Tujuan penelitian ini adalah untuk mengetahui perubahan tekanan vakum terhadap kinerja kondensor di PLTU Tanjung Jati B dengan melihat berbagai parameter seperti laju aliran masa air pendingin, temperatur air pendingin masuk dan temperatur air pendingin keluar, temperatur uap keluaran turbin tekanan rendah. Pengambilan data dengan metode observasi di PT. PLN (PERSERO) Pembangkitan Tanjung Jati B. Untuk mengetahui kinerja kondensor digunakan metode perhitungan efektivitas-NTU. Kinerja kondensor dapat dilihat dari nilai efektivitas, laju perpindahan panas, dan tekanan vakum di dalam kondensor. Pada hasil penelitian perhitungan kinerja kondensor terbaik adalah pada bulan Januari dengan efektivitas sebesar 52,128 % kemudian laju perpindahan panas sebesar 10,365MW dan bekerja pada tekanan vakum 74,35 mbar absolut. terjadi ketika beban antara 90 % sampai 100 %.”Kata kunci : Kondensor, perubahan beban, tekanan vakum, efektivitas kondensor
