Obstruction Zone Modeling at Halim Perdanakusuma Airport using Remote Sensing Data

Flight safety plays a critical role in both the national economy and military defense. According to National Transportation Safety Board (NTSB), highest number of aircraft accidents between 2013 2018 occurred during takeoff (24%) landing (40%). To model obstruction zone based on building density its impact flight safety, this study utilizes remote sensing data from Sentinel 2A 2022. The is analyzed using Normalized Difference Built-up Index (NDBI) algorithm, which serves as basis for modeling potential accident zones. Specifically, focuses growth buildings within 15 km extended runway area landing. findings reveal that approach Operation Zone (KKOP) at Halim Perdanakusuma Airport exhibits density. This demonstrates moderate level density, with prevailing pattern extend predominantly eastward, toward Bekasi city. Furthermore, highlights nearly entire region falls under classification "built-up areas." Consequently, establishing urban planning policies development around corridors becomes imperative while considering aviation factors. research provides valuable insights authorities decision-makers involved infrastructure planning. By taking into account surrounding areas along paths, appropriate measures can be implemented ensure optimal mitigate risk future
