[ABSTRAK
Pengelolaan gas bumi merupakan isu yang penting terkait permintaan dan hargabagi kepentingan negara maupun konsumen. Penelitian ini bertujuan melakukanoptimisasi terhadap fungsi social welfare mewakili kepentingan konsumen danfungsi netback produsen mewakili kepentingan negara. Obyek penelitian ini adalahpasar gas bumi Jawa Bagian Barat dengan permintaan terbesar di Indonesia daninfrastruktur terintegrasi. Optimisasi multi obyektif digunakan untuk memperolehtitik optimum kedua fungsi. Formula harga wholesale gas bumi pada titik optimumdisusun sebagai fungsi linier terhadap harga minyak bumi dengan slope α dankonstanta k. Nilai α diperoleh dengan rentang 0,1079 ? 0,1589 dengan k padarentang 3,7 ? 5,38.;

ABSTRACT

Natural gas utilization is an important issue related to the demand and prices

for the benefit of country and consumers. This study aims to optimize social welfare

represents the interests of consumer and producer netback representing the interests

of country. The scope of this research is the natural gas market in Western Java area

having the biggest demand and integrated infrastructure. Multi-objective

optimization is used to obtain the optimum value of both functions. Wholesale price

formula of natural gas at the optimum value is structured as a linear function of the

price of crude oil with slope α and constant k. The values of α obtained in the range

of 0.1079 to 0.1589 with k in the range of 3.7 to 5.38, Natural gas utilization is an important issue related to the demand and prices
