Abstract

The International Convention on Training. Certification and Watchkeeping Standards for Seafarers 1978 (STCW1978), as amended in 1995 and last amended in 2010 the Manila Amendment 2010was intended to implement all changes agreed upon at STCW-95 by incorporating new technology. The time given by IMO to implement the 2010 STCW amendment convention to all its members in implementing changes is 5 years ending on January 1, 2017. This affects the institutions that provide education and training are required to be able to fulfill all changes and requirements. Shipping schools in Indonesia are required to apply the Minister of Transportation Regulation Number PM 70 of 2013 concerning Education and Training, Certification and the Guarding Service of Seafarers. The research method used is Indepth Interview or in-depth interviews with the population and samples are schools and shipping academies in the city of Semarang. Interviews were used to explore data related to the implementation of the 2010 STCWamendment rules in the schools concerned. The research data obtained are in the form of interviews written. The results of the interviews were then analyzed by understanding the relationship between the questions with each other by comparing the technical rules for the implementation of education and training for seafarers. The results of the study on the evaluation of the implementation of the 2010 amendment STCWas outlined in reference to the Minister of Transportation Regulation Number PM 70of 2013 obtained several conclusions. Shipping schools have difficulty meeting facilities including simulators. The biggest difficulty faced is funding because the price of simulators is quite expensive and the instructors are competent with seafarers. The role of the government is still very lacking in providing support and assistance in meeting the requirements that must exist for the smooth process of education.

Abstract

Awareness of sailing safety ls vital and must be prioritized. Various incidents of ship accidents, starting from burning ships and sinking became a separate evaluation material for Indonesia which declared it to be the world's maritime axis. The problem of the lack of safety equipment available on ships are found in cases of passenger ship accidents in Indonesia. This is also found in fishing vessels belonging to groups and individuals. The main reason stated by the ship owner is that the procurement of safety equipments requires no small amount of funds, and priority needs of each of the different safety equipments so that not all equipment need to be fulfilled, In addition, the low level of education and skills also affects safety awareness. The type of research used is Explanatory Research which aims to analyze whether or not the influence of the amount of fishermen's income on sailing safety awareness is mediated by education level. The number of research samples is 59 respondents who are fishermen on the North Coast of Java (Semarang, Demak, and Kendal). The research data was obtained through filling out questionnaires using a Likert scale with a range of 5. In addition, it was also strengthened by follow-up interviews to support the results of research data processing. From the results of the research data obtained results: (1) the amount of income did not affect the level of education, (2) the amount of income did not affect sailing safety awareness. (3) the level of education had a positive effect on sailing safety awareness and (4) the level of education was not mediates the effect of the amount of income on sailing safety awareness.

Abstract

Semarang Growth Centre (SGC) merupakan salah satu lembaga pengembangan pendidikan tinggi milik Pemerintah Republik Indonesia di bawah Direktorat Jenderal Pendidikan Tinggi yang berdiri sejak tahun 1993. Pada perkembangannya di tahun 2012 SGC diusulkan berubah menjadi Politeknik Maritim Negeri Indonesia (Polimarin). Perubahan organisasi dalam penelitian ini berdampak pada manajemen organisasi, faktor sosial, metode, aspek manusia, perilaku kerja, minat, pengalaman, prestasi kerja, tanggung jawab dan motivasi. Hasil penelitian yang perlu diperhatikan adalah faktor manajemen organisasi yang memiliki nilai persepsi terendah dari anggota organisasi dengan prosentase mendekati 40%. Terjadinya penilaian negatif tersebut disebabkan perlunya proses penyesuaian antara pelaksanaan di lapangan dengan aturan baku dari pemerintah sebagai lembaga baru. Selain itu belum dilaksanakannya prosedur manajemen secara konsisten dan kurangnya koordinasi antar bagian dalam pelaksanaan beberapa pekerjaan. Penelitian ini merupakan penelitian kualitatif dengan deskriptif analisis. Pengumpulan data dilakukan menggunakan kuesioner, wawancara dan studi pustaka. Sampel penelitian adalah 30 orang karyawan yang bekerja di Polimarin sejak masih bernama SGC. Analisa data penelitian dilakukan dengan menjabarkan hasil dalam 41 tabel tunggal, sehingga memperoleh simpulan penelitian. Hasil wawancara dan studi pustaka digunakan untuk memperkuat hasil analisa data kuesioner.

Abstract

This study discusses the design of a Blow Off Valve (BOV) valve in a turbocharger system on a diesel engine on board, BOV is used to release the air pressure contained in the scavenge air chamber when it experiences an increase in pressure due to the reduced frequency of opening the air duct that enters cylinder chamber. The purpose of this study is to analyze the selection of blow off valve designs that are in accordance with the need to reduce surge phenomena on diesel engines of ships using turbocharge and to analyze the quality/ performance results of the blow off valve through Solidwork software. The air pressure will still put pressure to get out of the system. This will cause the pressure in the system to increase and this air pressure will flow back to the turbine and will cause damage to the turbocharge component. This phenomenon is called turbocharge surging. So, air flow is very important to ensure that no air pressure flows back into the turbocharge. The selection of valves in accordance with the design techniques of several alternative choices is very decisive. Numerical calculations and spring performance analysis of a selected valve are carried out using solidwork software.
