Rice husk as a by-product of the rice milling process is a material that can still be processed to be a product that can be used in various applications. The potential for the commercialization ofrice husks is still hampered by its low economic value. By using the heating method using an inert gas,rice husk can be converted into a composite whichcontains mostly silica and carbon, a wellknown component with excellent adsorbent properties. In this research,the utilization of ricehusk into silica/carbon composites was done by using three different methods. Common heating under temperature of 800oC (S), heating process under temperature of 800oC using furnace equipped with inert gas (CS), and heating process under temperature of 800oC using furnace equipped with inert gas with addition of glucose solution (CSL) were carried out in order to obtain three different kinds of composite. Analysis and characterization using Fourier Transform Infra-Red and X-Ray diffraction were performed to observe the properties of the composites. As the result, CSL has the highest adsorption capacity and Langmuir’s model adsorptive behavior.
