Abstract
Brackish water and river water have the potential as an alternative renewable energy source. Their electrical studies have been successfully conducted using the electrochemical principle of voltaic cells, by making electrode pairs arranged in series in 20 rectangular squares. Electrodes used are copper (Cu), and zinc (Zn), while as an electrolyte is some brackish water and river water. The characteristic of the electrolyte material is known by measuring the voltage and current flowing on the LED (1.2 watt) placed on the electrode cell circuit. Taking measurement data is done for three days with 2 hour interval. The results of measurement and analysis for Cu-Zn electrode combinations have shown that brackish water has greater electrical power than river water, with a ratio of 12.008: 5.84 (day one) and 1.752: 0.572 (third day). This value also shows that brackish water as electrolyte solution has been able to produce energy to turn on the LED for 72 hours with an average value of LED intensity of 322.8 lux.
