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.
