REDESIGN USER INTERFACE APLIKASI NGAJI.AI BERBASIS MOBILE MENGGUNAKAN METODE DESIGN THINKING

Ngaji.AI is a mobile-based application that makes it possible to learn the Koran very flexibly, wherever and whenever we can use it to learn the Koran. This application is supported by artificial intelligence (AI) which provides direct and accurate assessments of how to recite Al-Quran verses properly and correctly and this application has been released on the Google Playstore platform and has been downloaded by more than 5 thousand. The Ngaji.AI application is faced with a crucial challenge, after direct observation of children and through the results of previous user input on Playstore, most of the input from users states that it needs to improve the User Interface (UI) design to make it easier to operate for children. The application of the Design Thinking method is an approach that prioritizes creativity and deep understanding of users and the problems they face and is indeed suitable for developing UI/UX of an application. Testing using the System Usability Scale (SUS) in the first test before the redesign got an average score of 50.25 and after the redesign got a significant score of 83.75. This reflects a significant increase in the level of satisfaction and ease for children in learning to recite the Koran on the Ngaji.Ai application.
