POTENTIAL COMPARISON OF THE UTILIZATION OF KALIANDRA (CALLIANDRA CALOTHYRSUS) AND GAMAL (GLIRICIDIA SEPIUM) AS CO-FIRING TO MEET FUEL NEEDS FOR PLTU SUDIMORO PACITAN

Abstract

One of the efforts made by the government to accelerate the national energy mix is to apply co-firing technology to power plants that still use fossil fuels. The use of co-firing can reduce GHK emissions (greenhouse gas) from the use of fossil fuels. PT PJB UBJ UM Jatim 1, located in Pacitan, has a target to do co-firing with biomass substitution. Kaliandra wood and Gamal wood are research objects as biomass that have the potential as fuel substitution for co-firing technology. The purpose of this study is to calculate the energy potential of Kaliandra and Gamal, conduct SFC analysis, analysis of production costs, and calculate the emissions issued by the Kaliandra and Gamal Biomass in the co-Firing. The method carried out in this study is in the form of quantitative methods. The results showed that to produce power for 1 hour with a total fuel of 182,800 kg, the generator when operating using Kaliandra fuel 10% produced a power of 287,981 KWH which was higher than the use of other types of materials. Power plants operating using Kaliandra Co-Firing fuel to produce 1 kW power for 1 hour have the cost of electricity production, SFC, and CO2 emissions in the order of Rp 1,379.53/kWh, 0.635 kg/kWh, 1.15 kgco2/kWh lower compared to when operating using other types of fuel. To produce 1 kWh power plant that operates using Co-Firing Kaliandra 10% consumes less energy, low cost, and CO₂ emissions are lower when compared to using other types of fuel.
