PLANNING FOR THE EXTENSION OF THE RUNWAY TO OPTIMIZE THE ATR 72-600 AIRCRAFT AT NAMROLE AIRPORT, MALUKU

Abstract

Namrole Airport – Maluku is located in Lektama Village, Namrole District, South Buru Regency, Maluku Province. The
airport currently has an existing runway measuring 1,200 meters in length and 30 meters in width, serving ATR 42-300
aircraft. As part of its development plan, a runway extension is proposed to accommodate larger aircraft types,
specifically the ATR 72-600, enabling operations at its maximum take-off weight (MTOW). This study aims to determine
the required runway length based on the Aeroplane Reference Field Length (ARFL), evaluate the strength of the existing
pavement, and design the new pavement thickness using the FAARFIELD 2.1.1 application. The existing pavement was
assessed using Excel spreadsheet calculations and the COMFAA 3.0 program. Pavement strength and cost estimates
were also analyzed using these applications. The analysis results indicate that the existing pavement is still adequate to
support the operation of the planned critical aircraft. The required pavement thickness for the new design is 76 cm, with
a resulting PCN value of 48 F/C/X/T. The estimated construction cost based on the Bill of Quantities (RAB) is Rp
17.380.000.000,00.
