| Summary: | 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. |
