Abstract

Penelitian ini mengevaluasi dampak program Kafe Baca Agrowisata di Desa Hessa Air Genting dalam meningkatkan minat baca dan literasi masyarakat. Melalui pendekatan kualitatif, penelitian ini menganalisis hal-hal yang menyokong, juga memperlambat kegiatan, beserta kontribusinya terhadap pembangunan desa. Hasil penelitian menunjukkan bahwa program ini berhasil meningkatkan akses terhadap bahan bacaan, memperkaya pengetahuan masyarakat, dan memperkuat rasa kebersamaan. Pendekatan kolaboratif, relevansi bahan bacaan, dan dukungan masyarakat menjadi kunci keberhasilan program. Namun, penelitian ini juga mengidentifikasi beberapa tantangan yang perlu ditangani, seperti sumber daya yang terbatas dan perubahan minat baca. Penelitian ini menyarankan pentingnya diversifikasi program, kerja sama dengan berbagai pihak, dan pemanfaatan teknologi untuk memastikan keberlanjutan serta perluasan dampak program. Program Kafe Baca Agrowisata dapat menjadi model bagi upaya peningkatan literasi di daerah pedesaan lainnya.

Abstract

This study aims to determine the effectiveness of the Problem-Based Learning (PBL) model in improving students’ mathematical thinking skills on the Exponent topic among Grade X students at SMA Negeri 1 Simpang Empat in the 2024/2025 academic year. This quasi-experimental research employed a pre-test–post-test control group design with two classes: an experimental class receiving PBL instruction and a control class taught through conventional learning. The average pre-test scores of the experimental and control classes were 69.11 and 66, respectively. After the learning intervention, the average post-test score of the experimental class increased significantly to 84.61, while the control class achieved only 57.37. Statistical analysis using the t-test revealed that the calculated t-value (t_hitung = 4.42) exceeded the critical t-value (t_tabel = 1.67), indicating a significant difference between the two groups. These findings demonstrate that the PBL model has a positive and significant effect on enhancing students’ mathematical thinking skills in Exponent material. Therefore, PBL can be considered an effective alternative instructional approach for mathematics learning at the senior high school level.
