This study is aimed at utilizing empty fruit bunches of oil palm (Elaeis guineensis Jacq.) and oil palm shells to be one of the renewable energy resources in the form of charcoal briquettes, investigate the effects of variation of press load and material composition, and examine the optimum press load and concentration ratio of materials in the charcoal briquettes made from oil palm empty fruit bunch (EFB) and oil palm shell (OPS). EFB and OPS were carbonized using an electric retort at the temperature of 400o C for 3 hours. This study employed the research design of completely randomized managed in 2 treatment factors, i.e. the press load of 2000 psi, 2500 psi, and 3000 psi and the ratio of material composition (EFB and OPS) of 75%:25%, 50%:50%, and 25%:75% in which each treatment was repeated five times. Subsequently, the quality examination of charcoal briquettes was conducted using physical parameters (water content, specific gravity, and calorific value) and chemical properties (ash content, volatile matter content, and fixed carbon). The results showed that the quality of charcoal briquettes made from EFB and OPS were as follows: the moisture content of 6.212 - 9.386%
