<![CDATA[This study was motivated by the low understanding of circle concepts among students at SMA Muhammadiyah Ahmad Dahlan Metro. Based on daily test results, the students’ average score was only 35%, far below the minimum achievement criterion of 75. This condition was attributed to the use of printed textbooks that were less engaging and did not clearly and systematically present problem-solving steps. In addition, mathematics instruction had not fully integrated Islamic values, although the school’s vision emphasizes Islamic character education. Therefore, this study aimed to develop an Android-based learning application using a Problem-Based Learning (PBL) approach oriented toward Islamic values. The development process employed the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation. Data were collected through validation and practicality questionnaires validated by six experts: two material experts, two media experts, and two Islamic values experts. A practicality test involved 10 eleventh-grade students. The validation results reached 89%, categorized as highly valid, while practicality reached 87%, categorized as highly practical. The application was visually engaging, easy to use, and capable of integrating faith, morality, and discipline into mathematics learning. Penelitian ini dilatarbelakangi oleh rendahnya pemahaman peserta didik SMA Muhammadiyah Ahmad Dahlan Metro terhadap materi lingkaran. Berdasarkan hasil ulangan harian, rata-rata skor peserta didik hanya mencapai 35%, jauh di bawah KKTP sebesar 75. Kondisi tersebut disebabkan oleh penggunaan buku cetak yang kurang menarik dan belum menyajikan langkah penyelesaian soal secara jelas serta sistematis. Selain itu, pembelajaran matematika belum sepenuhnya mengintegrasikan nilai-nilai Islam, meskipun sekolah memiliki visi menanamkan pendidikan berkarakter islami. Penelitian ini bertujuan mengembangkan aplikasi pembelajaran berbasis Android dengan pendekatan Problem-Based Learning (PBL) yang berorientasi pada nilai-nilai Islam. Pengembangan menggunakan model ADDIE yang meliputi Analyze, Design, Development, Implementation, dan Evaluation. Instrumen penelitian berupa angket validasi dan kepraktisan yang divalidasi oleh enam ahli, terdiri atas dua ahli materi, dua ahli media, dan dua ahli nilai-nilai Islam. Uji kepraktisan melibatkan 10 peserta didik kelas XI. Hasil validasi memperoleh 89% dengan kategori sangat valid, sedangkan kepraktisan mencapai 87% dengan kategori sangat praktis. Aplikasi dinilai menarik, mudah digunakan, dan mampu mengintegrasikan nilai keimanan, akhlak, serta kedisiplinan dalam pembelajaran matematika.]]>
