Desain Dan Implementasi Aplikasi Penghafal Al-Quran Android Di Rumah Tahfidz Rabbunalloh Surabaya
Get PDFIn general, some students also use a method called Tikrar, where the student repeats the verse. However, sometimes they're forgetting how many times it has been repeated. With Al-Quran Tikrar, there is a framework for memorizing Quran that can be found around the pages of the Quran. This helps to mark how many times the verse has been repeated using a ballpoint, pencil and such. But over time, the Quran would devreased its quality and condition, which causes the pages of the Quran seems dirty and damaged. The system works by making the memorizer or reciter be able to mark the number of times the verse has been repeated along with the level of fluency from "not yet memorized" to "mutqin" status, and the system can also store data on the quality of memorizing the Quran from day to day based on the number of verses memorized so that the supervisor or ustadz in the tahfidz Quran class can monitor the quality of the memorizer through the ustadz's dashboard. With Al-Quran Tikrar Android App, can memorize easily and integrated into Firebase so the repeated part can be recorded and not corrupted due to certain conditions.Pada umumnya beberapa penghafal Al-Quran juga menggunakan metode bernama Tikrar yaitu dimana penghafal tersebut mengulang berulang kali ayat tersebut terkadang lupa sudah berapa kali mengulang. Dengan adanya Al-Quran Tikrar terdapat framework hafalan Al-Quran yang terdapat di sekitar halaman Al-Quran untuk menandai ayat tersebut sudah berapa kali terulang menggunakan bolpoin atau semacamnya. Namun seiring berjalannya waktu, Al-Quran sebagai benda padat akan mengalami penyusutan kualitas dan keadaan Al-Quran tersebut yang menyebabkan halaman Al-Quran itu terkesan kotor dan rusak. Sistem berjalan dengan cara membuat penghafal dapat menandai sudah berapa kali ayat terulang disertai dengan tingkat kelancarannya dari belum hafal sampai mutqin, dan sistem juga bisa menyimpan data kualitas penghafal Al-Quran dari hari ke-hari berdasarkan jumlah ayat yang dihafal supaya pembimbing atau ustadz pada kelas tahfidz Quran tersebut dapat memantau kualitas penghafal tersebut melalui dashboard ustadz. Dengan adanya aplikasi android ini dapat menghafal mudah dan terintergrasi ke database
