To utilize various potential agricultural residues, pellet making was performed and the pellets obtained were characterized in this study. Oil palm empty fruit bunch (OPEFB), oil palm frond (OPF), oil palm shell (OPS) and oil palm mesocarp (OPM) were employed as feedstock. Biopellet production was started with material crushing to get uniform material and then continued with pellet forming. Pellet making was conducted using conventional pelletizer under temperatures of 150, 200 and 250°C for 15minutes. Some characteristics were measured to determine biopellet quality, i.e. moisture content, density, ash content and calorific value. Based on the water content, ash content, density and calorific value, OPM biopellets that pressed at 200 and 250°C showed the best formula. The characteristics of this biopellet were moisture content of 1.7-1.9%, ash of 6.85-7.45%, and calorific value of 3,814-4,724kcal/kg.
