CNS is one of the plantation wastes that can be used as alternative fuel which can be mixed with LRC. The research aims to obtain thermal and chemical characteristics of LRC – CNS mixing and the impact of adding CNS into LRC on combustion characterization. An experimental test was conducted to obtain thermal characteristics by using proximate and ultimate analysis based on ASTM standard. Combustion characteristics are obtained by using differential thermal analysis (DTA) and thermal gravimetry analysis (TGA) by using air as an oxidant. The Composition of CNS mixtures with LRC are 10, 30 and 50 respectively. The result of CNS mixed with LRC generalized improves the quality of the fuel mixture by the increase combustion reactivity, and this has an impact on increasing differential internal energy. The optimum addition of CNS into LRC was obtained of 10%.
