Abstract

The level open unemployment is a value that shows the number of working-age population who looking for work, is preparing a business, feels impossible to get a job or already have a job but have not started working and often used for measured employment. Like at Central Java has increasing the total population at 2014 and have high total investation whereas should be can getting more employment, but actually still give high unemployment about 996.344 population at 2014. So that, in this research used nonparametric regression approach which multivariate adaptive regression splines (MARS) for modeling the level open unemployment in Central Java at 2014 because the level open unemployment in Central Java predicted influence by some factors. This research resulted in the best modeling for level of open unemployment in Central Java Province with value of GCV minimum that obtained at 0,396 with R-square at 86,5 percent as well as the predictor variables were entered into the model as much as three, namely the total population with interest rate of 100 percent, the minimum wage with interest rate of 41,955 percent, and the total working population with interest rate of 39,547 percent. Keywords: MARS, Nonparametric regression, Level of open unemployment

Abstract

ABSTRACT Lapetal is an organization within the Indonesian Navy that is tasked with carrying out Navy recruitment. With the increasing number of duties and responsibilities of Lapetal and seeing the current condition of Lapetal, it is necessary to make efforts to develop Lapetal in the future. The purpose of this research is to identify the factors that influence in determining the Lapetal development strategy, determine the alternative strategy for Lapetal development, and produce a roadmap of the selected alternative strategies for Lapetal development. This study uses an integrated SWOT analysis and Interpretative Structural Modeling. SWOT analysis is used to formulate and provide alternatives in Lapetal development strategies. ISM is used to determine the priority order of the selected strategy which is then applied in making the roadmap. Based on the results of the SWOT matrix analysis, the SO Strategy consists of 6 (six) strategic steps, the ST Strategy consists of 5 (five) strategic steps, the WO Strategy consists of 8 (eight) strategic steps and the WT strategy consists of 4 (four) strategic steps. Based on weighting using the EFAS and IFAS matrices, the chosen strategy is the WO Strategy, so that the WO strategy becomes the first alternative. Based on the results of the classification of elements in the WO strategy, there are 4 (four) levels of hierarchical structure. In this hierarchical structure, it can be seen that the (WO5) and (WO6) sub-strategies are at level IV. Then the sub strategies (WO3) and (WO4) are at level III. At level II it consists of 3 (three) sub strategies, namely (WO1), (WO2), and (WO7). At level I, it is the sub strategy (WO8). The output of the SWOT and ISM analysis process in determining the Lapetal development strategy is a map or roadmap implemented in a strategic plan which is divided into five-year programs. Keywords: Lapetal, Development Strategy, SWOT, ISM, Road map

Abstract

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).

Abstract

This thesis describes the application of the Fuzzy Analytical Hierarchy Process (Fuzzy AHP) approach and Benefit Cost Ratio (BCR) analysis in submarine selection. Submarines as Main Defenses System which are highly strategic in their procurement are directed at realizing a deterrence strategy and a strategy of balancing with state actors that have the potential to threaten the sovereignty of the Indonesian state. Apart from threats, the procurement of submarines also considers Indonesia's geographic constellation and the government's wishes, such as the interest of the minister of defense during working visits to countries that offer their submarines. The first step in procurement is to make an analysis in terms of selecting submarine alternatives, both analysis of information and identification of various important and interrelated requirements regarding data from submarine alternatives that will be selected later. Uncertainty from the government is a fuzzy'nes decision, so this condition can be resolved with the Fuzzy AHP approach and strengthened by BCR analysis, so that the results can provide a higher contribution. The results obtained from the Fuzzy AHP method are the priority order of selecting alternative submarines, namely Y-Class (0.398), W-Class (0.220), X-Class (0.191) and Z-Class (0.191). Where the results of the importance of the main criteria are sequential starting from the Strategic Requirement (Strareq) criteria of 0.409, Operation Requirement (Opsreq) of 0.318 and Technical Requirement (Techreq) of 0.273. Meanwhile, based on the BCR analysis, the Y-Class submarine was also selected with a BCR value of 1.512232936. Keywords: Fuzzy AHP method, BCR Analysis, Submarine Selection.

Abstract

A project of base facility is a kind of routine developing in Indonesian Naval. In this developmentt is necessary to develop methods in measuring performance and evaluating project time through a more accurate critical path feature. The research problem statement is how to evaluate the project schedule related to the time and cost of the Indonesian Navy's facility construction project by conducting a case study as a study for project scheduling at a later stage. The research objective is to identify the critical path of the project through network analysis, determine the factors that cause delays and how to overcome them, and calculate the time effectiveness and cost-efficiency of the project based on the calculation of scheduling acceleration. In this study, project performance measurement was carried out using the Earned Value Method (EVM) and network analysis using the Precedence Diagram Method (PDM). The solution to overcome delays with the crashing project method. The results of the discussion identified 15 critical path activities. The factor causing the delay is the delay in activities on the critical path due to the low level of productivity of the workforce group. The crashing method through additional 2 hours/day overtime can solve the problem of delays so that project implementation can be accelerated from the implementation of 256 working days to 226 working days (11.72% effectiveness) with the initial project cost of Rp. 74,316,727,585.00 reduced to Rp. 72,152,162,704.00 (2.91% efficiency).

Abstract

Some of the Indonesian naval effort to see and protect the Indonesian territory is by using Helicopter sea patrol. In the other side, submarines are the most strategic weapons in the world that can provide a deterrence effect which has a very significant impact on the maritime powers of the countries operating them in the era of generation 4.0 war. Operational readiness is very important, there are readiness in building operational readiness for naval defense through budget fulfillment, utilization of existing resources, procurement and naval modernization by paying attention to Life Cycle Cost, and interoperability while still paying attention to paradigm shifts in naval capability. So, the combat readiness is the condition of the Indonesian Navy's defense equipment and its constituent units, resources and personnel, weapon systems and other military technology equipment in a condition that is ready to carry out military operations in an unspecified time, or function consistent with the purpose for which the defense equipment is organized or designed, the management of resources and training personnel in preparation for combat in the face of the threat of modern warfare in a state of constant combat readiness. At this time, training in Anti-Submarine Warfare conducted by Indonesian Navy’s Helicopter is still limited to carrying out flight procedures, communication procedures with the KRI and the command line, because Helicopters have sensors, weapons and command that need to be upgraded and The personnel also have underwater warfare capabilities that need to be upgraded, so there needs to be an increase in the capability of the helicopter and human resources. Technometry will be used to calculate the Heli's current readiness level. Keywords: Submarine, Anti Submarine Helicopter and operational readiness
