Abstract:This study developed and evaluated a standalone, non-intrusive radio frequency identification (RFID)-based elevator access control system for a four-story residential building. The system used an Arduino Uno, an MFRC522…
RFID reader, and relay interfaces to regulate access to Floors 2, 3, and 4. Authorized card identifiers and floor permissions were stored locally, enabling offline operation without an external database or network connection. The relays interfaced only with the elevator push-button circuits and did not modify the original controller, motor drive, door mechanism, or safety system. Performance was evaluated using 47 registered cards and three unregistered cards, with each card tested 50 times, producing 2,500 authentication trials. Under the tested conditions, all registered cards were correctly authenticated according to their assigned floor permissions, while all unregistered cards were rejected. The system achieved 100% authentication accuracy, 100% correct relay activation, and 100% unauthorized-card rejection. Stable card detection was obtained at distances of up to approximately 1 cm. The first-floor button remained independent of the RFID module to preserve minimum accessibility during module failure. The proposed system provides a practical and low-cost retrofit solution for floor-specific elevator access control in small residential buildings.

not been optimally implemented. This study implements the 128-bit Advanced Encryption Standard (AES) algorithm combined with Huffman compression to protect the confidentiality and integrity of student grade files in Excel (.xlsx) format, and evaluates its effectiveness through functional, performance, and security testing. The system was developed as a Python desktop application with a CustomTkinter interface, in which the encryption process runs Huffman compression before AES-128, while integrity verification uses SHA-256 hashing. Testing was conducted on seven student grade files from MA Ma'ahid Kudus. The results show that all files were successfully encrypted and decrypted without failure or data alteration, with encryption times of 0.0142-0.0828 seconds and decryption times of 0.0046-0.1417 seconds. The SHA-256 hash values of the original and decrypted files were identical for all samples, yielding 100% recovery accuracy, while the file size increase from padding and header insertion ranged only from 1,092 to 1,101 bytes. The study concludes that the combination of AES-128 and Huffman compression is an effective and efficient solution for protecting student grade data in educational institutions.

e the perceptions and experiences of beginner investors in making investment decisions in the digital era. Using a qualitative research approach with a phenomenological perspective, data were collected through semi-structured interviews with beginner investors who actively use digital investment applications. The collected data were analyzed using thematic analysis to identify patterns and themes related to investors’ experiences and decision-making processes. The findings reveal that investment decision-making among beginner investors is influenced by several interconnected factors, including the accessibility and usability of digital investment platforms, the influence of social media and online communities, the development of financial literacy, and psychological experiences related to investment gains and losses. Digital investment applications play a crucial role in lowering barriers to market participation by providing user-friendly interfaces and accessible financial information. However, reliance on social media as a source of investment information may also expose investors to misinformation and speculative investment behavior. In addition, emotional responses such as confidence, fear, and uncertainty often influence investment decisions among beginner investors. Overall, the study highlights that investment decision-making in the digital era is a multidimensional process shaped by technological accessibility, social influence, financial knowledge, and psychological factors. These findings contribute to a deeper understanding of investor behavior in digital financial environments and emphasize the importance of financial education and responsible investment practices.

h applies the Technology Acceptance Model (TAM) developed by Davis (1989), emphasizing two key constructs—perceived ease of use and perceived usefulness—as determinants of users’ attitudes and decisions. The study employs a quantitative approach using a survey method involving 100 lower-class customers of Bank Syariah Indonesia (BSI) Sibuhuan. Data were analyzed using Structural Equation Modeling (SEM) with the Partial Least Squares (PLS) technique through SmartPLS 4.0 software. The results indicate that perceived usefulness significantly affects both attitude and decision to use, while perceived ease of use influences attitude indirectly. The R² value for attitude (0.743) and decision (0.654) shows that the model has strong explanatory power. These findings reveal that lower-income customers are more motivated by perceived benefits, such as convenience, time efficiency, and transaction security, rather than interface simplicity. From a practical perspective, the study suggests that Islamic banks should strengthen digital literacy, user assistance, and customer trust to enhance mobile banking adoption among lower-class communities.

Abstract:Abstract: Hospitals, as healthcare facilities, have a high level of visitor mobility, particularly in inpatient wards. Therefore, visitor control is necessary to maintain patient comfort, safety, and service quality. Manual…
ual visitor monitoring is considered ineffective and prone to errors. Therefore, this study aims to design and implement an artificial intelligence-based visitor monitoring system for hospital inpatient wards using computer vision technology. The developed system utilizes the YOLOv8 model as an object detection algorithm to automatically detect and count visitors through a camera. Visitor information is displayed through a desktop-based monitoring interface and is equipped with warning notifications via the Telegram application and an automatic alarm if the number of visitors exceeds the limit set by hospital policy. Test results show that the system is capable of performing well in detecting and counting visitors in real time, as well as sending information and warnings responsively. Thus, this system is considered effective as a technology-based hospital management support solution in controlling inpatient ward density and making decisions more quickly and accurately.

Abstrak: Rumah sakit sebagai fasilitas pelayanan kesehatan memiliki tingkat mobilitas pengunjung yang tinggi, khususnya pada ruang rawat inap, sehingga diperlukan pengendalian jumlah pengunjung untuk menjaga kenyamanan, keselamatan pasien, dan kualitas pelayanan. Pemantauan jumlah pengunjung secara manual dinilai kurang efektif dan rentan terhadap kesalahan. Oleh karena itu, penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pemantauan jumlah pengunjung ruang rawat inap rumah sakit berbasis kecerdasan buatan menggunakan teknologi computer vision. Sistem yang dikembangkan memanfaatkan model YOLOv8 sebagai algoritma object detection untuk mendeteksi dan menghitung jumlah pengunjung secara otomatis melalui kamera. Informasi jumlah pengunjung ditampilkan melalui antarmuka pemantauan berbasis desktop dan dilengkapi dengan notifikasi peringatan melalui aplikasi Telegram serta alarm otomatis apabila jumlah pengunjung melebihi batas yang ditetapkan sesuai kebijakan rumah sakit. Hasil pengujian menunjukkan bahwa sistem mampu bekerja dengan baik dalam mendeteksi dan menghitung jumlah pengunjung secara real-time, serta mengirimkan informasi dan peringatan secara responsif. Dengan demikian, sistem ini dinilai efektif sebagai solusi pendukung manajemen rumah sakit berbasis teknologi dalam pengendalian kepadatan ruang rawat inap dan pengambilan keputusan yang lebih cepat dan akurat.
