Abstract

Sea transportation is seen as the most effective means of responding to the high demand for a commodity. The development of industry 4.0 and society 5.0 has a big influence on the economic growth of a country. Loading and unloading must go well, so efforts are needed to ensure its implementation. Delay in unloading due to hydraulic leakage. The captain and guard officer as more experienced parties are expected to make efforts to prevent it. Coordinating work when unloading shows that the ship has followed procedures and efforts to repair hydraulic leaks. The method used by researchers to analyze problems is the fishbone analysis method. Research data obtained from primary data and secondary data, while data collection was obtained from observations, interviews, descriptive and literature. Fishbone analysis aims as an effort made to change the data from the results of a study into simpler information, so that it is easy to use to draw conclusions. Based on the results of this study, hydraulic maintenance was further improved and procurement of spare parts continued to be pursued by the ship. In addition, the company's management also affects the performance of the crew on the ship so that there is a need for improvement in the company's management of the ship.

Abstract

In the administration of President Jokowi Widodo has established a national maritime policy through the concept of Indonesia as a World Maritime Axis (PMD). This concept was conveyed by President Jokowi Widodo at the 9th East Asia Summit (EAS), 13 November 2014. Maritime security is not only the main task of the Navy as the main backbone of a country's maritime security, but cannot be separated from the support of non-military (civilian) agencies whose duties and functions are closely attached to the aspects of maritime security and safety surveillance, in this case, the Coast. Guard (Coast Guard). This research is qualitative research and uses descriptive analysis aimed at describing the tasks and problems faced by the Sea and Coast Guard Unit as a Sea and Coast Guard in the Work Environment Area (DLKr) and the Environmental Interest Area (DLKp) Tanjung Mas Port Semarang, as well as relating to the policies taken by KSOP Tanjung Mas Semarang in overcoming problems that arise in the field related to KPLP functions based on Law Number 17 of 2008 concerning Shipping.

Abstract

Exhaust gas systems in diesel generators require heat-resistant materials. The use of titanium metal is designed for exhaust gas system materials. Material coating system for high temperature applications known as Thermal Barrier Coating (TBC) has been applied to diesel engine materials. TB has the ability to reduce temperature on the surface and protect thermal oxidation at high temperatures. This research discusses the coating of hydroxyapatite (HA) ceramic material on titanium metal which will be used as a flue gas system material with variations in coating temperature. The method used is testing the chemical composition of titanium metal, macro microscope testing of ceramic coatings and adhesion testing with variable temperature specimens 7000C, 8000C and 9000C.

Abstract

Vocational education is a higher education diploma program that prepares students for jobs with certain applied skills to the Associate Expert or Applied Bachelor program. STEM literacy can bridge higher education with competent human resource graduates in the maritime sector that the industry needs because in vocational education through the revitalization program, the industry must collaborate with the needs of the world of work. The research method uses conceptual description analysis on the problem of STEM literacy needs in maritime colleges. STEM literacy includes Science, Technology, Engineering, and Mathematics literacy. Some of the established indicators can use several references from AAAS, ABET, NRC, NCTM, OECD, and ITEA. According to Bloom's taxonomist, the ability level of cadets according to the author can be implemented at levels C4, C5, and C6 for the cognitive domain. The affective domain on attitudes, beliefs, self-esteem, self-confidence, and motivation, and the psychometric domain on actions that indicate motor skills such as in the use of instruments or tools that are precise and accurate.

Abstract

National defense specifically for the marine dimension has the task of upholding sovereignty and maintaining the territorial integrity of the Republic of Indonesia. So that it takes a large number of warships of the Republic of Indonesia. Which are procured through domestic and foreign projects. Specifically for foreign ship procurement projects, the government through Law Number 16 of 2012 concerning the Defense Industry seeks to maximize the use of domestic production to empower the domestic defense industry and improve the welfare of the national economy. This research seeks to examine the process of handling Import documents in PT PAL Surabaya so that the completion of the project at PT PAL Surabaya is not hampered. Descriptive qualitative methods and samples were taken at PT PAL Surabaya. From the research results, it can be concluded: PT PAL Indonesia to complete its customs clearance in the customs area is not optimal. There needs to be supervision so that it can run as planned. The SP-1 issued by the Ministry of Health has been issued for a long time. So that it raises the burden of high storage and demurrage costs, to avoid it PT PAL submits Eigen-losing approval to KPPBC according to the Eigen-losing procedure, including the timeframe for hoarding, and responsibility for import duties as well as demurrage and storage costs. hampered shipbuilding production is not according to the planned target.

Abstract

The purpose of this paper is to analyze the causes of delay in the work response of the actuator in controlling the action on the fuel injection pump rack when the ship is sailing. An actuator is a propulsion device that is driven by a pneumatic system (compressed air system) or a hydraulic system (hydraulic oil media) in the world of control applied as a safety device for machines. The accuracy of the actuator process as a tool used in security equipment on the ship's main engine plays a very important role in keeping the main propulsion engine working in safe conditions. Against the background of the weak work response of the actuator as a fuel rack propulsion on the fuel injection pump which results in damage to the main engine due to Overspeed. The problem that will be analyzed is the number of things that make the actuator work incompatible with its function. In its use, the actuator gets a signal command from the tachometer which functions to read the engine speed, which was previously sent to the Safety System Unit (SSU) to be processed and compared with the desired value/set according to the standard manual book of the machine. The method used is to use a qualitative descriptive approach. The conclusion of this paper is the need for good maintenance in the actuator system to prevent it from failing to protect engine work, such as checking the work response in pushing, pneumatic, or hydraulic drive systems, calibrating the output value of the tachometer or the system from the Safety System Unit (SSU).

Abstract

A freshwater generator is one of the auxiliary machines onboard which functions to convert seawater into freshwater by distilling it in a vacuum. Fresh water on the ship is very important for crew accommodation and also for the smooth work of machinery on ships that use freshwater for cooling media or for other purposes. The working principle of a freshwater generator is to separate the salt content in seawater by evaporating it in a vacuum so that the boiling point decreases and the water can evaporate below a temperature of 100oC. Problems and disturbances in the freshwater generator will affect the amount of freshwater production, therefore the condition of the auxiliary machine must be maintained. In this study, the authors used the fishbone analysis method to describe the factors that caused the vacuum that was not optimal and to find out the causes, impacts, and efforts made to overcome these problems. Based on the results of research that the author has done in MV. During the practice, Glovis Daylight concluded that the inadequate vacuum in the freshwater generator was caused by low ejector pump pressure, broken mechanical seal on the ejector pump, dirty strainer, and crust on the condenser and evaporator plates. The resulting impact is that the resulting freshwater production will decrease. Efforts to overcome this require routine maintenance according to the manual book, replacement of mechanical seals, cleaning strainer, and descaling of the condenser and evaporator plates.
