dc.description.abstractSupercapacitors are renewable energy storage devices consisting of electrodes, electrolytes, current collectors and separators. Electrodes are the main contributors in supercapacitors because they are made of nano-scale materials that have high surface area and porosity. This study utilized tiger prawn skin waste without and with the addition of 0,3M, 0,4M, and 0,5M KOH with respective sample codes, namely KU, KU-03, KU-04, and KU-05. The manufacture of carbon electrodes was carried out by several processes, namely pre-carbonization process, chemical activation with KOH activator, carbonization process using N2 gas at 600ºC and physical activation using CO2 gas at 800ºC. The highest density shrinkage value is owned by the KU-04 sample, which is 37,60%. The carbon electrode from tiger prawn skin has a semicrystalline structure characterized by the presence of peaks (002) and (100) at angles of 24°-25° and 45° which contains functional groups OH, C-H, C≡C, C-N, C=O, P=O, C-O, and N-H. The nanofiber structure with the highest number is owned by the KU-04 sample with the percentage of elements of carbon, nitrogen, oxygen, and phosphorus each of 54.39%, 11,41%, 23,11%, and 2,54%. The isothermal adsorption-desorption of N2 from tiger prawn skin-based carbon electrodes with KOH activation exhibits combined behavior of type I and IV with the H4 hysteresis loop which shows the largest total specific surface area and total pore volume in KU-04 of 526.175 m²g-1 and 0.371887 cm3g-1, with a pore distribution of 2.8271 nm. Electrochemical analysis of supercapacitor cells using the Cylic Voltammetry and Galvanostatic Charge-Discharge methods with 1 M H2SO4 electrolyte produced the highest specific capacitance values in the KU-04 sample of 315 Fg-1 and 244 Fg-1, respectively. Based on the physical and electrochemical properties of supercapacitor cells derived from waste tiger prawn skin, increasing the amount of KOH to the carbon matrix can improve the performance of supercapacitor cell electrodes.en_US
