Pemanfaatan Kulit Nanas Dan Tomat Busuk Pada Aplikasi Biobaterai Ramah Lingkungan

Abstract

This research addresses the issue of waste management and the need for alternative energy by developing environmentally friendly biobatteries. The main objective of the research is to utilize a combination of pineapple peel and rotten tomato waste as electrolytes, as well as to reuse carbon from used batteries to improve the efficiency of electrochemical reactions. The experimental method involved making electrolytes from pineapple peel powder and rotten tomato juice with varying concentrations, which were then mixed with carbon from used batteries in different ratios. The performance of the biobatteries was analyzed based on the current, voltage, and electrical power generated. The test results showed that with a single electrolyte, 100% tomato had better performance than 100% pineapple peel. The most optimal composition was found in the mixture variation (25% pineapple peel + 75% tomato) with a ratio of 50% : 50% carbon, which produced a voltage of 1.43 V, a current 4.9 mA, and the highest power reaching 7.007 mW. This study concludes that the combination of organic waste and used carbon has great potential as a stable alternative energy source and is capable of reducing environmental pollution.
