Abstract:
Supercapacitor electrode material of Rubber Wood Saw Dust (RWSD) was fabricated by
using an experimental method with variation RWSD and KOH mass ratio of 1:1, 1:3, 1:5 and
1:7. The RWSD was carbonized using N2 gas at a temperature of 600 °C for ± 8 hours to
produce pellets with high carbon content. Carbon activation process was done by a
combination of physical and chemical activation. Physical activation using CO2 gas was
performed at temperature of 900 °C for 2 hours while the chemical activation was low
temperature of 80 °C for 2 hours in a solution of KOH. Results of density measurements
indicated that the value of the carbon electrode density increased with increasing mass of
KOH. The measurement of specific capacitance showed that the specific capacitance of the
electrode increased with increasing mass ratio of KOH and reached the higest value at the
mass ratio of 1:5, this is due to the activation of KOH caused the particle size become smaller
and porous, The best sampel in fil reserch was 1:5 sampel being pesifik capacitance an high
of 72,82 F/g
