Abstract

Presently, the rapidly increasing population growth has been shown to create the growing needs of sea transportation services, both for freight and passengers. The augmentation of sea transportation fleets causes the ever-increasing number of all types of ships and the vessel traffic congestion in many connected sailing lanes. The development of sea transportation media significantly affects the potency of sea pollution. Therefore, it requires an analysis of the development feasibility of the Reception Facility in Tanjung Perak Port Surabaya. The first analysis is by doing the evaluation of investment feasibility based on the law, market, technical and financial aspects. After that, the measurement is done by using the methods of Net Present Value (NPV), Payback Period (PP), Internal Rate of Return (IRR), Average Rate of Return (ARR), Profitability Index (PI) and investment risk analysis. In this research, the gained NPV is about Rp. 431.257.167, PP value about 8 years 9 months 26 days, IRR 22,695%, ARR 30,32%, PI about 1,39, so the infrastructure investment program of Reception Facility in Tanjung Perak Port Surabaya is feasible to be carried out.

Abstract

The FMEA method is a tool used to identify the consequences or consequences of a system or process failure and reduce or eliminate failure. In determining risk factors and system improvement priorities, traditional FMEA still has weaknesses, where FMEA traditionally places severity factors, occurrence, and detection at the same level of importance, even though in reality different levels of importance and the importance of FMEA assessment teams are ignored. In this study, the fuzzy method is integrated into FMEA where the severity factor, occurrence, and detection are assessed in linguistic form. In this fuzzy method, the weight of the interests of the FMEA assessment team is taken into account to do ranking and repair priorities. The application of Fuzzy methods to FMEA to determine significant risk factors and prioritizing improvements from various alternatives chosen for the process of repairing KRI in Surabaya Lantamal V, so that it is expected that the application of this method can improve the operational performance of Fasharkan to eliminate or reduce the risks that occur in the repair process ships in the eastern region of the fleet.

Abstract

ABSTRACT Unmanned submarine commonly called Autonomous Underwater Vehicle (AUV) is one type of underwater robots used for underwater mapping. AUV is an underwater vehicle capable of automatically moving in water, controlled by humans on vessel. To build AUV is not easy as many components play important roles in the operation of AUV, one of which is active ballast. Calculations on the making and benchmarks of active ballast systems are still very rare. Active ballast is a set of equipment used to fill its tanks with seawater and to empty sea water from the tanks on submarines. These tanks are intended to balance submarines and for active ballast systems on submarines so as to be able to dive and float as needed. In this paper an experimental study was carried out on a tube resembling AUV with both fresh water and sea water to obtain ballast volume in AUV. Keywords: AUV, Active ballast, Experimental study

Abstract

The workload is highly related to efficient and effective human resource utilization in an organization to achieve organizational objectives, vision, and mission. Various methods are used to optimize the number of personnel in an organization so that each task can be completed quickly and precisely. Accounting Institutions are inseparable from problems regarding the lack of workload with the number of personnel working on it. The change of the Policy gives an impact on the change of Job Description and List of Personnel Arrangements of the organization. To overcome these issues, workload measurement, analysis can be used to determine the optimal amount of personnel required in their working units. This study uses a mental workload measurement so called NASA-TLX and physical workload measurement According to the applicable workload regulation that is in accordance with the Administrative Direction of Workload Analysis. Both methods are then carried out to be compared to each other. The results showed that the physical workload is required in the completion of tasks in each work unit. In addition, the determination of the optimal number of personnel using physical workload or appropriate tasks per task position based Job Description is performed. As a result, it is known that there is an excessive workload in the Sub Service Budget Cost work units with personal shortcomings. On the other hand, there is an excessive personnel number in Administrative Work, Sub Department of Finance Administration and Sub Department Financial Control. The overall conclusion of this study is a need for personnel reduction in a List of Personnel Arrangements currently known as Accounting Institutions to be 39 personnel instead of the existing 48 personnel.

