  • Study of The Utilization of Rice Husk as an Additional Fuel in The Preheater of PT. Semen Baturaja (Persero) Tbk (Dwi Miftha Kurnia, 2014, 111 pages, 34 tabels, 5 enclosures) The cement industry is an energy intensive industry, as it absorbs electrical energy and heat are relatively large. Kiln systems are devices that absorb the amount of electrical energy and heat energy most. PT. Semen Balfour (Persero) Tbk using coal fuel as the primary fuel and Industrial Diesel Oil (IDO), which is used to start up. These energy sources are energy sources that can not be updated so that expected in the next few years will be depleted inventories. To anticipate a study done by adding fuel ie rice husk. The goal is to reduce dependence on nonrenewable energy, reduce emissions and can reduce the cost of production. The method used in this study is an experimental method to perform the addition of rice husk variation of 0%, 5%, 10%, and 15%. From the calculation of the best results in the addition of 15%, due to these variations require combustion emission is 245.395,70 kg so as to reduce production costs Rp. 871.700 ton/hour from the combustion when compared to the use of pure coal.
