Abstract

Water is a natural resource that plays the greatest role in the life of living things in water, one of which is fish. Water hygiene is very important for the health of the fish. Water hygiene is the most important thing in fish farming. Because, it can affect health factors and interfere with the growth of fish. One of the factors affecting the health of fish is water quality. One of them is in the form of dissolved solids or what is commonly called nutrient content in water. To maintain water quality the cultivator must periodically check the moisture content. It will waste time as well as costs. Therefore, a tool is needed that can control the quality and nutrition of freshwater fish ponds that can maintain the quality of fish pond water every day such as controlling TDS levels in pond water. This study aims to design a water nutrient content control system using TDS sensors, Arduino Uno, relay, LCD, Water pumps, TDS sensor modules and ESP8266 WiFi Modules. Once installed esp 8266 will look for wifi signal first and the tool will run. The TDS sensor will detect the conductivity level in the water and will then send a signal to the TDS module. The TDS module will condition the signal and then send it to the arduino and it will be displayed on the LCD. The ESP8266 WiFi module will transmit the same display on the LCD to the smartphone via the Blynk app. If the TDS level in the pool exceeds 600 ppm, the water pump will start. Because the TDS level in the pool that is still suitable for use is between 900-1100 ppm. So that the water is not too dirty when reaching the figure of 1100 ppm, therefore a limit is given to the 600 ppm program.
