Pembuatan Elektroda Karbon Dari Biomassa Kulit Petai (Parkia Speciosa) Dengan…

ABSTRACT Synthesis of carbon electrode based on petai peel biomass has been succesfully made using a variation of concentration of KOH activator. The synthesis was started by drying the samples under the sun ray, and then drying them using an oven at temperature of 110° C then the samples entered the pre-carbonization process on 250° C. The samples were mashed then with ball milling and …
