals that the highest risk level is attributed to runway construction work, accounting for 53% of the identified risks (9 out of 17). The second-highest risk category pertains to PKP-PK work, constituting 40% of the 40 identified risks, and the third-highest risk level is linked to operational road pavement construction, with a risk percentage of 31%. Subsequent to the identification and assessment of risks, risk control measures are diligently executed. This phase signifies the culmination of data processing within the framework of the HIRARC methodology.
