Main goal of this current research is to produce activated carbon from waste cigarette filter sampoerna as supercapacitor electrodes. The process synthesis of the activated carbon utilized chemical activation by using Potassium Hydroxide (KOH) as activator in which the mass ratio of the sample and KOH was 1:2, 1:3, and 1:4. The samples were chemically activated then flowed by N2 gas at a t…
