Abstract:Rice straw waste in Indonesia is abundant and not yet used optimally. The composition of rice straw is 40% cellulose, 30% hemicellulose, 15% silica and 15% lignin so it is potentially to be a raw material of active carbon and supercapasitor electrode. Many efforts has been done to increase the value of capacitance of electrode like increase the surface area with activation and milling process. In this research used the variation of activator substance and the variation of milling velocity, they are H3PO4 450 r… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
