Design Of A Wi-Fi Based Monitoring And Control System For Milkfish Pond Water Quality (Case Study: Pokdakan Tani Sejahtera)

Abstract

The Fish Cultivation Group (POKDAKAN) of Prosperous Farmers is one of the groups that cultivate brackish water milkfish in Kedanyang village. Based on the information received from the results of observations and interviews with the pond management, the main problem when cultivating milkfish is that water parameters (pH, Total Dissolved Solid, and temperature) are not monitored properly. Pond farmers cannot monitor every water parameter, whether in good or bad condition, because there is no adequate monitoring and only rely on looking at the color of the pond water.  Weather factors are also a challenge during the rainy season, changes in water conditions can occur extremely. Based on the existing problems, the research that will be carried out is to develop existing research by using the necessary parameters such as salt content, water pH, and water temperature as well as to control automatically if there are problems that occur in the pond. By using the test parameters on the system, the pH level is generally within an acceptable range but with occasional fluctuations. Temperature variations tend to be within a narrow range unless there is an isolated drop. The TDS level is stable with occasional deviations, especially the one recorded on June 27 the testing on the website has been successful and the features are working as intended. The success rate of this system is 99.997%.
