Abstract

Bio-battery is an alternative natural energy source that utilizes organic compounds to generate electricity. This research uses coffee grounds as an environmentally friendly electrolyte paste. This study aims to identify and analyze the current and voltage produced by the bio batteries with the durability of bio batteries made from Arabica coffee grounds based on electrode distance and dryness level. The method used is a direct measurement of coffee grounds using copper (Cu) and zinc (Zn) as electrodes, further testing of the output current and voltage is carried out every 24 hours. The results showed that Arabica coffee grounds produce a maximum voltage of 1.01 V, a current of 0.49 mA and a power of 0.42 W. Based on these results, Arabica coffee grounds have the potential to be used as bio batteries.
