Ships contribute to CO2 gas emissions. The government's effort to reduce these emissions is by having Onshore Power Supply (OPS) facilities. OPS is a technology that allows ships at anchor to turn off their engines and connect to the local electricity network for electricity supply. Port of Berlian currently has 8 OPS spot managed by PT. Lamong Energi Indonesia. The use of OPS still needs to be examined using valid methods. In this research, researchers use the assessment methodology that has been used at the port of Lisbon regarding this onshore electricity facility type of port where the ship is docked (mooring vessel). In this methodology, the assessment process carried out includes data gathering and data processing processes. Apart from this process, it is necessary to review the character of the port or terminal that we will examine ships that most often use land-based electricity facilities are ships with a size of 1000-2999 GT. The use of land electricity facilities provides cost efficiency of 78%. This land electricity facility is used by General Cargo and Container type ships. These results indicate that the use of land electricity facilities is still inefficient ( 2.7%) and there is a need for further review of the implementation of existing policies.

The maritime industry, a cornerstone of global trade and commerce, relies heavily on effective communication, primarily through Maritime English. Ensuring safety, operational efficiency, and regulatory compliance on international waters necessitates proficiency in this standardized form of English. Despite its critical role, many maritime professionals struggle with Maritime English, especially speaking and critical thinking skills. This study explores how facilitated critical thinking in speaking can enhance Maritime English proficiency. Facilitated critical thinking involves instructional strategies that promote analysis, synthesis, and evaluation of information through interactive dialogues, problem-solving tasks, reflective practice, and collaborative learning. This study employs a mixed-methods approach, including quantitative and qualitative phases, to examine these strategies among maritime students and professionals. Results from paired samples statistics, correlations, and t-tests indicate significant improvements in speaking proficiency and critical thinking skills following the intervention. The findings suggest that integrating critical thinking into language instruction effectively addresses the unique challenges maritime professionals face, ultimately enhancing communication and safety in the maritime industry

This applied scientific work is entitled "Design of Automatic Smart Berthing System Based on Arduino". Ships are a comfortable alternative transportation. Currently, ship development is needed so that they can operate properly. During the docking process, ship accidents often occur in ports both nationally and internationally. Therefore, a better development or safety is needed that can be given to ships during the docking process. This tool uses the Arduino Nano microcontroller as the main control and an ultrasonic sensor as a distance counter to prevent accidents. This applied scientific work aims to realize and facilitate work on the ship by abandoning manual methods. Berthing is the location of the ship's mooring or security, the area around the ship where the anchor is thrown, the ship's residence, employing the ship's crew and positioning the ship in the desired place. This scientific paper uses experimental research as its research method. The use of experimental research methods in educational research will be faced with problems concerning research subjects. Experimental research is also research that is carried out intentionally by researchers by providing certain treatments to research subjects in order to create a tool or design that is expected by the researcher.

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.

Kualitas udara pada area terbatas (restricted area) di atas kapal, khususnya ruang merokok (smoking area), berpotensi menimbulkan risiko kesehatan akibat paparan akumulasi asap rokok dan gas berbahaya seperti karbon monoksida (CO). Sistem ventilasi konvensional saat ini dinilai belum optimal dalam menyeimbangkan sirkulasi udara dengan fluktuasi jumlah pengguna di dalam ruangan tersebut. Oleh karena itu, penelitian ini bertujuan untuk merancang sistem pemantauan kapasitas ruang dan kontrol sirkulasi udara berbasis Internet of Things (IoT) guna meningkatkan kualitas udara serta kenyamanan pengguna. Metodologi penelitian mencakup perancangan sistem, pembuatan purwarupa (prototype), dan pengujian kinerja perangkat keras yang mengintegrasikan mikrokontroler ESP32, sensor gas MQ-2, sensor inframerah, pemurni udara (air purifier), serta sistem blower. Hasil pengujian menunjukkan bahwa purwarupa sistem secara efektif mampu mendeteksi keberadaan asap rokok, mengaktifkan sirkulasi udara secara otomatis, serta menghitung dan membatasi jumlah pengguna secara real-time melalui antarmuka aplikasi IoT. Implementasi sistem cerdas ini diharapkan dapat mengoptimalkan pengelolaan area terbatas, mereduksi polusi udara dalam ruang, serta mendukung pemenuhan standar keselamatan dan kesehatan kerja di lingkungan maritim. Air quality in restricted areas on board ships, particularly smoking areas, poses potential health risks due to the accumulation of cigarette smoke and hazardous gases such as carbon monoxide (CO). Current conventional ventilation systems are considered suboptimal in balancing air circulation with the fluctuating number of occupants in the room. Therefore, this study aims to design an Internet of Things (IoT)-based capacity monitoring and air circulation control system to improve air quality and user comfort. The research methodology encompasses system design, prototype fabrication, and performance testing of hardware integrating an ESP32 microcontroller, an MQ-2 gas sensor, infrared sensors, an air purifier, and a blower system. The testing results demonstrate that the prototype system effectively detects cigarette smoke, automates air circulation, and tracks as well as limits the number of users in real-time through an IoT application interface. The implementation of this smart system is expected to optimize the management of restricted areas, reduce indoor air pollution, and support occupational health and safety standards in the maritime environment.

Throughout maritime history, ships have played a strategic role in international trade routes. Therefore, the proper use of English in ship guidance and navigation is crucial to avoid danger. This study measures the effectiveness of English-language emergency communication among shipping professionals by surveying 285 respondents. The research instrument was a questionnaire with 10 questions on a five-point Likert scale. Descriptive analysis results showed an average score of 4.66 out of 5.00, indicating fairly high communication effectiveness. However, there were variations in scores, suggesting that some sailors still need additional training. These findings underscore the importance of strengthening the maritime training curriculum based on Standard Marine Communication Phrases (SMCP).
