Abstract:
Indonesian government launched Fast Track Program Phase-1 in 2009 to increase national electricity ratio
by installing 35 coal power generations with total capacity 10,000 Mega Watt. However only 25 coal power
generations had been installed by now, spread all over Indonesia. Coal necessities were supplied by 14
domestic coal mining companies. There are two factors that affect the price of coal i.e : distance and unit
price. Distance between supplier and coal power generation would determine the transportation cost while
unit price would determine the price of procurement. The aim of this research is to minimize total price of
coal by optimizing the distance and unit price (USD/Ton), allocating the coal necessities and scheduling the
delivery. The optimization would be simulated using software What’sBest. By this simulation, 24 power
plants were suggested to change their existing suppliers, while only one power plant was fitted. This change
could reduce USD 27 Million/year fo
r total price of coal.
