Abstract

Metode analisis risiko bahaya saat ini sudah berkembang seiring kemajuan teknologi untuk hasil analisis yang lebih akurat. Analisis risiko HAZOP yang lebih terfokus kepada
komponen sistem dan identifikasi risiko secara berurutan. Namun metode HAZOP cenderung mengabaikan interaksi antara komponen sistem dan keterkaitan antara komponen sistem,
manusia, proses yang dapat mempengaruhi bahaya. Di sisi lain, metode STPA memberikan pendekatan terhadap interaksi komponen, manusia, serta proses. Untuk mendapatkan analisis
bahaya dilakukan keandalan terhadap peralatan untuk mengetahui nilai keandalan serta waktu perawatan terhadap peralatan yang dikaji. Equipment yang dikaji meliputi TE-1283, TE-1246, TE-1247, SV-1224. Didapatkan nilai R(t) sebesar 65% ketika TE-1283 selama 5580 jam, TE-1246 selama 5580 jam, TE-1247 selama 6400 jam, SV-1224 selama 3530 jam. Untuk analisis risiko bahaya pada unit proses oksidasi didapatkan hasil identifikasi bahaya STPA terdapat 21
bahaya meliputi 4 identifikasi bahaya pada component error, 6 identifikasi bahaya pada human error, 7 identifikasi bahaya pada organizational error, 4 bahaya pada system dan design error.
Total error pada kategori bahaya component error sebesar 19.05% , organizational error sebesar 33.33%, human error 28.57%, design atau system error sebesar 19.05% =====================================================================================================================================
The method of hazard risk analysis has evolved with technological advancements to achieve more accurate analysis results. HAZOP analysis focuses more on system components
and sequentially identifies risks. However, the HAZOP method tends to overlook the interactions between system components and the interdependencies among system components, humans, and processes that can influence hazards. On the other hand, the STPA method provides an approach to address the interactions among components, humans, and processes.
To obtain hazard analysis, reliability analysis is conducted on the equipment to determine reliability values and maintenance times for the studied equipment. The analyzed equipment includes TE-1283, TE-1246, TE-1247, and SV-1224. The obtained R(t) values are 65% for TE-1283 over 5580 hours, TE-1246 over 5580 hours, TE-1247 over 6400 hours, and SV-1224 over 3530 hours. For hazard risk analysis in the oxidation process unit, the STPA method identified a total of 21 hazards, including 4 hazards related to component error, 6 hazards related to human error, 7 hazards related to organizational error, and 4 hazards related to system and design error. The total error percentage for the category of component error is 19.05%, organizational error is 33.33%, human error is 28.57%, and design or system error is 19.05%.
