Bachelora using air by using solar-degree angle under the sun to reduce the electricity consumption is to study the efficiency of the electricity production of the panel. Solar cells to be able to adjust the angle under the sun. The test system can control the solar panel to adjust the angle under the sun by using a microcontroller to control the LDR 1 with LDR 2 is a sensor on the drive, one does not get the DC motor will rotate. At the same experiments with light pressure of up to 20.21 volt electric current that measured a maximum is 3.14 amperes and power lead to systems that treat wastewater. By using aeration pump oxygen into water quality to increase the pH value of water is best 6-6.5 pH value of water as clean as possible.
