This study analyzes the effectiveness of airport function separation in Indonesia as a strategic response to airspace congestion, operational inefficiencies, and overlapping civil-military airport usage. Focusing on Soekarno-Hatta (CGK), Halim Perdanakusuma (HLP), and Kertajati (KJT) Airports, the study adopts a qualitative-descriptive method supported by indepth interviews with stakeholders from the Ministry of Transportation, Indonesian Air Force (TNI-AU), airport operators, airlines, and aviation experts. The findings reveal that overlapping functions at Halim generate flight delays, coordination difficulties, and safety risks, while Soekarno-Hatta faces high traffic volume with limited relief options. Meanwhile, Kertajati remains underutilized despite having modern infrastructure and a strategic location. Drawing on international best practices, such as Japan’s Narita-Haneda-Chōfu model and similar systems in the US and UK, the study proposes a five-function airport classification: international commercial, domestic commercial, state/VVIP, military, and private/general aviation. It recommends formalizing a national regulation on function separation, reclassifying Halim for exclusive state and military use, and optimizing Kertajati through Public-Private Partnerships (PPPs) supported by regulatory incentives. Establishing a civil-military coordination body is also urged to enhance airspace governance. The novelty of this study lies in its integrated policy framework, which combines regulatory, institutional, and operational dimensions. Unlike previous studies that focus only on Jakarta’s traffic management or civilmilitary coordination, this research introduces Kertajati as a national hub for private and general aviation, an approach that remains underexplored in Indonesian aviation discourse and presents a viable solution to redistribute traffic and improve national airspace efficiency. © 2025 by MIP
