The impact of emerging agriculture as the dominant sector in Indonesia was abundant in agricultural waste such as rice husk and rice straw. Slow pyrolysis was proposed as processing treatment of residue to get bio-char and bio-oil at 250 °C using a simple stainless-steel reactor. The selected temperature for the pyrolysis process based on TGA result and the optimum condition of the combustion process. Bio-char produced was 57 wt% which porosity range around 50 µm identified from SEM image, which could be used as bio-sorbent materials. While bio-oil has phenol as a dominant compound known with its bactericidal activity. Based on IR spectrum, the pyrolysis process only reduces the small amount of water and organic compound of biomasses. Even though from physical appearance after the pyrolysis process both biomasses become different, but from SEM image, pyrolysis process did not change materials structure excessively. The impact of the pyrolysis process on rice husk difference with rice straw because of its chemical compound and also size of materials.
