Elektroda Karbon Aktif Dari Biomassa Pelepah Daun Pinang Dengan Variasi Konsentrasi Koh Untuk Aplikasi Sel Superkapasitor

---

Supercapacitors are renewable energy storage devices consisting of electrodes,
electrolytes, current collectors, and separators. In this study, carbon electrodes
were made from areca leaf midrib biomass waste with variations by activation
using KOH by various concentrations of 0.1 M, 0.2 M and 0.3 M, with the
sample codes being PDP-01, PDP-02, PDP-03. The fabrication of carbon
electrodes begins with pre-carbonization process sample at a temperature of
2000C for 2 hours, grinding by ball milling, and sieving to obtain particle size of
< 53 μm. The following process was an activation by chemical activation using
KOH. Then pellet was printed with a pressure of 7 tons using a Hyraulic Press,
carbonization process using N2 gas at a temperature or 6000C and physical
activation using CO2 gas at temperature or 7000C. Characterization of the physical
properties of carbon electrodes was done using X-ray diffraction, infrared Fourier
transform, scanning electron microscopy, and X-ray energy dispersive. The
characterization of the electrochemical properties of supercapacitor cells was
carried out by cyclic voltammetry. The functional group analysis of activated
carbon in this study showed that the functional groups formed are O-H, C-H,
C≡C, C=O, and C=C Microstructure analysis showed that the carbon electrodes of
Pinang Leaf midrib are amorphous phase indicated by the presence of sloping
peaks at an angle of 2θ around 240 and 440. The lowest microcrystalline dimension
of La and the highest Lc value belonging to the PDP-02 sample of 1.643 nm
28.318 nm, respectively. SEM characterization showed the of mesopores and a
few of micropores presented by PDP-02. Characterization using Energy
Dispersive X-Ray show that th sample has the element Carbon (C) with the
highest atomic percentage of 89.57% which is owned by the PDP-02. The
cyclical voltammetry results of each sample PDP-01, PDP-02, PDP-03 are 66.90
F/g, 130.08 F/g, 110.34 F/g so that the optimum specific capacitance is produced
by sampel PDP-02. Based on the results of the characterization of physical and
electrochemical properties, it can be concluded that the PDP-02 sample showed
the best performance compared to tat for the PDP-01 and PDP-03 samples.
