Abstract

A reliable data communication network is essential in supporting Vessel Traffic Service (VTS) operations, especially in managing vessel traffic in the Class I Navigation District of Tanjung Perak, Surabaya. However, challenges such as network reliability, bandwidth capacity, and potential interference are still obstacles in ensuring efficient operations. This research aims to analyze the condition of the data communication network at the Tanjung Perak Class I Navigation District VTS, focusing on the technology used, its performance, and the obstacles faced. This research uses a qualitative descriptive approach, with data collected through direct observation, interviews with VTS operators, and analysis of related documents. The results show that the communication network at VTS uses Very High Frequency (VHF) frequency-based radio communication technology to support operations, such as digital maps of ship traffic and Automatic Identification System (AIS) systems. In conclusion, the data communication network at the Tanjung Perak Class I Navigation District VTS has met basic operational needs, but still requires further development in terms of technology and infrastructure to improve its efficiency and reliability. This research provides recommendations for the integration of advanced technology, infrastructure improvement, and human resource training to optimize the performance of the communication network.

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

Approximately 2.89% of the world’s carbon footprint can be attributed to the shipping sector. To mitigate this impact, the International Maritime Organization (IMO) established the MARPOL Annex VI regulations, which impose stringent limits on sulfur oxides (SO_x), nitrogen oxides (NO_x), and carbon dioxide (CO_2) emissions. As an archipelagic nation, Indonesia faces unique strategic and operational challenges in achieving regulatory compliance. This study evaluates the implementation of MARPOL Annex VI at Tanjung Perak Port, Surabaya, utilizing a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis framework. A mixed-methods approach was employed, integrating qualitative insights with quantitative data derived from stakeholder questionnaires. The analysis identifies key internal and external factors influencing the adoption of green shipping practices. Findings indicate that Indonesia’s transition requires a tripartite strategy: robust regulatory frameworks, technological innovation, and human capital development. Key recommendations include strengthening the enforcement of monitoring systems—specifically Measurement, Reporting, and Verification (MRV)—and introducing economic instruments such as an Emissions Trading System (ETS). Furthermore, the adoption of energy-efficient technologies and alternative marine fuels is critical. This research aligns with Sustainable Development Goals (SDGs) 7, 9, 13, and 14, providing a roadmap to enhance the maritime industry's competitiveness while contributing to global decarbonization targets.

Abstract

Penelitian ini bertujuan untuk menganalisis faktor penyebab dan dampak dari tersumbatnya nozzle burner pada auxiliary steam boiler di kapal MV. Pan Kristine. Permasalahan yang muncul berupa penurunan tekanan uap dan flame failure saat kapal berlabuh, yang diduga disebabkan oleh gangguan pada sistem pembakaran. Data dikumpulkan melalui observasi langsung, wawancara dengan kru mesin, dokumentasi, serta studi pustaka. Hasil penelitian menunjukkan bahwa penyumbatan nozzle burner disebabkan oleh kurangnya perawatan rutin sesuai Planned Maintenance System (PMS), sistem filtrasi bahan bakar yang tidak efisien, nozzle yang aus atau rusak, serta jarak elektroda yang tidak sesuai dengan manual book. Dampak dari kondisi ini meliputi penurunan efisiensi pembakaran, peningkatan akumulasi jelaga dan kerak di ruang bakar, serta gangguan operasi boiler secara keseluruhan. Penelitian ini merekomendasikan penerapan PMS yang ketat, pemeriksaan berkala pada filter dan nozzle, serta pelatihan kru untuk meningkatkan pemahaman terhadap sistem pembakaran guna menjamin keandalan dan efisiensi kerja auxiliary boiler.   This study aims to analyze the causes and impacts of nozzle burner clogging in the auxiliary steam boiler aboard the MV. Pan Kristine. The issue arose from steam pressure drops and repeated flame failures while the ship was anchored, suspected to result from malfunction in the combustion system. Data were collected through direct observation, interviews with engine crew, documentation, and literature study. The findings reveal that the clogging of the nozzle burner is caused by insufficient routine maintenance according to the Planned Maintenance System (PMS), inefficient fuel filtration, worn or damaged nozzles, and electrode spacing that does not comply with the instruction manual. These issues lead to reduced combustion efficiency, increased soot and scale accumulation in the combustion chamber, and overall operational disruption of the boiler. The study recommends implementing a strict PMS, regular inspection of fuel filters and nozzles, and improved crew training to ensure the reliability and efficiency of the auxiliary boiler system.

Abstract

Boilers experience frequent problems, such as scale formation, unstable steam pressure, incomplete combustion, and difficulty starting. Therefore, this study uses a quantitative method with the Failure Mode and Effect Analysis (FMEA) approach, which aims to determine maintenance and prevention to minimize these problems. This method determines the failure priority obtained from the Risk Priority Number (RPN) calculation based on assessment factors such as severity, frequency of occurrence, and the likelihood of failure being detected in each component. The results of these calculations indicate that the steam drum component falls into the highest category, with an RPN of 32. The other 12 components fall into the medium category: the feed water pump, electrode, photocell, nozzle, blower fan, solenoid valve, fuel pump, blowdown valve, main steam valve, scum valve, non-return valve, and gauge glass, with RPN values ranging from 12 to 24. Furthermore, the components in lowest category include the fuel filter, safety valve, and manometer, with RPN values ranging from 8 to 10. Therefore, the recommended improvements based on the FMEA results can be used as evaluation material to ensure the effectiveness of the improvements. Furthermore, regular boiler maintenance and monitoring are required, especially for components such as the steam drum, which requires additional routine maintenance schedules, repeated evaluations related to water treatment, and determining appropriate repairs for any steam drum failures.
