[ABSTRAK
Risiko kebakaran dan ledakan mengakibatkan kerugian terhadapkeselamatan pekerja, pencemaran lingkungan, kerusakan perangkat kerja dankredibilitas perusahaan. Fasilitas gas memiliki risiko kebakaran dan ledakankarena natural gas merupakan highly flammable dari campuran metana (utama :70-90%), etana dan sedikit senyawa lain. Oleh karena itu, sebagai dasar upayapencegahan dan pengendalian terhadap konsekuensi yang ditimbulkan dari risikokebakaran dan ledakan dengan menurunkan dampak/konsekuensi ketingkat yangbisa diterima (aceptable level) pada fasilitas pengolahan gas (separation system,gas processing system dan fuel gas system), diperlukan analisis semi-kuantitatifrisiko kebakaran dan ledakan.Teknik yang digunakan adalah melakukan analisis data sekunder (studiHAZID, studi HAZOP, Bow-tie Analysis dan simulasi PHAST). Hasil penelitianini sebagai dasar upaya mengetahui faktor-faktor dominan yang menyebabkankejadian kebakaran dan ledakan pada fasilitas pengolahan gas. Dari hasil simulasicrystal ball didapat total forecast memiliki angka 4.30 dimana jika dilihat dimatriks resiko maka berada dilevel medium risk yang berati bahwa fasilitaspengolahan gas termasuk katagori risiko masih dapat diterima. Untuk sensitivity,perubahan tekanan (16.0%), perubahan suhu (15.9%) dan kelebihan tekanan(15.8%) merupakan faktor yang paling sensitif terhadap perubahan dibandingkanfaktor-faktor lainnya. Selain itu, dapat membantu dalam menentukan rekomendasiyang tepat untuk diterapkan pada fasilitas pengolahan gas tersebut.
ABSTRACT
Risk of fire and explosion resulted in the loss of the worker safety,environmental pollution, damage to the work and credibility of the company. Gasfacility has a risk of fire and explosion because natural gas is a highly flammablemixture of methane (major: 70-90%), ethane and a bit of other compounds.Therefore, as a basis for prevention and control of the consequences arising fromthe risk of fire and explosion by reducing the impact / consequences to the levelthat can be accepted (aceptable level) with a precise cost on gas processingfacilities (separation systems, gas processing system and fuel gas system), a semiquantitativeanalysis is required the risk of fire and explosion.The technique used is to conduct a secondary data analysis (HAZID andHAZOP studies, Bow-tie Analysis and PHAST simulation). The results of thisstudy as a basis for efforts to determine the dominant factors that cause theoccurrence of fire and explosion at a gas processing facility. From the simulationresults obtained crystal ball that total forecast has the number 4.30 which whenseen in the risk matrix was at medium risk which means that the gas processingfacility including the safe category/tolerable risk. For sensitivity, pressure changes(16.0%), themperature changes (15.9%) and excess pressure (15.8%), are thefactors that are most sensitive to change than other factors. In addition, it canassist in determining the appropriate recommendations to be applied to the gasprocessing facility.;Risk of fire and explosion resulted in the loss of the worker safety,environmental pollution, damage to the work and credibility of the company.
