ABSTRACT
The electrical energy crisis occurs due to the increasing scarcity of non renewable
electrical energy source. The focus of research is currently developing on how to
store electrical energy using biomass energy. This study aims to analyze the
specific capacitance of different electrolyte solution for supercapacitor application
with electrode made from palm frond. Pre-carbonization of palm frond was
carried out using an electric oven with a temperature of 100-250 oC for 2 hours.
Physical activation using KOH activating agent with a concentration of 0.5M at
80 oC for 2 hours. Carbonization were carried out at a temperature of 600 oC using
N2 gas environment and followed by a chemical activation process using CO2 gas
at a temperature of 850 oC for 2.55 hours. Variety of electrolyte solution of 6M
KOH, 1M H2SO4 and 0.5M Na2SO4 were used in the manufacture of
supercapacitor. The density of carbon electrodes decreased significantly after
carbonization-physical activation by 20.75%. Infrared fourier transform show that
activated carbon has functional groups O-H, C-H, C≡C, and C = C at wave
numbers 3255.98-3147 cm-1, 2697.56-2467.06 cm-1, 2934.82-2884.67 cm-1,
896.94-748.41 cm-1, 2331.07 cm-1, 2356.15-2311.79 cm-1, and 1590.38 cm-1. Xray
diffraction pattern of carbon electrodes show the presence of two wide peaks
at scattering angle of 23.56o and 45.46o in accordance with plane 002 and 100
which identify activated carbon as having a semicrystalline structure. The
variation of the electrolyte solution with carbon electrodes made from palm fronds
produced specific capacitance values of 122.20 F/g for 1M H2SO4, 114.68 F/g for
6M KOH and 79.26 F/g for 0.5 M Na2SO4.
Keywords : Palm Frond, Activated Carbon, Electrolyte Solution, Supercapacitor.
