Fish Feeding Control Management and Checking Water Quality Application Using MQTT Techniques.

Abstract

The government has supported the development of freshwater fisheries or local fisheries from Fisheries Statistics Group, Fisheries Development Policy and Planning Division of the Department of Fisheries. In the development of the local area, freshwater fishing is encouraged in the group of 3 species of fish: Tilapia, Catfish and Tapia. The problems encountered by freshwater fisheries are water quality and feeding procedures in freshwater fisheries that provide food with not actual proportional. Therefore, the water quality deteriorates as well. The researchers then found a way to manage fish feeding automatically and check water quality through the application by using MQT technology to manage work and monitor the data to suit freshwater fishing to the quality of growth and properly control the amount of food to reduce food costs. The research was divided into two parts: hardware and software. Hardware is an M.C.U. node with a relay used to control the motor. In addition, there is a PH sensor module and waterproof temperature sensor. As for software, Python programming serves as a platform for developing applications used to communicate with users. In the research, it will be applied to freshwater fishing groups to feed catfish. As a result, fish have a 95 percent survival rate from normal with a 70 percent survival rate. This can increase the survival rate of catfish in kindergarten and reduce labor consumption in fisheries by up to 60% as data can be checked and controlled through the application.
