Bamboo is one type of grass which is part of non-timber forest products. The chemical properties of bamboo contain of cellulose, lignin, pentosan, ash, and silica. This study using waste of betung bamboo base.  To make tar from betung bamboo it is necessary to go through a pyrolysis process. Pyrolysis is a process of thermal decomposition carried out in an inert condition. In this study using the fast pyrolysis method where the main product is tar while charcoal and non-condensable gas are by product. Tar start producing at low temperature and ended at temperature above 600°C because of secondary reaction mechanism that cause tar start to decompose to gas and charcoal. This study using 500°C to 900°C with, 1 hour and 3 hours temperature process condition. The optimum mass result of tar reached at 1 hour 600°C is 19.2420 gram while at 3 hours 600°C is 13.1972 gram. Based on this research, it can be concluded that lower temperature process produced more tar and higher temperature process decrease mass of tar produced, in this case the optimum temperature for betung bamboo pyrolysis reached at 600°C.
