Abstract

PT Five Star Indonesia operates a nickel mine at the PT Wana Kencana Mineral site in East Halmahera, North Maluku. Its production target of 350 tonnes/hour has not been achieved. This study evaluates the productivity of the Sany 365H excavator and Shacman F3000 dump truck, identifies operational constraints, and proposes improvements. The study used literature review, field observations, and primary and secondary data collection. Cycle times, work delays, equipment availability, bucket fill factor, swell factor, and material density were evaluated. Reported actual productivity was 229.86 tonnes/hour for the excavator and 86.80 tonnes/hour for the dump truck, with cycle times of 37.25 seconds and 21.51 minutes, respectively. The reported match factor of 1.29 indicates an imbalance between loading and hauling operations. Identified constraints include a narrow mining front, bottom loading, and work delays. Proposed improvements comprise widening the mining front from 7 to 12 metres, adopting top loading, and improving work efficiency. These measures require verification using consistent cycle-time and fleet data before achievement of the production target can be confirmed.
