Abstract

This study presents the development of an Internet of Things (IoT)-based monitoring system for seawater pH and ballast water level on an Unmanned Surface Vehicle (USV). The increasing use of USVs in maritime operations requires a monitoring system capable of observing environmental conditions and vessel stability in real time. The proposed system integrates an ESP32 microcontroller, an Analog DFRobot pH sensor, and an HC-SR04 ultrasonic sensor. Sensor data are transmitted using the MQTT protocol through a Wi-Fi network and visualized on a Node-RED dashboard. Experimental results demonstrate that the developed system successfully acquires, transmits, and displays seawater pH and ballast water level data in real time. The integration of both monitoring parameters within a single IoT platform provides an effective solution for supporting autonomous maritime operations and environmental monitoring.

Abstract

A conveyor is a tool with a large rubber band arranged transversely between two pulleys at a constant speed as a transporter of solid material in this case coal with the provisions of the permitted amount. Damage to the conveyor tool has a major impact on the smooth running of a coal loading and unloading process, so a coal monitoring tool was designed using an ESP32 microcontroller-based data logger. The purpose of this study is to find out how to design a coal load monitoring tool based on a data logger using the Research and Development (R&D) method type ADDIE. Using the following types of testing: static and dynamic. The research results show that the load monitoring system based on a load cell and ESP32 microcontroller demonstrates high accuracy, with a reading deviation of less than 2% from the actual weight. The system is also considered effective, as it can detect loads, adjust the hatch door angle, and transmit data to Google Spreadsheet in real-time without disruptions. Its ability to adapt to varying loads indicates that the prototype operates stably, responsively, and in accordance with the design objectives.

Abstract

A crane is a tool used to make it easier and easier to move and lift goods. This research aims to find a solution when the Joy Stick experiences sudden troubleshooting, how to overcome it, and prevent accidents while working. The creation of this tool is a miniature ship crane using a 220V Ac motor where the fan belt is the connecting part of the movement and can be controlled via a Joy stick. The design of this AC motor control system entirely uses the ESP32 microcontroller as the brain to be able to carry out slewing, luffing and hoisting movements. Researchers used research and development research methods to create and develop this crane prototype with the aim of producing and developing a crane prototype that is effective, efficient and easier to maintain. The test results of this prototype can carry out slewing movements to the left and right with a limit of 800, luffing movements upwards with a limit of 800 and hoisting.

Abstract

The safety and protection of the hydraulic crane is an important aspect that ensures the charging operation runs safely and efficiently, this study aims to provide protection against crane damage and minimize work accidents by providing overload detection sensors using loadcells and hx711 as the primary sensor in charging this device. This tool is a miniature crane that uses a servo motor and a DC motor as a replacement for the hydraulic on the crane. Where the same function, to move the arm of the crane and crane can rotate left, right, and up. The researchers used prototype methods to build and develop prototypes of cranes. To monitor this control system, use ESP32 as the transmitter and receiver of the joystick motion response. The received data will be processed and displayed on the LCD. Testing this device can detect how much load is lifted and detect if the load is over lifted, the device's operating system will lower the load again if overloaded.

Abstract

On tanker ships, boilers play a crucial role in providing steam for various operational needs. The stability and reliability of the temperature and water level control system are essential to maintaining efficiency and safety on board. This research aims to design and develop an automatic control system using Outseal PLC and HMI to regulate the temperature and water level in boilers. The research method used is experimental, where the system is designed, developed, and tested to evaluate its effectiveness.The system design involves a DS18B20 sensor to detect temperature, an ultrasonic sensor to measure water levels, and a heater as a heating actuator. The Outseal PLC functions as the main control unit, while the HMI facilitates monitoring and operation. The results show that the system can control water temperature within the desired range, with an average setpoint achievement time of 3.5 to 4.5 minutes. Additionally, the water level control system operates in real-time with a high level of accuracy.The implementation of this automatic control system based on Outseal PLC and HMI is expected to improve operational efficiency and safety on tanker ships. Moreover, it can serve as a reference for developing similar control systems in the maritime industry.
