Maintaining Water Quality in Aquaculture under IoT System
Maintaining water quality is an important factor in a healthy aquaculture environment. Its main objectives are: water temperature, pH, dissolved oxygen (DO), salinity, turbidity, ammonia nitrogen, chemical oxygen demand (COD), biochemical oxygen demand (BOD), the parameters that strongly associated to the incubation environment of aquaculture.
According to Wibisono (2019), three variables significantly affect Vaname Shrimp cultivation because they impact water quality, including temperature, pH, and salinity. Temperature significantly affects the growth of shrimp culture. If there is an extreme increase in temperature, it will result in the death of shrimp. Shrimp fry can grow well in warm water, but the older the shrimp, the lower the optimum temperature. The suitable temperature for the growth of vaname shrimp is 22-30°C, while the shrimp is stressed when exposed to temperatures of 15-22°C and 22-30°C. pH serves as a chemical and biological indicator in aquatic metabolism. If the pH is low, the dissolved oxygen content is low. This can
decrease oxygen consumption, reduce appetite, increase activity, and vice versa. Shrimp culture works well in water with a pH of 6.5-9.0 and an optimal range of pH 7.5-8.7. Salinity (salt content) is the environmental change from standard salinity medium (30 ppt) to low salinity stage. The decrease in salinity resulted in lower growth and survival of shrimp.
Manually controlling water quality can give less accurate results or solely on feeling. The utilization of information and communication technology is an alternative solution that adapts current technology to minimize the power of farmers in managing shrimp farming. Maintaining water quality will be a factor for shrimp growth rapidly with a low mortality rate.
Several studies on the design of water quality monitoring have been developed, such as incorporating microcontroller and IoT technology to produce real-time, objective information and display the circulation process when water quality changes from normal conditions in the Vaname Shrimp cultivation prototype. Another thing was done used a microcontroller and sensors (pH and temperature) and ultrasonic sensors to measure the water level and displayed it on Telegram Messenger. There is also the use of data loggers and IoT connected to the internet to send all water quality monitoring data to a Google database service called Firebase, which can be accessed through an android-based monitoring application.
Some of the advantages of using IoT for water quality management include improving the water quality management are reducing the operational cost of the shrimp aquaculture by using an automatic aeration system . Also, it helps farmers maintain the water quality precisely to produce high-quality shrimp crops toward the precision aquaculture concepts by using PFF (Precision Fish Farming).
