Abstract

Character building is very essential for cadets. As future leaders and officers on commercial ships, they are expected to have strong personalities, be disciplined, be responsible, have high integrity, and be able to work together in a team. Based on this issue, this research aims to analyze the effect of nurturing programs, boarding schools, and social media on the character-building of Politeknik Ilmu Pelayaran (PIP) Semarang cadets. This research used a quantitative method with respondents PIP Semarang cadets from the Nautical Studies, Marine Engineering, and Port and Shipping Management Study Program with a sample of 200 cadets. Sampling was conducted using a questionnaire via Google Form with a Likert scale of 1 to 4. Data obtained from the questionnaire were analyzed using the SPSS 21st version program. The results of this research show that the nurturing program has a very significant influence on the character-building of cadets. Thus, if the nurturing program can be implemented well and correctly according to established norms and regulations, the character of the cadets will be built well and meet the expectations of PIP Semarang. In addition, the boarding school system has a significant influence on the character-building of cadets. A well-built Boarding School system will assist in shaping the characters of PIP Semarang cadets. Lastly, the use of social media does not significantly influence cadets' character-building since there is a regulation related to the limitation of the use of communication devices and the internet.

Abstract

The maritime transportation system plays a crucial role in international trade, with ships serving as the main means of transporting goods and passengers. One of the vital components in ship operations is the main engine, which requires a cooling system to maintain temperature stability. The jacket cooling fresh water system is the preferred choice because it can reduce the risks of corrosion and scale formation, which often occur in sea water-based cooling systems. The MV. Lumoso Karunia VIII's main engine fresh water cooling system overheated, reaching 90ºC and damaging the cylinder cover, which consequently disrupted operations. This study investigates the causes, effects, and preventative measures for this temperature spike in the engine's jacket cooling water system. A qualitative descriptive approach, using interviews and direct observation, was employed, with data analyzed using the SHEL model. Interviews were conducted with the chief engineer, second engineer, and fourth engineer. The factors causing overheating in temperature of jacket cooling fresh water in main engine include inadequate maintenance of the heat exchanger, blockage in the inlet that obstructs the flow of fresh water to the main engine, contamination in the cooling water, and dirt accumulation. The impact of the increased temperature in the jacket cooling fresh water of the main engine is engine overheating and financial losses. Efforts to prevent the overheating jacket cooling fresh water temperature in the main engine include regular maintenance and consistent inspections according to the Planned Maintenance System (PMS), cleaning of the heat exchanger and dirty expansion tank, as well as improving communication among the crew in managing the maintenance of the cooling system.

Abstract

The density of shipping activities today, every ship must have machinery that is always in good condition. Therefore, the implementation of maintenance on every machinery on the ship is very important. However, according to reality, many machinists or engineers do not pay attention to the importance of maintenance on machinery. The machinery maintenance system or Plan Maintenance System (PMS) is a routine maintenance schedule for existing machinery on the ship so that its condition remains optimal. Researchers took the title of this study because they wanted to increase their understanding of the importance of routine maintenance of machinery on ships so that the machinery continues to work optimally. Researchers developed from the importance of maintenance and associated with the application of informatics techniques so that researchers wanted to design an application that functions for an android-based Plan Maintenance System information system that can be used as a maintenance reminder and engine maintenance results. Researchers used the Research and Development method to complete the research conducted with the development of Borg and Gall with the development of 10 steps, but researchers only took 9 steps because researchers did not make products in bulk. The 9 steps are the potential problem stage, information gathering, initial product design, product trial I, product revision I, design validation, product revision II, product trial II, and final product finalisation. The results of the research on making the android-based Plan Maintenance System information system application can be done using all types of computers that have Native Script installed to do the application coding process. This Plan Maintenance System application can be used by cadets of the Semarang Polytechnic of Shipping Science and Engineers who are on board as a means of knowledge and as an information system regarding maintenance of machinery spare parts
