Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's leading plantation commodities whose productivity depends on soil pH and moisture. This study aims to develop an Internet of Things (IoT)-based monitoring system capable of measuring soil pH and soil moisture in real time while providing fertilizer recommendations. The ADDIE model was adopted consisting of Analysis, Design, Development, Implementation, and Evaluation. The system integrates ESP32, soil pH sensor, soil moisture sensor, Firebase, and a Kodular-based Android application. Experimental results indicate that the proposed system performs real-time monitoring and provides fertilizer recommendations according to predefined rules.
