<![CDATA[ This study aims to develop an Augmented Reality (AR)-based booklet as a learning medium for the topic of climate change and to examine its feasibility and effectiveness in seventh-grade junior high school Social Studies (IPS) learning. The research employed a Research and Development (R&D) method using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The study was conducted at SMPN 138 Jakarta. Data were collected through expert validation questionnaires, user response questionnaires, and learning achievement tests consisting of pre-tests and post-tests. The findings indicate that the developed AR-based booklet is feasible as a learning medium, as evidenced by the evaluations of media experts (75%, feasible), subject matter experts (78.3%, feasible), language experts (92.5%, highly feasible), Social Studies teachers (92.5%, highly feasible), and students (87.29%, highly feasible). The effectiveness of the learning media was demonstrated through a field test, which showed an increase in the average student learning achievement score from 76.4 to 92.2. The Wilcoxon signed-rank test revealed a statistically significant improvement (Sig. = 0.000), and the N-Gain score of 0.6909 fell within the moderate category. Therefore, the AR-based booklet is considered feasible and moderately effective for use appropriately in Social Studies learning on the topic of climate change. Abstrak Penelitian ini bertujuan untuk mengembangkan booklet berbasis Augmented Reality (AR) sebagai media pembelajaran pada materi perubahan iklim serta menguji kelayakan dan efektivitasnya dalam pembelajaran Ilmu Pengetahuan Sosial (IPS) kelas VII SMP. Penelitian ini menggunakan metode Research and Development (R&D) dengan model ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Penelitian dilaksanakan di SMPN 138 Jakarta. Data dikumpulkan melalui angket validasi ahli, angket respons pengguna, dan tes hasil belajar yang terdiri atas pre-test dan post-test. Hasil penelitian menunjukkan bahwa booklet berbasis AR yang dikembangkan layak digunakan sebagai media pembelajaran, sebagaimana ditunjukkan oleh penilaian ahli media (75%, layak), ahli materi (78,3%, layak), ahli bahasa (92,5%, sangat layak), guru IPS (92,5%, sangat layak), dan siswa (87,29%, sangat layak). Efektivitas media pembelajaran ditunjukkan melalui uji lapangan yang memperlihatkan peningkatan rata-rata nilai hasil belajar siswa dari 76,4 menjadi 92,2. Uji Wilcoxon signed-rank menunjukkan peningkatan yang signifikan secara statistik (Sig. = 0,000), dan skor N-Gain sebesar 0,6909 berada dalam kategori sedang. Oleh karena itu, booklet berbasis AR dinilai layak dan cukup efektif untuk digunakan secara tepat dalam pembelajaran IPS pada materi perubahan iklim.]]>
