Supercapacitors are potential energy storage devices that are inexpensive to maintain and environmentally friendly. Electrode materials with varying carbonization temperatures were prepared using tiger prawn shell biomass (KUW). The manufacture of carbon electrodes is carried out using several processes, namely the precarbonization process, activation with a KOH activator, carbonization process, and physical activation using CO2 gas. As a precursor through the activation process of KOH and CO2. The pore structure can be adjusted by varying the CO2 activation temperature at 600℃, 700℃, and 700℃ with the respective sample codes, namely KUW-600, KUW-700 and KUW-800. The resulting electrode has a unique and efficient structure and pore regulation and has great potential for supercapacitor applications. The highest density loss value possessed by the KUW-700 sample was 19.16%. The carbon electrode from tiger prawn shells has a semicrystalline structure characterized by the presence of (002) and (100) peaks at angles of 23° and 43° which contain the functional groups O-H, C-H, C≡C, C-O, C=C, and P =O . Nanofiber and honeycomb structure with carbon purity of 43.55%. %. Isothermal adsorption-desorption of N2 from KUW-based carbon electrodes with variations in carbonization temperature shows a combined type I and IV behavior with the H4 hysteresis loop showing the largest total specific surface area and total pore volume on KU-700 of 526.175 m2g-1 and 0.107 cm3g-1 with a pore distribution of 3.6284 nm. Electrochemical analysis of supercapacitor cells using the Cyclic Voltammetry and Galvanostatic Charge-Discharge methods with 1 M H2SO4 electrolyte produced the highest capacitance values in the KUW-700 sample of 352 Fg-1 and 230 Fg-1 respectively. Based on the physical and electrochemical properties of supercapacitor cells derived from tiger prawn shell waste, varying the carbonization temperature in the carbon matrix can improve the performance of the supercapacitor cell electrodes.
