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)

Abstract

Maintenance management is required and has a very vital role for a KRI types FPB57, considering the type KRI is one Alutsista Navy who have a high frequency activity, as well as the broad range of operations support capabilities are varied so that the automatic machine is also high activity and in the end reliability will decrease. Methodology Failure Mode Effects and Criticality Analysis (FMECA) is a widely recognized tool for the study and analysis of the reliability of the design or process. Many authors in the field have emphasized specifically the usefulness of this method and its limitations. At this writing considering the lifetime of the machine and the elements therein specifically the components of the water coolant pump has had a lifetime of more than 20 years, because it can be said that the components have entered a critical period. Based on the steps Failure Mode Effects and Criticality Analysis (FMECA) through the calculation of Risk Priority Number (RPN), so we can determine the critical components of acquired 9 19 chances damage that has critical component is Angular Bearings, Cylindrical Bearings, Spacer Ring, Water Seal, shaft Seal, Seal Slip Ring, Impeller, O'Ring and shaft. These components if damaged can lead to engine breakdown. Of the optimization results indicate that the component replacement Cylindrical Bearings have the fastest time, ie 98 days. While the replacement of components with the longest time, which is a component Impeller 134 days. Besides obtain the most optimal replacement time of each component, also produced the cost of replacement is effective, it is proved by the value of the optimal CBR CBR value for all types of components is less than 1 (CBR <1).

Abstract

Indonesia as archipelagic country, needs strong maritime sector security. The Indonesian Navy in Law Number 34 Year 2004 has been given the mandate to safeguard the sovereignty of the Republic of Indonesia. The Armada II Command as Kotamaops annually carries out Military Operations Other Than War (OMSP) which is carried out under the command of Guspurla and Guskamla. Intelligence information regarding the estimated threat / contingency that will occur is very influential on decision makers in operational planning. With the contingency provided by the intelligence staff, it is necessary to have an appropriate marine operation modeling. In a multi-operation operation, it is necessary to have a supporting attribute, that is, a base ship. The purpose of this study is to formulate an operation modeling using the selection of a headquarter ship which is preceded by the determination of contingency priorities. This study uses MCDM which consists of MCDA and MCDO which uses the integration of the Delphi method, AHP, Fuzzy weighting, Goal programming and linear Integer-Zero one programming. Based on the processing of Delphi and AHP, in determining the threat of OMSP, it is influenced by the number / intensity of incidents of 20.4%; impact of Ipoleksosbudhankam 29.4%, Capabiity 38.2% and involvement factor of 12.1% where national jurisdiction marine security operations are selected as the first priority. Meanwhile, in the selection of the headquarters ship which functions to coordinate the KRI in carrying out sector patrols, using the FWH and IGP, the KRI was chosen as the Sigma class to be the headquarters ship. This modeling uses 22 of the 24 KRI that have been allocated by obtaining an increase in the optimization of the coverage area and fuel savings..

Abstract

In carrying out increasingly complex tasks, and the development of naval technology, Fasharkan requires personnel who are professional in their fields and supported by technology-laden equipment in accordance with the development of the Indonesian Navy's defense equipment system. The purpose of this research is to determine an alternative strategy to increase the capability of Fasharkan Surabaya where Fasharkan Surabaya has a very strategic location because it is located in the Koarmada II environment which is the Home Base of the KRI which will carry out operations or finish operations. This study uses the integration of SWOT analysis and ISM (Interpretative Structural Modeling). SWOT analysis is used to formulate and provide alternatives in the strategy to increase the ability of Fasharkan Surabaya, while ISM is used to determine the order of priority for the selected strategy. Based on the results of the SWOT matrix analysis and weighting using the IFAS and EFAS matrices, the chosen strategy is the WO Strategy which consists of 9 (Nine) strategic steps, so the WO strategy is the first alternative. Furthermore, at the stage of classifying the elements in the WO strategy, the ISM method is used and from the results of the MICMAC analysis, it is found that there are 5 (five) levels of the hierarchical structure. In the hierarchical structure, it can be seen that the sub-strategy (WO2) is at level V, level IV sub-strategy (WO1) (WO3) and (WO7), level III sub-strategy (WO4) and (WO8), level II sub-strategy (WO6) and (WO9) and level I sub-strategy (WO5).

