Abstract

The Indonesian Sea is very important for the Republic of Indonesia, namely the sea as a medium for unifying the nation, the sea as a medium of communication, the sea as a resource medium, the sea as a medium of defense and security, and the sea as a medium of diplomacy. Freight or sea transportation in Indonesia has an important role in advancing and expediting domestic and foreign trade. Allianz Middle East's obligations or responsibilities as a transportation company and the passenger's right to enjoy these facilities cannot be separated from the element of passenger safety which is the main priority. The research aims to determine Allianz Middle East transportation services on offshore service vessels. To find out the safety of passengers and crew on the Pioneer ship at Allianz Middle East LLC. The test results show a positive and significant influence between service on the management commitment of the Allianz Middle East ship, and other tests show a positive and significant influence between the safety assurance variable and the management commitment variable.

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.

Abstract

The main objective of this research to find out speaking problems’ students English at the fifth semester of Ship electrical engineering of Maritime Faculty of Ivet University The method of this research was qualitative descriptive, which describe problems in speaking English by the students, the population of this research was conduct students at the fifth semester of English education department at Ship electrical engineering of Ivet University. A sample of this research was taken by purposive sampling which consisted of 20 statements to 35 students. To get data, the researcher uses questionnaires and class observation. Based on the research findings, the result of the research showed that students problems fluency and accuracy in speaking English. There are inhibition, that consists of students feel shy of being attention when speak English, they cannot remember anything to say and they do not have any motivation to express themselves, worried about making mistakes, afraid of being criticized when speak English incorrect, it is caused by their low understanding in grammar, low vocabullary, and low level of pronounciation mastery. The next problem is nothing to say, students afraid of being faulted, have no idea to speak English, and lazy to speak English, it is caused by uninteresting topic, and difficult topic

Abstract

Penelitian ini bertujuan untuk mengetahui kekasaran permukaan material baja dengan jenis ST 37 akibat variasi proses pengasahan batu gerinda. Sebagai proses finishing pada produk manufaktur, maka proses menggerinda datar perlu diketahui parameter asahan batu yang tepat. Penggunaan ST 37 sendiri menjadi pertimbangan karena kebutuhan material benda kerja untuk pendidikan di laboratorium manufaktur. Metode penelitian pendekatan eksperimen pada 3 spesimen dengan 3 variasi parameter pengasahan batu gerinda. Pengambilan data enggunakan konsep duplo untuk memperoleh data lebih dari satu. Setiap data sampel mempunyai 6 pengukuran. Hasil yang diperoleh yaitu, variasi 1 mendapat nilai kekasaran permukaan N6 dengan rata-rata kekasaran 0,839 ?m.Variasi 2 memperoleh nilai kekasaran permukaan N6 dengan nilai rata-rata kekasaran 0,650 ?m. Variasi 3 didapatkan nilai kekasaran permukaan N8 dengan nilai rata-rata 2,685 ?m. Sehingga, dapat disimpulkan bahwa pengasahan batu gerinda berpengaruh terhadap perubahan nilai kekasaran permukaan, baik variasi 1 maupun 2.

Abstract

Working Law number 17 of 2008 is a reference for sea transportation in relation to containers and as an archipelagic country that has vast seas and long coastlines, the maritime and maritime sectors are very strategic for Indonesia in terms of the economic and environmental aspects which are suitable for sea transportation for Container: The definition of a container is a tool for transporting goods in whole/in part/closed form so that it takes the form of a crate or crate and is intended to be filled with the goods to be transported. In order to promote non-oil and gas exports, the Government through the Department of Transportation has taken several important and strategic steps in its involvement in achieving the goal of procuring container ships so as to smooth and stabilize the foreign trade balance, in addition to obtaining reasonable cargo. Moreover, in this era of containerization, it is not enough to just build a port, but it also needs to be supported by personnel in the field, work systems and procedures as well as suggestions and other infrastructure that are in accordance with the value and benefits of the container itself.

Abstract

The dieselEgine that drives the ship's electric generator must always be maintained in good condition, because as a electrical power plant throughout the ship, without an electrict the ship cannot function normally. To keep it in top condition and prevent black out, diesel maintenance must be carried out according to standards so that this does not happen after damage has been repaired. One thing that must be done and reported to the classification is the crankshaft inspection. The aim of this research is to find out how much deflection occurs after several years of diesel engine operation, has it exceeded the specified standards? If it has exceeded how to return it to standard condition? The methodology used is quantitative and qualitative, by measuring directly on objects and comparing with existing standards, qualitative by direct observation in the field and comparing with existing references. From the existing results, conditions were obtained that exceeded standards, which were then repaired. The benefit of this research is that it provides an overview of how to carry out maintenance, measure, assess, and how to overcome problems that occur with the engine.
