Abstract

Handling information security management is an absolute thing to do for organizations that have information systems to support the organization's operations. Information systems consisting of assets both software and hardware that manage data and information that are spread over networks and the internet, make it vulnerable to threats. Therefore investment and costs are needed to secure it. Costs incurred for this need are not small, but investment expenditures and information security costs carried out need serious handling to be more effective and on target. The System Dynamics Model is used to evaluate alternative strategies to demonstrate the effectiveness of investment and the cost of managing information security through simulation of policy changes. System Dynamics are methods for describing models and systems analysis that are dynamic and complex, consisting of variables that influence each other in the form of causal relationships and feedback between variables that are either reinforcing or giving balance. Simulation using a dynamic system model in this study illustrates that the management of risk assessment followed by vulnerability reduction efforts has a very large impact on the management of information security. By making a difference in the value of security tools investment, this provides an alternative choice in information security risk management investments to achieve the effectiveness of the overall costs incurred in managing information security

Abstract

Warships are one of the main components of the Navy having the main task of maintaining national security and defense at sea. Based on a research study in 2019, the age of warships over 30 years is 60% which has an impact on the decline in the performance of warships. A strategy is needed to improve the performance of warships to achieve the implementation of its main duties and functions as a means of defense. To solve this problem, it is necessary to pay attention to and consider several aspects, both internally and externally through the dynamic system approach method with the Causal Loop Diagram (CLD) model which emphasizes the impact of dynamic aspects associated with influential cause and effect problems. The selected strategies include human resource development, operational readiness, capability development, and increased interoperability. Keywords : CLD, STELLA, System Dynamiic.

Abstract

Lombok Strait is one of 9 chokepoints (narrow point) of the world. Lombok Strait is also one of the 3 lanes of the Indonesian Archipelagic Sea Lanes (IASL) contained in the IASL II which consists of the Makassar Strait and Lombok Strait. Lombok Strait has a depth of more than 150 meters and is a liaison between the Pacific Ocean and the Indian Ocean is very strategic for the submarine trajectory. So it is very important information about the water column in the Lombok Strait for military war operations needs. Therefore, the validity of accurate data is very important, by way of filtering CTD data. The goal is to know the thermocline characteristics and sound speed in the Lombok Strait. One of the methods used for CTD data filtering is by using Analysis Toolpak. Results from CTD data processing using Analysis Toolpak show that there is a difference between data profiles before and after filtering. It also can be seen that the characteristics of the thermocline of the Lombok Strait from North to South are increasingly tight or thin with a thickness of 146.094 meters to 87.694 meters. While the sound speed characteristics in the Lombok Strait from North to South direction also increasingly tight or thin with the difference in the value of sound speed from 34.547 m/s to 27.538 m/s. The seawater mass in the thermocline layer is thought to have originated from the North Pacific Intermediate Water (NPIW) which enters the Lombok Strait through the northern part of the Lombok Strait with an average salinity of 34,415 psu at an average depth of 42.504 meters. Based on the above data it is very important to filter the CTD data to produce valid and accurate data before further processing. Keywords: Filtering, Lombok Strait, Sound Speed, Thermocline.

Abstract

ABSTRACT This paper describes the application of the Analytic Network Process (ANP) method in submarine selection as one of the defence equipment with very strategic value, the procurement of submarines is directed at realizing a deterrence strategy and a strategy of balancing with state actors that have the potential to threaten the sovereignty of the Republic of Indonesia. Apart from threats, the procurement of submarines also considers the geographical constellation of the Republic of Indonesia and the government's wishes, such as the interest of the minister of defence during visits to countries that offer their submarines. Therefore, before the procurement, an analysis was made in terms of the selection of submarine alternatives, both analysis of information and identification of various essential and interrelated requirements regarding data from submarine alternatives that would later be selected. In addition to other options, it is hoped that the main criteria for selecting submarines will be known. In submarine procurement decisions, where the existing problems cannot be arranged in a hierarchical form because it involves the interaction and dependence of the higher-level elements on the lower-level elements. Therefore, in this study the ANP method is used, which can accommodate the linkages between criteria or alternatives. The results obtained are the most substantial alternative priority weight on the S-Class submarine made by P-Country of 0.383283. While the results of the importance of the criteria are sequential starting from the sensor criteria of 0.125127, Threat 0.089076, Neighbors power state 0.080153, Geographical conditions 0.75735, Interoperability 0.071664, Weaponry 0.068672, Navigation 0.047301, Platform 0.044235 and finally Machinery 0.020580. Keywords: ANP method, Submarine, Alternative priority.

