TRANSFORMING FRUITS PEELS WASTE MANGOSTEEN (Garcinia mangostana L.) INTO BIO-BATTERIES

Abstract

This study introduces a novel bio-battery system derived from mangosteen peel waste, an underexplored agricultural by-product, as a sustainable and eco-friendly energy source. Processed peels were utilized as the electrolyte in single-, dual-, and triple-beaker configurations, with voltage and current outputs systematically evaluated. Results revealed a positive correlation between peel mass and voltage generation, increasing from 0.987 V at 10 g to 0.996 V at 30 g. The bio-battery successfully powered small electronic devices such as LED bulbs, demonstrating its functional viability. By transforming fruit waste into a renewable energy material, this work provides new insights into waste-to-energy applications and highlights the untapped potential of mangosteen peel in advancing green technology innovation.
