One of the biggest obstacles to development progress in Eastern Indonesia is the unavailability of electricity,especially on small island islands. The potential of ocean currents is one of the most renewable sources ofenergy considering that the majority of Eastern Indonesia is the ocean and has not been utilized optimally. Thepurpose of writing this paper is to reference the calculation of ocean currents for Indonesian coastal islands thathave minimal electricity. This research method uses literature studies on the morphology of the flow velocity andwind that occurs in the Capalulu Strait and the calculation of the potential of electrical energy in the CapaluluStrait so that the results of this calculation are used as one of the renewable energy methods that are able tomeet the electricity needs of island islands. which has not been electrified in Indonesia, especially in the SulaIslands, North Maluku.Keywords: Electric Energy, Ocean Flow Turbine, Renewable Energy, Strait of Capalulu

KRI is one of the main components possessed by the Indonesian Navy which has the main task of security and national defense at sea. The Termination of Operation KRI over the age of 40 results in a lack of existing KRI, so there is a need for research that represents an evaluation and analysis of the work system so that the main tasks can still be carried out. The SWOT and CIPP analysis in this study aims to identify several factors that influence the achievement of the main tasks. The results obtained are in Quadrant I (+; +) which states the status "on the track".Keywords : KRI, SWOT, CIPP.

DYNAMIC PROBABILITY OF THE INDONESIAN ARCHIPELAGO UNDERWATER DEFENCE WITH SUBMARINE SONAR Avando Bastari; Benny Sukandari; Joni Widjayanto; Dani Hutabarat

This paper study the determination of the number submarine defenses for Indonesian archipelago underwater defenses with probability method approach. In performing these calculations the authors perform the processing of data from various sources, both from the literature, the data from the relevant authorities in this regard Operations staff, Submarine Force with the elements in the form of operating reports, obtained through interviews and from the field. From these data processed probability calculation and the result obtained is inserted into the formula length / width of the waiting area submarine patrol positions further implemented method of calculating the probability to obtain optimal results. The result of this study is to know the total number of submarines are needed to maintain the strategic straits Indonesia as much as 13 submarines. With the percentage of each strategic submarines: 23% Makassar Strait (3 Submarines), the Lombok Strait 15.4% (2 Submarines), Strait of Halmahera 30.77% (4 Submarines), Wetar Strait 15.4% (2 Submarines), Strait Ombai 15.4% (2 Submarines). If there is a dynamic field that can easily be placed in the strait Submarines received threats in accordance with the percentage division. Suppose a threat occurs only in Hot Area I (Makassar Strait and the Strait of Lombok) then placed Submarines strength at 35.4% (5 Submarines).Keywords: Submarine, Probability Concepts, Determination of Total submarine

DECISION SELECTION MODEL OF LANDING BEACH IN AMPHIBIOUS OPERATIONS EXCERCISE WITH FUZZY MCDM Agus Setiadji; Benny Sukandari; Joni Widjayanto; Rifki Najib

To determine the ideal landing beaches in amphibious operations must meet the requirements / criteria that have been determined, because it serves as an important component in the choice of landing beaches. The criteria include the type of beach, gradient beach, the basic material of beach, long beach landings, the type of breaking waves, tide, the kind of obstacles beach, ocean currents, the field behind the beach, the reference point mark landing beaches and access to the exit / entrance beach , In determining the selection of the landing beaches Marine / Navy had not done the calculation / mathematical model and not using a scientific method, such instances it is necessary to make a decision-making model in the case of election of the landing beaches in amphibious operations exercise. This study aims to determine the location of the landing beachesusing Fuzzy MCDM. The use of this method is the solution to produce a more objective group decision in the selection of an amphibious landing beach which data are accurate and reliable to help solve problems that are multi-criteria. There are 11 (eleven) criteria and 4 (four) alternatives identified in this study. Of the 11 criteria which have the highest weighting criteria for the alternative chosen in the first rank third alternative, namely PPD 3. Keywords: Amphibious Operations, Fuzzy MCDM, Criteria and Alternatives.
