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

Effective use of Maritime English is essential for maintaining navigational safety and preventing communication failures in international waters, particularly within Vessel Traffic Service environments where real time decisions influence vessel movements and risk levels. Despite the global adoption of Standard Marine Communication Phrases as a safety protocol, there remains limited empirical evidence on how these phrases are enacted in authentic operational settings and how such practices inform the teaching of Maritime English. This study investigates the real-world application of Maritime English for safety communication at Benoa Vessel Traffic Service in Indonesia. Using a qualitative descriptive design, data were generated through analysis of five communication transcripts, eleven semi structured interviews with operators, and three days of field observations. Findings reveal selective adherence to standard phrases during routine procedures, frequent shifts to simplified English and code switching in complex multilingual situations, and pragmatic prioritization of clarity and time sensitive coordination over strict protocol. These patterns highlight gaps between prescribed language taught in training and communicative realities faced by operators. The study contributes empirical insight for refining Maritime English pedagogy by integrating authentic communication tasks, simulation of multilingual scenarios, and training for adaptive yet safety-oriented language practices. In a broader context, the findings reinforce the importance of aligning ESP curriculum design with real operational discourse to support global maritime safety and enhance English language preparedness among future maritime professionals.
