The research pyrolysis of acacia wood waste has been carried out. This research was conducted to determine the optimal conditions that can be used for the pyrolysis process of acacia sawdust and the effect of the pyrolysis products. The pyrolysis process was carried out on the principle of slow pyrolysis using a batch type reactor. Pyrolysis was carried out by varying the final temperature of pyrolysis 375°C, 475°C, and 575°C and variations of heating rates 5°C/min, 10°C/min, and 15°C/min with a holding time of 20 minutes. The content of cellulose, hemicellulose and lignin at raw material was determined with the van soest method and the values are 32.75%, 35.16%, and 16.81%, respectively. The result of the pyrolysis process in the form of char at the final temperature of 575°C with a heating rate of 5°C/min produces a calorific value of 6.816 cal/gram. In the tar (oil) tested using GCMS, the acacia tar contains quite high phenol, acetic acid, 2 propanone. The results of pyrolysis can be seen that the highest activation energy value is found in the pyrolysis process with a variation of the heating rate of 15°C/min and the final temperature of the pyrolysis 575°C which is 49.56 kJ/mol.
