Abstract
Unjuk kerja suatu Pembangkit Listrik Tenaga Gas dan Uap (PLTGU) sangat diperlukan untuk mengetahui keadaan terkini PLTGU tersebut. Parameter unjuk kerja mesin-mesin pada PLTGU sangat bergantung banyak pada bahan bakar yang digunakan oleh Turbin Gas. Pada Tugas Akhir ini akan diketahui perbandingan unjuk kerja Turbin Gas menggunakan bahan bakar Natural Gas dengan Turbin Gas berbahan bakar HSD Oil. Pertimbangan penggunaan bahan bakar pada Turbin Gas merupakan hal yang sangat penting untuk diperhatikan dalam operasi PLTGU. Parameter utama penggunaan bahan bakar secara teknik adalah biaya bahan bakar dan specific fuels consumption (SFC). Menurut statistik ketenagalistrikan yang dirilis oleh Kementerian ESDM (Energi dan Sumber Daya Mineral) tahun 2014 menunjukkan bahwa Turbin Gas pada PLTGU di Indonesia menggunakan bahan bakar Natural Gas dan HSD Oil dengan jumlah berturut-turut adalah 267.089,68 mmscf dan 1.078.644,6 kilo liter. Oleh karena itu, pada Tugas Akhir iniakan diketahui unjuk kerja Turbin Gas mana yang paling optimum dan mempunyai biaya bahan bakar yang ekonomis beserta specific fuels consumption yang paling rendah. Setelah dilakukan penelitian, dapat diambil kesimpulan bahwa Turbin Gas yang menggunakan Natural Gas sebagai v bahan bakar operasi mempunyai unjuk kerja yang lebih optimum dan lebih baik daripada Turbin Gas yang beroperasi menggunakan bahan bakar HSD Oil. Di samping itu, nilai specific fuels consumption Turbin Gas berbahan bakar Natural Gas juga lebih rendah daripada Turbin Gas berbahan bakar HSD Oil. Dari segi biaya bahan bakar, Turbin Gas berbahan bakar Natural Gas mempunyai biaya bahan bakar yang lebih rendah (ekonomis) daripada Turbin Gas berbahan bakar HSD Oil yang mempunyai biaya bahan bakar yang relatif tinggi (mahal).

Performance of gas and vapour power generation must be known to observe newest condition from its power generation. Machine performances from its power generation parameter depends from its fuels used by Gas Turbine. In this final project, performance comparisons between Gas Turbine fueled by Natural Gas and HSD Oil will be known. Fuel used consideration factor on Gas Turbine is the most important thing to become attention of gas and vapour power generation operations. First parameter fuels consideration in engineering is cost of fuels and specific fuels consumption (SFC). According to electricity statistic that released by ministry of energy and mineral resources in the year 2014 shown that Gas Turbine on gas and vapour power generation in Indonesia use 267.089,68 mmscf Natural Gas and 1.078.644,6 kilo liter HSD Oil. Because of that, this final project will show the best performance of Gas Turbine between Gas Turbine fueled by Natural Gas and Gas Turbine fueled by HSD Oil. The lower fuel costs and specific fuels consumption of Gas Turbine will be shown too. After the research is done, it can be taken a conclusion that Gas Turbine fueled by Natural Gas has optimum performances and better than Gas Turbine fueled by HSD Oil. In vii the other hand, the value of specific fuels consumption of Gas Turbin fueled by Natural Gas is lowest than Gas Turbine fueled by HSD Oil. From cost fuels side, Gas Turbine fueled by Natural Gas has low fuel costs (economical) than Gas Turbine fueled by HSD Oil that has high fuel costs (expensive).
