Sintesis Elektroda Karbon Menggunakan Aktivator Koh Berbasis Limbah Sabut Kelapa Muda Sebagai Aplikasi Superkapasitor

---

Supercapacitor is a storage device consisting of carbon electrodes, separator and
electrolyte and current colector. In this research, carbon electrodes were made from
young coconut fiber biomass with variations in KOH mass ratio of 1:0.20; 1:0.25
and 1:0.30 have been successfully prepared. The carbonization temperature and
activation temperature are 550˚C and 750˚C respeetively. Carbon electrode
samples coded SKM-020, SKM-025 and SKM-030 were characterized using
density calculations, scanning electron microscopy (SEM) and X-ray diffraction
method to determine the physical properties of the carbon electrodes. The
electrochemical characterization used cyclic voltammetry (CV) and galvanostatic
charge-discharge (GCD) methods. The percentage values of each density for
SKM-020, SKM-025 and SKM-030 are 69.45%, 59.8% and 64.7% respectively.
Microstructure analysis using XRD proves that the carbon electrode is
semicristallice indicated by the presence of wider peaks at 2θ angles around 24˚
and 44˚ with the highest Lc value of 8.134 in the SKM-025 sample. C
haracterization of electrochemical properties using cyclic voltammetry method
obtained specific capacitance values of 180.63 F/g, 231.17 F/g and 203.73
F/g with samples SKM-020, SKM-025 and SKM-030 respectively and using
galvanostatic charge-discharge method obtained specific capacitance values of
211. 32 F/g, 284. 94 F/g and 223.61 F/g for samples SKM-020, SKM-025 and
SKM-030, respectively. From the analysis of physical and electrochemical
properties, the best result for supercapacitor performance from young coconut coir
biomass is SKM-025.
