Indonesia is one of the active exporters of logs and sawn wood, so the waste generated is very large. One of the applicable technologies developed for the utilization of wood saw waste is to process it into liquid smoke through the pyrolysis process. The application of liquid smoke to plants can affect plant’s growth and production processes due to the presence of acetic acid and methanol. The purpose of this research was to find out about the properties of Surian sawn waste liquid smoke and how it could be used as a biofertilizer an Arabica coffee seeds. …The effectiveness of liquid smoke from sawn wood waste for the increase in height, stem diameter, and the highest number of leaves of coffee seeds was obtained at a concentration of 2.5%.
