Planning for the Subgrade Preparation of the Inspection Road at Depati Parbo Kerinci Jambi Airport

Abstract

Depati Parbo Airport, located in Kerinci Regency, Jambi Province, is currently undergoing airside
facility development to improve flight safety and operational efficiency. One of the essential
supporting infrastructures that needs to be realized is the inspection road, which functions as a
route for routine monitoring, perimeter surveillance, and facility maintenance access. This study
aims to plan the subgrade preparation of the inspection road based on existing conditions, as the
area consists of former rice fields with low bearing capacity soil, requiring ground improvement
before pavement construction. The type of research used is applied research. Data were obtained
through field observation during the On the Job Training 2 at the Airport Operator Unit of Depati
Parbo Airport, and supported by secondary data such as topographic maps from DEMNAS, the
airport master plan, and the 2024 Jambi Provincial Standard Unit Prices (HSPK). The population
in this study includes the entire inspection road area of 4,437 meters in length, with samples taken
at cross-sectional analysis points every 50 meters, totaling 92 points. Based on the results of the
calculations, the cut volume is estimated at 44,303.49 m³, while the fill volume is approximately
22,814.37 m³. The estimated total cost for the subgrade preparation work reaches IDR
17,450,000,000.00. The outcome of this planning is expected to serve as a reference for field
implementation and contribute to enhancing the safety and performance of airside infrastructure at
Depati Parbo Airport.
