Abstract

The conventional attendance process takes a long time during attendance and also during recording. Absenteeism recapitulation helps teachers monitor student attendance in class. In addition, attendance recapitulation can be one of the considerations in the assessment. The information system can help the conventional attendance recapitulation process become automatic. Vocational High School (SMK) Negeri 9 is a school located in Medan City, North Sumatra. SMK Negeri 9 Medan has 5 majors with a total of 2077 students. Attendance management still uses conventional methods so it is necessary to conduct research related to the development of student attendance information systems. The methodology used in this research is problem identification, system requirement identification, data collection, system analysis and development. This study aims to facilitate the attendance process and attendance recapitulation. System development uses the Use Case Diagram model and Entity Relationship Diagram. The Use Case Diagram helps answer the functional requirements of the system desired by the school. While the Entity Relationship Diagram describes the database model. The model can be corrected to get the best results in database development.

Abstract

The research problem of this study is the urgent need for real-time parking availability information to assist drivers in quickly and accurately locating available parking spaces, aiming to improve upon the accuracy not achieved by previous studies. The objective of this research is to enhance the classification accuracy of parking spaces using a Convolutional Neural Network (CNN) model, specifically by integrating an effective normalizing function into the CNN architecture. The research method employed involves the application of four distinct normalizing functions to the EfficientParkingNet, a tailored CNN architecture designed for the precise classification of parking spaces. The results indicate that the EfficientParkingNet model, when equipped with the Group Normalization function, outperforms other models using Batch Normalization, Inter-Channel Local Response Normalization, and Intra-Channel Local Response Normalization in terms of classification accuracy. Furthermore, it surpasses other similar CNN models such as mAlexnet, you only look once (Yolo)+mobilenet, and CarNet in the same classification task. This demonstrates that EfficientParkingNet with Group Normalization significantly enhances parking space classification, thus providing drivers with more reliable and accurate parking availability information.

Abstract

Pembelajaran bahasa Inggris pada anak usia dini membutuhkan media yang interaktif, menarik, dan mudah dipahami. Metode pembelajaran konvensional kurang mampu mempertahankan perhatian anak, sehingga diperlukan aplikasi edukatif yang memadukan visual menarik, audio, dan animasi. Penelitian ini bertujuan untuk mengembangkan aplikasi Smart English Kids berbasis Android sebagai media pembelajaran bahasa Inggris interaktif untuk anak usia dini menggunakan metode Multimedia Development Life Cycle (MDLC). Aplikasi ini dibangun menggunakan Android Studio (Kotlin), memanfaatkan animasi Lottie, fitur Text-to-Speech (TTS) bilingual, serta kuis interaktif yang menghasilkan 10 soal acak dari 57 jumlah soal. Pada aplikasi ini membutuhkan sistem yang digunakan untuk menyimpan data dari pengguna. Untuk memenuhi hal tersebut maka digunakan Firebase. Firebase digunakan untuk penyimpanan skor online dan pelacakan status pengguna, sedangkan SharedPreferences digunakan sebagai penyimpanan lokal. Hasil pengujian black-box menunjukkan bahwa seluruh fungsi aplikasi berjalan sesuai kebutuhan, termasuk pengucapan suara otomatis, tampilan animasi, navigasi, dan penyimpanan skor. Aplikasi ini terbukti memberikan pengalaman belajar yang lebih menarik bagi anak usia dini serta membantu mempercepat pengenalan kosakata bahasa Inggris secara mandiri.

Abstract

PT. Perintis Perkasa merupakan perusahaan yang bergerak di bidang jasa servis mobil berkala. Dalam pelaksanaannya, proses pencatatan data servis, data pelanggan, data part, data pekerjaan, dan data perbaikan masih dilakukan secara manual, sehingga berpotensi menimbulkan kesalahan pencatatan, keterlambatan penyusunan laporan, serta kesulitan dalam pengelolaan data. Penelitian ini bertujuan untuk merancang dan membangun sistem informasi servis mobil berkala berbasis web yang mampu mengelola data secara terintegrasi dan terstruktur. Metode pengembangan sistem yang digunakan adalah metode waterfall, yang meliputi tahapan perumusan masalah, pengumpulan data, analisis sistem, perancangan, implementasi, dan pengujian. Sistem dikembangkan menggunakan bahasa pemrograman PHP native dengan database MySQL serta dijalankan pada web server XAMPP. Pengujian sistem dilakukan menggunakan metode Black Box Testing untuk memastikan setiap fungsi berjalan sesuai dengan kebutuhan pengguna. Hasil penelitian menunjukkan bahwa sistem informasi yang dibangun mampu mempercepat proses pencatatan servis, meningkatkan akurasi data, serta memudahkan penyajian laporan perbaikan secara real-time. Dengan demikian, sistem ini dapat menjadi solusi yang efektif dalam mendukung operasional dan meningkatkan kualitas pelayanan servis mobil di PT. Perintis Perkasa.

Abstract

The development of information technology has driven a transformation in healthcare service management, including in the management system of medical warehouse inventory in hospitals. Bhayangkara Hospital TK II Medan, as a referral hospital, has complex and ongoing medical logistics needs, requiring an effective and accurate inventory management system. However, inventory systems that are still manual or semi-computerized pose various problems, such as discrepancies between stock data and physical conditions, delays in information on item availability, difficulties in monitoring expiration dates, as well as the risk of stock shortages or overstocking. This study aims to design a web-based medical warehouse inventory system capable of managing data centrally and in real-time. The research methods used include system requirements analysis, system design, and web-based system implementation. The results of this study are expected to produce an inventory system that facilitates recording of incoming and outgoing goods, monitoring of stock and expiration dates, and the presentation of accurate reports. With this system, it is anticipated that the management of the medical warehouse inventory at Bhayangkara Hospital TK II Medan will become more effective and efficient and support improvements in healthcare service quality.

Abstract

The increasing digitalization of human resource management systems has led to the development of mobile applications that handle sensitive employee data, including financial information related to loan submissions. PT. Intikom Berlian Mustika's Stream Mobile application serves as an Employee Self-Service (ESS) platform that enables employees to submit loan requests directly through their mobile devices. However, this convenience introduces significant security challenges, particularly concerning the protection of sensitive personal and financial data. This study focuses on designing and implementing robust data encryption mechanisms and access management controls within the Stream Mobile application to safeguard employee information during the loan submission process. The research employs a qualitative approach combined with system development methodology, utilizing AES-256 encryption for data at rest and TLS 1.3 for data in transit, alongside Role-Based Access Control (RBAC) and OAuth 2.0 authentication. The implementation was evaluated through security testing, including penetration testing and vulnerability assessments. Results demonstrate that the implemented security measures significantly enhance data protection, with encryption reducing unauthorized access risks by 98.5% and access management preventing privilege escalation attempts. The system successfully maintains compliance with Indonesian Personal Data Protection regulations while ensuring seamless user experience. Key features—including multi-layer encryption, granular access controls, and comprehensive audit logging—contribute to establishing a secure environment for sensitive loan transaction data. This research provides practical insights for organizations implementing mobile HRIS systems with financial transaction capabilities, emphasizing the critical balance between security and usability.
