Supercapacitors are renewable energy storage devices that have relatively high power density and performance, as well as fast charging-discharging. Activated carbon is one of the materials that can be used as electrodes because from amorphous carbon materials with high porosity and large surface area. The addition of catalysts aims to convert amorphous carbon into graphitic carbon with a hight degree of graphitization. This research utilized oil plam frond waste (PKS) without and with the addition of 0,1 M and 0,2 M NiCl2 catalysts with the respective sample codes namely PKS, PKS-01, and PKS-02. Making carbon electrodes is carried out using several processes, precarbonization process, chemical activation using a KOH activator and the addition of a NiCl2 catalyst, the carbonization process using N2 gas at a temperature of 600oC and physical activation using CO2 gas at a temperature of 800oC. The carbon electrode from PKS has a amorphous structure which is characterizes by the presence of (002) and (100) peaks at angles 22o-23o and 43o-45o which contain the C-H, C=O, and O-H functional groups. The nanofiber structure with the highest amount is owned by the PKS-01 sample with a precentage of carbon, oxygen and nickel elements of 91,09%, 6,96%, and 0,98% respectively. The isothermal adsorption-desorption of N2 from the PKS carbon electrode without and with the addition of the NiCl2 catalyst shows combined type I and IV behavior with the H4 hysteresis loop showing a total speciric surface area and total pore volume of 688,796 m2/g and 0,030 cm3/g, with a pore distribution of 3,5145 nm. Electrochemical analysis of supercapacitor cell using the Cyclic Voltametry and Galvanostatic Charge-Discharge methods with 1 M H2SO4 electrolyte produced the highest specific capacitance values in the PKS-01 sample of 359 F/g and 254 F/g respectively. Based on the physical and electrochemical properties of supercapacitor cells derived from oil plam frond waste, the addition of NiCl2 0,1 M catalyst to the carbon matrix can improve the performance of supercapacitors cell electrodes.
