This study aims to analyze energy savings from the implementation of the Ventilation on Demand (VoD) system in the underground mine of Big Gossan, PT Freeport Indonesia. The existing ventilation system operates continuously, leading to energy waste and hazardous air recirculation. By employing simulation methods and direct data collection, this research evaluates the optimal air supply requirements and compares them with actual supply, revealing a significant difference of 66%. The analysis results indicate that the implementation of VoD can save energy on the auxiliary fan amounting to $195,365.22 in August 2024. This research is expected to contribute to enhancing the efficiency of mine ventilation systems and improving workplace safety in underground mining environments.
