|a Cogon grass is one type of agricultural wastes that can easily be found around the world. A cogon grass contains with relatively low lignin (5.67%), ash (8.24%) and acceptable holo-cellulose and cellulose solubility of 64.9% and 37.1% respectively. The focus of this paper is to analyse the effect of acid treatment of silica extraction of cogon grass due to silica as a raw material that can be apply in industrial. Parameters such as concentration of acid and weight percentage used in cogon grass during organic and inorganic leaching method were also compared. In this paper, citric acid (C6H8O7) and hydrochloric acid was used for production of silica from cogon grass. Samples were characterized using Scanning Electron microscopy (SEM), X-ray diffraction (XRD) and Thermal gravimetric Analysis (TGA). The result indicates that highest percentage silica of cogon grass after leaching was on 1.0M via HCL acid leaching and has an amorphous structure.
