Plastic waste and organic waste in the form of biomass are possible to produce alternative energy to drive turbines in power plants by turning them on with coal in the co-firing process. This study has purpose analyzing the behavior of coal combustion with a mixture of EFB and plastic compared to the pure coal using the TGA-DSC method. Test were carried out under atmospheric conditions. Addition of biomass in mixture lower the ignition temperature (Tig) of coal. The sample with lowest Tig is C1 (Coal + EFB) with value of 257.8°C. Mixture with biomass decreasing the reactivity of coal with value Tmax is increase, C2 (Coal + EFB + PET bottle) has highest Tmax with value of 423.1°C. C2 also has highest Tbo with value of 622.5°C. From Tmax and Tbo, it showed that addition of biomass decreases the self-burning tendency and prolong the combustion
