Falih}, title ={Analisis Pengaruh Temperature Ambient Terhadap Nilai Energi dan Eksergi PLTG di Unit 2.1 dan Unit 2.2 PLTGU Muara Karang}, year={2019}, url={http://156.67.221.169/596/}, abstract={ANALYSIS OF THE EFFECT OF AMBIENT TEMPERATURE TO THE ENERGY VALUE AND EXERGY OF PLTG IN UNIT 2.1 AND UNIT 2.2 PLTGU MUARA KARANG .Most of the learning about improving the performance of PLTGU components and the design of current generating machines based on thermodynamic law I is related to energy without considering the II law of thermodynamics. Therefore, the purpose of this study is to determine the comparison of energy efficiency and exergy values in the Muara Karang gas power plant Unit 2.1 and Unit 2.2 turbine with the comparison of its ambient temperature to determine extermination that occurs in the PLTG system so that by knowing extermination of exergy the potential for loss can be identified. and improvements can be made to the PLTG system. This study discusses the influence of ambient temperature and air pressure to determine the resulting changes in performance. The method used is the exergy calculation method which is influenced by enthalpy, entropy, and energy equilibrium. From the results of the analysis obtained in April, May, and June that for energy efficiency experienced the highest point in the morning and the lowest point during the day, as well as the value of energy efficiency, changes in energy efficiency and exergy caused by ambient air temperature which changes every time. The study results also show that the components that have great potential for improvement are the Combustion Room with the highest Exergy destructions in April for GT 2.1 of 63,45% and GT 2.2 of 57,72%, in May for GT 2.1 of 57,30% and GT 2.2 was 57,71%, and in June for GT 2.1 it was 66,65% and GT 2.2 was 57,67%, thus providing a good effect on changes in the efficiency of a plant.} }
