Abstract

One of abundant waste in timber industry is Aquilaria malaccensis (Gaharu) wood Sawdust. To control this problem Aquilaria malaccensis wood Sawdust can be used as biochar which will be useful for soil improvement. The purpose of this study was to determine the chemical properties of biochar derived from the Aquilaria malaccensis wood Sawdust. Making biochar is done by burning the seeds using a furnace with a temperature of 250°C and 350°C, then ground and sieved with a size of 355 micrometers carried out at the Limnology and Water Resources Research Center. Chemical property analysis using X-Ray Fluorescence Spectrometer (XRF) at the Lampung Advanced Characterization Laboratory-BRIN. Based on the results of the analysis using XRF showed that the highest content of biochar is Calcium (CaO) around 78-84%, Phosphorus (P₂O₅) around 4-5%, then Potassium (K₂O) around 2%. Based on chemical properties biochar from Aquilaria malaccensis have high potential as soil amendments.
