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.

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. 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

This study aims to examine the social values and characteristics contained in the short story 'Tupai Si Pantang Surrender' written by SDN 13 KOLO BIMA. The theory used is the theory of humanism put forward by Abraham Maslow with a sociology of literature approach. The method used in this research is a descriptive method with a qualitative research form. The subject of this research is the short story Tupai Si Unyielding' which was written by SDN 13 KOLO BIMA. The research data is in the form of paragraph excerpts and sentence fragments that contain elements of social values. The results of the study show that the social values contained are, 1) unyielding attitude, 2) compassion, 3) respect not demeaning, 4) persistence and hard work produce results according to what we use, 5) struggle, 6) admiration, 7) Regret. This study delves into the analysis of social values and characteristics embedded in the short story titled "Tupai Si Never Give Up," authored by SDN 13 Kolo Kota Bima. The research aims to uncover the narrative's underlying themes, socio-cultural reflections, and character dynamics. Employing a qualitative approach, the analysis focuses on the portrayal of social values such as perseverance, resilience, and community bonds, as well as the depiction of various characteristics exhibited by the story's protagonists. Through a close examination of the narrative elements, the study seeks to contribute to a deeper understanding of the cultural and social nuances presented in the short story, shedding light on the author's intent and the broader societal context in which the narrative unfolds.

Abstract

Di Sekolah Dasar Bundo Kandung yang telah kami survei, ternyata sekolah tersebut tidak memiliki sarana dan prasana yang berbasis IT di ruang membacanya. Bahkan sekolah tersebut juga belum bisa membuat perpustakaan yang sangat bagus dan lengkap. Mereka hanya mempunyai ruang baca dengan ukuran yang sangat kecil, yang hanya menampung 8 orang saja untuk dapat bisa membaca. Lapangan sekolah yang luasnya 900 meter, akan diambil sedikit lahannya untuk pembuatan taman baca berbasis digital. Kehadiran Pojok Literasi Berbasis Digital ini membawa misi khusus yaitu membudayakan minat baca peserta didik yang sejauh ini masih dinilai rendah. Serta memberikan fasilitas yang nyaman dan kondusif bagi siswa untuk meningkatkan literasi informasi. Literasi informasi merupakan kemampuan seseorang dalam mencari, mengoleksi, mengevaluasi atau menginterpresentasikan dan mengkomunikasikan informasi dari berbagai sumber secara efektif dan efisien. Oleh karena itu tim pengabdian akan membuat taman berbasis digital yang dapat menampung lebih banyak lagi peserta didik dalam meningkatkan minat literasinya. Tim pengabdian juga menggunakan media aplikasi Ruang Guru dalam membantu peserta didik dan guru untuk proses belajar dan mengajar di Sekolah Dasar Bundo Kandung.
