Abstract

Previously, Sengon wood waste from existing sawmills was underutilized. Therefore, one way to utilize this wood waste is to convert it into fuel because the energy demand in this world continues to increase. In doing so, an initial study was conducted to determine the characteristics of wood pellets from Sengon wood using Scanning Electron Microscopy-Energy Dispersive of X-ray Spectroscopy (SEM-EDX), resulting in more porosity in the middle than at the bottom and top because the middle is denser than the inside of the Sengon wood pellet, while the upper part has fewer pores because the outer part of the wood pellet experiences friction with the ring die so that the resulting pores are smoother. Meanwhile, on average, the elements that have been tested have the highest atomic weights, namely C-K elements (40.36%); elements O-K (52.08%); element CuL (1.29%); Elements of AIK (0.85%); SiK element (1.95%); CIK elements (0.42%); KK elements (1.39%) and CaK elements (1.64%).
