<![CDATA[ This study aims to comprehensively analyze the implementation of Job Safety Analysis (JSA) in the quartz sand mining system at PT X, Kerek District, Tuban Regency, East Java Province. Open-pit mining activities take place in a dynamic and fluctuating work environment, creating significant hazards throughout each production cycle. This study uses a qualitative descriptive method involving direct field observations, technical documentation, and in-depth interviews with the Safety Officer and heavy-equipment operators. Risk levels were analyzed and assessed using Likelihood and Severity parameters based on the AS/NZS 4360 risk management standard and ISO 45001. Hazard identification across four main observation areas—the mechanical condition of excavation, loading, and hauling equipment; workforce operating behavior; loading methods; and haul-road geometry—showed that all identified risks were categorized as High Risk, accounting for a cumulative 100%. The dominant risks included collisions between heavy equipment due to limited visibility, workers being struck in blind-spot areas, road subsidence or vehicle skidding on haul roads, and low compliance with the use of personal protective equipment (PPE). Based on these findings, corrective-action recommendations were developed using the hierarchy of risk controls (engineering controls, administrative controls, and PPE) to reduce operational risks to an acceptable level (As Low as Reasonably Practicable) and achieve safe and sustainable operational excellence.]]>
