Analysis of the Productivity of Excavator and Dump Truck Heavy Equipment in the Excavation Works for the Construction of Jakarta MRT Station Cp 203 Phase 2A

Abstract

The increasing demand for transportation infrastructure in urban areas such as Jakarta has led to the implementation of the Jakarta Mass Rapid Transit (MRT) Phase 2A project. One of the key components in this project is the efficiency of heavy equipment usage, particularly excavators and dump trucks, in excavation work. This study aims to analyze the productivity of excavators and dump trucks, calculate production per cycle, hourly production, daily production, and determine the optimal number of equipment units required to meet project completion targets.

The research method uses a quantitative approach by collecting primary data through field observations and interviews, as well as secondary data from project documents. The analysis results show that the Caterpillar 320 excavator has an actual productivity of 40.8 m³/hour, while theoretical calculations indicate a productivity potential of up to 45.8 m³/hour. To support the optimal operation of the excavator, four dump trucks with a capacity of 24 m³ are required. This study provides recommendations for efficient allocation of heavy equipment to optimize project duration and cost. This research is expected to serve as a technical reference for future infrastructure projects in planning heavy equipment requirements effectively.