Abstract

The scheduling of production floor is a sophisticated problem which seeks the optimal task allocation to certain resources under a number of constraints. The use of optimization techniques facilitates the determination of acceptable solutions that considered optimized for a specific problem. This paper proposes production scheduling solution based on job priority in a Non-Deterministic Polynomial-time hard (NP-hard) problem. The case study was taken from the Spirit Aerosystem Project, particularly in the Inboard Outer Fixed Leading Egde - Drive Rib 1 component production process. The problem consists of finding the machine operations schedule, taking into account the precedence constraints. The main objective is to minimize total delays or tardiness. The genetic algorithm was employed to determine the optimized production scheduling solution. The parameter for genetic operators in this study consists of a roulette wheel selection, 1 elitist chromosome, partially-mapped crossover mutation and 1 point mutation. The termination condition was achieved when there has been no improvement in the population for 30 iterations.The results show that the algorithm is capable to generate optimum production schedule with minimum tardiness for the given problem.

Abstract

ABSTRACT Sonic Layer Depth is the vertical distance from surface to the depth where the speed of sound reach it’s local maximum. Global Navy as well as Indonesan Navy operates in this kind of layers on a daily basis, wether it be in an anti submarine warfare operation through its ships and aircrafts or in an anti-surface warfare operation waged by its submarines. For the navy, the importance of knowing the exact value of the SLD is because it determines the minimum cut off frequency and sound wave propagation above which sound tends to be trapped and below which a shadow zone exist. This has a direct impact on where the navy operates its sensors and places its platforms in the water column. The best way to estimate SLD is by performing own measurement on the ocean using instrument such as expendable bathytermographs, which can be relatively expensive and time consuming for an operational navy ships, furthermore such measurement may be impractical in the case of mission planning or emergencies. Dedicated oceanography survey for the purpose of science and defense is relatively scarce due to prioritization concerning to the budget available resulting lack of time series in situ CTD observation which cover full annual cycle variation in Indonesia waters. Banda Indonesia Through Flow Dynamic Experiment (BIDE) is multi institution and bilateral oceanography experiment led by Indonesian scientist which utilizes argo float to perform in situ CTD measurement in Banda Sea to get an adequate time series data that cover full annual cycle variation. The dataset is publicly available so defense community as well may utilize the data for defense interest such as sonic layer depth variation analysis in Banda Sea.

Abstract

Faced with conditions of life of the nation that continues to evolve into a multidimensional cover all areas of the life of the nation, then certainly required the development and deployment of the total potential and power of the nation effectively. Therefore it is the power that was developed to deal with these threats must also have the ability to multi-dimensional as well. Reality is always pushing to restructure the military concept of defense to become responsive and adaptable and tailored to the substance of the reforms in the defense. The main problem faced by Indonesia to develop a domestic defense industry is the inability of industry and education sectors to absorb the fundamental aspects of the Revolution in Military Affairs (RMA). This inability does not allow Indonesia to experience significant breakthroughs in the application of RMA. So with reference to the condition necessary to anticipate concrete steps in developing a systematic plan to build the defense industries are able to anticipate the revolution in military affairs. Among priorities at once by selecting the appropriate stages of the development plan which includes the development of Main Equipment Weapon System, Spatial Planning Area Defense, Civil Defense Development, and Spatial Structure of the Organization. And one of its efforts 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 quality and quantity so that is always ready to face any condition of any contingency that would happen. Determining policy location Arsenal first location contains more choices in environmental issues multi-objective and multicriteria decision, then the model is proposed to be the appropriate methodology to accommodate the qualitative preference and priority-setting objectives/criteria for future development is to approach the Analytical Hierarchy Process (AHP). Principle of the AHP method is to break breaking a complex situation and unstructured, into its component parts, arranging these variables in a section or an order of hierarchy, giving numerical values to subjective considerations about the relative importance of each variable and analysis various considerations is to determine which variables have the highest priority and act to influence the outcome of the situation. From the results of the solution by using the AHP method showed that the first priority location determination Arsenal 1 in the eastern region is a factor analysis of logistics operations to support operations capabilities in the integrated logistics support system that effectively and efficiently. And the locations selected for Arsenal's first priority location is in the eastern region Lantamal Ambon.
