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.
This study assess the consequences of the chemical release from the pressurized Liquefied Petroleum Gas (LPG) storage tank at PT. LMI. This study is kuantitative. Simulation of release using ALOHA (Areal Locations of Hazardous Athmospheres) software based on primary and secondary datas on the normal operation. ALOHA give result in a distance range of dispersion, fire and explosion. Each distance range is classified into three categories: red, orange and yellow based on the level of severity. These study's result is indicate that schools, medical clinic, factories, and homes around PT. LMI being the high-risk population affected by the release of chemicals from the LPG storage tank.

Tesis ini membahas mengenai analisa risiko ledakan yang berasal dari bahan kimia di PTZ, berfokus pada ledakan yang berjenis Vapour Cloud Explosion (VCE) akibat adanyakebocoran pipa yang terhubung dengan empat buah tangki penimbunan LPG berjenisspherical. Analisa ini menggunakan pendekatan Computational Fluid Dynamic tigadimensi yang diproses oleh perangkat lunak FLACS. Tesis ini adalah penelitian kualitatifdengan desain deskriptif dan menggunakan metode QRA (Qualitative Risk Assessment)dalam menganalisa risiko ledakan. Dapat diketahui dari hasil penelitian bahwa tekananyang dihasilkan dari ledakan VCE dapat berpotensi menghancurkan fasilitas yang beradadi PT Z seperti bangunan perkantoran, gudang, dan area sekitar diluar fasilitas PT Z akibattekanan tertinggi yang dihasilkan dari ledakan sebesar 0,33 bar. Dampak blast wave dapatdirasakan hingga radius . PT Z disarankan untuk selalu merawat fasilitas, teknologikeselamatan, dan peralatan keselamatan dengan melakukan audit rutin sebagai bentukupaya pencegahan bahaya ledakan.Kata kunci:FLACS, Ledakan, VCE, LPG, QRA

Abstrak:
Perusahaan minyak dan gas adalah salah satu instansi yang berisiko tinggi terjadinya ledakan atau kebakaran (ILO, 1991). Ledakan dan kebakaran tersebut dapat digolongkan ke dalam kategori bahaya besar, karena dapat menimbulkan kerugian besar dalam waktu yang singkat. Penyebabnya dapat disebabkan oleh banyak variabel tergantung dari bentuk fisik suatu material (padat, cair atau gas), sifat fisik (kapasitas panas, tekanan uap, pembakaran panas, dll) serta kereaktifannya. Kondisi ini sebenarnya dapat diminimalkan dengan upaya pencegahan dan pengendalian risiko, salah satunya dengan menganalisis konsekuensi dispersi gas, ledakan dan kebakaran yang diakibatkan oleh kebocoran tangki penyimpanan LPG bermuatan 30 ton tahun 2012 dengan menggunakan metode penelitian kuantitatif deskriptif. Pada penelitian ini penulis menggunakan 3 skenario terpisah antara propana dan butana yaitu vapor cloud, jet fire dan BLEVE, karena ketiga skenario ini memungkinkan untuk terjadinya kebocoran gas. Peneliti melihat kejadian mulai dari yang terkecil hingga terbesar agar efek / dampak yang ditimbulkan dapat diantisipasi. Analisis ini menggunakan piranti lunak ALOHA (Areal Locations Of Hazardous Atmospheres), dimana ALOHA dapat memprediksikan seberapa jauh penyebaran dari setiap skenario yang dibuat.
Oil and gas companies are among the high-risk establishments explosion or fire (ILO, 1991). Explosions and fires can be classified into the category of great danger, because it may cause a big loss in a short time. The cause can be caused by many variables depending on the physical form of a material (solid, liquid or gas), physical properties (heat capacity, vapor pressure, burning heat, etc.) as well as its reactivity. This condition can actually be minimized by preventing and controlling risk, example analyzing the consequences of gas dispersion, fire and explosion caused by leakage of LPG storage tanks loaded with 30 tons in 2012 by using the descriptive quantitative research methods. In this study the authors used three separate scenarios namely vapor cloud, jet fire and BLEVE for each propane and butane, because these are the three possible scenarios for gas release. The purpose is to analyse all these events ranging from smallest to largest damage order so that effect / impact can be anticipated. This analysis uses software ALOHA (Areal Locations of Hazardous Atmospheres), where ALOHA can predict how far the spread and the impact of all the scenarios.
