Automation of water circulation regulation and nutritional administration in catfish cultivation ponds with Bioflocculation technology

Many catfish cultivators in Indonesia have failed due to lack of attention the quality water used aquaculture ponds. Water is very influential on farming system with biofloc technology, has most important role for survival catfish. This research periodically measures level turbidity and pH water, then readings from sensor will be processed by Arduino Uno which displayed LCD. In addition, this tool can also schedule provision nutrients as desired able perform automatic changes according conditions pond, if pond exceed existing threshold, it activate drain pump increase. The accuracy acidity (pH) an rate 96.21% good, a standard deviation 2.49. 0.133. So designed make easier take care pond. hope that making overcome or mortality among cultivators.
