Abstract

Fire hazards could be happened anywhere, it could be on a land (houses, buildings, forests, etc.) or on the sea (ships). This incident was occurred at KM Artamina Jaya. Fire prevention action performed by eliminate three elements of oxidation reaction, these are: fuel, oxygen, and heat. A method to break the three elements is spray water to the fire source. Existing or common fix fire distinguish usually use water spray or sprinkle. It takes a large amount of water to extinguish the fire and it conduce wets areas where not affected by fire. So that this research was invent to design a water-saving fire extinguish system based on Arduino Mega microcontroller. This study use 5-channel infrared flame sensors to detect the location of a fire and a DC motor sensor to spray water. By using 5-channel infrared flame sensors, the Arduino Mega microcontroller can determine which DC motor to spray water. The focus of this research is how to activate the fire extinguish pump or water sprayer according to the channel on the infrared flame sensor, which detects the source of the fire, and the system can activate more than one pump.

Abstract

Indonesia as a maritime nation with vast and strategic oceanic territory, continues to develop efficient and innovative ship technologies. This research focuses on the design and construction of a speed monitoring system for a trimaran vessel using the Pixhawk controller. The system integrates a Pixhawk autopilot unit as the main controller, an STM32 microcontroller for processing, dual BLDC motors, an internal combustion engine (ICE), and a remote control system. The Internet of Things (IoT) platform is employed for real-time data logging and monitoring. Experimental tests were conducted on five reference speed levels slow patrol, reconnaissance, medium patrol, cruising, and chase modes. Quantitative results show that the system achieved rapid response times at medium speeds, with stable operation and an average delay below 0.5 seconds. At high speeds, however, stability decreased by 15–20% due to environmental and load variations. Remote control communication maintained stable performance up to 210 meters with obstructions and 280 meters without obstacles. The results demonstrate that the system effectively supports real-time speed monitoring for trimaran vessels. The novelty of this study lies in the integration of hybrid propulsion and adaptive control within an IoT-based Pixhawk monitoring system, contributing to advancements in smart maritime technology.
