Perancangan Sistem Perpustakaan Digital Berbasis Android dengan QR Code pada MTsN 2 Kota Bekasi

Counts differ because each database indexes a different set of publications. We treat OpenAlex as the canonical count; Google Scholar is not shown (no API, and crawling it violates its ToS).

Library at MTsN 2 Kota Bekasi is one of the supporting facilities for learning activities that serves as a source of information for both students and teachers. The library provides various collections of textbooks and supplementary books to support the teaching and learning process. Therefore, proper library management is essential to ensure that services are delivered effectively, efficiently, and in accordance with the information needs of the school community. However, library management at MTsN 2 Kota Bekasi is still carried out manually, including recording book data, member data, and borrowing and returning transactions using logbooks. This condition results in inefficient management processes, increases the risk of recording errors, and makes data retrieval and report generation more difficult for librarians. Therefore, this study aims to design and develop an Android-based digital library system utilizing QR Code technology. The development method employed is the Software Development Life Cycle (SDLC) using the Waterfall model, which consists of requirements analysis, system design, implementation, and testing. The system was designed using Unified Modeling Language (UML), implemented using Android Studio, PHP, JavaScript, Visual Studio Code, and XAMPP, and tested using the Black Box Testing method to ensure that the system functions according to the specified requirements. The results of this study indicate that the Android-based digital library system with QR Code technology improves the speed and accuracy of book borrowing and returning processes through automatic data identification. The system also facilitates the management of book, member, and transaction data, reduces recording errors, and generates more structured and easily accessible reports. Therefore, the developed system is expected to enhance the effectiveness and efficiency of library services at MTsN 2 Kota Bekasi.
