Karbon aktif berbasis kulit ari kedelai (testa sojae) dengan variasi penambahan graphene untuk elektroda sel superkapasitor

The global energy crisis caused by increasing energy consumption and the limitations of fossil resources drives the development of environmentally friendly energy storage technologies, such as supercapacitors. Supercapacitors require electrode materials with high conductivity, large surface area, and good electrochemical stability. This study aims to develop activated carbon electrodes derived from soybean seed coat waste (Testa Sojae) with the addition of graphene for supercapacitor applications. The electrode synthesis involved pre-carbonization at 200°C, chemical activation using 0.1 M KOH with and without graphene (0.01 g and 0.03 g), carbonization at 600°C, and physical activation using CO₂ at 800°C. The results revealed that the addition of graphene significantly influenced pore morphology, elemental composition, and electrochemical performance. The electrode with 0.01 g graphene (KAD-01) exhibited a more defined amorphous structure, more open and uniform pores, and a carbon content of 74.0%. The pore structure was classified as mesoporous, which plays an important role as an ion diffusion channel, thereby facilitating electrolyte access to the active sites. Electrochemical tests showed a maximum specific capacitance of 369 F/g, specific power of 184.23 W/kg, and specific energy of 51.175 Wh/kg. This study contributes to the development of eco-friendly carbon materials derived from local biomass waste and demonstrates the potential of graphene in enhancing the performance of supercapacitor electrodes. These findings are expected to provide a foundation for future research in the development of sustainable energy storage technologies.
