Biomass-based porous carbon electrodes have been widely used as a basic material for making supercapacitor cell electrodes, because its application can be applied in the long term, sustainable, renewable, easy to find and has economic value. This research used biomass melinjo fruit shell (CBM) with variations in the addition of melamine mass, namely 0, 0.1, 0.3, and 0.5 g as carbon electrodes f…
