This research aims to analyze students' difficulties in solving mathematical problems on linear programming material using qualitative descriptive methods based on the Polya heuristic. This research involved students with high, medium, and low abilities through analysis of written tests and student interviews. Data was collected from 30 class XI students at SMA X using specially designed written tests and in-depth interviews. Data analysis was carried out using thematic analysis techniques. The research results show that students with high abilities do not experience difficulties in working on contextual problems in linear programming material. Students with moderate abilities experience difficulty in determining the sign of inequality and the set of solution areas. Meanwhile, students with low abilities experience difficulties in various aspects, including understanding basic concepts and applying problem-solving steps. Specific examples of difficulties experienced include errors in drawing graphs and determining intersection points. As a recommendation, teachers are advised to introduce and explain problem-solving according to Polya's heuristics more concretely and systematically. For example, using Polya steps in varied practice sessions and providing specific feedback at each stage of problem-solving. In this way, students' understanding of linear programming material can be significantly improved.

The integration of augmented reality (AR) technology into education has gained attention as an innovative tool to enhance students' learning experiences, particularly for abstract concepts such as chemical bonding. E-modules that incorporate AR can provide three-dimensional visualizations, making complex topics more accessible and engaging. This study aims to develop and validate practical e-modules using AR technology to enhance students' spatial intelligence while incorporating local wisdom from Padangsidimpuan. The research follows a Research and Development (R&D) approach using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model and a pretest-posttest control group design. Data were collected from three high schools in Padangsidimpuan using simple random sampling. Instruments included validation sheets (for material, media, and language), observation, user response questionnaires, and pretest-posttest tests to assess students' spatial intelligence. The e-module achieved high validation scores: 0.9 (material), 0.8 (media), and 0.9 (language). Student response rates were 80% (feasibility), 85% (AR usage), and 83.2% (language). Teachers provided an average response score of 88.6, indicating high practicality. The spatial intelligence assessment across the three schools yielded an average score of 0.85 in the high category. The AR-based e-modules effectively improve students' spatial intelligence by visualizing abstract chemical bonding concepts in 3D. This innovation contributes to enhancing chemistry education and preserving local wisdom in Padangsidimpuan, offering a model for future educational advancements.

Pertanian berkelanjutan menghadapi tantangan signifikan dari meningkatnya ancaman hama, terutama di wilayah seperti Arab Saudi dan Indonesia. Artikel ini mengkaji strategi inovatif dalam pengendalian hama melalui integrasi teknologi canggih, yaitu kecerdasan buatan (AI) dan drone, untuk mengurangi ketergantungan pada pestisida kimia dan memperkuat ketahanan tanaman. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis tren dan efektivitas pengendalian hama menggunakan pendekatan teknologi dari tahun 2020 hingga 2025. Metode yang digunakan dalam penelitian ini adalah Tinjauan Literatur Sistematis (SLR) yang mengumpulkan dan mengevaluasi studi peer-review terkait pengendalian hama, AI, dan drone. Data dianalisis menggunakan teknik analisis tematik untuk mengungkap informasi mendalam mengenai aplikasi dan hasil integrasi teknologi ini. Hasil analisis menunjukkan bahwa penggunaan AI dan drone dalam pengendalian hama adalah hal yang baik, dengan beberapa penelitian menunjukkan pengurangan penggunaan bahan kimia hingga 40% dan peningkatan hasil panen hingga 20%. Teknologi AI memungkinkan deteksi hama dan prediksi serangan hama yang lebih akurat, sementara drone secara efektif mendistribusikan agen pengendalian hayati dan memantau ladang secara real time. Kesimpulannya, integrasi AI dan teknologi drone meningkatkan efektivitas pengendalian hama dan berkontribusi pada pengembangan pertanian yang lebih ramah lingkungan dan berkelanjutan. Penerapan teknologi ini diharapkan dapat menjadi model bagi negara-negara lain yang menghadapi tantangan pengendalian hama serupa.
