Abstract

In catfish cultivation, fish growth conditions will be optimal if they are in the pH value range of 6-9. This water quality problem becomes a major problem for catfish farmers in the Cadek area of Aceh Besar district, when the water pH is not normal. The developing internet of things (IoT) technology can really help or make it easier for farmers to control water pH. The aim of this research is to design a water pH monitoring tool using IoT-based tools. This research model applies the 4D model, namely define, design, develop, disseminate. some of the equipment used is NodeMCU, pH sensor, water pump relay, Blink application and pHmeter. The results of the feasibility of this tool carried out by 2 expert validators in the field of electrical engineering were obtained in the very feasible category. The next stage was to test the device 10 times using the Blynk application and a pHmeter. In the Blynk application, the average pH value read is 5.67. Meanwhile, when measured with a pHmeter, the average pH value read was 5.92. This designed tool can provide pH values regardless of position without having to be close to the catfish pond, so that farmers can check the pH of the pond water from a distance. It can be concluded that good accuracy of the fish pond acidity test equipment has been obtained and is a positive step in ensuring the health and survival of fish as well as operational efficiency.
