The use of sugar-cane waste (Bagasse) energy as substitution of fossil-fuel energy in Krebet Sugar Factory, East Java, Indonesia

Abstract

Industry is one form of economic activities that process raw material and/or utilize industry resource to produce product with a higher value or benefits. Rapid growth of industrial activities an increase community’s welfare. While on other side, industrial development can increase the value of CO2 emission that can influence global warming. Krebet Sugar Factory in one of the largest sugar industries in Indonesia and so far, still using fossil fuels (gasoline, diesel, residue oil) as energy resource in production process. Based on 2011 National Greenhouse Gas Emission Reduction Action Plan, CO2 emission reduction’s target in Indonesia, especially in industrial sector for year 2020 is 0,001 Gton CO2 (Scenario 26%). One of mitigation action that can be done to support CO2 emission reduction is using alternative energy resource/fuel bagasse. The aim of this research is to evaluate utilization of factory waste for alternative energy resource/fuel (bagasse). Krebet Sugar Factory have production capacity of 840 ton/day. Average of Electricity resource provided by PT. PLN is 26,40 KVA/month, while the electricity average usage provided by Krebet Sugar Factory’s power plant is 4.320 KVA/month and Krebet Sugar Factory Fuel’s consumption for one year is 19.500 ton. Based on production data, average bagasse production of Krebet Sugar Factory is 420.533,34 ton so can produce energy value in the amount of 4.878,19 Terajoule that can be used as an alternative energy resource.
