No full textSMA Negeri 5 Madiun merupakan sekolah menengah atas yang berada di Kota Madiun. SMA ini memiliki fasilitas-fasilitas yang mendukung kegiatan belajar mengajar salah satunya adalah perpustakaan. Perpustakaan ini sudah memiliki sistem informasi berbasis web, namun masih memiliki beberapa permasalahan yaitu pengunjung baru tidak dapat melakukan pendaftaran anggota secara mandiri, minimnya informasi mengenai lokasi pasti buku pada rak bagi pengunjung baru bahkan anggota perpustakaan, dan anggota perpustakaan tidak berkesempatan meminjam buku yang diinginkan karena buku selalu didahului dipinjam oleh anggota lain. Maka, diperlukan penerapan teknologi mobile yang dapat diakses dimanapun dan kapanpun seperti M-Library (Mobile Library/Libraries). M-Library mempermudah proses peminjaman dengan adanya fitur booking peminjaman. Sehingga, berdasarkan permasalahan dan solusi yang ditemukan penulis mengembangkan aplikasi M-Library berbasis Android dengan menggunkan Dart Flutter.SMA Negeri 5 Madiun is a high school located in Madiun City. This high school has facilities that support teaching and learning activities, one of which is a library. This library already has a web-based information system but still has several problems such as new visitors being unable to register members independently, lack of information about the proper location of books on shelves for new visitors and even library members, and library members not having the opportunity to borrow books they want because books are always borrowed by other members. So, it is necessary to apply mobile technology that can be accessed anywhere and anytime such as M-Library (Mobile Library/Library). M-Library simplifies the lending process with a booking feature. So based on the problems and solutions found, the authors developed an Android-based M-Library application using Dart Flutter
