From the total municipal organic waste, around 60% are vegetables and 40% are leaves, fruit peels and leftovers. In fruits contain substances such as ascorbic acid, citric acid and NADH (Nicotinamide Adenosine Dinucleotide Hydrogen, that produces cell energy), which under certain conditions these chemicals act as electrolytes. From the electrical properties that contain a lot of electrolytes from fruit and vegetable waste can be used as a renewable alternative energy source in the form of bio -batteries as a substitute for conventional batteries. The development of waste fruits and vegetables as bio-batteries will contribute greatly to the world of science in particular, and society in general. Data collection from previous studies was carried out and then analyzed based on existing parameters. There are various parameters related to the electrical properties of fruits and vegetables. Different types of fruits and vegetables produce different currents and voltages. Fruits and vegetables have different pH (acidity), where pH is inversely proportional to current and voltage. In addition, the type of electrode used also affects the electrical properties. The distance between electrodes is inversely proportional to current and voltage in fruit and vegetable waste. Installing bio-batteries in series and parallel can increase current and voltage. Bio-batteries with a higher voltage will produce longer LED flash times.
