Abstract

The cadets' ability to complete the given language activity and understand the speaking competency constitutes success in speaking English. As a result, the video conference implementation for the Speaking for Formal Interactions course at Ivet University's third-semester cadets in Ship Electrical Engineering has gone off without a hitch. Utilizing different techniques, plans of action, and extra supporting systems like Quizizz, WhatsApp Groups, Zoom Meetings, and others helps with implementation. Speaking professors and cadets also mostly benefit from video conferences in terms of efficacy, ease of connection, technology, and cost rather than experiencing any drawbacks In order to collect the data, a number of approaches, including observation, interviewing, and a questionnaire, were employed to collect the data. The human instrument, observation sheet, questionnaire, and interview guide were study tools at the same time. A technique from Miles and Hubberman (1991) was used to analyze the data that had been gathered. Additionally, the current study used methodological triangulation, which is the use of multiple data-collection techniques, including observation, interview, and questionnaire. In addition to using video conferencing for speaking, the attitudes of the lecturers and the cadets regarding using video conferencing for Speaking for Formal Interactions were also examined. The 15 items in the questionnaire were divided into four categories based on factors including video conferencing efficacy, accessibility, cost, and technology.

Abstract

The cylinder in the internal combustion engine is one of the main parts, where this part is where the piston works. Due to the importance of the piston and cylinder functions in the combustion process in diesel engines, it is necessary to have a good maintenance schedule, as well as repairs to overcome existing problems. Among the things that can be done if the piston and cylinder damage is severe is to replace the piston (oversize). This study aims to identify wear problems on the cylinder liner and piston of diesel engines. Measurement of cylinder liner clearance is carried out to determine wear and tear by comparing it with the initial standard diameter. The piston diameter measurement is carried out to determine its wear by comparing it with the initial standard diameter size. The biggest wear occurs in cylinder liner number 4 which is 0.42 mm. After measuring the diesel engine with 6 cylinders, the largest wear result was obtained on cylinder liner number 4, which was 0.42 mm. The biggest piston wear occurs on piston number 1 which is 0.65mm. Need to oversize almost all cylinders except for cylinder number 2.

Abstract

The diesel engine is a vital component that serves as the ship's main propulsion system. This engine plays a crucial role in the efficiency and operational stability of the ship. One of the important parts of a diesel engine is the governor, which functions to regulate the engine's rotational speed to keep it stable. Problems with the governor can cause engine speed instability, leading to operational issues, reduced fuel efficiency, and a higher risk of damage. The study uses observational methods to identify the main causes of engine speed instability due to governor failure. Basic data include measurements and observations, maintenance history, and records of past failures. Observations on engine speed instability caused by governor failure focus on electrical issues, material wear, and extreme temperatures. This research emphasizes the importance of good and routine maintenance for the governor. Maintenance includes regular inspections, electrical maintenance, and the replacement of worn components. The research results are expected to provide practical recommendations for ship technicians to improve maintenance activities and address diesel engine speed instability issues. Implementing the findings of this research is expected to enhance the overall safety and operational efficiency of the ship

Abstract

The use of HVAC on ships is very necessary considering that the environmental conditions are relatively hot when the ship is operated, so to provide comfort to the ship's crew it is necessary to ensure that the temperature and humidity of the ship's accommodation spaces are maintained. One of the main problems in HVAC planning is determining the right cooling machine capacity, so that the cooling goal of providing cool and comfortable air conditions can be achieved. The selection of cooling engine capacity is chosen based on the total cooling load on the ship. The cooling load calculation is carried out using equations and calculation steps in accordance with ISO 7547 of 2002. The existing heat load sources are the total of the transmission heat load that propagates through the walls, ceiling and floor of the room, the heat load from the room occupants, the radiation heat load that passes through the room. walls, heat load from room lighting, and heat load from electronic equipment used in the room. Calculation of the cooling load for the accommodation space of the General Cargo KM Pratiwi 2055 DWT ship identified transmission heat of 3528 Watts, room occupant heat of 9910 Watts, radiant heat through the walls of 3700 Watts, room lighting heat of 1340 Watts, and heat load from equipment electronics of 5900 Watts. The total cooling load from the cooling machine is 24,378 Watts.