Abstract

In order to maintain maritime security, especially in the Lantamal V Surabaya working area, the patrol ship unit elements must be ready to deal with all incidents with quick responses. Therefore, it is very necessary to have the most precise patrol ship specifications to carry out tasks that are faced with frequent vulnerabilities, and are also faced with a limited state defense budget. This research proposes the use of the integration of the Fuzzy MCDM and BCA methods in selecting the type of Satrol ship. The Fuzzy MCDM method is considered very appropriate for the problem of fuzzy criteria weights. The BCA method is used to analyze the benefits and costs that will occur as a consequence of the operation of the ship. Based on this research, it is concluded that from the available alternatives, the best Patrol ship that should have been selected for the development/ procurement of Satrol ship is "C" Class ship with a value of 0.6073 using the Fuzzy MCDM method and 1.03 using the BCA method. The results of this research are expected to be input and considerations for the leadership of the Indonesian Navy in the development of future Satrol ships. Keywords : Satrol ships, Lantamal V, Fuzzy MCDM, BCA

Abstract

ABSTRACT The global dynamics that are uncertain is one of the main factors affecting the success of achieving the 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 consideration of the development of the strategic environment that is constantly changing will affect the planning process for the development of the Indonesian Navy, one of which is increasing the operational capability supported by logistical capabilities. In particular, the need for ammunition and weapons that are included in the class V provision to support KRI in an operation. Therefore, it is very necessary to have an Arsenal area warehouse specifically for the Koarmada II region. The speed and accuracy of class V supply support for the KRI elements of the Koarmada II region can be seen from the huge function and role of logistical support, especially in the field of ammunition logistics support distribution, a thought is needed to establish another Arsenal regional warehouse to assist the duties and roles of Arsenal Batu Poron. The choice of location determination has several factors that need to be considered so that it is categorized in a multicriteria decision environment, so the proposed model is the right methodology to accommodate the criteria divided into qualitative and quantitative by using the Fuzzy MCDM (Multi Criteria Decision Maker) approach. Qualitative criteria for selecting the best warehouse location in Arsenal area include security criteria, transportation access, and warehouse support facilities, while quantitative criteria include distance to enemies, distance to settlements and earthquake factors that affect the construction of Arsenal area warehouses. In this study, from five alternative locations, namely Lantamal V Surabaya, Lantamal VI Makassar, Lantamal VII Kupang, Lantamal VIII Manado and Lantamal XIII Tarakan. Keywords: Strategic Environment, Arsenal area warehouse, Fuzzy MCDM, facility design.

Abstract

ABSTRACT The dynamics in the development of the security situation are so rapid that there are many political policies that change the security situation of a Country. So that everyone competes to create a technique so that the designed method can be applied especially in the field of security. Indonesia is one of the island states that has an area of sea 2/3 of the land so the source of natural wealth is very abundant, this causes many conflicts of interest with neighboring countries. The number of violations of the Lanal Tarempa region in the Natuna Sea as an example. In the calculation between the degree of violation over time and the application of proper operating patterns it takes a method with a forecasting calculation system (Forcasting) in this case using the Time Series Double Holt Winters Exponential Smothing by combining Holt's (Double Exponential Smoothing) model as a closed system model with the Bayesian Network model as an open system model. This proposed model has the ability to follow a significant pattern of actual data movement. The number of illegal fishing violations based on the data of the last 4 (four) years. The accuracy of an analysis if in the processing of forecasting data results in a small α (Alpha) and β (Beta) value as well as mape, MSE and MAE correction values. KEYWORDS: Security Situation, Breach, Tarempa Naval Base, Operation Pattern, Forecasting and Bayesian Network Model.
