Low energy density, high moisture content, irregular biomass shape (leaf biomass), low carbon content, and high tar content are the main limiting factors. These limitations can be overcome by providing pre-treatment before using biomass as an energy source or fuel. The most common pretreatment is torrefaction. Torrefaction will produce solid, liquid and gas substances. Torrefaction experiments carried out to meet research objectives are based on a Central Composite Design experimental design which is a 2-factor design. The Central Composite Design allows for the estimation of coefficients in a second-degree polynomial regression and quadratic response surface modeling. In this study, there are two factors, namely torrefaction temperature expressed as variable X1, and residence time variable X2. The torrefaction temperature used is 200°C - 300°C, and the residence time is 10 minutes to 20 minutes. The RSM interaction with 13 random runs by Minitab 18 software. Torrefaction of kesambi leaf biomass with a combination of temperature and torrefaction time produces good torrefaction products. The results showed that the optimum conditions for torrefied products based on calorific value response were obtained at a temperature of 300°C and a torrefaction time of 20 minutes with a torrefied product prediction.
