The synthesis of RGO material from corn cobs went through several stage: carbonization, oxidation and reduction. The synthesis of RGO used a modified Hummer method, and was reduced using the reducing agent ascorbic acid. The synthesized RGO was then characterized using Fourier Transform Independent Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Energy Dispersive Spectroscopy (EDS). Electrochemical analysis using the cyclic voltammetry method, the specific capacitance value obtained showed that RGO had a higher capacitance value than GO. The research results showed that carbon from corn cobs, which has not been utilized optimally, can be synthesized as a basic material for making RGO as a quite promising material. ## Keywords - Corncob - Graphene - Characterization (materials science) - Electrochemistry - Oxide - Carbon fibers - Electrode - Materials science - Chemical engineering - Nanotechnology - Chemistry - Metallurgy - Composite material - Physical chemistry - Composite number - Organic chemistry - Engineering - Raw material --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
