Sintesis Dan Karakterisasi Karbon Aktif Berbasis Serabut Kelapa Muda Sebagai Elektroda Superkapasitor

---

ABSTRACT
Supercapacitor is energy storage devices consisting of electrodes, electrolyte, current collectors, and separator. In this research, carbon electrodes are made from young coconut fiber biomass (SKM) waste using ZnCl2 0.5 M as activation agent and variations in physical activation temperatures. Carbon electrodes preparation begins with a pre-carbonized process of 200oC temperatures for 1 hour and 30 minutes, continued with chemical activation using ZnCl2 0,5 M as activation agent, then the carbonization process uses N2 gas as well as physics activation using CO2 in temperature variation of 700oC, 750oC, and 800oC. Analysis of the nature of electrodes cell capacitorbased fiber young coconut fibers sample shows that the activation physics 750oC sample is best, agreeble with the density of carbon electrodes declined by 42,28% after the carbonization-activation process. Carbon electrodes represent semicrystalline based on the characterization of the X-ray diffraction, marked with a ramp peak at 2θ at about 22o and 44o. The SKM-750 has a highest of Lc/La ratio an average number of microcrystalline inner layers (Np), are 0.85 and 4.39. Using Scanning Electron Microscope shows that SKM-750 has a pore with diameter 4.2 nm and the percentage of carbon content is 92.4%. SKM-750 has the highest of specific capacitance value, namely 215 F/g.
Keywords: Coconut, Electrode, Carbon, Activation.
