WULUH STAR FRUIT (Averrhoa Bilimbi) AS A SOURCE OF ENERGY IN GALVANI CELLS
Keywords:
Starfruit, electrolyte, galvanic cellAbstract
In this life, electricity is one of the most important things to meet human needs. After basic needs such as food, clothing and shelter, electricity is an important need that cannot be separated from human life, without electricity, of course the three basic needs above will not be fulfilled. Galvani cells are cells that produce electric current, there are three components, namely anode, cathode and electrolyte. Electrolytes can be acids, salts, or amphoteric compounds. The purposes of this study include (1) to find out how to use starfruit, (2) to determine the effect of the amount of starfruit (Averrhoa bilimbi) on the electric current, and the resulting pH, (3) to determine the electrical conductivity in trials on LED light. The method used is an experimental method using starfruit as the research object. The research results inform that a single Galvani cell system can produce a voltage and electric current of 0.22 volts and 3.04 mA. After conducting research, it can be concluded that starfruit (Averrhoa bilimbi) can be used as an electrolyte solution in the Galvani cell system to produce electrical energy.
