NOVELTY - The method involves making activated charcoal or activated carbon from ivory coconut shells by cleaning the husk attached to the coconut shell and cutting into small pieces and drying in the sun for seven days, in which carbon powder is obtained from the coconut shells, and the shell carbon is mixed with Sodium hydroxide and soak for 24 hours in chemical activation process, and making the reduced graphene oxide (rGO) from ivory coconut shells by cleaning the fiber attached to the coconut shells and cutting into small pieces and drying in the sun for seven days, and roasting, crushing and carbonating to obtain carbon powder, and filtered to obtain the sediment. USE - Manufacturing method of activated carbon/graphene oxide electrodes from ivory coconut shells. ADVANTAGE - Utilizes material from natural materials, increases the specific capacitance value on supercapacitor electrodes, and reduces environmental waste.
