Abstract:
Carbonization temperature affects the manufacture of carbon electrodes using oil palm leaf
biomass. The process of making carbon electrodes starts from the pre-carbonization process
using a temperature of 200oC, grinding using ball-milling, sieving carbon powder with a size
of 53 μm, then the sieved powder is activated using a KOH activator with a concentration of
1M, then the powder is molded into pellets using a hydraulic press. The sieved powder sample
was subjected to thermogravimetry analysis (TGA) where the temperature increased, the mass
decreased. The carbonization process is carried out with temperature variations of 600oC,
700oC, and 800oC with N2 gas flowing. The higher carbonization temperature affects the
density value so that the density values obtained in the DKS-600, DKS-700, and DKS-800
samples are respectively 0.9632 gr/cm3, 1.0409 gr/cm3, and 1.1954. gr/cm3.
