Abstract

The energy crisis has required the government to develop and utilize a renewable energy. Indonesia has a national jurisdiction area of ± 7.8 million km² with 2/3 of its territory being the sea of ± 5.9 million km². With this large sea area, it is a great potential for Indonesia to be able to develop alternative energy resources in the maritime sector amid the problem of fossil energy resources whose capacity is decreasing. Alternative energy in the maritime sector that can be developed include energy that utilizes ocean waves, ocean currents, tides, and ocean temperature differences. This study aims to determine the alternative energy of the maritime sector by reviewing from technical and financial aspects, political, economic, social and technological aspects. The method used is technical analysis, financial analysis, PEST analysis, and Fuzzy MCDM. The first step in this process is the mapping of the technical, financial, political, economic, social and technological aspects of each energy alternative with technical, financial and PEST analysis. Furthermore, with the Fuzzy MCDM method an alternative energy development selection model was made by assessing the performance of each. Based on the results of data processing shows the ranking of determining the alternative energy of the maritime sector with the first is the source of ocean current energy, the second is tidal energy, the third is wave energy and the last is Ocean Thermal Energy Conversion (OTEC). Keywords: Alternative Energy Resources, PEST, Fuzzy MCDM

Abstract

Technology and information are currently growing rapidly so that computers are no longer used as a computing tool, but have turned into a machine that has the same ability as the human brain, especially searching on a very large fingerprint database. Supervision through a security system that is designed is very helpful for the performance of the Indonesian Navy code personnel who serve in the communication unit, especially the code room. The Code Room is one of the important rooms specifically used as a place for coding activities for the Indonesian Navy. In addition, the code room also functions as a news center for both confidential and open news. This security system using fingerprint (Fingerprint) and Qrcode (Quick Response Code) is designed to be able to control the door with serial communication from android to microcontroller (wemoss) and personal computer (PC) so that it will move the selenoid (door lock) to open the door on condition fingerprint and qrcode are recognized by the system. The level of success of this security system depends on the user's fingerprint identification and the validity of the data stored in the database. The test results of the security system developed in this final project show a success rate of 98%. This tool is expected to be used as a Security System for the Password Room at the Satkom Lantamal V Surabaya. Keywords: Fingerprint and Quick Response Code

Abstract

By the development of the time, diesel fuel is made from petroleum which is decreasing in number. Besides that, the emissions produced from burning diesel fuel can also cause air pollution. One of the methods used to minimize the use of diesel fuel and air pollution is by using emulsion fuel. therefore, a precautionary measure is required in preparing a reserve fuel source for Indonesian war ships. And one of the options is with emission diesel fuel. From the results of laboratory trials there was an increase in density, viscosity, flash point, cetane and TAN numbers and a decrease in residue, Lower Heating Value and calorific value. The performance test results show an increase in SFOC and thermal efficiency, but the power, torque and BMEP have decreased. So, it can be concluded that the emulsion HSD has decreased performance but can reduce emissions from the combustion process. So, it is hoped that emission diesel fuel can be used as an alternative as well as a solution to the limitations of diesel fuel in the future, so that it can support tni al operations in the future.

Abstract

The North Natuna Sea is still a hot topic of discussion both nationally, regionally and internationally. The discussion is inseparable from the interest in the potential of natural resources and energy contained therein. The problems with the boundaries of the Indonesian Exclusive Economic Zone (ZEEI) and the territorial claims in the South China Sea (SCS) by China make this problem more complex so that it is necessary to immediately get serious handling to prevent risks and losses for the national interest. The presence of elements of the naval presence in the North Natuna Sea is a form of handling in the field of maritime operations which aims to maintain maritime security and protect the sovereignty of the Unitary State of the Republic of Indonesia (NKRI) from various threats. Through this article, I would like to provide an overview of Indonesian Navy diplomacy through its naval presence in the North Natuna Sea and its influence on the effectiveness of maritime operations carried out based on the results of research using quantitative methods. Naval presence is part of the Indonesian Navy's diplomacy in dealing with the problems that occur as well as an effort to maintain world recognition of the Republic of Indonesia.

Abstract

Sea ​​transportation mode is still the favourite in the business world because of its high carrying capacity (capacity) and more competitive costs compared to other modes of transportation. As a country that has a vast marine area, Indonesia certainly has many problems related to its marine area. Indonesia faces various potential trans-national crimes that usually occur at sea such as illegal fishing, smuggling of goods, drugs and human, terrorism and piracy. Based on the complex conditions of the potential problems that arise in the maritime sector, all stakeholders and law enforcement officers at sea need integrated maritime information management to support their duties in maintaining security in Indonesia's waters. Therefore, it is hoped that the use big data of maritime information will be able to help stake holders involved in overcoming these problems.

Abstract

Indonesian domestic workers have been an interesting issue for several years. The existence of the workers, in one side, has played significant roles in generating income, reducing poverty, and generating economic development of the sending country. But in another side, they have also created complicated problems. The problems have frequently involved multiple stakeholders including governmental, non-governmental institution, and private sectors. Therefore, this study focuses on explaining Government participation in managing Indonesian domestic workers in China. China was chosen due to the number of the domestic workers. In order to explain the phenomenon, the researchers used qualitative research method. Consequently, the primary data was collected from interview. In addition, documentary analysis was also used in order to support the data. The study showed that there are at least some Government involved in managing Indonesian domestic workers such as National Agency of Placement and Protection of Indonesian Workers, Private Agencies in sending and receiving country, Ministry of Labor, and Ministry of Foreign Affairs. There are three processes of worker placement namely pre-placement, while-placement, and post placement. The private agencies participated practically in almost all of the process including recruitment, providing education and training, and placement the workers. While, other Government participate in providing administrative process such as providing agreement, documents needed, legalizing private agencies, and collecting the data of the labors. However, administrative process was not run properly. It was because the workers and private sectors have to report their conducting activities. This condition gave impact to the lack of control to the activities. This was also exacerbated by the lack of participation from the workers. They don’t have any information about the job and power to get protection. It was because of the existence of the law and lack of education. Therefore, knowledge about job, law, and involved Government was needed to increase participation and protection of the worker.

Abstract

Warship ability owned by Indonesian Navy is expected to have deterrence effect on other countries that want to disturb the sovereignty of Indonesia. Therefore, the right decision is needed to determine which warship should be chosen to carry out the task of guarding Indonesia's territorial waters. The newest warship that has a deterrence effect and is owned by the Indonesian Navy is the KRI PKR105 class. This ship has reliable capabilities both in terms of offensive and defensive because it is equipped with qualified equipment and weapons. Meanwhile, in future plans, the Indonesian Navy is interested in having a Danish-made Iver Huitfeldt class warship which also has a fairly reliable capability. In this paper, we will discuss the calculation of the capabilities of the PKR105 class and Iver Huitfeldt class which are planned to be purchased by the Indonesian Navy based on the Salvo Model. From the calculation, it can be seen that PKR105 class has the same offensive capability as Iver Huitfeldt class but Iver Huitfeldt class has higher defensive caspability than PKR105. This is because the tonnage of Iver Huitfeldt class is greater than PKR105 as one of the staying power parameters for calculating defensive ability. To overcome the shortage of PKR105 defensive capabilities, a $ 21 million CIWS can be added as one of the defensive power parameters in calculating defensive capability considering that there is still a difference in the PKR105 price of $ 285 million with the Iver Huitfeldt class price of $ 325. With this upgrade option then it can be used as one of the considerations in determining the type of ship that can be selected to increase the combat capability of the fleet. Keywords : Iver Huitfeldt Class , PKR105 class, reserve fuel, Salvo Model.
