Abstract

This study aims to design and develop an Internet of Things (IoT)-based electrical energy source monitoring system for ships to support the utilization of renewable energy, particularly Wind Power Generation (WPG). The background of this research is the continued use of manual monitoring systems, which are less effective, prone to recording errors, and unable to provide real-time data monitoring. The developed system utilizes a ZMPT101B voltage sensor, an ACS712 current sensor, an ESP32 microcontroller, a 20×4 I2C LCD, and the Node-RED platform for data visualization and storage. This study employs a quantitative experimental method, including hardware design, software development, and static and dynamic testing. Testing was conducted at two locations, namely the Merchant Marine Polytechnic of Surabaya and Kenjeran Beach, Surabaya, for 8 hours. The results show that the system performed successfully, displaying real-time data through both the LCD and Node-RED dashboard while also enabling automatic data logging without data loss. The ACS712 sensor exhibited an error range of 2.38%–7.14%, while the ZMPT101B sensor showed an average error of approximately 0.8%. Based on these results, the developed IoT-based monitoring system is considered feasible for shipboard electrical monitoring and has the potential to improve operational efficiency in electrical monitoring activities.

Abstract

Sustainable maritime transportation requires electrical systems that are reliable, energy-efficient, and capable of integrating cleaner energy sources. This study develops and evaluates a small-scale hybrid power prototype that combines a 50 Wp photovoltaic (PV) source as the renewable-energy component with a mini steam power source as a complementary generator, using an ESP32 microcontroller, INA219 sensors, MPPT control, a buck-boost converter, and relay-based automatic switching. The experimental program included static component verification and dynamic tests under changing solar irradiance, steam pressure, source-transfer conditions, smartphone monitoring, and 180-minute battery-charging cycles. The PV source produced 11.1–19.7 V and 0.8–2.6 A depending on weather conditions, while the mini steam source became stable from approximately 20 psi and produced 23.3–24.5 V and 2.2–2.5 A between 20 and 50 psi. Automatic source switching occurred in approximately 0.2 s in all five trials. Both charging paths raised battery voltage to 12.8 V at 90 min, after which charging was automatically disconnected. These results show that renewable-energy utilization can be strengthened by hybrid-source coordination, real-time monitoring, and energy storage to support continuity of power for maritime transportation. From a Vessel-to-Grid (V2G) perspective, the prototype demonstrates enabling functions at the onboard energy-management level, but bidirectional power export to an external grid was not tested and remains a subject for further development. .
