Supercapacitors are environmentally sustainable energy storage devices that have attracted significantly attention due to their excellent performance. In this research, supercapacitor electrode materials were prepared from tilapia scales waste biomass with varying concentrations of KOH as a chemical activator, namely 0.1 M, 0.2 M, and 0.3 M with sample codes SI-01, SI-02 and SI-03, respectively. The preparation electrode process includes pre-carbonization, chemical activation using KOH, carbonization, and physical activation with CO2 gas. Characterization results show that the pore structure of the electrode can be controlled through variations in KOH concentration, resulting in a mesoporous dominant pore structure with high carbon purity. Sample SI-02 showed the best performance, characterized by the highest density shrinkage of 29.53%, semicrystalline structure with XRD peaks at angles of 20°-21° (002) and 42° (100), and the content of functional groups such as O-H, C-H, C-C, C≡H, and PO4³-. The N₂ adsorption-desorption test resulted in hysteresis loop IV with the highest specific surface area of 195.236 m²/g and pore volume of 0.404 cm³/g on SI-02. Testing the electrochemical properties using the cyclic voltammetry (CV) method with H₂SO₄ electrolyte showed that sample SI-02 has the highest specific capacitance value of 148.50 F/g. Based on the physical properties of carbon electrodes and the electrochemistry of supercapacitor cells, it shows that variations in KOH concentration in the activation process can improve the performance of supercapacitor electrodes made from tilapia scales waste, the abdibility to be used as an environmentally friendly electrode material for energy storage applications.
