The territorial waters of Riau Islands are one of the locations with a high level of vulnerability to violations in thesea in Indonesia, because this region is directly adjacent to neighboring countries and is an international tradeand shipping route. One of the roles of the Indonesian Navy is to maintain the security of national jurisdictions,including in the territorial waters of Riau Islands, which are then realized in Operation Sea Security, where theimplementation still has several constraints, namely budget constraints, technical capabilities, number of ships,limited information, and limitations supporting facilities, so that the implementation of Marine SecurityOperations is not optimal. The main reason is the placement of patrol boats during operations is not wellorganized. With these problems, a study was conducted using the set covering method to get the most optimallocation for patrol boat placement with as few ships as possible but still be able to reach the entire waters of theRiau Islands and minimize operational costs. In this study a discrete approach was taken, namely thedetermination of the critical points, which numbered 37 vulnerable points. All these points must be affordable bythe ship on duty.Keywords: Set Covering, Location Selection, Marine Security Operations, Riau Islands Waters Region

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.

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.

Scheduling is an assignment activity that deals with constraints. A number of events can occur in a period of time and location so that objective functions as close as possible can be fulfilled. In the hierarchy of decision making, scheduling is the last step before the start of an operation. Scheduling warship assignments in Kolinlamil are an interesting topic to discuss and find solutions to using mathematical methods. The process of the Kolinlamil warship assignment schedule was carried out to produce an annual shipbuilding schedule. This process not only requires fast follow-up, but also requires systematic and rigorous steps. Where the assignment schedule is a fairly complex combinatorial problem. While making the assignment schedule that is applied at this time is considered less accurate because it calculates the conventional method. The process of warship assignment schedule in this study using the Integer Programming model aims to obtain alternative scheduling operations. The schedule observed was 13 warships in carrying out N operations for 1 year (52 weeks). This research begins with determining the decision variables and limitations that existing constraints. Hard constraints include: maintenance schedule, time and duration of each task, warship class assigned to the task and the number of executing warships per task. While soft constraints are how long the warship performs its tasks in a row. The mathematical formulation of the Integer Programming model created consists of three indicator, one decision variables, two measuring parameters and five constraint functions. Furthermore, determining the best scheduling alternatives is completed using the Microsoft Exel Solver computing program.Keywords: Scheduling, Integer Programming, Solver.
