It needs to become a source of renewable energy raw materials derived from biomass, through revegetation reclamation activities. Therefore, this study aims to analyze the differences in the quality of the wood pellets derived from distinguished raw materials and ages. It also aims to evaluate the relationship between raw material and wood pellet parameters. In this process, the method used emphasized the measurements of the chemical-physical and quality parameters of the materials and pellets, respectively. These analyses were subsequently carried out through a comparative test with the quality standards of SNI (Indonesian National Standard) 8021-2014 and SNI 01-6235-2000. To analyze the relationship between raw material and wood pellet quality parameters, a statistical test of Pearson correlation (product-moment) was conducted. Based on the results, the pellets produced from post-mining land revegetation reached SNI quality limits on the parameters of water content, density, fixed carbon, and heat. This proved that all the chemical-physical features of the raw materials had a relationship in improving the quality of wood pellets. Regarding the comparison between types, the Acacia mangium pellets relatively had the best quality.
