Abstract

The maritime transportation sector, especially in archipelagic countries like Indonesia, faces significant challenges in optimising ship speed and fuel efficiency, particularly when using hybrid propulsion systems. This study aims to design a ship speed control system based on fuzzy logic integrated with a hybrid propulsion system (BLDC motor and diesel engine) for a trimaran vessel. The research employed both static and dynamic testing on the system, measuring parameters such as motor RPM, current consumption, voltage, and fuel efficiency across different speed modes (from 4 km/h to 11 km/h). The results showed that the fuzzy logic-based control system notably improved speed stability and fuel efficiency, especially at lower speeds, compared to conventional systems. Additionally, the system effectively adapted to environmental conditions such as waves and currents, optimising power distribution between the BLDC motor and diesel engine. The conclusion emphasises that this fuzzy logic-based control system offers a promising solution to enhance operational efficiency in hybrid propulsion systems for maritime vessels, ensuring reduced fuel consumption and improved environmental sustainability.

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

Pengelolaan air ballast yang tidak optimal berpotensi menimbulkan pencemaran lingkungan laut akibat perpindahan organisme antar perairan. Oleh karena itu, penerapan Ballast Water Management Plan (BWMP) menjadi hal yang penting dalam mendukung kepatuhan terhadap ketentuan Ballast Water Management Convention (BWMC). Penelitian sebelumnya menunjukkan bahwa gangguan pada sistem Ballast Water Treatment System (BWTS), khususnya pada komponen pengolahan kimia dapat memengaruhi efektivitas pengelolaan air ballast. Pada penelitian ini memiliki keterbaruan pada foku s kajian optimalisasi penerapan BWMP melalui identifikasi akar permasalahan malfungsi sistem Total Residual Oxidant (TRO) akibat sumbatan pada T-strainer serta keterkaitannya dengan aspek operasional dan perawatan di atas kapal. Metode penelitian yang digunakan adalah metode kualitatif deskriptif dengan teknik pengumpulan data melalui observasi, wawancara, dan dokumentasi. Analisis data dilakukan menggunakan diagram fishbone. Hasil penelitian menunjukkan bahwa tidak optimalnya penerapan BWMP dipengaruhi oleh faktor manusia, mesin, metode, material, lingkungan, dan manajemen operasional. Sumbatan pada T-strainer sistem TRO akibat endapan yang tidak dibersihkan secara rutin menyebabkan kinerja sistem BWTS menjadi tidak stabil dan memicu alarm maupun kondisi trip. Selain itu, keterbatasan pemahaman kru terhadap pelaksanaan ballast operation turut memengaruhi efektivitas pengelolaan air ballast. Dengan peningkatan perawatan sistem secara berkala dan penguatan pemahaman awak kapal, penerapan BWMP dapat berjalan lebih optimal dan mendukung upaya pencegahan pencemaran air laut.

Abstract

Energy efficiency in water heaters is a crucial factor in ship operational environments due to limited electricity resources that rely on generators. This study aims to design and build an IoT-based water heater monitoring system with an innovative heat storage medium in the form of a mixture of silica sand and paraffin wax to improve thermal efficiency. Although previous studies have developed temperature monitoring and control systems in IoT-based water heaters, this study specifically fills this gap by analyzing the performance of adding silica sand to overcome the low thermal conductivity of paraffin wax. Using the Research and Development (R&D) method, this system was built with an ESP32 microcontroller as the control center, a DS18B20 temperature sensor for accurate measurements, and the Blynk and Google Sheets platforms for real-time monitoring and data recording. Performance testing was conducted by comparing the water heating rate between pure paraffin wax media and the mixed media. The results showed that the monitoring system functioned reliably, and the main finding proved that the addition of silica sand to paraffin wax significantly increased heating efficiency. This was clearly seen from the reduction in time required to raise the water temperature to 40°C, from 2.5 hours to only 1 hour in the second heating cycle. The results of this study indicate that the integration of silica sand and paraffin wax media with IoT technology can increase the efficiency of water heaters and provide an innovative solution for energy-efficient and environmentally friendly temperature control.

Abstract

Unmanned Surface Vehicle (USV) or unmanned ship has become a major focus in the development of shipping technology to improve the efficiency and safety of navigation on the water. This research carried out the design and creation of an unmanned ship system equipped with an ESP32 camera to detect the navigation lights of other ships and avoid potential collisions. In this system, the initial response of the ESP32CAM camera reads the color of the lights approaching the unmanned ship with less than 100 cm. ESP32CAM reads and identifies colors through image processing. When ESP32CAM detects green and red-light colors, the ESP32CAM microcontroller commands the buzzer to sound. The color detection system works with this command, if ESP32CAM detects red then the ESP32CAM microcontroller will send a signal to the servo motor to move left, while ESP32CAM detects green the ESP32CAM microcontroller will send a signal to the servo motor to move right. The servo motor functions as a ship rudder drive of a USV or unmanned ship. The Navigation lamp system test using ESP32CAM camera to prevent ship collisions is carried out with a predetermined scenario, independent light color testing, and whole system testing. The results of the research are : Color detection is successful. The camera can recognize the color of the light and the unmanned ship is able to take appropriate action to avoid collisions based on the color light signal and the navigation lamp system. The ESP32CAM camera can identify the optimum light at 100cm.

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

Penggunaan energi terbarukan merupakan solusi dalam mendukung pengembangan pelabuhan pintar (smart port), khususnya dalam pemenuhan sumber daya listrik yang stabil, berkelanjutan, dan efisien. Kebutuhan sistem energi alternatif menjadi relevan terutama akibat keterbatasan pasokan listrik berbasis bahan bakar fosil serta tuntutan efisiensi proses sandar kapal. Dalam konteks tersebut, pemanfaatan pembangkit listrik tenaga angin dan surya berpotensi meningkatkan kemandirian energi di lingkungan pelabuhan. Dalam penelitian sebelumnya, peneliti belum mengintegrasikan sistem hybrid dengan pemantauan real-time, pengolahan data, penggunaan mikrokomputer, dan konteks pelabuhan pintar. Beberapa penelitian hanya berfokus pada salah satu sumber energi. Keterbatasan tersebut mendorong penelitian ini untuk merancang sistem hibrida panel surya dan turbin angin vertikal yang dapat melakukan monitoring daya yang masuk , switching energi dan pemrosesan data secara real-time. Metode penelitian yang digunakan adalah Research and Development (R&D) yang meliputi tahap perancangan, perakitan, pengujian, dan evaluasi sistem. Hasil pengujian 1x24 jam membuktikan sistem mampu menghasilkan total energi ±68,16 Wh (±5,24 Ah), memenuhi ±72% kapasitas baterai 12 V. Panel surya mendominasi suplai sebesar 61% dengan daya rata-rata ±5,28 W pada siang hari. Turbin angin berkontribusi sebesar 39% dengan rata-rata daya ±0,72 W sebagai sumber pendukung di malam hari. Sensor cahaya BH1750 dengan ambang batas 50 lux berhasil menjadi pemicu switching otomatis antara siang dan malam. Modul MPPT juga berhasil menstabilkan tegangan output dari kedua sumber hingga mencapai titik daya maksimum. Secara keseluruhan, sistem beroperasi sesuai dengan tujuannya.

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.
