Abstract: The waste of husks and corn cobs that relatively abundant in Indonesia is mainly used as animal feed. Its utilization is still not maximized and pollutes the environment a lot. Corn husks and cobs contain silica, which can be used as a raw material in the manufacture of SiO2 silica gel. This study aims to obtain SiO2 from corn husk and cob ash using the sol- gel extraction method to determine the effect of ashing temperature and mass ratio of corn husks and cobs and the characteristics of silica gel. The method used in this study is the sol-gel method. The characterization of silica gel utilizes FTIR (Fourier Transform Infra-Red) and XRF (X-ray fluorescence) as a process. The result indicates that the FTIR shows an absorption pattern of silica with silanol (Si-OH) and siloxane (Si-O-Si) groups, with an amorphous silica phase at an ashing temperature of 750 ℃ and crystalline silica at an ashing temperature of 850 ℃. XRF results determine that the yield of Si and SiO2 produced in corn husks tends to be higher than corn cobs and at an ashing temperature of 750 ℃ tends to be higher than 850 ℃.
