E-Ox Level: Sustainability Test of Data Storage System and Performance Test on Closed System Fish Pond

Abstract

Fish farming using a closed system is very susceptible to death in a chain because it does not change the water so that the water quality decreases relatively quickly. To solve this problem, they generally use a circulation pump machine and an aerator machine to add oxygen levels, so that water quality remains stable. E-Ox Level is a research technology that has been tested and is able to work continuously. Its function is to monitor water quality and control the aerator machine's on and off activity based on timing and dissolved oxygen levels. The power source used by E-Ox Level is solar energy. So that this technology can save energy and is environmentally friendly, because it does not use PLN electricity. This research is an advanced stage process from the previous E-Ox Level technology design engineering. The purpose of this research is to see the ability of E-Ox Level technology when monitoring and storing water quality data continuously, as well as controlling the stability of fish pond water quality conditions. so that it can produce fish that are better than natural treatments. The method used in this research is to make observations in the Budidkdamber pond for three months with the stages of seeing the suitability of the data displayed on the LCD, and stored on the SD Card, as well as comparing the growth of catfish in ponds with E-Ox Level installed, AC Aerator installed, and the control pool. Next, observe the harvest in the biofloc pond for three months. From the observations in the Budikdamber pond, the complete data is stored on the SD Card from January 25 to April 8, 2021. Fish growth using E-Ox Level and AC Aerator is better and faster than the control pond. Fish yields in biofloc fish ponds that were paired with E-Ox Level experienced an increase in harvest weight of catfish by 0.17% from the previous period, when the pond did not use E-Ox Level.
