Penelitian ini menilai konsekuensi pelepasan bahan kimia dari tangki penyimpanan Liquefied Petroleum Gas (LPG) bertekanan pada PT. LMI. Penelitian ini adalah kuantitatif. Simulasi pelepasan bahan kimia menggunakan piranti lunak ALOHA (Areal Locations of Hazardous Athmospheres) berdasarkan data primer dan sekunder pada operasi normal. ALOHA memberikan hasil dalam berbagai jangkauan jarak dispersi, kebakaran dan ledakan. Setiap jangkauan jarak diklasifikasikan menjadi tiga kategori: merah, oranye dan kuning berdasarkan tingkat keparahan. Hasil penelitian ini menunjukkan sekolah, klinik medis, pabrik, dan rumah-rumah di sekitar PT. LMI menjadi populasi berisiko tinggi terkena dampak pelepasan bahan kimia dari tangki penyimpanan LPG.

Industri petrokimia, merupakan sektor dengan tingkat risiko tinggi terhadap bahaya kebakaran dan ledakan akibat keterlibatan bahan mudah terbakar, bahan beracun, serta kondisi operasi pada suhu dan tekanan tinggi. Penelitian ini merupakan penelitian deskriptif semi-kuantitatif yang bertujuan untuk mengklasifikasikan area berbahaya pada proses produksi berdasarkan standar API RP 500 serta menentukan tingkat risiko kebakaran dan ledakan dalam proses produksi gas amonia menggunakan metode DF&EI. Pendekatan metodologis yang digunakan meliputi identifikasi bahan kimia berbahaya, penilaian tingkat bahaya menggunakan metode DF&EI, analisis estimasi kerugian dan radius paparan, serta kajian tingkat dispersi gas amonia dan ledakan proses yang dihasilkan selama proses produksi menggunakan software ALOHA. Hasil analisis menunjukkan bahwa Plant 1A memiliki indeks DF&EI pada kategori parah (severe), radius paparan 223,78m, dan actual MPPD 154 miliar pada unit ammonia converter dan ringan (light), radius paparan 45,78, dan actual MPPD 47 miliar pada unit reaktor urea. Klasifikasi area berbahaya mengindikasikan keberadaan zona klasifikasi kelas I, divisi 2 di beberapa titik proses produksi yang berdekatan dengan sumber pelepasan uap amonia dan gas alam. Skenario terburuk menunjukan adanya dampak kerugian yang luas akibat ledakan dari unit ammonia converter sejauh 269m menyebabkan kerusakan kaca bangunan dan sebaran gas ammonia sejauh 10km pada reaktor urea menyebabkan ganguan pernapasan.
The petrochemical industry is a high-risk sector for fire and explosion hazards due to the involvement of flammable and toxic substances, as well as operating conditions at high temperatures and pressures. This study is a semi-quantitative descriptive research aimed at classifying hazardous areas in the production process based on the API RP 500 standard and determining the level of fire and explosion risk in the ammonia gas production process using the Dow’s Fire and Explosion Index (DF&EI) method. The methodological approach includes the identification of hazardous chemicals, hazard level assessment using DF&EI, analysis of loss estimation and exposure radius, and assessment of ammonia gas dispersion and process explosion using the ALOHA software. The analysis results show that Plant 1A has a DF&EI index categorized as severe, with an exposure radius of 223.78 meters and an actual MPPD of IDR 154 billion in the ammonia converter unit, and categorized as light, with an exposure radius of 45.78 meters and an actual MPPD of IDR 47 billion in the urea reactor unit. The hazardous area classification indicates the presence of Class I, Division 2 classified zones in several parts of the production process close to the ammonia vapor and natural gas release sources. The worst-case scenario shows a significant impact due to an explosion from the ammonia converter unit with a blast radius of up to 269 meters causing window glass breakage, and ammonia gas dispersion from the urea reactor spreading up to 10 kilometers, potentially causing respiratory issues.

Industri minyak dan gas bumi memiliki risiko tinggi terjadinya kerugian akibat kebakaran. Terdapat beberapa insiden kebakaran dan ledakan pada industri minyak yang melibatkan kebakaran pada tangki yang menampung minyak mentah. Penelitian ini bertujuan untuk menilai tingkat risiko kebakaran dan ledakan pada tangki T-32 pada fasilitas pengumpul minyak mentah Perusahaan A. Metode penelitian yang digunakan adalah melakukan analisis frekuensi terjadinya kebakaran dan ledakan dengan event tree analysis serta melakukan pemodelan konsekuensi kebakaran dan ledakan dengan software ALOHA. Setelah melakukan analisis frekuensi dan pemodelan konsekuensi, dilakukan perhitungan individual risk dan societal risk. Berdasarkan hasil pemodelan konsekuensi, Pelepasan radiasi panas dengan dampak terburuk yaitu 35 kW/m2 dapat megakibatkan kematian dengan rate 100% apabila terpajan kepada manusia. Nilai konsekuensi terburuk ini ada pada jarak 84 meter yaitu skenario tangki pecah (ukuran lubang lebih dari 250 mm) dengan kecepatan angin 20 m/s. Tidak ada tekanan yang dihasilkan dari skenario ledakan dengan dampak terburuk (7,25 psi). Nilai konsekuensi adanya tekanan 0,5 psi dalam skenario ledakan memiliki jarak terjauh yaitu 382 meter yaitu skenario tangki pecah (ukuran lubang lebih dari 250 mm) dengan kecepatan angin 1 m/s. Hasil perhitungan total individual risk dalam kejadian kebakaran pada tangki T- 32 adalah sebesar 2,44 x 10-8 dan hasil perhitungan total societal risk dalam kejadian kebakaran pada tangki T-32 adalah sebesar 4,15 x 10-7. Hasil penilaian risiko kebakaran tangki T-32 pada fasilitas tangki pengumpul minyak Perusahaan A menunjukkan bahwa risiko individu dan social masih berada dalam kategori risiko yang dapat diterima menurut kriteria penilaian risiko. Meskipun risiko dari kejadian kebakaran masih dalam batas yang dapat diterima, upaya pengendalian risiko masih perlu dilakukan agar risiko masih berada dalam batas toleransi yang dapat diterima.
Oil and gas industry has a high risk of losses due to fire. There have been several fire and explosion incidents in the oil industry involving fires in tanks containing crude oil. The objective of this research is to assess fire and explosion risk of tank T-32 at Company A's tank farm facility. The research method used is to analyze the frequency of fires and explosions using event tree analysis and modeling the consequences of fires and explosions with ALOHA software. After defining frequency and consequence model, individual risk and societal risk calculations are carried out. Based on the results of consequence modeling, the release of heat radiation with the worst impact, namely 35 kW/m2, can result in death at a rate of 100% if exposed to humans. The worst consequence value is at a distance of 84 meters from the tank rupture scenario (hole size more than 250 mm) with a wind speed of 20 m/s. No overpressure is generated from the worst-case explosion scenario (7.25 psi). The consequence value of 0.5 psi pressure in the explosion scenario has the furthest distance of 382 meters from the tank rupture scenario (hole size more than 250 mm) with a wind speed of 1 m/s. The results of calculating the total individual risk in the event of a fire in the T-32 tank are 2,44 x 10-8 and the results of calculating the total societal risk in the event of a fire in the T-32 tank are 4,15 x 10-7. The results of the T-32 tank fire risk assessment at Company A's tank farm facility show that individual and social risks are still within the acceptable risk category according to the risk assessment criteria. Even though the risk of a fire incident is still within acceptable limits, risk control efforts still need to be performed so that the risk remains within acceptable tolerance limits
