Abstract
Dari parameter operasi Gas Turbine, pada pola pembebanan yang sama, beban yang tercapai saat temperature udara lebih rendah cenderung lebih tinggi. Terdapat beberapa penelitian yang membahas mengenai pengaruh temperature udara inlet kompresor terhadap power output gas turbine. Selain penelitian mengenai efek temperature udara inlet kompresor terhadap power output GT, penelitian mengenai pemanfaatan teknologi untuk menurunkan temperature udara inlet kompresor juga sudah banyak dilakukan, diantaranya pemanfaatan teknologi eva-cooler system, fog spray system dan mechanical chiller. Studi kasus ini bertujuan untuk mengetahui efek pemanfaatan teknologi eva-cooler system, fog-spray system dan mechanical chiller terhadap performa GT UP Muara Tawar, dimana sebelumnya studi kasus tersebut belum pernah dilakukan. Studi kasus ini membandingkan performa GT yang diperoleh dari simulasi Cycle-Tempo 5.0, antara kondisi existing dengan kondisi yang telah dimodifikasi menggunakan eva-cooler system, fog spray system dan mechanical chiller. Simulasi pada kondisi existing dilakukan dengan menggunakan data heat balance dan data operasi lainnya. Dari studi kasus diperoleh hasil, kenaikan power output GT yang paling maksimum diperoleh dari pemanfaatan mechanical chiller. Dimana dapat meningkatkan power output rata-rata sebesar 11.75 MW atau sebesar 9.78% untuk setiap penurunan 1 oC temperatur udara ambient. Sedangkan heat rate turun sebesar 105.13 kCal/kWh, atau sebesar 3.81%.

From the operating parameters of the Gas Turbine, the load achieved when the air temperature is lower tends to be higher. There are several studies that discuss the effect of compressor inlet air temperature on gas turbine power output. In addition, research on the use of technology to reduce compressor inlet air temperature has also been widely done, including the use of eva-cooler system technology, fog spray system and mechanical chiller. This case study aims to find out the effect of utilizing eva-cooler system technology, fog-spray system and mechanical chiller on the performance of GT UP Muara Tawar, where previous case studies have never been done. This case study was conduct by compared GT performance obtained from cycle-tempo 5.0 simulation, between existing conditions and that have been modified using eva-cooler system, fog spray system and mechanical chiller. Simulations on existing conditions are carried out using heat balance datas and other operating datas. From the case study obtained results, the maximum increase in GT power output is obtained from the utilization of mechanical chiller. It can increase the average power output by 11.75 MW or by 9.78% for every 1 oC drop in ambient air temperature. While the heat rate decreased by 105.13 kCal / kWh, or by 3.81%.
