Research has been conducted to test silica function groups based on rice husks with temperature variations and concentrations of Cetyltrimethylammonium Bromide as raw materials for mesoporous silica. In this study, rice husk silica was synthesized by alkaline method with variations in CTAB concentrations of 2.0%, 2.5%, 3.0%, 3.5%, and hydrothermal treatments with temperature variations of 120, 130, 145, and 160ºC for 1 hour in an autoclave. Fourier-Transform Infrared (FTIR) results showed the presence of the most dominant clusters, namely Si-O-Si and other groups such as C-H, -H, O-H, and –OH. Therefore, silica-based rice husks can be used as raw materials mesoporous silica
