Abstract
Coconut shell biomass has the potential to be used as a raw material for making
porous activated carbon. This study aims to process coconut shell biomass as a basic
material in the manufacure of porous activated karbon. Initial preparation begins with
cleaning the sample, drying the sample in the sun, cutting the sample into smaller
sizes, followed by the pre-carbonization process using a kiln with various burning
times of 40 minutes, 50 minutes, 60 minutes and 70 minutes and neutralization of the
sample pH. Variations in burning time affect the resulting charcoal. The initial mass
of the charcoal after pre-carbonization combustion is always greater than the mass of
the charcoal after neutralization due to raw materials that have not been completely
burned and ash. The short time makes the raw material not completely burnt and the
further increase in burning time causes an increase in the ash content of the charcoal
due to the burning of organic matter in the charcoal. Charcoal at 50 minutes showed
the highest yield of charcoal to be used as the basic material for porous activated
carbon.
