The process of making supercapacitor cell electrodes is through a process of pre-carbonization, chemical activation, chemical carbonization in N2 gas and physical activation using CO2 gas. Analysis of the physical properties of the carbon electrodes showed that the sample had a density value of 0.65 g/cm3 or a reduction percentage of 36.90%. This research shows that areca leaf midrib biomass has the potential to be used as a carbon electrode for supercapacitor cell applications.enAmbon moss banana fibercarbon electrodephysical activationsupercapacitorArticle
