ANALISA PENGARUH KUALITAS BATUBARA TERHADAP BIAYA PEMBANGKITAN (STUDI KASUS DI PLTU REMBANG)
ABSTRACT: Coalisone of the
sourcesof energythat are widely usedinpower generation. Indonesiancoal
productionas much as254milliontons in 2009as much as75% is exported, while the
remaining25% for domestic consumption. Since much ofhigh-gradecoal(coal
highrange) wereexportedout of the countrymakes theplantsin
Indonesiawereoperating usingwith alow qualitycoal. The results ofthe analysis
carried outinPLTU RembangofSeptember-November 2013can be concludedthatthe lower
thecalorific valueof coalisusedthe higher themass flow rateof coal,
thesteammass flow rateisrelativelythe same. The higherthe load, the coalmass
flow rateis also higher,the specificfuelconsumption(kg /kWh) was
decrease,theheatratewas decrease. However,the thermalefficiencywas increase.
When theload of180MWto 250MWmoreefficientuseof coalcomposition100% LRC. Ata

theaverage value ofthe price ofproduction, moreefficientuseof
