Abstract

Optimization methods are crucial methods in a process because optimization methods can solve complex problems. One of the most effective optimization methods to achieve optimal solutions is Particle Swarm Optimization (PSO), an algorithm inspired by the social behavior of animals. Where, the PSO algorithm is a particle (parable an animal) that has been initialized will move continuously updating its position based on a combination of two factors, namely the attraction towards the individual's best position (pBest) and the attraction towards the global best position (gBest) until it reaches the position optimal. Particle movement is influenced by three main control parameters, namely cognitive coefficient (c1), social coefficient (c2), and inertial weight (ω) in order to produce optimal values ​​without being trapped in local solutions. The advantages of PSO compared to other optimal methods such as the Firefly Algorithm (FA) and Gray Wolf Optimizer (GWO) are its convergence speed and ability to handle non-linear problems with noise. This makes PSO good for applying to complex problems such as solving non-linear mathematical model problems, optimizing fuzzy controllers, optimizing exhaust gas emission parameters and engine performance on ships.

Abstract

Electric motors are vital components in ship operations, particularly within sewage pump systems. However, continuous workloads often trigger temperature increases that lead to a decline in motor performance. This study aims to monitor motor temperature in real-time and analyze its effect on rotational speed (RPM) efficiency. In previous research, data on speed parameters and motor operating conditions were obtained, displayed, and analyzed visually and structurally using LabVIEW. The results showed that this system was effective in monitoring   motor operating conditions to prevent performance disruptions. However, the developed monitoring   system was still offline and did not support real-time remote monitoring  . Future research was recommended to integrate this system with an IoT-based network to support remote surveillance.The research methodology was conducted through a 30-minute dynamic test using an ESP32 microcontroller-based thermocouple sensor and a Node-RED dashboard as the monitoring   unit. The obtained data were analyzed using the Simple Linear Regression statistical method. The test results demonstrated a gradual temperature rise from 35°C to 63°C at the 30th minute, which remains within the safe category but requires special attention. This equation exhibits a significant negative correlation, where every 1°C increase in temperature results in performance degradation, specifically a decrease in motor speed by -2.71 RPM. This decline is caused by the increased electrical resistivity in the windings and changes in lubricant viscosity due to overheating. This system is proven effective as a preventive maintenance tool to prevent winding insulation damage and extend the operational lifespan of motors onboard ships.

Abstract

A hovercraft is a vehicle that utilizes air pressure inside the skirt to produce an air cushion to support the entire load. It carries a ship that runs on an air cushion. Hovercrafts use propeller or fan rotation to move the hovercraft. However, there are many developments problem in hovercraft in terms of usability due to the emergence of hovercraft designs. Therefore, in this study, we propose a hovercraft as a fire extinguisher on a ship in the middle of the sea. The hovercraft frame is created using 3D printing with dimensions of 37 cm long, 30 cm wide, and 17 cm high. The hovercraft design uses a smartphone application as a remote control, which is developed using MIT App Inventor and ESP32 as a microcontroller. This hovercraft is controlled at a distance without any obstacles at 42 meters and with wall obstacles at 12 meters. The addition of DC water pump components and nozzles are used as fire extinguishers and 2 (two) servos to regulate the direction of watering, and the furthest range of watering points is at 2 meters 10 cm. The power source usage of the battery time reaches 50 minutes with active hovercraft movement. The selection of low power consumption components and lightweight 3D print materials makes this hovercraft effective in working with only a 12-volt battery and can operate for almost 2 hours.

Abstract

This study aims to implement a real-time streaming system as a monitoring tool during the ship berthing process at a smart port, analyze the effectiveness of the streaming system in improving the monitoring and safety of the ship berthing process at a smart port, and explain how the components work in real-time to support the ship berthing process at a smart port. The ship berthing process is a crucial stage in port operations that requires real-time monitoring to ensure safety and efficiency. The developed system uses a Raspberry Pi as the main controller integrated with a V2 camera module, a proximity sensor, a WiFi hotspot module, and an Internet of Things (IoT)-based power monitoring system. Visual data in the form of streaming video and sensor data are sent in real-time to the monitoring application to assist port operators in monitoring the distance of ships to the dock. The research method used is Research and Development (R&D) which includes the design, assembly, testing, and evaluation stages of the system. Test results show that the system performs well in displaying real-time video streaming with an average streaming delay of 1.54%, accurately detecting vessel distances with an average of 0.81%, and providing relevant supporting information to improve the safety of ship berthing processes. Therefore, this system has the potential to be a supporting solution in the development of a safe and efficient smart port concept.

Abstract

Renewable energy sources are energy sources formed through continuous processes, making their availability abundant and inexhaustible. Examples of renewable energy sources include solar energy, biomass energy, wind energy, hydropower, geothermal energy, wave energy, and others. The purpose of this study is to evaluate the efficiency and the ideal design of a Vertical Axis Wind Turbine (VAWT) as a sustainable alternative energy source. In addition, energy storage technology through renewable energy–based battery charging systems has also become an important focus, such as battery charging systems using solar panels that can be adapted to wind turbines. With the increasing demand for energy and the negative consequences of fossil fuel usage, there is a growing interest in finding more environmentally friendly renewable energy sources. Tests conducted in two different regions showed varying results, which were influenced by the geographical location of each area. This turbine is designed using PETG (Polyethylene Terephthalate Glycol) material, which has high transparency and strong resistance to chemicals. Based on the test results, the experiment in Nganjuk generated 13.2 Wh of power, while in Surabaya it generated 9.9 Wh. The spiral design allows the turbine to capture wind from multiple directions and reduce wasted wind flow, thereby maximizing the turbine’s ability to rotate the generator rotor.

