Abstrak

Heat rate mempunyai peranan yang sangat penting pada pembangkit listrik.
Heatrate merupakan ukuran dari thermal sebagai jumlah dari energi bahan
bakar yang dibutuhkan untuk menghasilkan sejumlah energi listrik.Satuan
heatrate yaitu kJ/kWh. Penelitian ini bertujuan untuk mengetahui nilai
turbineheatrate pada turbin uap berdasarkan performance test. Pengambilan
data dilakukan dengan metode observasi di PT. INDONESIA POWER UJP
BANTEN 3 LONTAR (PLTU) pada pembangkit unit 1. Untuk mengetahui nilai
turbine heatrate pada turbin uap digunakan metode perhitungan berdasarkan
massa uap “steam†dan energi dalam “entalphy†yang masuk dan keluar turbin
dengan daya keluaran generator (output generator). Turbine heatrate berbanding

terbalik dengan efisiensi, yang artinya semakin kecil nilai turbine
heatrate maka semakin baik efisiensi pembangkit tersebut, sebaliknya semakin
tinggi nilai turbine heatrate maka efisiensi pembangkit tersebut buruk. Hasil
Analisa yang didapat pada turbine heatrate berdasarkan performance test unit
1dengan nilai terendah (terbaik) yaitu pada bulan Januari dengan nilai 8252.61
kJ/kWh, dan nilai tertinggi (terburuk) yaitu pada bulan Maret dengan nilai
8911.99 kJ/kWh. Kenaikan dan penurunan turbin heatrate tidak begitu
signifikan.
