South Sumatera Province has vast forests with a diversity of crops potential for biomass fuel. A biomass-based energy source is one of the options to meet the energy needs for human life. This study aims to assess the potential of biomass from wood, leaves, and grass as a source of renewable energy, such as firewood and charcoal. The basic properties of biomass fuels, including calorific value, sulfur content, the flame temperature, and flue gas emissions are presented in this article.