Abstract

This study aims to analyze the impact of clinker cargo damage on operational efficiency and to identify the effects of truck delays (waiting trucks) and crane malfunctions on the operational efficiency of the clinker loading process at PT Varia Usaha Bahari JIIPE Gresik. The study employs a quantitative approach using a survey method involving 60 respondents. Primary data were obtained through the distribution of questionnaires, while secondary data were obtained from Daily Reports/Time Sheets and Statements of Facts (SOF). Data analysis included validity tests, reliability tests, classical assumption tests, simple linear regression analysis, the coefficient of determination, t-tests, and descriptive analysis of operational data. The results indicate that Clinker Cargo Damage has a positive and significant effect on Operational Efficiency, with a regression coefficient of 0.742, a calculated t-value of 7.852, a significance level of < 0.001, and an R² of 0.515. This means that the Clinker Cargo Damage variable explains 51.5% of the variation in Operational Efficiency. Operational Efficiency (Y) = 5.547 + 0.742 Clinker Cargo Damage (X). Analysis of Daily Reports/Time Sheets and Statements of Facts (SOF) revealed that waiting trucks are the dominant factor reducing operational efficiency, resulting in a total time loss of 1.72 hours and an estimated delayed tonnage of approximately 769 metric tons, whereas crane disruptions only caused a time loss of 0.32–0.63 hours with an estimated delayed tonnage of 143–282 metric tons. These findings indicate that truck delays have a greater impact on operational efficiency than crane malfunctions.

Abstract

The electric motor of a ship’s sewage pump operates continuously and plays an important role in the ship’s sanitation system. Therefore, motor condition monitoring is required to prevent operational disruptions. Motor damage is generally preceded by increased vibration caused by imbalance, bearing wear, or improper installation. This study aims to design a real-time monitoring system for electric motor damage of a ship’s sewage pump using a piezoelectric sensor as a vibration detector. The research method used was an experimental method consisting of system design, static testing, dynamic testing, and data analysis. The system was designed using a Moswell MW 125 motor as a representation of the sewage pump motor, a piezoelectric sensor as the vibration detector, an ESP32 microcontroller as the data processor and transmitter, and Node-RED as the monitoring display platform. Dynamic testing was carried out for 30 minutes with data readings taken every 5 minutes. The test results showed that the monitoring system worked according to the design. The motor vibration value under normal conditions ranged from 0.2 to 0.5 mm/s during the testing period, which was categorized as safe and stable. The system was able to display vibration data in a real-time, continuous, and accurate manner through the dashboard. Therefore, the piezoelectric sensor-based monitoring system can be used as an early detection tool for motor damage and to support preventive maintenance of the ship’s sewage pump electric motor.

Abstract

Freon is one of the refrigerants used in refrigeration systems. The refrigeration system has a very important role, namely to preserve food ingredients so that food can last longer. The use of freon is not only used in ships but is widely found in home appliances in refrigeration systems used in freezers, air conditioners, refrigerators, and dispensers. If more freon is used, the negative impact that arises is greater, namely the depletion of the ozone layer and global warming which can have a bad influence on health, the life of living things and the environment. The purpose of this researcher is to create a tool to reduce the negative impact of freon use, namely by using peltier as a cooling medium with environmentally friendly thermoelectric modules. This study uses trial and error methods. Where the trial process is carried out by turning on one of the working push buttons and observing the temperature value. Then it is processed by the control system, namely Arduino Mega which will later provide a PWM output signal to the IRF540 mosfet when the output temperature value is in line with the reference value and vice versa. The test of this tool was carried out by comparing measurements between the author's prototype tool and the standard measuring tool, namely the digital thermometer. Based on the test results, this device can produce a minimum temperature of 140C at 30-minute intervals without any media. The trial using 330ml bottled water can reach a temperature of 170C within 30 minutes in the cooler box. This tool is also equipped with an automatic monitoring system using a PWM signal in the form of a change in fan speed, which is 255 RPS maximum speed and when getting a PWM signal it changes to 50 RPS. The percentage of errors resulting from the comparison of standard measuring instruments and sensor values had the highest and lowest percentages of 2.37% and 0.84% in cold dispersion conditions without charge. Then the highest and lowest error percentages were 1.69% and 0.72% in the state of containing a load of 1 330ml mineral bottle. This ptototype uses data recording using Micro-SD as a data logger.

Abstract

Technological developments and modern industrial needs increasingly demand high energy efficiency in refrigeration machine operations. In this context, the development of a more efficient cooling machine control system is very necessary. Portable cooler boxes using Thermoelectric Cooler (TEC) technology are an innovation to improve the quality and durability of fish caught by fishermen in Surabaya. This research aims to design and test a cooler box that can maintain low temperatures for a long time. This research method uses experimental methods, a series of tools and uses two test plans, namely: static and dynamic testing. The components used are three Peltier elements supported by a 12V 54A power supply, a 10K NTC temperature sensor, and a passive thermal regulator heatsink with fan. Precision testing data on the comparison sensor (thermodigital), obtained an average value of 3.75%. The error value is still categorized as a safe difference value and the tool works according to its function. Test data shows that the Cooler box can maintain a temperature between 5°C to 10°C, this temperature is ideal for slowing down the process of fish spoilage. Testing was carried out by integrating an Arduino Nano for real-time temperature monitoring which is displayed on the LCD and stored on a MicroSD. Test results show that this cooling system is effective in maintaining a stable temperature under various conditions of use, with an electrical energy consumption of 3111.38Wh per 6 hours.
