ABSTRAKRisiko kebakaran dan ledakan mengakibatkan kerugian terhadap
keselamatan pekerja, pencemaran lingkungan, kerusakan perangkat kerja dan
kredibilitas perusahaan. Fasilitas gas memiliki risiko kebakaran dan ledakan
karena natural gas merupakan highly flammable dari campuran metana (utama :
70-90%), etana dan sedikit senyawa lain. Oleh karena itu, sebagai dasar upaya
pencegahan dan pengendalian terhadap konsekuensi yang ditimbulkan dari risiko
kebakaran dan ledakan dengan menurunkan dampak/konsekuensi ketingkat yang
bisa diterima (aceptable level) pada fasilitas pengolahan gas (separation system,
gas processing system dan fuel gas system), diperlukan analisis semi-kuantitatif
risiko kebakaran dan ledakan.
Teknik yang digunakan adalah melakukan analisis data sekunder (studi
HAZID, studi HAZOP, Bow-tie Analysis dan simulasi PHAST). Hasil penelitian
ini sebagai dasar upaya mengetahui faktor-faktor dominan yang menyebabkan
kejadian kebakaran dan ledakan pada fasilitas pengolahan gas. Dari hasil simulasi
crystal ball didapat total forecast memiliki angka 4.30 dimana jika dilihat di
matriks resiko maka berada dilevel medium risk yang berati bahwa fasilitas
pengolahan 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 dibandingkan
faktor-faktor lainnya. Selain itu, dapat membantu dalam menentukan rekomendasi
yang tepat untuk diterapkan pada fasilitas pengolahan gas tersebut.
ABSTRACTRisk of fire and explosion resulted in the loss of the worker safety,
environmental pollution, damage to the work and credibility of the company. Gas
facility has a risk of fire and explosion because natural gas is a highly flammable
mixture of methane (major: 70-90%), ethane and a bit of other compounds.
Therefore, as a basis for prevention and control of the consequences arising from
the risk of fire and explosion by reducing the impact / consequences to the level
that can be accepted (aceptable level) with a precise cost on gas processing
facilities (separation systems, gas processing system and fuel gas system), a semiquantitative
analysis is required the risk of fire and explosion.
The technique used is to conduct a secondary data analysis (HAZID and
HAZOP studies, Bow-tie Analysis and PHAST simulation). The results of this
study as a basis for efforts to determine the dominant factors that cause the
occurrence of fire and explosion at a gas processing facility. From the simulation
results obtained crystal ball that total forecast has the number 4.30 which when
seen in the risk matrix was at medium risk which means that the gas processing
facility including the safe category/tolerable risk. For sensitivity, pressure changes
(16.0%), themperature changes (15.9%) and excess pressure (15.8%), are the
factors that are most sensitive to change than other factors. In addition, it can
assist in determining the appropriate recommendations to be applied to the gas
processing facility.;Risk of fire and explosion resulted in the loss of the worker safety,
