Abstract

KRI is a representation of the strength and ability of the Indonesian Navy in maintaining state sovereignty in the maritime jurisdictional area. The complexity of the threat in the area of operation will determine the amount, type and level of readiness of the KRI that will carry out the operation. Therefore, information on the level of readiness of the KRI "Ready for Combat", "Ready for Operation" or "Not Ready" is very important for Sops as a basis for selecting the KRI for carrying out operations. The purpose of this research is to create a model of KRI readiness assessment that is relevant to current conditions and according to the needs of the organization. In this study using the Analytical Network Process (ANP) method to determine the weight of the assessment criteria including technical ability, spare parts, ammunition, personnel and glagaspur. Furthermore, in the calculation using the direct measurement method. The results of weighting data processing using the Analytic Network Process (ANP) show that the technical ability with a value of 0.359, spare parts 0.053, ammunition 0.034, personnel 0.113, and glagaspur 0.441. In the assessment of KRI HBS-382, it was found that KRI HBS-382 had readiness at the level of "ready for operation" with a value of 71.1%, while the assessment on KRI REM-331 has a readiness level of "not ready" even though the final value is 79.3%, this is because the ammunition criteria are "not ready" with a value of 59.9. The results of the study, it can be concluded that the KRI readiness assessment model can be used to assess all types of KRI. This readiness assessment model has several advantages that the old assessment model does not have, including making it easier for the KRI to measure and determine the level of readiness of the KRI, making it easier for Sops to determine the amount and type of KRI for operations as needed, and Logistic community oversight in planning maintenance, repair, and overhaul (MRO). Keywords: Marine security operations, Readiness, (ANP), Assessment.

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

To Keep Indonesian defense, the TNI has one of the main tasks, namely carrying out War Military Operations (OMP). One form of this operation is the amphibious operation, which is a military operation launched from the sea by the Indonesian Navy's marine units and landing troops loaded on ships and involving air power. In its implementation, amphibious operations exercises contain potential risks that can endanger the safety of personnel and defense equipment materials. Several accidents in amphibious operations have been experienced by the Indonesian Navy. The purpose of this study is to determine the risks that exist in amphibious operation activities and then measure the risk value in amphibious operation activities so that risk control proposals can be made. The method used in this study is HIRARC. The HIRARC method is widely used in the world and is very suitable to be applied in conducting a risk analysis because it is considered complete enough to include the process of risk identification, risk assessment and risk control. Based on the risk analysis using HIRARC, it is known that amphibious operation training activities have 84 potential risks with 19 risks at the extreme level, 27 risks at the high level, 29 risks at the moderate level and 9 risks at the low level. While the highest risk value is in the attack stage with a risk value of 297. With the research results that have been obtained, several proposals for risk control and appropriate risk mitigation can be proposed in order to realize the Navy towards zero accident.

Abstract

The future threat to the world, including Indonesia, is natural disasters. The Navy as a means of state defense places natural disaster management as a form of military operation task other than war. Landing Ship Tank (LST) type warship is a defense system capable of delivering logistics on a large scale directly to disaster locations via beaching. The main problem is still finding delays and failures in logistics delivery caused by equipment damage with the biggest loss being the sinking of warships. The aim of the research is to minimize the occurrence of risk events by making a risk management design based on the ISO 31000 framework which focuses on warship operations. The method used by the House of Risk (HOR) is divided into two stages. HOR stage 1 focuses on ranking the Aggregate Risk Potential (ARP) value with the help of a Pareto diagram to determine the selected risk agent, which then requires treatment on a priority scale. The results of the HOR stage 1 are then entered into the HOR stage 2 to obtain the most effective preventive action. The results obtained, there are 8 risk agents that need to be handled. Furthermore, based on brainstorming with the Expert (the commander of the warship) obtained 12 mitigation actions that can be implemented immediately. Keywords: Risk Analysis, Landing Ship Tank, HOR

Abstract

The formation of the III Fleet Command in the development and development of the Indonesian Navy's strength has a strategy of developing a strong posture. The development of the TNI AL posture that has been determined includes the level of ability, strength, and pattern of strength degrees. One of the strength postures built and developed is submarines. To support the optimization of submarine operations in the Koarmada III area, it is necessary to build supporting facilities to extend the capability of the submarine's operating range, namely special submarine base facilities. The purpose of this study is to analyze the criteria that are considered and determine the priority of the location of the submarine base in the Koarmada III area. This research was carried out in three stages, namely the stage of determining the criteria using the Delphi method, the stage of weighting the criteria using the ANP method, the stage of ranking alternative locations using SAW. In the first stage of the analysis, ten main criteria were found in determining the location of the submarine base which were then used as the basis for the second stage of analysis, namely the determination of the structure and weighting of the ANP. The results of the weighting of the criteria are used for the third analysis process, namely the ranking of alternatives using the SAW method. The results of the SAW processing prove that Ambon is the main priority in determining the location of the submarine base in the Coarmada III Region with the SAW value = 0.858 with a weight of 27.8%. The results of this study are expected to be a consideration for the leadership of the Indonesian Navy in determining the location of submarines in the future.
