<![CDATA[Earthwork in an industrial development requires heavy-equipment management that balances productivity, project duration, and operating cost. This study analyzes equipment productivity, fleet requirements, completion time, and operating costs for an excavator, dump trucks, and a bulldozer in the Sumedang Industrial Polis Project, and compares 120-day and 90-day execution scenarios. A quantitative technical-analysis approach was applied using primary data from cycle-time observations, operating conditions, and field observations, together with secondary data on work volume, equipment specifications, working hours, and operating costs. The excavation volume was 48,944 m³ and the corresponding loose-soil volume used in the analysis was 61,180 m³. The calculated basic productivity was 105.727 m³/hour for the excavator, 28.518 m³/hour for each dump truck, and 134.864 m³/hour for the bulldozer. The required fleet remained one excavator, three dump trucks, and one bulldozer in both scenarios. Shortening the schedule to 90 days increased the required effective excavator productivity from 63.730 to 84.972 m³/hour, which remained below the available capacity. Total operating cost decreased from IDR 3,840,081,528 to IDR 3,532,483,608, producing a saving of IDR 307,597,920 or approximately 8.01%. Therefore, with the same equipment configuration, the 90-day scenario provides a shorter execution period and a lower operating cost.]]>
