Abstract : CV Bintari Jaya Abadi is a company engaged in andesite stone mining. The actual productivity of the excavator at the CV Bintari Jaya Abadi quarry in January 2024 was recorded at 9,494.8111 BCM, while the hauling equipment achieved 9,362.83824 BCM, with a match factor of 0.68. This resulted in the current andesite mining target not being achieved, where the targeted andesite rock removal at CV Bintari Jaya Abadi is 11,538 BCM per month. The research method used involved the calculation and quantitative analysis of the factors affecting the match factor between loading and hauling equipment in andesite mining activities at CV Bintari Jaya Abadi. Improvement efforts aimed at achieving optimal productivity and operational compatibility were carried out by optimizing the cycle times of both the loading and hauling equipment. As a result, the productivity of the loading equipment increased by 34.71% to 12,790.0415 BCM/month, and the productivity of the hauling equipment increased by 76.34% to 16,509.7606 BCM/month, successfully meeting and even exceeding the target set by CV Bintari Jaya Abadi of 11,538 BCM/month, with a match factor of 0.94.

Keywords : Cycle Time; Delay Time; Match Factor; Production; Work Efficiency
