PERANCANGAN SISTEM OZONIZER UNTUK PENDUKUNG LINGKUNGAN HIDUP IKAN YANG DILENGKAPI DENGAN KONTROL WAKTU MENGGUNAKAN MIKROKONTROLER ATMEGA8535

Abstract

In this research, was design ozone generating system equipped with time control. It is intended to support the growth and development of fish breeding. In this system, ozone generated by discharge plasma at atmospheric conditions. Electrode system using a 25.7 cm long tube geometry and an outer diameter of 6.7 cm. At the anode using Stainless Steel wire length of 1.5 m were formed spiral along 14 cm. The dielectric tube made of pyrex glass with a diameter of 3.8 cm and height 14cm. The gap’s range between the surface of the dielectric tube with the surface of the cathode tube is 0.10 cm. The discharge voltage used about 0.045 to 13.50 kV with a frequency about 884-891 Hz. The identification of ozone gas is characterized by the odor smell of ozone and chemical analysis test results used binder chemical ozan with Potassium dihydrogen bonded Phosepate (KH2PO4), Sodium Hydrogen Phosepate (Na2HPO4), and Potassium Iodide (KI). The concentration of ozone generated about 0.036 to 8.668 ppm. The magnitude of the high voltage can be adjusted by turning the potentiometer located on the front Ozonizer to adjust the amount of generated ozone concentration. The control system is used a microcontroller for automatic setting time duration ozone production and ozone timer to run the ozone system. Keywords: Ozone, Ozonizer, Tube Reactors, Discharge Plasma.
