Perkembangan teknologi pendidikan memberikan peluang untuk mengembangkan media pembelajaran yang interaktif dan adaptif bagi siswa berkebutuhan khusus. Salah satu kemampuan dasar yang perlu dikuasai siswa tunagrahita adalah mengenal dan membaca jam analog. Namun, metode pembelajaran konvensional sering kali kurang menarik dan sulit dipahami oleh siswa. Penelitian ini bertujuan mengembangkan game edukasi adaptif pengenalan waktu berbasis algoritma Fuzzy Mamdani untuk meningkatkan pemahaman konsep waktu pada siswa tunagrahita. Game dikembangkan menggunakan metode Game Development Life Cycle (GDLC) dengan memanfaatkan Unity, Laravel, dan Firebase. Algoritma Fuzzy Mamdani digunakan untuk menentukan tingkat kesulitan soal secara adaptif berdasarkan ketepatan jawaban dan waktu respons pemain. Game dilengkapi modul pembelajaran, audio instruksi, evaluasi permainan, serta pemantauan hasil belajar siswa oleh guru. Pengujian dilakukan menggunakan Black Box Testing, White Box Testing, Usability Testing, serta pre-test dan post-test. Hasil penelitian menunjukkan bahwa seluruh fungsi sistem berjalan dengan baik, nilai usability mencapai 87,6% dengan kategori sangat baik, serta terjadi peningkatan pemahaman siswa sebesar 30% berdasarkan hasil pre-test dan post-test. Dengan demikian, game edukasi yang dikembangkan mampu mendukung pembelajaran pengenalan waktu yang lebih interaktif, adaptif, dan menarik bagi siswa tunagrahita.

Advancements in educational technology have created opportunities to develop interactive and adaptive learning media for students with special needs. One of the fundamental skills that students with intellectual disabilities need to acquire is the ability to recognize and read analog clocks. However, conventional teaching methods are often less engaging and difficult for students to understand. This study aims to develop an adaptive educational game for time recognition based on the Fuzzy Mamdani algorithm to improve students’ understanding of time concepts. The game was developed using the Game Development Life Cycle (GDLC) method and implemented using Unity, Laravel, and Firebase. The Fuzzy Mamdani algorithm was utilized to adaptively determine the level of question difficulty based on players’ performance, measured through answer accuracy and response time. The game includes learning modules, audio instructions, game-based evaluations, and a monitoring feature that allows teachers to track students’ learning outcomes. System evaluation was conducted using Black Box Testing, White Box Testing, Usability Testing, and pre-test and post-test assessments. The results indicate that all system functions operated properly, achieving a usability score of 87.6%, which falls into the excellent category. In addition, students’ understanding improved by 30% based on the pre-test and post-test results. Therefore, the developed educational game is capable of supporting a more interactive, adaptive, and engaging learning process for students with intellectual disabilities in understanding time concepts.
