“ANALYSIS OF THE SUPER STRUCTURE DESIGN OF THE OPERATIONAL BUILDING AT UPBU CLASS III MELALAN, EAST KALIMANTAN”

Abstract

Melalan Airport in West Kutai (IATA: GHS, ICAO: WALE, formerly WRLE) is located in Gemuhan Asa Village, Barong Tongkok District, approximately 8 km from the city center. Positioned at an elevation of 100.5 meters (330 feet) above sea level, the airport is currently undergoing development, including the construction of a new operational building. This project addresses the increasing need for staff and operational space at the airport. The research method used is a descriptive qualitative approach through data collection. According to the 2023 Term of Reference (TOR) for Melalan Airport, the development plan includes the construction of an operational building to support daily operations and maintenance of airport facilities. The structural design uses the Medium Moment Resisting Frame System (SRPMM), as the area of Sendawar lies within a low to moderate seismic zone (0.05 – 0.1 g). The structure was analyzed using SAP2000 software for earthquake-resistant design. The final design includes main beams of 25 × 40 cm, secondary beams of 20 × 15 cm, slab thickness of 11 cm, and columns of 40 × 40 cm. The total construction cost for the operational building is estimated at Rp 1,215,000,000.00 (One billion two hundred fifteen million rupiah).
