ANALISIS INTENSITAS CAHAYA FLOODLIGHT DI BANDAR UDARA CAKRABHUWANA CIREBON

Sistem pencahayaan flood light pada apron diperlukan untuk mendukung visibilitas dan keselamatan kegiatan operasional pada malam hari. Penelitian ini bertujuan menganalisis tingkat iluminansi horizontal, keseragaman, dan distribusi pencahayaan flood light pada apron Bandar Udara Cakrabhuwana Cirebon serta mengevaluasi kesesuaiannya terhadap standar yang berlaku. Penelitian menggunakan pendekatan deskriptif kuantitatif dengan pengukuran langsung menggunakan lux meter pada 150 titik berbasis grid. Prosedur pengukuran mengacu pada SNI 7062:2019, sedangkan evaluasi pencahayaan mengacu pada PR 8 Tahun 2022. Hasil pengukuran lapangan menunjukkan iluminansi rata-rata (Eavg) sebesar 3,96 lux, iluminansi minimum (Emin) sebesar 0 lux, iluminansi maksimum (Emax) sebesar 35 lux, dan uniformity (U0) sebesar 0. Hasil tersebut masih berada di bawah acuan iluminansi horizontal rata-rata sekurang-kurangnya 20 lux dan persyaratan uniformity 0,25 yang ekuivalen dengan perbandingan 1:4. Sebagai validasi pendukung, kondisi eksisting disimulasikan menggunakan DIALux evo dengan armatur substitusi BVP153 G3 LED200 CW 200W karena data fotometrik IES/LDT lampu Krisbow 200 W yang terpasang tidak tersedia. Hasil simulasi menunjukkan Eavg sebesar 3,07 lux, Emin sebesar 0,23 lux, Emax sebesar 36,9 lux, dan U0 sebesar 0,075. Meskipun terdapat perbedaan numerik, hasil simulasi memberikan arah evaluasi yang sama dengan pengukuran lapangan, yaitu tingkat iluminansi rata-rata dan keseragaman pencahayaan eksisting belum memenuhi acuan yang digunakan. Oleh karena itu, diperlukan pemeriksaan kondisi lampu dan armatur, pembersihan, evaluasi arah penyinaran (aiming), serta pengukuran ulang setelah tindakan perbaikan dilakukan. // Apron lighting plays an important role in supporting the safety and continuity of aircraft ground operations at night. Based on the initial observation at Cakrabhuwana Airport, Cirebon, the lighting distribution in the apron area appeared uneven, and several areas were visibly darker. This study aims to measure and analyze the horizontal illuminance and lighting uniformity of the apron floodlight system and to compare the results with the applicable lighting standard. A quantitative method was applied through direct measurements using a lux meter at 150 measurement points arranged in a grid pattern. The measurement data were processed to determine the average illuminance (Eavg), minimum illuminance (Emin), maximum illuminance (Emax), and lighting uniformity. The results showed that the average illuminance was 3.96 lux, the minimum illuminance was 0 lux, and the maximum illuminance was 35 lux. The uniformity value, calculated using the ratio of Emin to Eavg, was 0:3.96. This result did not meet the required lighting uniformity comparison of 1:4. The average illuminance also did not meet the minimum apron lighting standard of 20 lux. The lighting distribution was uneven because several measurement points received no measurable illumination. Therefore, it is necessary to evaluate the condition of the lamps, clean the luminaires, readjust the floodlight aiming directions, and conduct photometric analysis before adding or modifying the existing lighting installation.
