Salah satu fase penerbangan yang berkontribusi signifikan terhadap kebisingan adalah fase pendekatan (approach), khususnya pada lintasan Instrument Landing System (ILS). Penelitian ini bertujuan untuk menganalisis jarak aman kawasan permukiman terhadap paparan kebisingan pesawat pada lintasan approach ILS Runway 24 Bandar Udara Halim Perdanakusuma. Metode yang digunakan berupa analisis teoritis tingkat kebisingan berbasis data sertifikasi kebisingan pesawat dari Federal Aviation Administration (FAA), dengan pendekatan perhitungan Sound Pressure Level (SPL) dan asumsi perambatan kebisingan di ruang bebas. Analisis dilakukan pada tiga titik lintasan approach, yaitu 1,8 nm, 3 nm, dan 6 nm, untuk beberapa tipe pesawat yang umum beroperasi. Hasil penelitian menunjukkan bahwa setiap tipe pesawat menghasilkan jarak paparan kebisingan yang berbeda, dengan jarak terjauh dihasilkan oleh Boeing 737-300 (±7,07 km), diikuti Airbus A320-214 (±4,07 km), Dassault Falcon 7X (±3,38 km), dan ATR 72-200 (±2,95 km). Evaluasi pada seluruh titik lintasan menunjukkan bahwa tingkat kebisingan yang dihasilkan masih melampaui ambang batas 55 dBA untuk kawasan permukiman. Hasil penelitian ini diharapkan dapat menjadi referensi awal dalam perencanaan tata ruang kawasan sekitar bandara serta sebagai dasar pengendalian dampak kebisingan penerbangan. Airports play a vital role as centers of transportation and economic activity; however, increasing flight operations can generate noise issues that adversely affect the comfort and health of surrounding communities. One of the flight phases that significantly contributes to aircraft noise is the approach phase, particularly along the Instrument Landing System (ILS) flight path. This study aims to analyze the safe distance of residential areas from aircraft noise exposure along the ILS approach path of Runway 24 at Halim Perdanakusuma Airport. The research employs a theoretical noise analysis based on aircraft noise certification data issued by the Federal Aviation Administration (FAA), using a Sound Pressure Level (SPL) calculation approach with the assumption of free-field noise propagation. The analysis is conducted at three approach points, namely 1.8 nm, 3 nm, and 6 nm, for several aircraft types commonly operating at the airport. The results indicate that each aircraft type produces a different noise exposure distance, with the Boeing 737-300 generating the longest distance (approximately 7.07 km), followed by the Airbus A320-214 (approximately 4.07 km), the Dassault Falcon 7X (approximately 3.38 km), and the ATR 72-200 (approximately 2.95 km). Evaluation at all approach points shows that the noise levels exceed the 55 dBA threshold for residential areas. The findings of this study are expected to serve as an initial reference for spatial planning in airport surrounding areas and as a basis for mitigating the impact of aircraft noise.]]>
