The objective of this study was to determine the properties of biochar from meranti ( Shorea sp.) and oil palm ( Elaeis guineensis ) empty fruit bunches (OPEFB). Biochar was produced using a traditional kiln with a temperature of 400°C and 600°C. The char yield, pH, and proximate analysis were evaluated. The results showed that the maximum char yield was obtained at 400°C, and the increase in temperature resulted in decreased char yield. At the same pyrolysis temperature, char yield was higher in meranti than OPEFB. The results revealed that the pH of meranti and OPEFB changed into basic after pyrolysis, which is essential when biochar is added to soil to neutralize soil acidity and increase the soil cation exchange capacity. The results also showed an increase of fixed carbon in meranti and OPEFB after pyrolysis at 400°C and 600°C. The higher heating values (HHV) in meranti and OPEFB increased after pyrolysis, with a remarkable increase of HHV observed in meranti than OPEFB, showing a higher potential of biochar from meranti to be used for bioenergy application than OPEFB.
