    Physical activation can affect the quality of carbon electrodes so that it can improve the performance of supercapacitor cells. In this study, carbon electrodes were prepared from the Khalas Dates Seeds by varying their physical activation temperatures of 7000C, 7500C and 8000C. Those samples were coded according to their activation temperatures, i.e. BKK-700, BKK-750 and BKK-800. The carbon electrode preparation began with the pre-carbonization process, followed by a chemical activation process using 0.3 M of KOH activator, then carbonized at a temperature of 6000C and continued to physical activation under CO2 flow. The BKK-750 sample has the highest density loss with an average density loss of 36%. The temperature of 750C was found to be the best for manufacturing activated carbon electrodes produced from the biomass of the Khalas Date Palm in improving the performance of supercapacitor cells in this study.
