Abstract

Pada saat ini PT. Indonesia Power UPJP Kamojang mengoperasikan PLTP dengan kapasitas total sebesar 375 MW, untuk penelitian Tugas Akhir berikut menggunakan unit II pada PLTP Kamojang. Agar memperoleh kapasitas listrik yang optimum maka diperlukan efisiensi yang baik dari proses produksi dengan menganalisa efisiensi thermal dan eksergi serta menghitung biaya kerugian eksergi berdasarkan termoekonomi. Berdasarkan perhitungan yang telah dilakukan, maka didapatkan efisiensi thermal sistem sebesar 19,41%. Dengan eksergi loss terbesar dan terendah pada komponen turbin dan cooling tower sehingga biaya rugi eksergi pada cooling tower bernilai kecil sebesar 7.394.034,76 Rp/bln dan biaya rugi eksergi pada turbin sebesar 252.766.682,24 Rp/bln, untuk nilai efisiensi eksergi yang terbesar pada komponen separator yaitu 99,47% sedangkan efisiensi eksergi sistemnya sebesar 47,06%. Dari hasil tersebut dapat diketahui bahwa efisiensi sistem dipengaruhi oleh performansi masing-masing komponen, dan banyaknya eksergi yang hilang dalam komponen-komponen tersebut. Sedangkan saran yang bisa dilakukan untuk pembangkit listrik yang telah diteliti adalah perlu dilakukannya maintenance secara rutin terhadap komponen turbin serta kondensor dikarenakan memiliki eksergi loss yang cukup tinggi yang akan. =========================================================== At this time PT. Indonesia Power UPJP Kamojang operates a PLTP with a total capacity of 375 MW, for the following Final Project research using unit II of the Kamojang PLTP. In order to obtain optimum electrical capacity, good efficiency of the production process is required by analyzing thermal and exothermal efficiency and calculating the cost of exergy losses based on thermodynamics. Based on the calculations that have been made, the thermal efficiency of the system is 19.41%. With the exergy of the biggest and lowest losses in the turbine and cooling tower components so that the cost of exergy loss on the cooling tower is of small value of 7,394,034.76 Rp / month and the cost of exergy loss on the turbine is 252,766,682.24 Rp / month, for the value of exergy efficiency the largest in the separator component is 99.47% while the system's execution efficiency is 47.06%. From these results can be seen that the efficiency of the system is influenced by the performance of each component, and the number of missing allergy in these components. While the advice that can be done for the power plant that has been investigated is the need for routine maintenance of the components of the turbine and condenser because it has a high enough exergy loss that will affect the efficiency of the system.
