Abstract

The use of natural gas in a form of CNG in Indonesia still needs to be developed. Padang is one of the cities in Indonesia that requires CNG for transportation needs, mainly for public transportation. However, there is no natural gas in West Sumatra. The nearest source of natural gas from the area is located in Duri. It requires logistic, technical, and economic reviews to facilitate the natural gas in order to fullfil the transportaion essensials. The natural gas needed for public transportation gas is approximately 11,152 lsp (litre on premium). The logistic calculation of CNG delivery will require two trucks with the capacity of 5,790 lsp each, from Duri to Padang. The total of SPBG (Natural Gas Filling Station) in Padang is designated by the capacity and demand in Padang by the total of two. Each SPBG will receive one truck of CNG per day. The technical design calculation requires to use a process software. For the technical design aspect in Duri, the compressor station has two units of compressors to compress the gas from 2 bar until 200 bars. The power of each compressor is 51.01 kW for first and 55.08 kW for second. Moreover, the compressor requires two units of heat exchanger for intercooling gas and four units of pressure cylinder which has 10 tubes. For the technical design aspect in Padang, one SPBG has three storage tanks with a volume of 1.96 m3, the priority panel is one set, and dispenser is three units of vehicle. The results are feasible to do with a government funding scheme of 30% from CAPEX, the feasible gas price is Rp 5,200 / lsp. The comparison from natural gas price and subsidicial gasoline (premium) price is Rp 187,500 / month if consume 150 L / month. With this price, the Net Present Value of the study is Rp 2,651,172,954, Internal Rate of Return has 9.92% and Payback Period for eight years.
