Paper Title
Quantitative Risk Assessment of City Gas Network at DEPOK, West Java

Abstract
A City Gas Network has, commonly, a potential in an accident of fire and explosion risks. To date, the extend of risk of city gas network located in Depok, west Java hasn’t yet be taken into account.The aim of the research is to count the risk by methodof quantitative risk assessment. This assessment is performed by determination of the failure frequency, by consequence analysis using ALOHA Software, and by evaluating the risk magnitude that is categorizedaccording to the UK Health and Safety Executive (UK-HSE) standard criteria. So, the gas network risk mitigation can be recommended accurately based on the cost-benefit analysis with the disproportion factor less than or equal to 10.The results from the risk evaluationshowed that the individual risk in each of 28 nodes in thegas pipeline network observed in Depok is categorized wholly in category II (i.e tolerable if ALARP).Furthermorethe result of societal risk evaluation according to UK-HSE F-N Curve is also confirmed in category II. So,in order to achieve ALARP, it isrecommended, especially, to prevent the possiblities of leaked gas indoor accumulation bythe installation of rooftop turbine ventilator at Metering Regulating Station (node 3). The other of gas station, the periodic patrols and visual inspections should be carried out for all pipeline nodes. Index Terms- Node, Individual Risk, Societal Risk, ALARP
