PERENCANAAN PENGEMBANGAN GEOMETRIK DAN PERKERASAN RUNWAY PADA BANDARA SEPINGGAN BALIKPAPAN

Abstract

Sultan Aji Muhammad Sulaiman Sepinggan Airport Balikpapan is located in Balikpapan City, East Kalimantan at an altitude of 4 meters above sea level which has 1 runway. In 2019, the government officially announced that the capital would be moved from Jakarta to East Kalimantan. With the relocation of the capital city, SAMS Sepinggan Airport is predicted to become the main gateway to the capital city. So it is necessary to pay attention to the existing facilities at the airport, whether they are still able to accommodate the maximum movement of aircraft until 2030. The research conducted will focus on the development of the runway, in terms of geometric and pavement. The research method is based on regulations issued by the Dirjen Perhubungan Udara and civil aviation organizations such as ICAO and FAA. The research was conducted by conducting a literature study, then collecting the required data, then analyzing the data and after that conclusions could be drawn. The required data include wind data, aircraft movement data, flight schedules, airport elevation, airport temperature, subgrade CBR data and existing runway pavement thickness data. The analysis carried out is evaluating the direction of the runway, forecasting the movement of aircraft, calculating the capacity of the existing runway, planning the runway geometric and calculating the thickness requirement of the runway pavement. The results of the analysis carried out show that the direction of the existing runway is still relevant to use, namely in the direction of 07-25 with wind coverage of 99.75%. In 2030, it is predicted that there will be 117,946 aircraft movements with a rush hour volume of 59 operations/hour. The existing runway capacity is capable of serving up to 33 operations/hour. The current runway is no longer able to accommodate movement at peak hours in 2030. So the runway needs to be developed geometrically to increase its capacity. The runway length requirement after being calculated is 3,015 meters with a width of 45 meters, which means that there needs to be a runway extension in the 70o direction of 515 meters. The total pavement thickness requirement calculated by the graphical method is 112 cm, while the FAARFIELD method is 80 cm. The difference in thickness obtained is caused by differences in the material used, the calculated aircraft load and for the thickness of the surface layer in the graphic method depending on the type of design aircraft.
