The research problem would be solved in this research is the dependence TiO2-activated carbon composite of the cashew nut shell against the capacitance supercapacitor on the calcination temperature. To solve the problems, we determine the influence of calcination temperature on the capacitance supercapacitor to the composite TiO2-activated charcoal cashew nut shell. The composite TiO2 - activated charcoal cashew nut shell passed through a heating process for 5 hours with calcination varies temperature. The activated composite then used as a supercapacitor electrode material. Some characteristic of the electrode are reported.
