Abstract

Seventy-two percent of the Muslim population in Indonesia is illiterate in Arabic script, thus requiring early childhood education. Young children often struggle to directly learn Arabic script, necessitating the role of instructors. However, most instructors in madrasahs do not teach Arabic script intensively, prompting the need for interactive and engaging learning media for children. Therefore, the development of an Android application for teaching Arabic script to young children is crucial. By employing the Rapid Application Development (RAD) method, an Android application can be developed, incorporating gamification for interactive learning and the AI Life Cycle for developing a 3D Arabic script object detection model useful for automatic correction systems. The AI model is developed using SSD MobileNet v2 FPN Lite 640x640. Sixteen trials are conducted for separate letter modeling and two for connected letters. The separate letter modeling yields the best result in the 8th trial with a total loss of 0.182882 out of 1, using parameters of 16 batch size, 30,000 num steps, and checkpoint from the 7th trial. Connected letter modeling yields the best result in the 2nd trial with parameters of 8 batch size, 14,000 num steps, and checkpoint from the 1st trial. The output is an offline Android application integrating gamification and AI technology, featuring two categories of questions, each with 20 items.

Abstract

The Gereja Kristen Jawa (GKJ) Semarang Timur is located in the East Semarang area, with approximately 350 registered members, though average weekly worship attendance is only around 100 people. Member data is still recorded manually in printed books, while information on church activities, offerings, finances, inventory, and other updates is shared through WhatsApp groups or the printed Church Bulletin, which is only distributed during Sunday services. This limits access for members who are absent and makes data recording and retrieval inefficient. This study aims to design and develop a web-based information system to facilitate member data management, dissemination of worship information, and provide a platform for members to evaluate church services. The system includes features for member records (including transfers and deaths), event schedule management, evaluation forms, and regularly updated announcements. The system design follows the waterfall method, with data collected through observation, interviews, and literature review. Primary data was obtained from the GKJ Semarang Timur Church Council and administrative staff, while secondary data came from journals and books related to web-based information system development. The resulting website features a simple, user-friendly interface tailored to the church administration’s needs. The implementation of this system is expected to improve data search efficiency, expand the reach of church information, and serve as an effective communication medium between the church and its members. its congregation.
