RANCANG BANGUN DRIVER POWER SUPPLY LAMPU TAXIWAY GUIDANCE SIGN (TGS) TIPE LED DI BANDAR UDARA BUDIARTO

Taxiway Guidance Sign (TGS) merupakan bagian dari Airfield Lighting System (AFL) yang berfungsi memberikan informasi dan panduan visual kepada pilot selama pergerakan pesawat di area taxiway. Keandalan TGS didukung oleh kinerja driver power supply yang berfungsi menyediakan catu daya bagi modul LED. Berdasarkan hasil observasi di Bandar Udara Budiarto, kerusakan driver power supply menyebabkan lampu TGS tidak dapat beroperasi, sementara Constant Current Regulator (CCR) dan series isolating transformer masih berfungsi dengan baik. Selain itu, keterbatasan ketersediaan suku cadang asli, biaya pengadaan yang relatif tinggi, serta waktu pengadaan yang lama dapat menghambat proses pemeliharaan fasilitas TGS. Oleh karena itu, penelitian ini bertujuan merancang dan membangun driver power supply alternatif untuk TGS tipe LED yang lebih efisien dari segi biaya dan waktu pengadaan dengan menggunakan komponen elektronik yang mudah diperoleh di pasaran. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan ADDIE yang terdiri dari tahap Analysis, Design, Development, Implementation, dan Evaluation. Driver yang dikembangkan terdiri dari transformator toroid, bridge rectifier, kapasitor elektrolit, buck-boost converter, dan modul LED sebagai beban. Pengujian meliputi pengujian fungsi lampu LED, pengujian kondisi short circuit dan open circuit, pengujian ketahanan selama 9 jam, serta pengujian validasi bersama dosen pembimbing dan teknisi kelistrikan Bandar Udara Budiarto. Hasil pengujian menunjukkan bahwa driver yang dikembangkan mampu menghasilkan tegangan keluaran stabil sebesar 24 VDC, beroperasi secara kontinu selama 9 jam tanpa mengalami kegagalan fungsi, serta mempertahankan kondisi nyala LED secara normal tanpa flicker maupun overheating. Dengan demikian, driver yang dikembangkan dapat digunakan sebagai alternatif pengganti driver bawaan pabrikan serta mendukung kemudahan pemeliharaan dan efisiensi pengadaan.

Taxiway Guidance Sign (TGS) is part of the Airfield Lighting System (AFL) that provides visual information and guidance to pilots during aircraft movement on the taxiway. The reliability of TGS is supported by the performance of its power supply driver, which provides electrical power for the LED modules. Based on observations at Budiarto Airport, damage to the TGS driver power supply caused the lamps to become inoperative, while the Constant Current Regulator (CCR) and series isolating transformer were still functioning properly. In addition, the limited availability of original spare parts, relatively high procurement costs, and long procurement times can delay the maintenance of TGS facilities. Therefore, this study aims to design and develop an alternative driver power supply for LED-type TGS that is more efficient in terms of procurement cost and time by using electronic components that are readily available on the market. The research employed the Research and Development (R&D) method using the ADDIE development model, consisting of Analysis, Design, Development, Implementation, and Evaluation. The developed driver consists of a toroidal transformer, bridge rectifier, electrolytic capacitor, buck-boost converter, and LED module as the load. Testing included LED functional testing, short-circuit and open-circuit condition testing, a 9-hour endurance test, and validation testing involving supervisors and electrical technicians at Budiarto Airport. The results showed that the developed driver successfully provided a stable 24 V DC output, operated continuously for 9 hours without functional failure, and maintained normal LED illumination without flickering or overheating. The developed driver can therefore serve as an alternative replacement for the original manufacturer’s driver while supporting easier maintenance and more efficient procurement.
