SISTEM IOT UNTUK MONITORING DEBIT AIR SUNGAI MENGGUNAKAN PROTOKOL MQTT

Flood disasters are a recurring issue in Indonesia, particularly in densely populated areas near rivers. To address this problem, this study develops a river water discharge monitoring system based on the Internet of Things (IoT) using the MQTT protocol. Sensor data is transmitted via a GSM module to an MQTT Broker, then visualized on a real-time dashboard and sent as notifications. This research analyzes the performance of the MQTT protocol under various network conditions by measuring Quality of Service (QoS) parameters, such as latency, throughput, and reliability. The results show that MQTT delivers stable performance in good network conditions, while unstable networks require QoS level adjustments to maintain optimal system functionality. Moreover, optimizing MQTT QoS settings can enhance data transmission efficiency in the monitoring system.
Further improvements can be achieved by integrating alternative communication technologies such as LoRa and implementing AI-based analytics for proactive flood prediction. This approach is expected to improve flood disaster preparedness more effectively and in a timely manner.
