Abstract

Air motor starter is a component that functions to rotate the engine auxiliary flywheel to move the piston for the first combustion to occur. In this system, high-pressure air from a compressor or air tank is used to drive a starter motor that is directly connected to the engine crankshaft. As the starter motor operates, pressurized air is channeled into the starter motor cylinders, creating a rotational movement on the shaft that eventually rotates the auxiliary engine crankshaft. Air motor starters on MT Green Stars are essential for the auxiliary engine starting system on board MT Green Stars. This study aims to analyze the factors that cause the failure of auxiliary engine start failure caused by the rupture of the starter motor water bearing and the impact on the auxiliary engine. This research uses a descriptive analysis method using HAZOP data analysis techniques and data collection from observations, logbooks, journals, manual books, and interviews The research was conducted on the MT Green Stars ship which has three auxiliary engines and is experiencing problems with the starting system. Based on the research, failure factors in auxiliary engines are caused by several factors, namely starter motor water, injectors, starter motor water, and fuel filters. The impact of auxiliary engine start failure causes failure of the electrical system, system, pump, hydraulic and pneumatic system disorders, work efficiency disorders, risk of damage to the main engine, and safety and regulatory disorders. To handle it, maintenance needs to be carried out, both preventive maintenance and breakdown maintenance. The suggestions that researchers make are to routinely carry out maintenance according to PMS (Planned Maintenance System), carry out toolbox meetings, check especially auxiliary engines.

Abstract

Background: The Teaching Factory (TEFA) method has emerged as a practical approach in ESP Maritime English, particularly in enhancing cadets’ participation in simulated maritime scenarios such as loading and unloading communication, onboard communication checking, and goods tracking via phone. Grounded in experiential learning theory, TEFA bridges the gap between theoretical knowledge and real-world application, preparing cadets for industry demands.Methodology: This study used qualitative case study approach to explore seventh-year maritime cadets’ perceptions of the TEFA method. The subjects were seventh semester maritime cadets from maritime academy. Data collection involved classroom observations and semi-structured interviews, focusing on the cadets’ engagement, confidence, and learning outcomes.Findings: The results showed that 65% of cadets agreed that TEFA made learning Maritime English easier, while 60% found the method enjoyable and engaging. Additionally, 55% of cadets reported reduced anxiety, attributing their increased confidence to the hands-on learning experience provided by TEFA simulations. However, 15% of cadets remained neutral, expressing the need for more structured guidance and additional practice to adapt to the interactive learning approach fully.Conclusion: This study concludes that TEFA effectively bridges the gap between theoretical knowledge and practical maritime communication, making learning more industry relevant. Future research should examine blended learning methods, digital feedback systems, and long-term evaluations to strengthen TEFA’s role in improving cadets’ communication skills and preparedness for maritime operations. Integrating online and practical training can enhance learning flexibility while reinforcing real-world application through virtual simulations. Digital feedback tools can help cadets refining pronunciation and fluency by providing immediate assessments and personalized guidance.Originality: This study addresses a gap in understanding how TEFA influences cadets’ perceptions and learning outcomes in ESP Maritime English, particularly in simulated maritime scenarios. It provides insights into the method’s effectiveness and areas for improvement, offering a foundation for future innovations in maritime education.

Abstract

Penelitian ini bertujuan menganalisis kinerja angkutan peti kemas dari PT  Terminal Peti Kemas Surabaya (TPS) menuju kawasan industri di wilayah Surabaya dan sekitarnya. Pelabuhan sebagai simpul utama dalam sistem logistik memiliki peran strategis dalam menjamin kelancaran distribusi barang dari dan ke wilayah hinterland. Namun, pada praktiknya, proses pengangkutan peti kemas dari terminal menuju kawasan industri masih menghadapi berbagai kendala yang berpotensi memengaruhi efisiensi dan ketepatan waktu pengiriman. Metode penelitian yang digunakan adalah pendekatan kualitatif dengan teknik pengumpulan data melalui observasi lapangan, wawancara, dan dokumentasi. Analisis data dilakukan melalui tahapan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa secara internal TPS telah memiliki fasilitas, peralatan, serta sistem operasional yang memadai dan terstruktur. Proses pengeluaran peti kemas dari lapangan penumpukan hingga gate terminal telah berjalan sesuai prosedur operasional standar. Namun, kinerja tersebut belum sepenuhnya optimal dalam mendukung ketepatan waktu distribusi ke kawasan industri. Hambatan utama berasal dari faktor eksternal berupa kepadatan lalu lintas, keterbatasan kapasitas infrastruktur jalan, serta tingginya volume kendaraan di sekitar area pelabuhan dan kawasan industri. Kondisi ini menyebabkan terjadinya antrean kendaraan dan ketidakstabilan waktu tempuh pengiriman. Dengan demikian, peningkatan kinerja angkutan peti kemas memerlukan penguatan koordinasi antar pemangku kepentingan serta integrasi yang lebih baik antara pengelolaan terminal dan sistem transportasi darat guna mendukung kelancaran rantai pasok industri.

