Sistem Monitoring Proses Pengomposan untuk Optimalisasi Kualitas Kompos berbasis Internet of Things

Abstract

The composting process requires regular monitoring of temperature and moisture; however, composting sites without internet access limit real-time and remote monitoring capabilities. This study aims to design an Internet of Things (IoT)-based monitoring and control system capable of transmitting data from the composting site to a gateway, storing the data in a database, and displaying composting conditions in real time. The method involved the design and implementation of hardware and software using an ESP32, DS18B20 temperature sensor, moisture sensor, NRF24L01 as a transmitter-receiver communication module, 20×4 LCD, MySQL server, and web application. Testing was conducted to evaluate communication range and pump control responses based on temperature and moisture conditions. The results showed that communication was successfully maintained over a distance of up to 100 m in open areas and up to 65 m indoors. The nitrogen pump was activated at a temperature of 28.3 °C and deactivated at 43.9 °C and 52.5 °C. The water pump was activated at a moisture level of 36% and deactivated at 57% and 66%. The developed system successfully integrated automatic monitoring and control functions, enabling real-time monitoring and automated control of the composting process
