Palm oil waste is an abundant biomass resource in Indonesia that is not well utilized as a raw material for producing high value-added materials. One product that is possible to be manufactured from oil palm biomass is activated carbon. Characteristics of high porosity and good conductivity will lead the activated carbon suitable as an electrode of supercapacitor material. This research focused on the increasing yield of activated carbon from palm oil waste by hydrothermal carbonization for supercapacitor applications. Preparation of activated carbon is carried out means of two main steps namely carbonization and activation. In this research, carbonization is done by hydrothermal process while activation is done by physical activation. The activation of mesopore area of the carbon has been taken place by using ZnCl2 and CaCl2 as a chemical activating agent during the hydrothermal process. In this research will investigated the effect of carbonization temperature and mass ratio of activating agent during hydrothermal carbonization. The activated carbon produced from empty fruit bunches has a surface area of 12 - 1571 m2 / g and a pore size of 2.0 – 6.8 nm. In this study activated carbon is used as a working electrode in symmetric hybrid supercapacitor. This palm-oil based supercapacitor cell has a capacitance of 4.305 F/g.
