Abstract

Electrical installations on ships are highly susceptible to damage due to environmental factors such as high humidity and extreme temperature fluctuations, which can accelerate corrosion and increase the risk of short circuits. Therefore, an effective monitoring system is required to detect environmental conditions early, ensuring safe navigation and ship operations. This research aims to create and develop a prototype of a temperature and humidity monitoring system using Internet of Things (IoT) technology as a preventive measure against damage to electrical installations. The research method used is Research and Development (R&D) employing a prototyping model. This model consists of several stages: planning, design (covering hardware and software), and testing. The system utilizes an ESP32 microcontroller as the main processing component, a DHT22 sensor for data acquisition, and the Blynk application along with a 16x2 LCD screen to display real-time results. The research results indicate that the developed prototype is capable of accurately monitoring temperature and humidity parameters. The feasibility level obtained from expert validation reached 92%, while the practicality level provided by seafarer respondents reached 91.2%. The system is highly effective in providing early warnings through buzzer sounds and smartphone notifications, thereby assisting in problem prevention before they occur and enhancing the performance and reliability of the electrical system on board.
