PERENCANAAN PENGEMBANGAN DAN PERKERASAN RUNWAY BANDARA SULTAN MUHAMMAD KAHARUDDIN SUMBAWA NUSA TENGGARA BARAT MENGGUNAKAN METODE CBR DAN FAA

Sultan Muhammad Kaharuddin Airport is a class III airport located in Sumbawa Regency, West Nusa Tenggara Province. The airport has a runway of 1,800 m × 30 m and the ATR 72-600 aircraft is the largest aircraft type that can currently be landed at this airport, it is planned to develop the runway to serve larger aircraft types,namely the B737-500 type. After planning using the B737-500 type aircraft, the ARFL (Aerodrome Reference Field Length) calculation of the Sultan Muhammad Kaharuddin Airport runway will be developed to 2277 m × 45 m. In this final project, the runway pavement structure planning uses two methods, namely the California Bearing Ratio (CBR) method with a total pavement thickness of 45 inches or 114 cm, and the Federal Aviation Administration (FAA) method with a total pavement thickness of 25 inches or 63.3 cm. The cost Budget Plan Cost (RAB) of Sultan Muhammad Kaharuddin airport uses the CBR method because compared to FAA, CBR is superior in terms of safety because it has a thicker pavement thickness. Obtained a total calculation of the Budget Plan Cost (RAB) for the development of runway at Sultan Muhammad Kaharuddin Airport with the CBR method the total planned cost reached Rp 81,106,433,669.52.
