Quantitative analysis reveals actual excavator productivity of 40.8 m³/hour in Jakarta MRT excavation, suggesting optimal equipment allocation.

The actual productivity of the Caterpillar 320 excavator is 40.8 m³/hour, while theoretical potential is 45.8 m³/hour.
To achieve project targets efficiently, four dump trucks with 24 m³ capacity each are necessary to support the excavator.
Field observations and interviews provided primary data that informed the productivity analysis in heavy equipment.
Optimal allocation of heavy equipment could reduce project duration and costs, guiding future infrastructure planning.

Rudiyansa et al. (2025) studied this question.
