The increase in global energy consumption is one of the impacts of the rapid growth of the industrial sector. This condition encourages the need for the development of sustainable alternative energy sources such as supercapacitors that can be made by utilizing biomass waste as raw material for renewable energy storage, one of which is pineapple stem waste. Pineapple stem was chosen because it has carbon content such as lignin and cellulose as much as 31.68%. This research was conducted to analyze the quality of carbon electrodes made from pineapple fruit stems activated with various types of chemicals, and evaluate the performance in symmetrical and asymmetrical electrode configurations in supercapacitor applications. The precarbonization process of pineapple fruit stems was carried out using an electric oven at 200°C for 2 hours. Chemical activation used KOH, ZnCl2, and NaOH activators with a concentration of 0.5M at 80°C for 2 hours. High temperature combustion was carried out up to 800°C in an N2 gas environment. Electrodes were fabricated symmetrically and asymmetrically in the fabrication of supercapacitor cells. The X-ray diffraction pattern showed that the activated carbon electrode had two broad peaks in the 002 and 100 planes which identified the presence of amorphous structure in the activated carbon. Morphological analysis of the carbon surface showed large holes like pores on the electrode surface. X-ray energy dispersive showed that the pineapple fruit stem activated carbon electrode consisted of several important elements such as C, O, Mg, K, Na, and Zn. Adsorption desorption isotherms showed different pore structures and specific surface areas on each electrode. The symmetric electrode produced a specific capacitance value of 219,75 F/g at the KOH electrode and the asymmetric electrode produced a specific capacitance value of 235,0 F/g at the KOH-NaOH electrode. The results of this study indicate that carbon electrodes activated using KOH are proven to provide the best performance as electrode material for supercapacitor applications.