Abstract

Information regarding water depth and seabed morphology is essential in hydrographic surveys to support navigational safety, the monitoring of shipping channels, and the management of water bodies. This study aimed to develop a depth mapping system by integrating a Deeper Pro+ sonar, the Fish Finder application, and an Unmanned Surface Vehicle (USV) as the sensor-carrying platform. The research employed the Research and Development (R&D) method using the ADDIE model. Testing was conducted in the swimming pool and training pool at the Surabaya Merchant Marine Polytechnic, utilizing both radial and parallel sounding patterns. Each combination of location and pattern yielded 30 measurement points. Results from the swimming pool tests revealed three dominant depth zones: approximately 1.0 m, 2.0 m, and 4.5 m. In the training pool, the radial pattern yielded depths ranging from 1.7 m to 6.5 m (average 4.64 m), while the parallel pattern yielded depths ranging from 1.4 m to 6.5 m (average 4.62 m). The radial pattern highlighted depth variations toward the central area, whereas the parallel pattern provided a more uniform data distribution. The integration of the sensor, positioning system, mapping application, and USV successfully generated depth data and bathymetric visualizations in relatively calm waters.

Abstract

Occupational Safety and Health (OSH) management in Liquified Natural Gas (LNG) terminals requires stringent alignment with both general workplace safety and process safety protocols. This study evaluates the implementation of the OSH Management System (SMK3) at PT X, an LNG logistics terminal in Indonesia, focusing on employee Personal Protective Equipment (PPE) compliance and visitor safety controls. Utilizing a qualitative case study design, data were collected through field observations, document reviews, and semi-structured interviews with nine key informants across operational and safety divisions. The data were analyzed using a formal SWOT/TOWS matrix to develop strategic interventions. The findings indicate that while PT X’s institutional procedures—such as mandatory safety inductions, daily toolbox meetings, and medical fit-to-work screenings—are consistent with ISO 45001 standards, critical field execution gaps remain. Empirical evidence highlights recurring PPE non-compliance driven by human factors (e.g., thermal discomfort), visitor violations of electronic device restrictions in hazardous explosive zones, and logistical bottlenecks due to insufficient visitor PPE inventory during peak periods. The study concludes that achieving optimal safety compliance requires moving beyond bureaucratic procedures. Practical implications include the necessity for risk-based PPE procurement, the enforcement of a controlled intrinsically-safe device management policy, and enhanced human-centric safety supervision.

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

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

The aim of this study is to design a battery charging system using solar panels, integrated with an IoT-based monitoring system to improve efficiency and ease of supervision. The system utilizes the photovoltaic effect to convert solar energy into electrical energy, which is then stored in a battery through the regulation of a solar charge controller. The main components in this design include a solar panel, lead-acid battery, ESP32 microcontroller, current and voltage sensors, and the Blynk application for remote monitoring. The research method involves several stages, including the design of hardware such as solar panels, current and voltage sensors, and a step-down regulator, as well as software development using the Blynk platform and ESP32 programming. Test results show that the system is capable of achieving charging efficiencies between 89.45% and 99.57%, with optimal performance under clear weather and maximum sunlight conditions. The IoT system performs well up to a distance of 10–15 meters, with an average data transmission delay of less than 1.5 seconds. Therefore, this device proves to be effective as an independent battery charging and energy monitoring solution in locations without permanent electricity access.

Abstract

From this research, monitoring can be carried out using the XH-M203 water level which can run a wireless sensor to measure the water in the tank and then the results of these measurements will give a command to the pump to fill the tank. This tool is made to automatically control the height and automatically fill the tank. The design of this tool is based on the fact that some ships still use a manual system in the form of a float gauge to monitor water levels, so by designing this tool the monitoring and control process will be easier. System testing shows that the system is able to control water levels with high accuracy and is responsive to changes in water levels. The results of this research are that the XH-M203 water level is able to detect height and automatically control the simulated tank. The results of the detection are processed through a controller and LED as a marker for high and low levels so that all parties can know the water level in the tank. Then automatic control uses a pump which will fill automatically so that the tank capacity can be controlled through this tool. With 6 trials of 90% capacity in calm water there was an error of 0.01% and 90% capacity with the tank shaking there was an error of 0.01%. The next test with a tank capacity of 60% in still water conditions has an error of 0% and a capacity of 60% there is vibration there is a 0% error, and testing with a tank capacity of 30% in still water conditions there is an error of 0% and at 30% capacity there is vibration in the tank there is an error of 0 %. So this tool can work with an accuracy of 99.98% and a tool error of 0.02%.

Abstract

Water is the most abundant thing on earth. However, in reality, the water on ships is not always considered consumable. This is caused by the FWG (Fresh Water Generator) auxiliary machine processing process. FWG is a ship auxiliary engine that produces fresh or salt water through a distillation process. FWG carries out distillation using a heat source from the jacket for the evaporation process to produce fresh water. The accuracy of the salt content produced through FWG is not yet known. If processed FWG products whose salt content is unknown are still consumed, it will have a negative impact on health, such as: kidney failure and the risk of developing kidney stones. Based on this problem, a tool was designed to monitor the salt content of processed FWG on board ships so that it could be used by all crew members and passengers. According to quality standards, the salt content that can be consumed by humans is below 50 ppm, with a pH between 5.0 to 7.5 and a turbidity of between 5 and 25 NTU. By designing this tool, we will be able to monitor the suitability of FWG fresh water so that it can be consumed on board. With the help of LCD, it will be able to help provide information regarding monitoring results of water quality. In testing this tool, the pH sensor, turbidity sensor and salinometer conductivity sensor will help to test the suitability of fresh water.
