Transportation and pollution has become a severe problem in many big cities in developing countries, include Indonesia especially in Indonesia’s capital city, Jakarta. Over usage of petroleum, pollution and heavy traffic problem in Jakarta has become a more complicated case in the daily life. Meanwhile, compressed natural gas (CNG) is a clean burning, high energy, alternative energy source that enables us to safely continue to build on and improve our current lifestyle in the future. Transjakarta Busway is currently preparing to use compressed natural gas for powering the busway and it will need to define the best pipeline route from the existing main gas source to the CNG Station by considering cost, safety, social conflict, etc. The objective of this research is to determine the best route for a gas transmission pipeline network that considers various criteria for minimizing adverse. The methods of this research is based on multi criteria decision making by implementing GIS model technology refers to spatial analyst and network analyst that will produce possibility alternative routes. Having established alternative routes, each criterion and alternatives should be evaluated and weighted using pairwise comparison in term of analytical hierarchy process (AHP) to identify the best route for a gas transmission pipeline into the most preferred route. The model is concerned only with distribution lines, in areas that are already largely urbanized or industrialized. The distribution pipes will be installed under the shoulder of existing roadways and beside existing utilities. So no land needs to be purchased, and no one will be displaced. There will be some very temporary (up to one day) disruption to businesses, residents, and other facilities along the roadsides and utilities as the pipe construction, dig, bury, and test the piping. This is unavoidable, but it has standard operating procedures and various prevention and mitigation measures in place, based upon long experiences, to minimize these disruptions. This model has been applied in Transjakarta Busway Corridor VII. It was found that the best CNG pipeline route was in Kramat Jati.
