Susunan peralatan proses dan bangunan dapat memiliki dampak besar padaefisiensi sebuah pabrik. Dalam upaya untuk memaksimalkan efisiensi pabrik,desain tata letak pabrik harus memfasilitasi proses produksi, meminimalkan alurproses material dan biaya operasi, serta tetap harus memenuhi aspek keamanan dankeselamatan operasi. Penelitian ini mengambil objek penelitian pada sebuahStasiun Kompresi Gas yang akan dilakukan optimasi susunan tata letak peralatandengan model MINLP dengan Algoritma Branch and Bound untuk pemenuhanjarak aman, pertimbangan arah angin untuk memposisikan flare stack denganmeminimumkan jarak aliran material. Hasil penelitan menunjukkan susunan tata letak hasil optimasi mengalamiperubahan dibanding tata letak existing, dengan pemenuhan seluruh jarak amanantar fasilitas, posisi flare stack yang sesuai, dan efisiensi biaya perpipaan areaproses sebesar 21,6. ...... The arrangement of process equipment and building can have a big impact onefficiency of a factory. In an effort to maximize plant efficiency, the plant's layoutdesign should facilitate the production process, minimize the material process flowand operating costs, and still meet the safety and security aspects of the operation. The object of this research is a Gas Compression Station which the equipmentlayout arrangement will be optimized with MINLP model with Branch and BoundAlgorithm for the fulfillment of safe distance, wind direction consideration toposition flare stack by minimizing material flow distance. The results showed that the layout of the optimization result changed compared tothe reference layout, with the fulfillment of all safe distance between facilities, theappropriate flare stack position, and the cost efficiency of pipeline process area of 21,6.

[ABSTRAK
Tesis ini membahas bagaimana memanfaatkan gas suar bakar yang ada di Platform X untuk dapat menjadi suatu yang bernilai ekonomis. Gas suar bakar yang ada di Platform X selama ini hanya dibakar. Penelitian ini dimulai dengan menganalisa komposisi gas suar bakar yang ada di Platform X agar dapat ditentukan proses seperti apa yang tepat untuk mengolah gas suar bakar menjadi gas jual. Dari segi analisis teknis, proses Kompresi Gas merupakan pilihan tepat untuk mengolah gas suar bakar menjadi gas jual. Dilihat dari analisa komposisi gas suar bakar yang rendah gas asam membuatnya tidak perlu pengolahan lanjutan. Gas suar bakar dapat dikompresikan untuk dialirkan ke aliran gas yang masuk ke fasilitas gas eksport untuk diproses agar sesuai dengan spesifikasi gas eksport. Fasilitas gas eksport di Platform X didesain untuk menampung gas 175 MMSCFD dimana produksi saat ini sebesar 125 MMSCFD sehingga masih mampu menampung masukan gas. Dari hasil analisa ekonomi investasi ini dinilai layak dilakukan, dengan nilai WACC 23,89% dan IRR 28,88%.

ABSTRACT
The focus of this study is how to utilize Flare Gas in Platform X into valuable products. At all this time, the Flare Gas in Platform X is just burn in to flaring tip. This study is starting with analyze the gas composition in Platform X so it can specified what the right method to utilize the Flare Gas in Platform X into sales gas. From technical analysis, the Gas Compression is a perfect method to treatment Flare gas into sales gas. From the composition of gas analysis this gas has lower sour gas contents makes it unnecessary further treatment. Flare gas can be compressed to flow into the gas stream entering the facility to export gas to be processed in order to conform to the specifications of the gas export. Platform X Gas export facilities designed to handle 175 MMSCFD of gas so it still able to handle input gas. From the results of the economic analysis of investments is considered feasible, the WACC value of 23.89% and 28.88% IRR.;The focus of this study is how to utilize Flare Gas in Platform X into valuable products.
