Masalah: Sistem distribusi jaringan tegangan menengah (20 kV) sisi udara di Bandar Udara Internasional Zainuddin Abdul Madjid Lombok sering mengalami simultaneous trip (trip serentak) pada gardu B2, B3, B4, B5, dan B7 saat terjadi gangguan fasa tunggal maupun multi-fasa. Alasan & Tujuan: Investigasi mendalam diperlukan karena kegagalan suplai pada fasilitas airside mengancam keselamatan penerbangan (flight safety). Penelitian ini bertujuan menganalisis indeks keandalan sistem dan mengevaluasi kinerja koordinasi proteksi eksisting. Metode: Penelitian menggunakan pendekatan kuantitatif dan simulatif dengan mengintegrasikan perhitungan manual standar IEEE 1366-2012 dan pemodelan software ETAP 24.01 berdasarkan log gangguan aktual tahun 2021. Hasil: Perhitungan menunjukkan nilai SAIFI sebesar 5,00 kali/pelanggan/tahun, SAIDI 9,70 jam/pelanggan/tahun, CAIDI 2,425 jam/gangguan, dan ENS 1.739,2 kWh/tahun. Evaluasi kurva Time Current Characteristic (TCC) membuktikan jarak koordinasi (grading time) antar relay hulu-hilir mendekati 0 detik (GT ≈ 0) akibat penyetelan pickup (OCR 50 A, instan 150 A) yang seragam di seluruh gardu. Kesimpulan & Rekomendasi: Sistem proteksi eksisting tidak selektif dalam topologi looping. Direkomendasikan melakukan re-setting relay proteksi, mengimplementasikan Directional Over Current Relay (DOCR), differential relay, serta mengintegrasikan sistem pemantauan berbasis SCADA.
