PLANNING OF TURN PAD AREA AT THE END OF THRESHOLD 24 AT NAMROLE AIRPORT, MALUKU PROVINCE

Abstract

Namrole Airport in South Buru Regency, Maluku Province, is a class III airport that requires airside facility development
due to increasing aircraft movements. One of the urgent needs is the construction of a turn pad at the end of runway 24
to support ATR 42-300 aircraft maneuvers so they can turn 180° safely and efficiently. This study aims to plan the turn
pad dimensions, determine the thickness of flexible pavement using the FAA Manual method and FAARFIELD
software, and calculate the Cost Budget Plan (RAB) according to PM 78 of 2014 and HSPK South Buru Regency 2024.
The data used include aircraft specifications, soil CBR values, and flight traffic data, with validation through COMFAA
software to obtain the PCN value. The planning results show that the need for a turn pad area of 325,875 m² with a
pavement thickness of 41 cm (FAA Manual) and 35.6 cm (FAARFIELD). The COMFAA analysis resulted in a PCN of
15.5 F/C/X/T, while the RAB estimate reached Rp524,900,000.00.
