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).

The process of designing a propeller as a ship propulsor is an important step to produce a propeller that has the ability to achieve the desired target speed of the ship. Propeller optimization is an effort to produce a propeller design with optimal capabilities. This propeller design uses a B-series propeller where this propeller is commonly used as ship propulsor. Optimization steps to find the optimal propeller, namely: determining the objective function, determining the decision variable, and determining the constraint variable. The objective function of this optimization is to determine the Advanced-optimal (J-opt) coefficient value for the propeller. The J-opt coefficient must have a value greater than the J-Design coefficient (J-d) value and the smallest possible value (minimization function). For decision variables include picth diameter ratio (P / D) and Blade area ratio (Ae / Ao) and number of leaves (Z). While the constraint variables are: the pitch diameter ratio value of the B-series propeller (0.5≤P/D≤1.4), the blade area ratio B-series (0.3≤Ae/Ao≤1, 05) as well as the number of blade (2≤Z≤7). From the calculation results of the optimization of the B-series propeller design for the KCR 60, the optimum value is different for each blade. the propeller with the number of blade 2 (Z = 2) obtained the optimum propeller with the value of J-opt =0.77098733, Ae/Ao=0.3, P/D=1.13162337, KT = 0.165632781, 10KQ=0, 27546033 and efficiency=0.73198988. Popeller with number of blades 3 (Z=3) obtained optimum propeller with J-opt value=0.77755594, Ae/Ao=0.3, P/D=1.06370107, KT=0.168069763, 10KQ=0.28984068 and efficiency=0.70590799. Propeller with number of blades 4 (Z=4) obtained optimum propeller with J-opt value=0.78478688, Ae/Ao=0.45954773, P/D=1.03798312, Kt=0.172147709, 10Kq= 0.3091063 and efficiency=0.67797119. Propeller with blades number 5(Z=5) obtained optimum propeller with J-opt value=0.78575616, Ae/Ao=0.65607164, P/D=1.02716571, KT=0.174099168, 10KQ=0.31376705 and efficiency=0.67547177.

The shipping industry sub-sector, although contributing quite significantly to Indonesia's economic growth, has not yet included leading commodities in industrial development in Indonesia. The problem that must be examined in the effort to develop the shipping industry is the absence of the determination / application of the right strategy to be able to maximize the potential of the existing potential that enables the shipping industry to become a competitive industry. The research is carried out with the following stages: - Searching for sources of information that can provide an overview of the boundaries, subject matter of the study, developments and problems in the shipping sub sector, territorial understanding, understanding of management strategies, to then set the goal formulation as the direction of conducting research. - Conducting an expert survey to review and determine the elements / sub elements related to the development strategy of the shipping industry real sector of the shipping industry. - Designing a structuring system by conducting studies / determination of the key elements of development, with Interpretative Structural Modeling (ISM). Based on the results of expert studies, 4 elements and 12 sub elements were determined that have strong interactions with the development of the shipping industry in Indonesia. The elements are then analyzed by the level of interaction with the ISM-VAXO technique. The first step is to study the contextual relationship in the form of the SSIM-VAXO Matrix. This method has been able to classify all sub-elements into four quadrants based on the value of Drive Power and Dependence and in the hierarchical structure based on Ranking and Level, which then informs the key sub-elements of the development of the shipping industry, namely: sub-elements: Provision of human resources with shipping knowledge and skills adequate (7) and sub-elements Improvement of managerial skills training program (8).Keywords: Shipping industry, development strategy, ISM

ABSTRACT Quality human resources who are in the Indonesian Navy organization have a very important role. Because with the Indonesian Naval Main Weapon System (Alutsista) award, which is getting more and more sophisticated and the challenges in the era of the industrial revolution 4.0, it is hoped that its human resources will be able to reliably manage the defense equipment. In looking for quality human resources, good planning is needed to achieve optimal organizational goals in the utilization of existing resources. The provision of quality human resources in the Indonesian Navy requires a qualified organization, in this case, is carried out by the Lapetal. So that we need a strategy to develop the Indonesian Naval Human Resources unit. The purpose of this study was to obtain the factors, criteria, and formulation of development strategies. This study uses the SWOT analysis method. Based on the SWOT analysis, there were 10 criteria for internal factors and 7 criteria for external factors as well as 4 alternative strategies, namely 7 SO strategy steps, 5 ST strategy steps, 6 WO strategy steps and 4 WT strategy steps, WO strategy was chosen as the first alternative with the highest weight of 4, 01. Keywords: The Indonesian Naval Human Resources Unit (Lapetal), SWOT Analysis.
