Pemanfaatan Limbah Merang Padi (Oryza Sativa L.) Sebagai Elektroda Karbon Superkapasitor Dengan Variasi Konsentrasi Aktivator Koh

---

The phenomenon of supercapacitors as an energy storage technology is increasingly becoming a concern discussed by various group of researchers. The development of supercapacitors based on agricultural waste is one of the innovations for making activated carbon electrodes. The main components of supercapasitor include electrodes, current collectors, electrodes, and separators are the main important components of supercapacitor cells. In this study, carbon electrodes were made from the rice panicle agricultural waste with variation of KOH molarity in chemical activation of 0 M, 0,25 M, 0,5 M, and 0,75 M with sample codes MP-0, MP-0,25, MP-0,5, MP-0,75 respetively. The rice panicle carbon electrode was made through several stages including pre-carbonisation, chemical activation, and continued with physical activation. X-ray diffraction pattern analysis of MP supercapacitor cells showed a semicrystalline structure in the (002) and (100) reflection planes characterized by two broad peaks at 2θ angles around 20° and 44°, representing the
(002) and (100) reflection planes, respectively. BET analysis produced isotherm curves indicating the rice straw supercapacitor cell electrode includes micropores and messopores with the highest surface area was produced by the MP-0,25 electrode of 438,970 m2/g with a total pore volume of 0.286489 cm3/g. Characterization of electrochemical using cyclic voltammetry and galvanostatic charge-discharge methods resulted in the highest specific capacitance in the MP- 0,25 sample, of 467.2 F/g and 279.2 F/g respetively.
