Abstract

Penggunaan sumber energi yang kurang efisien menyebabkan terjadinya pemborosan energi. Sektor industri merupakan penggunaan sumber energi terbesar, sehingga terjadinya pemborosan energi juga besar. Salah satunya yaitu di PLTU milik PT. Jawa Power Unit 5. Untuk mengurangi pemborosan energi, yang harus diminimalkan yaitu heat losses. Heat losses dapat diketahui dengan melakukan audit energi yang bertujuan mengetahui peralatan yang mengalami pemborosan energi. Berdasarkan hasil audit energi dan representasi dengan diagram sankey pada kondisi beban 100%, jumlah panas yang masuk sebesar 1.939.557,49 kW, unjuk kerja boiler sebesar 1.225.724,66 kW dengan nilai efisiensi boiler sebesar 63,19%, unjuk kerja turbin uap sebesar 690.432,22 kW dengan nilai efisiensi 53,92%, unjuk kerja pompa sebesar 18.667,97 kW dengan nilai efisiensi 33,81%, unjuk kerja kondenser 341.415,75 kW, dan nilai efisiensi thermal sebesar 34,63%. Pemborosan energi terbesar pada boiler dengan losses sebesar 713.951,11 kW, losses pada turbin sebesar 26.594,1 kW, losses pada pompa sebesar 4.013,71 kW. Rekomendasi yang dapat diterapkan Penambahan air heater didapatkan nilai ekonomis sebesar Rp. 5.577.365/ jam ============================================================================================================= The use of energy sources that are less efficient cause energy waste. The industrial sector is the largest energy source, so that energy wastage is also great. One of them is in the power plant owned by PT. Java Power Unit 5. To reduce energy waste, which must be minimized, namely heat losses. Heat losses can be determined by performing an energy audit aimed to know the equipment experiencing energy waste. Based on the results of an energy audit and representations with Sankey diagram at 100% load conditions, the amount of heat entering 1.939.557,49 kW boiler performance with a value of 1.225.724,66 kW boiler efficiency by 63.19%, the performance of the turbine amounting to 690.432,22 kW steam with the efficiency of 53.92%, the performance of 18.667,97 kW pump with an efficiency of 33.81%, the performance of the condenser 341.415,75 kW, and the value of the thermal efficiency of 34,63%. Biggest energy waste in boilers with losses amounting to 713.951,11 kW boiler losses amounted to 26594.1 kW turbine, the losses amounted to 4013.71 kW pump. Recommendations that can be applied Additions air heater obtained the economic value of Rp. 5.577.365/ hour
