Abstract

Danova, F. A. 2025. "Design of Pump Control and Water Level Monitoring System on the Expansion Tank of MT. SC COMMANDER LVII Vessel" Overflow from expansion tanks on ships can lead to significant operational and safety losses. On the MT. SC COMMANDER LVII vessel, manual filling of the expansion tank often results in overflow due to the remote position of the filling valve relative to the tank and lack of real-time monitoring during the process. This issue poses a risk of damaging electrical systems and reducing the efficiency of the ship’s cooling system. This research aims to design an automatic pump control and water level monitoring system based on the ESP32 microcontroller and HC-SR04 ultrasonic sensor using an Internet of Things (IoT) approach, to detect and control the water level in real-time. The research follows the Research and Development (R&D) methodology with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), including expert validation and user testing stages. The system features an I2C LCD for local display, a buzzer as an alarm indicator, and the Blynk application for remote monitoring. Validation by experts and testing by 20 marine engineering cadets demonstrated that the system is practical and effective for operational use. Implementation of this system has proven effective in minimizing the risk of overflow and low water levels in the expansion tank, thus improving the ship’s operational safety and efficiency. This system also holds potential for further development through additional features such as data logging and integration with other support sensors.
