CAPITAL TURBINES INDONESIA PLTU GALANG BATANG 2 X 15 MW BINTAN}, year={2017}, url={http://156.67.221.169/333/}, abstract={Galang Batang Bintan Steam Power Plant is Independent Power Producer has two generating units which is the capacity of each unit is 15 MW so, the total capacity of electric power produce amount 30 MW. This Steam Power Plant uses coal as its fuel. Water is a potential source of energy as a main component to generate steam in steam power plant. The performance of Reverse Osmosis is a tool for producing boiler feed water is filled continuously. The problem that often happens in Reverse Osmosis is membrane blocked. In this research, the calculation of Reverse Osmosis efficiency using Reverse Osmosis operational data retrieval method, interview method in water treatment plant and literature studies method. From the result of calculation got requirement of feed water around 3,2 m3/hr with the product result of Flow Reverse Osmosis around 7,5 m3/hr. In addition to the calculation data, there are 4 factors that affect the efficiency of Reverse Osmosis are the factor of impurities on the membrane, the factor of temperature, the factor of pressure and the factor of chemical.} }
