Potensi Ampas Dan Air Perasan Buah Belimbing Wuluh (Averroha Bilimbi L.) Sebagai Karbon Aktif Dan Elektrolit Untuk Aplikasi Super Kapasitor

---

The global energy crisis and environmental degradation caused by fossil fuel utilization have driven innovation in more environmentally friendly energy storage technologies, one of which is the supercapacitor. This study explores the potential of bilimbi fruit (Averrhoa bilimbi L.) as a source of activated carbon as well as a natural electrolyte material in symmetric supercapacitors. Bilimbi fruit residue was processed into activated carbon through chemical activation using agents such as H₃PO₄, KOH, and ZnCl₂. The physical properties of the electrodes were characterized using X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray. Electrochemical characterization was conducted through cyclic voltammetry and galvanostatic charge-discharge methods. The results showed that activated carbon treated with H3PO4 exhibited a semi crystalline structure, porous morphology, and dominant elements including carbon, oxygen, and magnesium. Electrochemical tests revealed that the supercapacitor using bilimbi fruit extract as the electrolyte achieved the highest specific capacitance of 191,82F/g and 234.47F/g based on cyclic voltammetry and galvanostatic charge-discharge respectively. However, the performance of the natural electrolyte derived from bilimbi fruit still falls short compared to sulfuric acid (H2SO4) electrolytes in terms of conductivity and capacitance. Nevertheless, these findings indicate that bilimbi fruit holds promise as an alternative source of carbon and natural electrolyte for the development of sustainable and eco friendly supercapacitors.

Keywords: Activated carbon, averrhoa bilimbi L., supercapacitor, natural electrolyte, chemical activation, specific capacitance.