Abstract

Indonesia is on the International Sea Lanes of Communication (SLOC) and Sea Lines on Trade (SLOT) shipping lanes. Indonesia's geographical position provides advantages and disadvantages, namely threats to Indonesia's sovereignty and security. Indonesia's strategy to maintain sovereignty at sea is guided by the Archipelago Sea Defense Strategy (SPLN). The SPLN is an operational guideline for the Navy to carry out its main tasks, namely preventing interference with sovereignty and overcoming threats to the sovereignty and territorial integrity of Indonesia. The Republic of Indonesia Fleet Command Organization underwent organizational validation into three fleet commands. The addition of fleet command requires the addition of warships, including submarines. This study aims to formulate the right strategy in the pattern of submarine operations throughout the fleet command. This study carried out data analysis using Analysis of Strengths Weakness Opportunities and Threats (SWOT) combined with the Analytical Hierarchy Process (AHP). The result of the research is that the submarine units in the Fleet II Command Submarine Unit have a strength factor, namely modern submarine units and modern submarines have good combat capabilities. The weakness factor is that Indonesia has not yet operated tender vessels and Search and Rescue vessels. Another weakness is that the location of the submarine base is only in Surabaya. The opportunity factor used is the opportunity to develop a new organization under the Fleet Command. And the threat factor is the pattern of the Navy's title which still focuses on maritime security operations using surface warships as the main means. The new organization will serve as a submarine operations commando under the command of the fleet. This organization will embody the pattern of future submarine operations titles. Keywords: SWOT, AHP, Submarine, Operation, Organization Validation.

Abstract

ABSTRACT Maintaining stability of the National jurisdiction security, particularly in the Indonesian eastern waters is one of the roles of Indonesian Navy which is implemented in the Maritime Security Opeation (MSO) by assigning Navy Patrol Ships (PC). In terms of capabilities and the number of Indonesian PC compared to the extensive area of the MSO sector, it still considered to be not optimal, so the Navy need to think and perform right calculations in the assignment of PC and choose Navy Bases as the initial position of MSO by PC. This study aims to create a set covering model in calculating the assignment of patrol ships to create a set covering model to calculate the assignment of patrol ships optimally by minimizing assigned patrol ships number however can still cover all patrol sectors. This model also used the Analytic Network Process (ANP) approach to select the Naval base as the initial base for patrol ships in implementing MSO. Optimization results were to assign 12 patrol ships which could cover 18 patrol ships and 3 Naval bases from 9 bases that can be used as an initial base for PC in the implementation MSO.

Abstract

The workload of an organization is related to the efficient and effective utilization of human resources so that it can realize the vision, mission and objectives of the organization. Various methods are used to optimize the number of personnel in an organization, so that each task can be completed effectively and efficiently. KRI Diponegoro-365 personnel as the TNI Maritime Task Force, the Garuda Contingent can not be separated from the problems regarding the lack of conformity to workload with the allocation of the number of available personnel. To overcome this, an analysis of workload measurement is needed which can then be used for determine the allocation of the right number of personnel needed in each division. This study uses the measurement of NASA-TLX mental workload and physical workload according to TNI Roles. Both of these methods are then compared between mental and physical burden that occurs. From the results of the comparison, it was found that physical workload is needed in the completion of tasks in each division. After a comparison, then the determination of the allocation of the number of personnel will be carried out using the physical workload approach based on the description of the tasks in each division. The results of the calculation will then show the division that has excess or lack of personnel. The overall results obtained from this study can be concluded that the number of maritime task force personnel using the Diponegoro class KRI is appropriate, but the allocation of personnel in each division needs to adjust to the existing workload. Keywords: Workload, NASA-TLX (Task Load Index), Number of Military Personnel
