Abstract

General Background Maritime tourism development increases the use of large vessels such as phinisi cruise ships which have operational safety challenges. Specific Background The large structure of phinisi ships creates blind spots that can lead to potential collisions with smaller vessels. Knowledge Gap Existing navigation systems have limited capability in detecting objects within blind spot areas in real-time. Aims This study aims to design and implement a blind spot sensing alert system using a laser distance sensor based on Arduino Uno. Results The developed system is capable of detecting object presence within blind spot areas and providing warning signals to assist navigation awareness. Novelty The integration of laser distance sensing with a simple microcontroller-based system provides a practical solution for blind spot monitoring on traditional vessels. Implications This system can support maritime safety by reducing collision risk and can be further developed for wider implementation in similar ship types. Keywords: Blind Spot Detection, Phinisi Ship, Laser Distance Sensor, Arduino Uno, Maritime Safety Key Findings Highlights System identifies object presence in blind navigation areas Warning mechanism supports real-time operator awareness Prototype demonstrates practical implementation on traditional vessel

Abstract

General Background: Hygiene of baby feeding equipment is essential due to infants’ low immunity and high risk of bacterial contamination. Specific Background: Conventional cleaning and drying methods are often ineffective and less hygienic, while existing sterilization systems lack integrated remote monitoring. Knowledge Gap: Previous studies have not fully integrated UV-C sterilization, heating-based drying, and Internet of Things control in a single system. Aims: This study aims to develop an IoT-based UV-C sterilization device using ESP32 to monitor and control sterilization and drying processes. Results: The drying system reduced moisture to a completely dry state, while sterilization testing showed bacterial counts below SNI thresholds. The IoT system operated up to 60.2 km with an average delay of 4.86 seconds, and the DS18B20 sensor achieved an average error of 0.25°C. Novelty: The integration of UV-C sterilization, heating drying, and long-distance IoT control with real-time monitoring represents the main contribution. Implications: This system provides a practical and hygienic solution for maintaining baby equipment cleanliness with reliable remote operation Keywords: Uv C Sterilization, Internet of Things, Esp32, Baby Equipment, Temperature Sensor Key Findings Highlights Drying process achieves complete moisture removal after extended duration Bacterial testing confirms compliance with microbiological safety standards Remote operation remains stable across multiple long-distance locations
