Abstract

Fertilizer management in oil palm plantations still faces security and stock-recording accuracy challenges because it is largely carried out manually using mechanical locks and paper-based records. This study designs and implements a prototype Internet of Things (IoT)-based security and stock monitoring system that integrates RFID authentication to control warehouse access with a load cell sensor to monitor changes in fertilizer weight as a stock indicator. The entire process is controlled by an ESP32-S microcontroller, with data transmitted in real time to a Firebase Realtime Database, displayed on a Kodular-based Android application, and automatically logged to Microsoft Excel. The research method used is Research and Development (R&D) through the stages of needs analysis, hardware and software design, implementation, and system testing. The test results show that the system is able to perform RFID authentication correctly, accurately read fertilizer weight changes in the 2-10 kg range, display information on the LCD and Android application in real time with an average data update time of 1.1-1.3 seconds, and automatically log all access activities. All ten hardware and software components tested functioned according to the design. This system is expected to improve the security, transparency, and efficiency of fertilizer management in oil palm plantation warehouses
