Research on silicon oxide (SiO 2 ) from biomass was studied. This study used the biomass of rice straw which is one of the rice agricultural wastes. Rice straw was treated with acid using hydrochloric acid (HCl) before burning. Rice straw charcoal was burned in the furnace at a temperature of 400 °C to 900 °C with a heating rate of 1.7 °C/min for 2 h. The increase in heating temperature was varied at 800 °C, 850 °C, and 900 °C. Silicon dioxide samples were characterized and analyzed based on its electrical properties and functional groups using LCR-meter and FTIR. The extraction of silicon dioxide from rice straw was successfully carried out using a modified method in previous studies. Based on functional group analysis and electrical impedance properties of silicon dioxide rice straw samples, the best result was obtained at 800 °C ignition temperature treatment.
