Iot-Based Monitoring and Alert System for Carrageenan Production in Coastal Village

Carrageenan is a polysaccharide compound extracted from seaweed that is widely cultivated in Sumenep waters, has a higher economic value. The process of processing seaweed into carrageenan is carried out by the extraction process at a temperature of about 80-90° C which takes several hours until the carrageenan is completely dissolved and the drying process in the oven until it becomes dry material. Both processes greatly affect the quality of the processed carrageenan. Therefore, real-time and continuous monitoring is required so that the quality can be maintained properly. With the processing site located in a coastal area far from the city centre, an Internet of Things (IoT)-based monitoring and alert system is proposed that can send real-time information. The data obtained can be used as a reference for alerts to operators in the control room through a web that can be accessed easily. The system employs ESP32 board, Thermocouple Type K sensor, SCT-013-010 sensor, which transmits data to Firebase real-time database where the data is stored. A web-based User Interface is created to display data and alerts with easier access. The system applied to carrageenan processing in coastal areas shows the usefulness of monitoring and warning against excessive temperatures.
