Abstract

Abstract This study applied Research and Development (R&D) study which developed game application based English learning. The purpose of this study is to improve the leaner’s vocabulary and reduce their anxiety in mastering English. Vocational maritime students had problem in memorizing vocabularies and based on the result of need analysis, they need a media that can ease them in learning English. This study followed some steps in developing the game application, those were; assessing need analysis, writing performance objective, instructional strategy’s development, instructional materials’ development and selection, implementation of formative and summative evaluation. The instrument of this study were questionnaire and interview to gain students response in need analysis process and in evaluation. OCEAN can catch the learner’s attention and decrease their anxiety in learning English. Most of students agree if the game improves their motivation and they can enjoy playing the game. The development of this game as an educational game has good impact and responses even though some improvements are needed.

Abstract

Media as an important part of English teaching has been developed massively. The role of media in teaching English cannot be separated from students and teachers. This study aims to measure the effect of media that has been developed by the writer in order to know the effectiveness of the media itself in improving students’ vocabulary. OCEAN is a media development that provide some features to improve students’ English skill. This study implemented and tested OCEAN to measure the effectiveness of the media. This study used experimental quantitative research and T-test to gain and analyze the data. The result said that the average value of English vocabulary from pre-test is 65.81 ± 5.19, which is lower than the average value of English vocabulary in the post-test, which is 82.12 ± 5.86. To find out whether there is a significant increase in the average variable value of English vocabulary from the pre to post, the Wilcoxon test was carried out. From the Wilcoxon test, it was found that the calculated Z value was smaller than the -Z table (-4,594 < -1,960), and the p-value was smaller than α (0,000 < 0,050), so the decision was taken that H0 was rejected, which means that there is a significant difference in the average between pre and post-test. The conclusion of this study showed that the media is effective in teaching English vocabulary.

Abstract

The decrease in intercooler effectiveness in a ship's main engine can significantly affect performance and fuel efficiency. This final project aims to analyze the impact of the decrease in intercooler effectiveness on combustion air pressure and fuel consumption of the main engine of the Ningbo 8300 MV Semangat Mas. The research was conducted using observation methods and data analysis from measurements obtained during the ship's operation. The collected data includes combustion air pressure, intake air temperature, and fuel consumption under normal engine conditions and conditions with decreased intercooler effectiveness. The results of the study show that the decrease in intercooler effectiveness causes an increase in intake air temperature, which in turn raises combustion air pressure and fuel consumption. This phenomenon indicates that the decrease in intercooler performance can worsen fuel efficiency and reduce overall engine performance. The conclusion of this research highlights the importance of routine intercooler maintenance to ensure the optimal performance of the ship's main engine, reduce fuel consumption, and improve the ship's operational efficiency.

Abstract

Gearbox is a vital component in the ship propulsion system that functions to transmit power from the main engine to the propeller. On the MV. Mas Initiative, found a discrepancy between the gearbox rotation ratio with the RPM of the main engine, which has an impact on increasing the lubrication temperature of the gearbox lubricating oil to exceed the optimal limit. This condition can reduce lubrication efficiency, accelerate component wear, andreduce overall ship performance. This study aims to analyze the factors that cause gearbox ratio mismatch, evaluate its impact on lubricant temperature, and develop technical recommendations to overcome these problems. The method used is descriptive qualitative approach through direct observation, interviews with the crew, and literature studies. The results showed that the main causes of this discrepancy include damage to gearbox components, a non-optimal lubrication system, as well as a lack of regular maintenance. The high temperature of the lubricant has an impact on decreasing the viscosity of the oil and decreasing the efficiency of power transmission. Recommended solutions include regular cleaning of the oil cooler and filter, checking the pressure of the oil pump, as well as regular oil quality testing. It is expectedthat the results of this study canbe a referencein gearbox maintenance to improve the reliability and operational efficiency of the ship.

Abstract

The main engine is the primary component in a ship's propulsion system, responsible for the continuity of its voyages. A critical supporting system for the main engine's performance is the fuel system. This system supplies fuel at the correct pressure and quantity to the combustion chamber, ensuring optimal combustion. Any disruption or irregularity in the fuel system can cause the main engine's performance to decline, potentially leading to serious damage that hinders the ship's operation. This study aims to analyze the factors causing fuel inefficiency in the main engine and to formulate technical recommendations to address these issues. The research uses a descriptive qualitative approach through direct observation, interviews with the ship's crew, and a literature review. The results indicate that the main causes of these issues include:An increase in exhaust gas temperature due to the fuel injector's operating hours exceeding its maintenance schedule, leading to the injector not functioning optimally.The main engine shutting down unexpectedly due to dirt and water in the fuel, which interfered with the fuel purifier's operation, resulting in poor fuel quality.The suggested solutions include installing a separator to achieve better fuel quality and increasing the temperature of the MFO fuel. It is hoped that the findings of this research can serve as a reference for fuel system maintenance to improve the ship's operational reliability and efficiency.
