Abstract

To fulfill energy needs, especially of industrial and household sectors, natural gas is more desirable since Indonesia has abundant gas and it is more environmentally friendly. The better way to deliver the gas to consumers’ sites is to use a pipeline. One important consideration in pipeline construction is route selection. This study aims to obtain the optimal gas pipeline route that has minimum investment cost while being able to serve as many consumers as possible within the available gas supply and at the same time reliable (having small catastrophic risks) and being able to conserve local cultural heritage. To this end, a mathematical model has been developed and solved. As a result, among three scenarios, the best route is scenario 3, avoiding the populated area scenario. Its total investment cost is 1,331,016,661,674.34 IDR with a pipeline length of 352.95 km, a gas supply flow rate of 6.87 MMSCFD, and a total catastrophic cost of 198,039,407,500.00 IDR. The route passes 2 subdistricts with industrial areas and 71 subdistricts with household gas consumers. None of the subdistricts with cultural heritage sites are selected.
