Abstract

Secretariat section or Indonesian Naval Technology College Secretariat Section is a work unit under Setlem as the secretary of the institution in charge of administering administrative services in the form of correspondence. Good incoming mail management procedures include; grouping of letters, checking of mail, recording of lmail and distributing mails as well as filing of mails, while for outgoing mail include; drafting mails, mail draft approval, letter typing, numbering, lmail preparation, mail delivery. At this time the mail processing process is still done manually so that it affects the decision making quickly and accurately and minimizes errors. To build a service unit that is integrated and capable of providing excellent service quality, it is necessary to have a management that encourages efficiency and accelerates the process of implementing service tasks and functions. The management includes the Standard Operation System (SOP) and the implementation of E-Office for the implementation of the duties and functions of the service unit as well as the documentation or archive system. With the website-based mail information system in the Indonesian Naval Technology College environment, all forms of mail, both incoming and outgoing letters, will be carried out electronically, which is integrated from the Commander to the Work unit Work unit below. From the results of this study, the ease of processing letters can help in making decisions accurately and quickly. Keywords: E-Office, Indonesian Naval Technology College Secretariat section, Information System, mail.

Abstract

The medical checkup (MCU) information system is essential for maintaining activities in hospitals and health facilities. Development of a system that prioritizes the security of patient data and information contained therein. In military hospitals, patient condition data is soldier condition data that must be guaranteed security against various forms of data and information leaks. Thus, an appropriate security method is needed that can support the prevention of various forms of cybercrime attacks and data leaks. The military has more than one hospital that was established to support various military operations, so the system used is also an integrated system that can reach all existing hospitals and health facilities.

Abstract

National defence in the seas faces increasingly complex challenges due to developments in information technology. Cyber threats are a significant threat to national security, including in the context of national defence at sea. Therefore, the Indonesian Navy as a component of national defence needs to apply sophisticated information technology to deal with this threat. This study aims to analyse the application of Indonesian Navy information technology in dealing with cyber threats to support national defence at sea. The method used in this study is a qualitative method with a case study approach. This research involved collecting data through in-depth interviews, participant observation, and analysis of related documents. The results of this study indicate that the Indonesian Navy has implemented various innovative information technologies to deal with cyber threats. The application of this information technology involves Information Technology Infrastructure (hardware), the readiness of the Required Cyber Operation Software and Human Resources (brain ware), as well as the development of cyber capabilities within the organization. Through the application of this information technology, the Indonesian Navy can support national defence at sea more effectively

Abstract

The rapid development of urbanization and security concerns has prompted the integration of automated smart surveillance systems to enhance public safety and operational efficiency. Traditional surveillance methods often rely on human monitoring, which is prone to errors and inefficiencies. Image processing and computer vision techniques provide a solution by automating object detection, tracking, and anomaly recognition. This study aims to investigate advanced image processing and computer vision techniques for improving the performance of automated smart surveillance systems. A hybrid approach combining convolutional neural networks (CNNs), attention mechanisms, and edge computing is proposed to enhance both detection accuracy and real-time processing speed. The research employed experimental design, utilizing a dataset of 12,000 annotated image frames and 85 hours of video footage from diverse environmental conditions. Performance metrics such as precision, recall, mean average precision (mAP), and processing speed were measured. Results demonstrate that the proposed model outperforms traditional CNN models, achieving higher detection accuracy and faster processing speed. The study concludes that integrating edge computing with adaptive image processing and attention-based neural networks significantly improves automated surveillance system performance in real-world settings. These findings offer valuable insights for the development of scalable and efficient smart surveillance technologies.

Abstract

The rapid growth of the Internet of Things (IoT) has introduced significant security challenges due to the increasing interconnectivity of devices and the sensitive nature of the data exchanged. Securing IoT communications is crucial to prevent unauthorized access, data breaches, and cyberattacks. However, traditional cryptographic methods often fail to meet the unique needs of IoT systems, which are constrained by resource limitations such as processing power and energy consumption. This research aims to develop a comprehensive information security framework that integrates cryptographic protocols tailored to secure IoT communications while maintaining efficiency. The study employs a mixed-methods approach, combining simulation-based experiments and expert interviews. Various cryptographic techniques, including AES, RSA, and Elliptic Curve Cryptography (ECC), are evaluated in IoT network configurations across different environments. Performance metrics such as encryption time, energy consumption, and data integrity are measured to assess the framework’s effectiveness. The results demonstrate that ECC offers the best balance between security and resource consumption, outperforming AES and RSA in terms of efficiency. Expert feedback confirms the feasibility and scalability of the proposed framework. This research contributes to the field by offering a novel approach to IoT security that can be applied to real-world networks, ensuring secure and efficient communication.

Abstract

The rapid growth of cloud computing, large-scale data centers, and heterogeneous network traffic has exposed structural limitations in traditional distributed routing architectures. Conventional switching and routing mechanisms often lack global network visibility, resulting in suboptimal path selection, inefficient bandwidth utilization, and delayed convergence under dynamic traffic conditions. This study aims to design and evaluate a Software Defined Networking (SDN)-based optimization framework to enhance switching and routing performance through centralized programmability and adaptive traffic engineering. A quantitative experimental design was employed using network emulation across small-, medium-, and large-scale topologies. Comparative analysis was conducted between conventional routing protocols and the proposed SDN-based model. Performance metrics included throughput, end-to-end delay, packet loss rate, convergence time, and bandwidth utilization efficiency. Inferential statistical testing was applied to validate performance differences. Results demonstrate statistically significant improvements under the SDN framework, including increased throughput, reduced latency, lower packet loss, and faster failure recovery. Performance gains were more pronounced in large-scale and high-traffic scenarios, indicating strong scalability and resilience characteristics. The findings confirm that centralized control architecture fundamentally enhances routing optimization and network adaptability. SDN-based approaches provide a scalable and efficient solution for modern programmable network infrastructures.
