Carbon electrodes in this study were produced from oil palm empty fruit bunches. The carbon electrodes production utilized chemical activation using Kalium Hydroxyde (KOH) which various concentrations of 0.3 M, 0.6 M and 0.9 M. The samples were chemically activated and mold to form pellets of 0.75 g mass, then were flowed by N2 gas at a temperature of 600°C and followed by physical activation …
