Abstract

An electric motor is an electrical machine device that uses electromagnetic principles to convert electrical energy into mechanical energy. This mechanical energy is used as a driving force in the auxiliary mecchinery on board. There are many causes of damage to electric motors and the impact on the operating system can be disrupted. Some of the causes of damage to electric motors are heat, dirt, humidity, vibration and electricity quality. Other causes are usually poor maintenance and less than optimal cleaning. The aim of this research is to find out the causes of damage to electric motors on ships and to find out how to prevent damage to electric motors. Data collection methods used field methods, literature and interviews using descriptive qualitative data analysis techniques and obtained results on factors that caused damage to electric motors on MT ships. Transko Arafura, Factors that cause damage to electric motors on MT ships. Transko Arafura, namely vibrations in the electric motor due to damage to the worn ball bearing and shaft so that the shaft is not balanced. Prevents damage to the electric motor on the MT ship. Transko Arafura is by replacing the ball bearing with a new one and refacing the shaft by turning. ABSTRAK Motor listrik merupakan perangkat mesin lisrik yang menggunakan prinsip elektromagnetik yang mengubah enegi listrik menjadi energi mekanik. Energi mekanik tersebut dimanfaatkan sebagai tenaga penggerak pada permesinan bantu di atas kapal. Kerusakan motor listrik banyak penyebabnya dan dampaknya sistem operasi dapat terganggu. Beberapa penyebab kerusakan motor listrik adalah panas, kotor, lembab, vibrasi dan kualitas listrik. Penyebab lain biasanya faktor pemeliharaan yang kurang baik dan pembersihan kurang maksimal. Tujuan penelitian ini yaitu dapat mengetahui penyebab kerusakan pada motor listrik di kapal dan dapat mengetahui cara mencegah terjadinya kerusakan pada motor listrik. Metode pengumpulan data dengan metode observasi, wawancara dan dokumentasi dengan teknik analisis data kualitatif deskriptif dan diperoleh hasil faktor yang menyebabkan kerusakan pada motor listrik di atas kapal MT. Transko Arafura yaitu adanya getaran pada motor listrik karena kerusakan pada ball bearing dan shaft yang aus sehingga shaft tidak balance, mencegah terjadinya kerusakan pada motor listrik di atas kapal MT. Transko Arafura yaitu dengan mengganti ball bearing dengan yang baru dan refacer pada shaft dengan pembubutan.

Abstract

This research examines the significant role of technology in education at Barombong Maritime Polytechnic, particularly in teaching Maritime English. Using a mixed-methods approach that combines qualitative and quantitative analysis, the research examines how technology affects the effectiveness and engagement in Maritime English learning. The findings underscore the crucial role of technology at various stages of learning, from preparation to evaluation. The use of technology, including compiling e-books, leveraging YouTube for content delivery, and utilizing the Marlin Test app, demonstrates a wide range of applications in enhancing learning outcomes. Throughout the learning process, the frequent utilization of technology-based tools and platforms fosters an interactive and supportive learning environment conducive to effective learning. From computers and projectors to applications such as Wordwall and Zoom Meeting, technology enriches the educational experience, provides access to a variety of resources, and facilitates collaboration between students and educators. Additionally, technology-supported evaluation methods, such as Google Forms for theory exams and video recording for speaking assessments, offer a more efficient and comprehensive approach to assessing student progress and proficiency.

Abstract

Maritime English-speaking proficiency is a critical competency for seafarers to ensure safe and effective international maritime communication. However, speaking performance among vocational maritime cadets in Indonesia routinely falls below required global standards. This qualitative descriptive study, employing a narrative inquiry approach, investigated the specific English-speaking difficulties and underlying influencing factors among twenty purposively selected fourth-semester Marine Engineering cadets at Barombong Merchant Marine Polytechnic. Data collected via in-depth interviews and non-participant classroom observations were systematically analyzed utilizing the Miles and Huberman framework. The findings reveal that cadets confront severe linguistic barriers (restricted vocabulary, pronunciation errors, and grammatical deficiencies) alongside profound psychological hurdles (debilitating anxiety, low self-confidence, and fear of making mistakes). Furthermore, these difficulties are compounded by an interplay of internal and external factors, including socio-economic backgrounds, conventional instructor pedagogy, substandard language facilities, senior peer pressure, and exhaustive physical training schedules. Collectively, these multi-dimensional constraints severely impede communicative competence. This study underscores the urgent need for targeted pedagogical interventions, curriculum alignment, and institutional policy reforms to enhance Maritime English proficiency and ensure global maritime workforce readiness.
