Abstract

Penelitian ini berjudul Implementasi CASR Part 830 dalam Investigasi Kecelakaan Pesawat Udara Sipil di Indonesia dan bertujuan untuk mengkaji penerapan regulasi Civil Aviation Safety Regulation Part 830 yang diadopsi melalui Peraturan Menteri Perhubungan Nomor 14 Tahun 2015 tentang pelaporan dan investigasi kecelakaan pesawat udara sipil. Objek penelitian ini adalah proses investigasi yang dilakukan oleh Komite Nasional Keselamatan Transportasi (KNKT) dalam menanggapi insiden penerbangan di Indonesia. Penelitian ini menggunakan pendekatan yuridis-normatif dan studi pustaka terhadap dokumen peraturan perundang-undangan serta jurnal ilmiah terindeks SINTA yang relevan. Hasil penelitian menunjukkan bahwa penerapan CASR Part 830 telah menjadi acuan prosedural dalam proses investigasi kecelakaan pesawat di Indonesia, namun masih terdapat tantangan dalam hal keterbukaan informasi publik dan tindak lanjut terhadap rekomendasi keselamatan yang dikeluarkan oleh KNKT. Studi kasus kecelakaan Lion Air JT‑610 dan Sriwijaya Air SJ‑182 menunjukkan bahwa proses investigasi telah mengikuti prosedur internasional, tetapi implementasi hasil investigasi masih lemah dalam hal pengawasan dan akuntabilitas pihak terkait. Oleh karena itu, dibutuhkan penguatan regulasi dalam hal kewajiban pelaporan, transparansi publik, serta sanksi administratif terhadap pihak yang tidak menindaklanjuti rekomendasi keselamatan.

Abstract

This study presents a field-based performance analysis of turbofan gas turbine engines operating in Indonesia’s commercial aviation sector under tropical environmental conditions. The research focuses on how ambient temperature, humidity, operational frequency, and short-haul flight patterns influence actual engine performance relative to ideal thermodynamic expectations. A mixed-method design was applied by combining literature-based Brayton-cycle modeling with empirical operational data from CFM56 and V2500 engine families. Data sources included engine logbooks, maintenance records, operational observations, and ambient condition monitoring at selected Indonesian airports. The analysis shows that actual specific fuel consumption (SFC) was consistently 5-10% higher than theoretical estimates under high-temperature operating conditions, particularly above 30 °C. Field observations also indicated reduced thrust margins, increased exhaust gas temperature (EGT), and decreasing propulsive efficiency during high-load flight phases, especially takeoff and climb. These deviations confirm that tropical operating conditions and repetitive short-sector utilization accelerate performance deterioration beyond ideal-cycle assumptions. The main scientific contribution of this study is the demonstration that Brayton-cycle-based turbofan performance prediction for Indonesian commercial aviation requires correction for local environmental and operational factors. The findings support the use of climate-adaptive performance assessment and condition-based maintenance strategies to improve engine efficiency, reliability, and operational safety.
