Abstract

In accordance with the provisions and regulations in Marpol 73/78 concerning regulations for preventing marine pollution. And Marpol 73/78 Annex III regarding burning oil and waste using a Waste Oil Incinerator, requires knowledge, ability and responsibility for handling it. This world is always developing in the field of waste processing, especially those originating from ships, generally from the Engine Room, so it is better for ships to be equipped with Waste Oil Incinerator, which is a tool commonly used to burn dirty oil and other rubbish and debris on ships that can be burned. Considering its very important role on ships, the Waste Oil Incinerator is very useful and is very important equipment in efforts to prevent pollution at sea. Therefore, maintenance of the Incinerator must be carried out. With routine maintenance and repairs and in accordance with correct maintenance planning, it will provide large economic benefits for the company and participate in preserving marine ecosystems and the marine environment. However, in its implementation, errors often occur which cause a decrease in the quality of the Waste Oil Incinerator, thus damaging the marine ecosystem due to several things as follows: 1) TheWaste Oil Incinerator does not work optimally 2) Lack of maintenance of the Main Burner Incinerator on board the ship 3) Lack of maintenance on the Waste Oil Incinerator 4) Operation of the Waste Oil Incinerator not in accordance with the instructions manual.

Abstract

Fishermen's lives are less prosperous, this is due to uncertain income and operational costs in shipping and ship maintenance. The aim of this research is to analyze the welfare of fishermen in Gempol Sewu Village, Kec. Rowosari, Kendal Regency. The method used in this research is a qualitative method, with this qualitative method you can find out directly what things influence the income and welfare of fishermen by conducting interviews with fishermen in the Gempol Sewu area. The information in thisresearch is fishermen in Gempol Sewu Village who are represented by several fishermen in the area. Based on interviews and literature studies conducted, it can be concluded that the lack of welfare of fishermen is caused by several main factors. First of all, the cost of boat maintenance and safety while sailing are crucial factors that put financial pressure on fishermen. Efforts to ensure vessels remain in good condition andmaintain safety while sailing require significant investment, which may be difficult for most fishermen to afford. Concrete steps such as providing skills training programs, easy access to capital at low interest rates, and the formation of fishermen's cooperatives can be a solution to improve the welfare of fishermen and open up opportunities for them to develop businesses other than being fishermen. In this way, it is hoped that fishermen can have a more economically sustainable alternative and improve their overall standard of living.

Abstract

Welding has a very important role in engineering and metal production repairs. This is very reasonable because every construction can hardly be separated from metal which involves welding elements. Metal is widely used because it has several advantages, including being strong, rust-resistant, resistant to wear and tear and the raw materials are very economical. The development of technology and science has also had an impact on the increasing demand for metal connections of different types. Several industries that use joining by welding different types of metal include the transportation industry, car manufacturing, shipping and airplanes. One thing that can be done is connecting different types of metal which can be applied in the shipping industry. This research aims to determine the impact of variations in welding FCAW Grade A material 16 mm thick on ship deck insert plates. The use of Flux Core Arc Wellding (FCAW) is often found in the shipping industry. FCAW or what is usually called CO2 arc welding actually includes Metal Inert Gas (MIG) welding, only the protective gas is not only a noble gas such as Argon (Ar) but also CO2 gas or it could be a mixture of the two gases. The FCAW welding process is often used because the protective gas used is CO2 so it is suitable for use in welding steel construction. CO2 decomposes into CO and O2 when in contact with high temperatures. As a result of the high freezing speed, the CO gas produced is trapped in the metal which then forms cavities. Efforts are made to prevent this by providing a mixture of Si and Mn to the electrode so that no gas is trapped and no reaction occurs.

Abstract

Pentingnya tanggung jawab Port State Control sangat memiliki peranan sangat besar karena keselamatan pelayaran adalah sudah menjadi tugasnya. Tindakan-tindakan yang di lakukannya adalah untuk meningkatkan pengawasan keamanan dan keselamatan terhadap hal-hal yang berhubungan dengan pelayaran. Tugas pengawasan yang di lakukan seorang Port State Control dalam rangka pengaturan sarana dan prasarana diatas kapal. Seorang Port State Control dalam tugasnya harus juga memastikan kesadaran untuk mentaati hukum dan ketentuan perundang-undangan yang berlaku. Port State Control (PSC) adalah badan pengawasan negara pelabuhan (Port State) untuk menegakkan ketentuan-ketentuan konvensi yang berlaku di bidang keselamatan pelayaran dan perlindungan lingkungan laut serta perlindungan dan kondisi kerja awak kapal di laut dan juga melakukan pemeriksaan (survey), verifikasi (Verifications) dan sertifikasi (certifications) pada kapal asing (Foreign Ship). Hal pertama yang harus dilakukan Port State Control kepada foreign ship adalah melakukan pengecekan pada kapal dengan memeriksa dokumen/sertifikat yang ditandatangani oleh Kapten kapal. Adakalanya suatu kondisi kapal yang dijumpai banyak kekurangan-kekurangan (Deficiencies) dan tidak memenuhi standar dari ketentuan IMO. Sehingga Port State Control (PSC) memiliki wewenang untuk melakukan penahanan (Detentions).

Abstract

Pancasila as a value system has been rooted in the life of the Indonesian nation, but Pancasila is only used as an identity. However, it has never been manifested in the life of the nation and state, especially in the process of law enforcement. The research method used is normative juridical. The purpose of this study is to examine the Paradigm of Law Enforcement in Indonesia, analyze the implementation of Pancasila values ​​in current law enforcement, and to analyze the concept of Pancasila towards the practice of law enforcement in Indonesia. The weakness of law enforcement in Indonesia is caused by law enforcement officers who fail to interpret national law based on Pancasila values, such as honesty, transparency, and justice. The paradigm of law enforcement that is oriented towards the economy and power must be replaced with an approach that emphasizes morality, humanity, and social welfare in accordance with the principles of Pancasila. Reform is needed, especially in the mentality and integrity of law enforcement officers, as well as the eradication of the legal mafia that damages institutions such as the prosecutor's office and the police. Pancasila must be implemented in character formation and legal decisions to create social justice, legal justice, and legal protection for all Indonesian people, making it the basis for national development and better law enforcement.
