Abstract

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

Abstract

The function and role of the Strategic Sealift Vessel (SSV) ship type is very important. Modifications andchanges to improve the value of efficiency will be very necessary. This efficiency value is closely related to thevalue of Ship Resistance , where if the Resistance value goes down, the value of the ship's efficiency will rise.The increase in efficiency is then expected to reduce fuel consumption and increase speed. In several studies,ways have been improved to improve the condition, one of them is by adding a Dimple to the Surface Area ofthe ship, this modification will reduce the friction Resistance that the ship will receive by reducing the WettedSurface Area that the fluid will pass at certain speeds and conditions. . This modification will be applied to theship's Bulbous Bow section. In this way it is expected to improve the value of the Resistance produced by theBulbous Bow installed in the ship, without having to carry out significant changes or modifications and changethe shipbuilding of the existing Linesplane. Furthermore, the analysis is carried out by modeling using 2D and3D CAD Software and Model Experiments using CFD Applications. After carrying out the entire process ofRunning with the CFD Software to determine the value of the Ship Resistance . The final conclusion is in theform a reduction the value of vessel Total Resistance the Running Bow section of 31.53% in the 4th variationsand Fn used is 0,341.Keywords: Boulbous Bow, CFD, Dimple, Reduction, Resistance

Abstract

Branta Port, located in Pamekasan Madura, is a connecting port area around Java Island and Madura Island. The port has an important role in logistics and supply chain activities as well as economic development in Indonesia, especially in Java and Madura. But the reality is Branta Port has some shortcomings in the port facilities to security sector. It based on the lack of regulation enforcement of the port management itself. The lack of renewal of the port master plan is also one of the obstacles to the port's poor performance. Therefore, with this research, it is expected to obtain a broad picture of the development strategy at the Branta Port. The methods are Location Quotient (LQ) & ships loading and discharge at port forecast using several forecasting analysis. The results show the ships call, loading and discharge flow at Branta Port have a fluctuating pattern follow the seasonal trends in salt production activities in Madura region. Where in 2039 (long-term) the loading and discharge flow at Branta Port is predicted to reach 380,927 tons which in 2018 amounted to 139,855 tons. The results of the port performance calculation are performed using port performance indicators called Berth Occupancy Ratio (BOR), where the BOR value from year to year to the long-term forecasting year (2039) is 22.08%, which is still below 40% for an additional indicates that the jetty is not busy according to UNCTAD criteria. Whereas the need for port facilities such as warehouses and stacking fields has increased. The development strategy focused on port facilities such as the berth length expansion from 100m to 186m, construction of port warehouses of 183m2, improvement of several port facilities such as navigation facilities and causeways, also the addition of port waste treatment facilities.Keywords: Location Quotient, forecasting, econometric method, Berth Occupancy Ratio

Abstract

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

Abstract

Faced with conditions of life of the nation that continues to evolve into a multidimensional cover all areas of lifeof the nation, then certainly required the development and deployment of the total potential and power of thenation effectively. Therefore it is the power that was developed to deal with these threats must also have theability to multi-dimensional as well. Reality is always pushing to restructure the military concept of defense tobecome responsive and adaptable and tailored to the substance of the reforms in the defense. The mainproblem faced by Indonesia to develop a domestic defense industry is the inability of industry and educationsectors to absorb the fundamental aspects of the Revolution in Military Affairs (RMA). This inability does notallow Indonesia to experience significant breakthroughs in the application of RMA. So with reference to thecondition necessary to anticipate concrete steps in developing a systematic plan to build the defense industriesare able to anticipate the revolution in military affairs. Among priorities at once by selecting the appropriatestages of the development plan which includes the development of Main Equipment Weapon System, SpatialPlanning Area Defense, Civil Defense Development, and Spatial Structure of the Organization. And one of itsefforts is the creation of the ability of military logistics support system effective and efficient and responsive,which in this case is the development of Arsenal's arsenal of weapons and ammunition in terms of both qualityand quantity so that is always ready to face any condition of any contingency that would happen. Determiningpolicy location Arsenal first location contains more choices in environmental issues multiobjectiv andmulticriteria decision, then the model is proposed to be the appropriate methodology to accommodate thequalitative preference and priority-setting objectives / criteria for future development is to approach theAnalytical Hierarchy Process (AHP). Principle of the AHP method is to break breaking a complex situation andunstructured, into its component parts, arranging these variables in a section or an order of hierarchy, givingnumerical values to subjective considerations about the relative importance of each variable and analysisvarious considerations is to determine which variables have highest priority and act to influence the outcome ofthe situation. From the results of the solution by using AHP method showed that the first priority locationdetermination Arsenal 1 in the eastern region is a factor analysis of logistics operations to support operationscapabilities in integrated logistics support system that effectively and efficiently. And the locations selected forArsenal's first priority location is in the eastern region Lantamal Ambon. Keyword: Determining location - Approach of the Analytical Hierarchy Process (AHP)

In its2017 procurement, the Navy made a second generation Fast Ship Missile (KCR) made by PT PAL thatproduced more than the previous generation, both in terms of capacity and rich ships, named KRI KerambitClass. To support the battle, this KRI Kerambit Class will be equipped with a surface to surface missile (SSM) toimprove the ability to use maximum battleships. To be able to activate its function properly, it is necessary tochoose the right missile base weapon. The selection of alternative missile weapons over water requires analysisof information and collects important requirements about data from alternative weapons over the air. In additionto alternatives, it is expected that major criteria will be considered in the selection of the Weapons over the air.In making the decision to procure Weapons Over Water, where the conflict cannot be arranged in the form of ahierarchy because it requires interaction and higher level elements to lower level elements. Therefore in thisstudy the Trial Making and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP) methodshave the ability to accommodate the interrelations between criteria or alternatives. Based on data processing,the Exocet MM 40 Block 3 has been selected. This missile has several advantages compared to other missiles,including launching at counters and missfire that is very low and has very good durability.Keywords: Missile Selection, DEMATEL, Analytic Network Process
