Rice husks as abundant agricultural waste contain quite high silica, between 87% to 97% of dry weight after burning. This research aims to utilize rice husks as a sustainable alternative source of silica, as well as explore their potential applications in the ceramics, concrete, and other construction materials industries.To extract silica content, there are types of methods that can be used, including alkaline fusion, sol-gel methods. The synthesis method used is the sol-gel method, which is a bottom-up approach to produce nanosilica by converting the precursor solution into a gel and then drying it. The characterization process is carried out using techniques such as XRF, XRD, and SEM to ensure the quality and structure of the resulting nanosilica. The results of this research are expected to contribute to the utilization of rice husk waste in the field of construction and the development of environmentally friendly and valuable silica raw materials, as well as open up new opportunities in research and application of nanomaterials in various industries
