Abstract

Disinfolahta’s second naval fleet command has the Main task of assisting with the field of development, data collection, and processing as well as presenting information, research, and development within the Koarmada II environment and acting as an information technology service center. Telegraphic communication radio within the Indonesian Navy is used for long-distance communication between ships, aircraft, and international shore radio. RTG Telegraphic communication radio uses international Morse signs, Q codes, and Z code procedural signs to convey information or news. The application of Radio Communication Telegraphy is very vulnerable to information theft. Important information conveyed from ship to ship, ship to aircraft, or to shore radio or vice versa can be accessed publicly. Information system security defense at Disinfolahta Koarmada II has not shown a level of efficiency and effectiveness, due to the absence of a special section in the field of information system security issues related to data transactions in communication networks. Improvement or improvement of information security is needed which plays a role in maintaining the confidentiality of information. Increasing the security and confidentiality of information is very necessary so that important information that is distributed is not known by unauthorized parties. This study plans a communication protocol scenario using the Mavlink and AX2.5 communication protocols. Each scenario will be run using a simulation to get network performance. The results of network performance measurements will be modeled using a dynamic system to get the best communication protocol as a proposal in order to improve the information security system at the Second naval fleet command. Keywords: RTG, Mavlink, AX2.5, network performance, communication protocols

Abstract

The Indonesian Archipelagic Sea Lanes (ALKI) which connects the Indian Ocean region with the Pacific Ocean and East Asia with Australia, has enormous consequences for efforts to implement its safeguards. An alternative is needed to optimize the current detection system. One of them is by utilizing the latest technological developments through the use of Unmanned Aerial Vehicles (UAV). The UAV capability for security and defense purposes at sea needs to be developed as an Integrated Fleet Weapon System (SSAT) to fulfill the functions of tactical reconnaissance and maritime surveillance (Surveillance). The use of the UAV can also increase strength and complement the needs of maritime patrol aircraft (Maritime Patrol Aircraft / MPA) which so far have not been fulfilled quantitatively in covering all Indonesian national jurisdiction waters. The ALKI I area is in the working area of Fleet Command I (Koarmada I). In order to optimize the placement of the ScanEagle UAV in the ALKI I area, it is very important to know the criteria for determining its location. This is also due to the limited number of ScanEagle UAVs and the large area that must be covered by these UAVs. By obtaining the location criteria for the ScanEagle UAV Landbase, it is hoped that it will make it easier to map ScanEagle placement locations at Indonesian Navy bases in the ALKI I area. ANP and TOPSIS methods. The criteria for determining the location of the UAV consist of geographical location, weather conditions, vulnerability and security as well as logistical facilities and support, with sub-criteria mountains, tall buildings, plains, sunny cloudy, rain, territorial violations, piracy crimes, smuggling, SAR, airport, ports, spare parts, maintenance, fuel and electricity availability. Based on the results of the analysis and discussion of determining the location of the selected UAV Batam Naval Base. Keywords: UAV, SSAT, Surveillance, ScanEagle, ANP, TOPSIS

Abstract

Assignment Marine security operation is an operation where the presence at sea has strategic value for theexistence of national sovereignty and maritime security in Indonesia's national jurisdiction. The threat of securitydisturbances and violations at sea in the form of fishing theft, theft of timber and other natural resources as wellas encroachment on territorial boundaries by foreign ships requires the presence of the Indonesian Navy PatrolElements (Ships and Aircraft) for security. The limited number of TNI AL Patrol Elements and the budgetprovided by the state as well as the need for securing the maritime territory of the Republic of Indonesia hasresulted in the need for thinking about optimizing the assignment of Patrol Ships and Aircraft in the Kamlaoperation sector and placement to their supporting bases, so that the right type and amount and operationalcosts in security. Ships and aircraft carry out patrols in randomly determined sectors. This optimization modelidentifies the related decision variables through open interview discussions, then sets the objective andconstraint functions as an optimization model to be developed. The application of the Goal Programmingmethod can be formulated by determining the decision variables related to the assignment of aircraft where theobjective function is to calculate the maximum radar coverage area in the operating sector and minimizeoperating costs. After optimizing the coverage area, there was an increase of 2.5% and a decrease in operatingcosts of 28%. So that, Mamdani's Fuzzy Logic method is used to determine the output of certain radar coverageareas. In this case, it requires the help of Matlab software on the Fuzzy Inference System (FIZ) toolbox to solvethis problem. Keywords: Maritime Patrol Aircraft, Operating Costs, Goal Programming, Fuzzy Inference System
