PROTOTYPE OF FEEDING CONTROL SYSTEM, AUTOMATIC HARVEST USING BLYNK APPLICATION BASED ON ARDUINO UNO R3 MICROCONTROLLER AND NODEMCU

Abstract

Nila is a fish that is quite in demand. This fish is widely cultivated by the people of Indonesia, but the cultivation technique still uses traditional methods. The demand for high-protein fish makes farmers have to think about the best way to produce as much fish as possible. Factors to consider are feed, environmental quality and harvesting process. In the care of value fish, it is necessary to have a process of feeding fish. The distribution of feed must be given evenly so that the growth of fish is evenly distributed. The pH level in fish maintenance must be considered so that fish. In terms of harvesting usually requires a lot of manpower, in this study an automatic system for harvesting fish is made. With the help of microcontroller and telecommunications technology can be applied in the cultivation process. Arduino is used as the main processor using two microcontrollers, namely Arduino UNO and NodeMCU directly integrated into smartphones, which makes it easy for farmers to control the quality of their livestock products. Two microcontrollers connected by serial communication. The Blynk application as a user interface for monitoring and controlling so that this tool can make farmers not spend a lot of energy  farming process.
