Abstract

Kebakaran pada RU-VI Balongan telah dilakukan investigasi oleh beberapa pihak dengan kesimpulan bahwa kebakaran terjadi akibat sambaran petir atau induksi pada tangki. Berdasarkan kondisi tersebut, penulis terdorong untuk melakukan perencanaan pembangunan kembali tangki yang dilengkapi dengan foam system dan sistem penangkal petir sebagai upaya penanggulangan kebakaran di area tangki. Ukuran tangki yang baru dihitung dengan mengacu pada NFPA 30. Metode penelitian ini menggunakan teknik analisis data dengan standar dari United States Nuclear Regulatory Commision untuk menentukan besar potensi kebakaran dan data untuk menentukan kebutuhan media pemadam. Pada data tersebut dibuat gambar menggunakan software Autocad. Penelitian ini mengembangkan skenario kebakaran Unobstructed full liquid surface fire yaitu kebakaran yang terjadi karena atap tangki lepas akibat ledakan atau kelebihan tekanan sehingga terbentuk pool fire. Selanjutnya merancang instalasi foam chamber yang meliputi kebutuhan media pemadaman, jumlah foam chamber, sistem perpipaan dan daya pompa serta menentukan alat proteksi petir pada tangki. Kesimpulan pada penelitian ini yaitu tangki berdiameter 45 meter membutuhkan media pemadaman 2.868.851 liter air, 10.754 liter konsentrat busa, foam chamber berjumlah 4 unit, laju aliran 1.629,4 liter/menit dan tingkat III proteksi petir dengan grounding system menggunakan tipe A, batang elektroda vertikal berjumlah 2. ***** The fire at RU-VI Balongan has been investigated by multiple parties, with the conclusion that the fire occurred due to a lightning strike or tank induction. Based on this situation, the author is prompted to undertake the planning of reconstructing the tank, equipped with a foam system and lightning protection system, as an effort to address fires in the tank area. The dimensions of the new tank are calculated in accordance with NFPA 30. This research methodology employs data analysis techniques following the standards of the United States Nuclear Regulatory Commission to determine the potential size of the fire and data to specify the fire suppression media requirements. Drawings are then created based on this data using AutoCAD software. This study develops a scenario of an Unobstructed Full Liquid Surface Fire, which is a fire that occurs due to the tank roof detaching from an explosion or excess pressure, resulting in a pool fire. Subsequently, the design of the foam chamber installation includes the fire suppression media requirements, the number of foam chambers, the piping system, pump power, and the determination of lightning protection equipment for the tank. The conclusion of this research is that a tank with a diameter of 45 meters requires 2,868,851 liters of water as fire suppression media, 10,754 liters of foam concentrate, 4 units of foam chambers, a flow rate of 1,629.4 liters/minute, and level III lightning protection with a grounding system using Type A, consisting of 2 vertical electrode rods.
