Biomass is one of the renewable sources of energy with prospective needs to be considered at a national or even global scale. Chemical components and physical properties of materials can be used as bioenergy in the form of pellets. Pellets made by compressing biomass using pressure-heat, resulting in higher calorific values than origin material. Reclamation forests can be seen as a potential source of energy. Considering the generally less-optimal environment, further research regarding the characteristic of species grown in such conditions required. Firstly, research aimed to determine pellets characteristics of five species grown at the post-coal-mining area at Tabalong Regency, i.e. laban (Vitex pinnata) , sengon ( Paraserianthes falcataria ), sungkai ( Peronema canescens ), trembesi ( Samanea saman ) and johar ( Senna siamea ). Secondly was to evaluate the potential of species as energy sources. Measurement focused on forest debris, followed procedures set on SNI 8021-2014. Characteristics measured were moisture-content, density, lignocellulose, extractive, calor, ash, igniting-time, and burning-rate. Statistical analysis indicates that characteristics of origin material positive correlated with a caloric value of pellets except for moisture and ash. Pellets made of laban had the highest calorific value. Five species grown on the post-mining area had calorific values of pellets fulfilling the standard, which means those all are potential to be developed as an energy source.
