Sistem Smart Farming Cabai dengan Rule-Based System Node-RED dan Berbasis Internet of Things

This study aims to design and implement a Smart farming system based on the Internet of Things (IoT) using a Rule-Based System (RBS) approach for the cultivation of Japlak chili at Dafrot Farm, Tasikmalaya Regency. The research adopts a Research and Development (R&D) method consisting of literature review, needs analysis, system design, hardware and software development, as well as system testing and evaluation. The system is developed using an ESP32 microcontroller and equipped with DHT11, DS18B20, YL-69 soil moisture sensor, and MH-RD rain sensor. Node-RED serves as the core platform for data processing and rule-based decision-making using IF-THEN logic. Data is transmitted via the MQTT protocol and monitored in real-time through the IoT MQTT Panel application. The research findings indicate that the system can accurately monitor environmental parameters and provide appropriate automatic responses to certain conditions, such as low soil moisture or rainfall. The water pump is activated automatically when soil moisture drops below 60% under clear weather conditions and is deactivated when moisture exceeds 68% or rain is detected. In addition to the automatic mode, manual control is also available via the dashboard and mobile application. The system demonstrated stable and responsive performance during field observation.
