Abstract. The production of supercapacitor carbon electrodes based on sugar palm frond waste using chemical and physical activation combinations have been successfully carried out. The chemical activation was carried out using 0.3 M KOH activating agent and the physical activation using CO2 gas at a temperature of 900oC for 2.5 h.

After the carbonization-physical activation process, the mass, thickness, diameter, and density of the electrodes decreased in the percentage of 60.87, 30.43, 24.08, and 5.71%, respectively. The PA-0.3 electrode has a semi crystalline structure, which characterized by the presence of two broadening peaks at a scattering angle around of 25o and 46o. The specific capacitance of the PA-0.3 electrode based on the scan rate variations is 90 F g-1 for 1 mV s-1, 82 F g-1 for 2 mV s-1, and 71 F g-1 for 5 mV s-1.
