Abstract

The case study on the tugboat award 1 experienced problems with the propeller which made it possible to be out of balance. The purpose of this research is to find out the causes of unbalanced propellers on ships and how to overcome them. The use of research methods using observation, interviews and data analysis by observing, reviewing and analyzing objects or problems that will be examined directly so that the data obtained is objective because the author experienced it himself and was at the ship docking location when the work of the propeller was not perfect. From the data obtained, then an analysis of descriptive qualitative methods was carried out. The results of this study state that the unbalanced propeller is caused by fouling, erosion, cracks, and deformation of the propeller blades. Possible triggering factors include long absence of maintenance, old components, and negligence in operation. An unbalanced propeller if not handled immediately is feared to cause damage to other components such as damage to the stern tube which results in leaks and can endanger the ship.

Abstract

Working on a ship might make people see something more than others, for example, high salaries continue to be able to go see new places for free and so on. The author who is a ship captain must be able to provide a sense of security to his crew, manage crews who come from various countries which of course have different characteristics and so on. However, the most important thing here is how can a captain be able to compliance and provide understanding to his subordinates about understanding SOP so that work accidents can be minimized. Referring to the above, here I am conducting research on understanding K3 and observing SOPs on the level of work accidents on Swissco Garnet ships, the company Allianz Shimanagement LLC. The research method here I use a quantitative approach with explanatory research. The results of the study show that compliance with OSH and understanding of SOP is closely related to the level of work accidents on the AHTS Swissco Garnet ship in the company Allianz SHipmanagement LLC. And it is hoped that from the results of this study the author can provide an understanding to the crew that understanding K3 and complying with the SOP that has been made by the company is also a tool that can prevent someone from work accidents.

Abstract

Shipping safety is a must, it is an obligation for everyone to carry it out. And the fulfillment of safety facilities is a must that must be carried out or fulfilled by shipping companies. Shipping safety is inseparable from the people on board, namely the Ship's Crew (ABK), namely people who become the crew of the ship and the Nakoda as its leader. This study aims to prove the relationship between the level of knowledge and the fulfillment of shipping safety facilities. . The study used 5 ships and 61 samples and analyzed using kai squared . The results of the study show that there is a significant relationship between the level of knowledge and the fulfillment of shipping safety facilities.

Abstract

A level switch is a device that detects the height or level of a volume of liquid in a tube or tank, we take an example, for example a level switch is installed in a water tank to detect the amount or volume of fuel entering the tank, then this device is connected to a pumping machine. fuel, when the volume of fuel in the tube has reached a certain level (high) and is detected by the sensor, the level switch sensor will work because the front of the level switch is submerged in oil, at that time the level switch will instruct the fuel pump engine to stop rotating, in the sense that the level switch will cut off the flow of current leading to the pumping machine. The level switch system has a fairly simple way of working. When the oil reaches half of the lower ballast (low level) then two sinkers will hang where the total weight will be able to pull the switch on the switch body at the top. The switch that is attracted to the ballast will make the relay contact close and electric current will flow through the cable to the fuel control engine which then starts and fills fuel into the tank until it reaches a high level.

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.
