The Sea Mines are explosive devices placed in the waters to destroy ships or submarines. The sea mines were placed in the water depths and waited until it was triggered to be blown up by an approaching enemy vessel. The waves in the leave can be measured using the air pressure sensor placed below the water surface, the change in the sensor up and down will result in changes in air pressure. Changes in the resulting pressure of the vessel will result in water waves, resulting from changes in the water wave height will result in a change in water pressure gauge sensors in the air. The MPX5700 air pressure Sensor, as a source of pressure measurement with analog voltage output is comparable to the large value of air pressure. Design the air pressure measuring instrument system using the Arduino microcontroller as the unit of the voltage conversion process to the pressure variable in the KPA. On testing authors use applications that are created using Visual Studio 2012 to plotting the pressure graphs and large voltage output sensors. Results obtained using the MPX5700 sensor with an analog output can result in a linear pressure output with a large voltage output, from the test result obtained the conversion value 0.2 V as the value of 0 Kpa and the value of 4.7 V asthe maximum value pressure measurement of 700 Kpa. Keywords: mines, MPX5700, Arduino microcontrollers

KRI Halasan - 630 is one of the Fast Missile warships with a length of 60 Meters which apart of fast patrol boat class which belongs to TNI-AL. Accordance with the main function not only as a fast missile boat but also as a patrol ship killer, this ship was made to have a high ability in “hit and run”. Since the beginning of the manufacture and after being inaugurated as KRI in 2014 this ship is able to reach speed until 27 knot in full load. As time goes on the same conditions the speed that this ship can achieve is 25 knot at maximum speed. This can be caused by increase in value from the resistance of the ship. One way to reduce the value of the resistance of the ship is to minimize the Wet Surface Area(WSA) from the ship. By adding hydrofoil technology will produce lift force which could lift apart of the hull ship from the water so that Wet Surface Area from the ship will reduce. From the calculation, to lift on the hull of KRI Halasan Class 20 cm in full load condition at 25 knot knows that dimension for fore foil with tapered straight type are wingspan 4,6 m, wingroot 1,33 m, wingtip 0,5 m, and swept angle 11°. And dimension for aft foil with rectangular straight type are wingspan 5,3 m, wingroot and wingtip 1,365 m, and swept angle 0°. The ship resistance with hydrofoil is 265,5 KN, while in the same condition and speed from the ship without hydrofoil the value of ship resistance is 267 KN. By adding hydrofoil technology could reduce the ship resistance 1,5 KN. This values could make 19,29 KW or 25,86 Hp in power saving.Keywords : Hydrofoil technology, Ship Resistance, Halasan Class

Republic of Indonesia warship is one of the main elements in the Integrated Fleet Weapon System (SSAT) owned by the Indonesian Navy. Republic of Indonesia warship must have combat readiness so that it is always ready to carry out exercises and operations according to its main tasks. Combat readiness can be achieved thanks to good logistical support. The codification information system is an important part of the automation of debriefing at Dopusbektim in providing computerized logistical support. With the codification information system, it is hoped that the user unit will be easier and can shorten the processing time of requests at the depot warehouse. The research objective is the development of existing applications by designing a codified information system application using the Quality Function Deployment (QFD) and System Development Life Cycle (SDLC) methods, so that it is expected to solve existing problems. Through interviews and questionnaires obtained 12 attributes. The 12 selected attributes above are then processed using the Quality Function Deployment (QFD) method in the House of Quality (HOQ) matrix so that the highest technical importance value is obtained, namely the integrated technical response with the Codification Subdistribution with a value of 367.7. This technical response is integrated with the Codification Subdistribution which is used as the basis for developing new application designs according to the stages in the SDLC method. The final result of this research is a new codification application system that is integrated with applications in the KRI and applications in the Codification Sub-Office so that it is expected to facilitate input of request data from ships and can shorten the time for requests to receive (PUT) in the provision support process.

Uncertain global dynamics is one of the main factors influencing the successful achievement of goals and interests in the field of national defense. This reflects how important it is for stakeholders in the defense sector, to understand the dynamics of the strategic environment which presents a series of opportunities, obstacles to threats to the existence of the Republic of Indonesia, which in the end will obtain strategic steps to overcome them. The Indonesian Navy is strongly influenced by several components, such as the strength structure, the level of readiness, the level of sophistication or technological sophistication and the operational durability of its Alutsista. The synergy of the four components of strength is very much determined by the country's ability to build and maintain the ability of the defense equipment. Currently, Arsenal does not have a regional warehouse and there is only one central warehouse in Surabaya. The wide working area of Koarmada II, of course, requires a large number of KRI elements. Arsenal really need regional warehouses in order to be able to increase KRI's operational support in the Koarmada II working area. This is necessary considering that the operation at sea requires a very high presence of KRI. So that if there is a need for ammunition supplies, the process of supplying them can be carried out quickly. This research uses the Fuzzy Multi Criteria Decision Making (FMCDM) method. Overall, the results obtained from this study, it can be concluded that the best location from the alternative location is in the Koarmada II area, namely Lantamal Manado with the highest value of 0. Keywords: Determination of Location, Fuzzy Multi Criteria Decision Making (FMCDM).
