Sistem Pertanian Hidroponik Terintegrasi Menggunakan IOT pada Sayuran Kangkung

Hydroponics is a method of cultivating plants without using soil, but with nutrient-rich nutrient solutions. This research aims to design and implement an integrated hydroponic farming system using the Internet of Things (IoT) on kale plants, so that monitoring and control of growth parameters can be carried out in real-time and efficiently. The system built utilizes pH sensors, Electrical Conductivity (EC) sensors, temperature sensors, and ESP8266 NodeMCU microcontrollers as control centers. The measurement data is sent to the Blynk platform to be displayed via smartphone, allowing users to monitor nutritional and environmental conditions remotely. Research methods include hardware design, microcontroller programming, and system testing during kale growth. The test results showed that the system was able to detect changes in pH, EC, and temperature of the solution with sufficient accuracy, as well as provide
notifications when parameters are outside the ideal limits. This IoT-based monitoring simplifies the maintenance process, reduces the risk of nutritional errors, and improves resource utilization efficiency. Thus, this IoT-integrated hydroponic system can be a practical and effective solution to support the cultivation of leafy vegetables such as kale, both on a household and commercial scale.
