Abstract

Near Field Communication (NFC) technology has become ubiquitous in various applications, from contactless payments to data transfer between devices. As the use of NFC expands, ensuring the security of transmitted data becomes paramount. This research investigates the application of Hill Cipher, a linear algebra-based encryption technique, to enhance the security of data transmitted via NFC. In the field of contemporary wireless technology, near-field communication (NFC) stands out as an important force, enabling contactless transactions and the seamless exchange of information between electronic devices. This research explores the innovative integration of NFC into the attendance input process, which is linked to a website-based attendance system. NFC's adaptability, which was initially prominent in payment cards, has expanded across industries, empowering smartphones, tablets, and wearable devices. This study contributes to the ongoing development of NFC technology, proposing a renewable solution for student attendance systems. With a vision of increased efficiency, this research anticipates increased utilization of time and resources, thereby providing a promising path for the advancement of attendance management. A comprehensive evaluation of the proposed NFC data security solution was conducted through simulations and practical implementations. The research assesses the impact on communication speed, energy consumption, and overall system performance. Results indicate that the integration of Hill Cipher introduces a negligible overhead on communication speed, making it a viable option for real-time NFC applications. Furthermore, the study addresses potential vulnerabilities and threats associated with NFC technology, emphasizing the role of Hill Cipher in mitigating risks such as eavesdropping and unauthorized data interception. The research considers practical implementation challenges and proposes strategies for seamless integration into existing NFC-enabled devices. In conclusion, this research contributes to the ongoing discourse on NFC data security by introducing Hill Cipher as a robust encryption mechanism. The findings underscore the feasibility of implementing this encryption technique without compromising the efficiency of NFC communication. The proposed secure communication protocol holds promise for enhancing the privacy and integrity of data transmitted via NFC, fostering trust in the expanding ecosystem of NFC-enabled applications.

This study contributes to the ongoing development of NFC technology, proposing a renewable solution for student attendance systems. With a vision of increased efficiency, this research anticipates increased utilization of time and resources, thereby providing a promising path for the advancement of attendance management. Attendance tracking is a critical aspect of educational and organizational management, with traditional methods often plagued by inefficiencies and inaccuracies. This research explores the implementation of Near Field Communication (NFC) tags as a modern solution for attendance data collection. The study aims to assess the effectiveness of NFC technology in improving accuracy, efficiency, and real-time access to attendance information. The research employed a mixed-methods approach, incorporating a pilot study in an educational setting. NFC tags were distributed to participants, allowing for contactless attendance registration. Data was collected through observations, user feedback, and system logs. Additionally, a comparative analysis was conducted between NFC-based attendance tracking and traditional methods. Findings indicate a substantial improvement in accuracy and efficiency with NFC tags compared to traditional methods. Real-time data access provided administrators with up-to-the-minute attendance information, enabling timely interventions and streamlined record-keeping. User feedback highlighted the ease of use and convenience of the NFC-based system.

Abstract

Structured and effective student governance is one of the keys to success in creating a dynamic and productive academic environment at the Politeknik Negeri Medan. In an effort to increase transparency and efficiency in the management of student activities, especially related to activities, competitions and scholarships, it is necessary to implement an integrated Student Performance and Governance Information System. This system will cover various student activities, from organizations, social activities, to self-development, as well as three main competition categories: Sports and Arts Competitions, and Academic Competency Competitions. Scholarship management is also the main focus to provide financial support to students who excel or need assistance. With this integration, Politeknik Negeri Medan can improve data management efficiency, strengthen supervision, and provide easier and faster access to all parties involved, thereby creating a learning environment that is more structured and oriented towards achieving academic and non-academic achievements.

Abstract

Politeknik Negeri Medan (Polmed) has various business units that support academic and non-academic activities. However, performance management and business governance of these units face various challenges, especially due to the use of manual and non-integrated systems. The main problems faced include inaccurate data, information delays, difficulties in monitoring and evaluation, and inefficient document management. This research aims to develop an integrated Performance and Business Governance Information System to collect data, manage and present business reports in the Polmed business unit. This system is expected to increase the accuracy and speed of data processing, facilitate access and presentation of information for management, and increase efficiency in monitoring and evaluating business unit performance. Apart from that, this system is also expected to optimize the management of business documents and reports. Through a research and development (R&D) approach, this system was designed and implemented by utilizing the latest information technology. The research results show that the implementation of this information system is able to overcome various existing problems, as well as support improved performance and governance of the Polmed business unit. Thus, this research makes a significant contribution in supporting the vision and mission of Polmed as a superior educational institution.

Abstract

Development of an Integrated Attendance System at the Private Senior High School (SMA) Nur Azizi Tanjung Morawa: Messenger API Integration to Improve Parent-Guardian Communication and Monitor Student Attendance in Real-Time. Advances in information and communication technology have influenced various aspects of life, including education. One technology implementation that is increasingly common is a Radio Frequency Identification (RFID) based attendance system. However, although this system provides the advantage of automatically recording student attendance, delays in providing information to parents regarding student attendance is a major obstacle. To overcome this problem, this research aims to develop and implement a messenger API in the attendance system at Nur Azizi Tanjung Morawa Private High School. This integration is expected to strengthen communication between schools and parents and monitor student attendance in real-time.

Abstract

Nur Azizi Private High School, located in Tanjung Morawa, Deli Serdang Regency, is one of the schools with A accreditation which continues to be committed to improving educational services. However, currently the delivery of information in this school still relies on manual wall magazines, which results in slow distribution of information, lack of interest in reading among students, teachers and staff, as well as dependence on print media. As technology develops, more effective solutions are needed to manage and convey information quickly, directly and accessible anytime and anywhere. Based on the results of discussions with the school, Nur Azizi Private High School needs a digital media that is easy to use, user-friendly, and can speed up the dissemination of information. Therefore, the community service team plans to implement a broadcasting system in the form of a digital website with an auto-reload feature that will be integrated with smart TVs. The implementation of this system is expected to increase the efficiency of delivering information and support the need for faster, more accurate and modern communication at Nur Azizi Private High School. Initial evaluations showed an improvement in the quality of infrastructure and student interest in accessing school information through more modern media.
