Abstract

Sistem pendingin mesin induk merupakan salah satu sistem penting di atas kapal yang berfungsi menjaga temperatur kerja mesin agar tetap stabil selama operasional kapal berlangsung. Salah satu komponen utama dalam sistem pendingin tersebut adalah strainer sea chest yang berfungsi menyaring lumpur, pasir, kerang, dan sampah laut sebelum air laut masuk ke pompa pendingin dan sistem pendingin mesin induk. Penelitian ini bertujuan untuk mengetahui pengaruh kondisi strainer sea chest terhadap kinerja pompa pendingin mesin induk serta upaya optimalisasi sistem pendingin di atas kapal. Penelitian menggunakan metode kualitatif dengan pendekatan deskriptif melalui observasi, wawancara, dokumentasi, dan studi kepustakaan selama pelaksanaan praktik laut (prala). Hasil penelitian menunjukkan bahwa penyumbatan strainer sea chest akibat lumpur, pasir, kerang, dan sampah laut menyebabkan aliran air pendingin terganggu, tekanan pompa pendingin menurun, dan temperatur mesin induk meningkat sehingga berpotensi menyebabkan overheating pada mesin induk. Selain itu, kurang optimalnya pemeriksaan dan pembersihan strainer sea chest secara rutin turut memengaruhi kinerja sistem pendingin mesin. Upaya yang dilakukan untuk mengoptimalkan sistem pendingin yaitu melalui pemeriksaan dan pembersihan strainer sea chest secara berkala, pemantauan tekanan pompa dan temperatur mesin induk, serta peningkatan disiplin kru mesin dalam pelaksanaan perawatan sistem pendingin kapal. Dengan perawatan yang baik, sistem pendingin mesin induk diharapkan dapat bekerja secara optimal sehingga risiko kerusakan mesin dan gangguan operasional kapal dapat diminimalisir.

Abstract

The development of simulation technology has become a crucial element in modern maritime education. This study aims to examine the effect of training simulator and the availability of bridge simulator equipment on the competence of Nautical cadets at Sorong Merchant Marine Polytechnic prior to sea practice. A quantitative approach with multiple linear regression was used to analyze the relationship between the independent variables (training simulator and bridge simulator) and the dependent variable (cadet competence). Data were collected from 26 cadets through structured questionnaires using purposive sampling. The results indicate that both variables significantly affect cadet competence, with the bridge simulator having a more dominant impact. The regression model yielded a high coefficient of determination (R² = 0.998), meaning that 99.8% of the variance in cadet competence is explained by the two predictors. These findings reinforce the critical role of simulation-based training, especially bridge simulators, in developing technical skills, navigation ability, situational awareness, and decision-making. The study supports the IMO-STCW framework, which mandates simulation in maritime certification. As a result, maritime education institutions are recommended to strengthen investment in training and bridge simulator facilities and integrate simulation-based methods into the curriculum to improve graduate competence and global competitiveness.

Abstract

Background: The Fresh Water Generator (FWG) is a critical shipboard system that produces potable and technical fresh water from seawater via vacuum evaporation, utilizing waste heat from the main engine jacket cooling water circuit.  The FWG is susceptible to operational disruptions including heat exchanger fouling, mineral scaling, vacuum system failures, thermal efficiency reduction, and salinity monitoring errors. Objective: This study investigates these operational challenges and the maintenance strategies employed to address them, based on the direct professional experience of marine engineers employed by Anthony Veder Rederijzaken, a Rotterdam-based LNG shipping company. Methods: A qualitative case study methodology was adopted, using semi-structured interviews with five marine engineers at the rank of Second and Third Engineer. Five respondents were sufficient because thematic data saturation was reached, with no new themes emerging from the final interviews. Interview data were analyzed manually through thematic analysis, supported by technical document review and structured literature comparison. Results: Five operational challenge themes were identified: biofouling and physical fouling of plate heat exchangers; mineral scaling from calcium carbonate and magnesium hydroxide precipitation; vacuum system degradation from air ingress; reduced thermal efficiency under variable engine load; and salinity monitoring system failures. Corresponding maintenance strategies include scheduled chemical descaling, vacuum integrity checks, routine performance monitoring, pump and ejector overhauls, and weekly salinometer calibration. These findings contribute a practitioner-grounded, route-adaptive framework for condition-based maintenance practice. Conclusion:  The findings offer evidence-based recommendations that advance maintenance management in maritime engineering and provide empirical material for strengthening maritime education curricula.

Abstract

This study aims to analyze the level of readiness, obstacles, and adaptability of cadets of the Sorong Shipping Polytechnic Ship Ship Study Program while carrying out tasks in the engine room. The research uses a quantitative approach with a descriptive design. Data was collected through a questionnaire containing 24 statements that included three constructs, namely readiness before sea practice, obstacles during practice, and occupational adaptation and safety. A total of 16 cadets who have carried out sea practice were selected using purposive sampling techniques. The data were analyzed using descriptive statistics with the help of IBM SPSS Statistics 22. The results of the instrument test showed that all items were valid with Cronbach's Alpha values of 0.966 each; 0,926; and 0.988, which indicates very high reliability. The results of the study showed that cadets had a high level of readiness before sea practice, especially in understanding tasks in the engine room and the ship's engine system. The main obstacles faced are the lack of practical experience as well as the gap between on-campus learning and operational conditions on board. On the other hand, adaptability, working closely with the crew, and implementing safety procedures are in the high category. These findings show that marine practice plays an important role in integrating theoretical knowledge with real-world work experience and supporting the reinforcement of experiential learning through practice optimization, simulators, and collaboration with the shipping industry.
