Abstract
This paper evaluates the utilization of loading and hauling technology at andesite mine using cycle time and match factor methods. One mine site operated by PT. Anugerah Karya Agra Sentosa was taken as a case study. PT. Anugerah Karya Agra Sentosa located in Mujahiddin Village, Plampang Sub-district, West Sumbawa Regency is an andesite mining using open pit system with quarry type method. Mechanical equipment that operates is one unit Excavator (Kobelco SK 200) capacity 0.9 m3 and five units Dump Truck (Toyota Dyna 130 HT) with bucket capacity 3.6 m3. The analysis results found that the average cycle time for loading equipment was 0.54 minutes while the average cycle time for hauling equipment was 14.58 minutes. Recalculation for match factor (MF=1) resulted in additional of two hauling equipments from five units to seven units (Dump Truck).
