Analysis of Heavy Equipment Productivity on the Continuation Project of Road Improvement in the Kalibasau – Putri Nurah Area, Gunung Tabur District, Berau Regency

Abstract

The rapid population growth in Indonesia, as a developing country, has driven the increasing demand for infrastructure, particularly road construction. This study aims to analyze the productivity of heavy equipment during the Class B aggregate base course work in the continuation project of road improvement in the Kalibasau–Putri Nurah area, Gunung Tabur District, Berau Regency. The method employed is a descriptive approach with data collection techniques including literature review, field observation, and interviews. The analysis was conducted by comparing actual and planned productivity based on technical formulas and the reference of Minister of Public Works and Public Housing Regulation No. 28/PRT/M/2016. The results indicate that all types of heavy equipment experienced a decrease in productivity compared to the planned values: Wheel Loader by -63.4%, 8 m³ Dump Truck by -38.44%, Motor Grader by -37.38%, and Vibratory Roller by -75.27%. This discrepancy reflects the existence of both technical and non-technical factors in the field that were not fully accounted for during the initial planning. These findings serve as a crucial basis for formulating strategies to improve the operational efficiency of heavy equipment and to develop more realistic and adaptive planning for road construction projects in response to field conditions.
