Abstract
Supercapacitor is considered as a promising technology in the energy storage system (ESS) because of high power, large currents, and excellent cycle stability. In this study, activated carbon was used as the constituent material for electrodes because of its porous structure, a large surface area, high conductivity, low cost, and renewable. Activated carbon was synthesized from salacca peel by hydrothermal carbonization and chemical activation with KOH. In this research, the effect of operating pressure and temperature in the hydrothermal carbonization process was studied. The operating pressure was varied so that the water phase changed from vapor phase to liquid phase (subcritical water). The temperature was varied at 225
