Abstract

Fasilitas Stasiun Pengumpul Minyak memiliki potensi bahaya yang tinggi karena menangani hidrokarbon mudah terbakar dalam jumlah besar serta menggunakan berbagai peralatan bertekanan yang berpotensi menimbulkan kebakaran dan ledakan. Kompleksitas proses, inventori hidrokarbon yang besar, serta potensi dampak terhadap pekerja, aset, lingkungan, dan masyarakat sekitar menjadikan pengelolaan risiko pada fasilitas ini sangat penting. Oleh karena itu, diperlukan analisis risiko yang komprehensif untuk mengidentifikasi potensi bahaya, mengevaluasi tingkat risiko, serta menentukan langkah pengendalian yang tepat guna mencegah kecelakaan mayor. Penelitian ini bertujuan untuk menganalisis risiko kebakaran dan ledakan akibat kegagalan operasional pada fasilitas SP Mangun Jaya PT XYZ. Penelitian dilakukan menggunakan metode Hazard and Operability Study (HAZOP), Major Accident Hazard (MAH), Event Tree Analysis (ETA), dan perangkat lunak PHAST. Data primer diperoleh dari P&ID, parameter operasi, inventori bahan, sistem proteksi, data inspeksi, observasi lapangan, serta Focus Group Discussion (FGD) yang melibatkan personel operasi, maintenance, process safety, dan HSSE. HAZOP digunakan untuk mengidentifikasi potensi bahaya dan deviasi proses, ETA untuk menganalisis probabilitas perkembangan skenario kecelakaan, sedangkan PHAST digunakan untuk memodelkan konsekuensi berupa dispersi gas dan radiasi panas. Hasil penelitian menunjukkan bahwa risiko terbesar didominasi oleh skenario kehilangan containment hidrokarbon pada Sand Filter, Separator, Scrubber, Production Tank, Wash Tank, dan Test Tank akibat high pressure, high level, kegagalan sistem venting, korosi, serta kegagalan instrumentasi. Hasil ETA menunjukkan bahwa skenario dominan berupa liquid pool dan gas dispersion dengan area paling kritis berada pada ISO_03L dan ISO_04L. Hasil pemodelan PHAST menunjukkan bahwa konsekuensi terbesar berasal dari skenario pool fire pada ISO_03L yang berpotensi mempengaruhi keselamatan personel, jalur evakuasi, dan akses tanggap darurat. Penelitian ini menyimpulkan bahwa ISO_03L merupakan area dengan tingkat risiko dan konsekuensi terbesar sehingga menjadi prioritas utama dalam pengendalian risiko dan peningkatan keselamatan proses.

Oil Gathering Stations have a high hazard potential due to the handling of large quantities of flammable hydrocarbons and the operation of pressurized equipment that may lead to fires and explosions. Process complexity, large hydrocarbon inventories, and the potential impact on personnel, assets, the environment, and surrounding communities make risk management a critical aspect of facility operation. Therefore, a comprehensive risk assessment is required to identify potential hazards, evaluate risk levels, and determine appropriate control measures to prevent major accidents. This study aims to analyze fire and explosion risks resulting from operational failures at the SP Mangun Jaya facility of PT XYZ. The study employs Hazard and Operability Study (HAZOP), Major Accident Hazard (MAH), Event Tree Analysis (ETA), and PHAST software. Primary data were obtained from Piping and Instrumentation Diagrams (P&ID), operating parameters, material inventories, protection systems, inspection records, field observations, and Focus Group Discussions (FGD) involving operations, maintenance, process safety, and HSSE personnel. HAZOP was used to identify process deviations and hazards, ETA was applied to evaluate the probability of accident scenario development, while PHAST was used to model accident consequences such as gas dispersion and thermal radiation.
The results indicate that the highest risks are associated with hydrocarbon loss of containment scenarios involving the Sand Filter, Separator, Scrubber, Production Tank, Wash Tank, and Test Tank due to high pressure, high level, venting system failures, corrosion, and instrumentation failures. ETA results show that the dominant accident scenarios are liquid pools and gas dispersion, with ISO_03L and ISO_04L identified as the most critical areas. PHAST modeling demonstrates that the most significant consequence is a pool fire scenario in ISO_03L, which may affect personnel safety, evacuation routes, and emergency response access. The study concludes that ISO_03L represents the area with the highest risk and consequence level and should therefore be prioritized for risk control and process safety improvement.
