Abstract

Jambu air (Syzygium aqueum) merupakan tumbuhan buah yang populer di Asia Tenggara. Tumbuhan ini memiliki nilai ekonomis dan budaya yang tinggi, sehingga penting untuk memahami penyebaran dan populasinya. Jambu air tumbuh subur di daerah tropis dengan curah hujan yang cukup dan suhu yang hangat. Penelitian ini bertujuan untuk mengkaji penyebaran dan populasi tumbuhan jambu air di suatu wilayah tertentu. Penelitian ini menggunakan penelitian jenis deskriptif kualitatif dengan pengumpulan data menggunakan metode survei dan eksperimental. Metode survei transek digunakan untuk mengumpulkan data tentang lokasi, kepadatan, dan distribusi populasi jambu air. Penelitian dilakukan di Kecamatan Naborambe, Kabupaten Deli Serdang. objek penelitiannya yaitu tumbuhan jambu air (Syzygium aqueum). Data dianalisis menggunakan teknik jelajah bebas. Hasil penelitian ini menunjukan bahwa jambu air (Syzygium aqueum) memiliki potensi yang sangat besar untuk dikembangkan di Kecamatan Namorambe, baik dari segi ekologis maupun ekonomi. Meskipun ada perbedaan dalam jumlah individu dan ukuran pohon antara Desa Jati kesuma dan Desa Jaba, kedua lokasi menunjukkan kondisi yang sehat dan mendukung pertumbuhan tanaman. Keberadaan jambu air memberikan manfaat ekologis, seperti penahan erosi tanah, serta manfaat ekonomi melalui produk olahan.

Abstract

Purpose of the study: This study aimed to develop a Teams Games Tournament (TGT)-based Biology Snakes and Ladders (ULTABI) learning media on the Human Musculoskeletal System and to evaluate its validity, practicality, and effectiveness in improving students’ critical thinking skills. Methodology: The study employed a 4-D development model (Define, Design, Develop, and Disseminate). The research participants consisted of 20 eleventh-grade science students at Al-Wardah Educational Foundation Madrasah Aliyah. The research instruments included a needs-analysis questionnaire, media and materials expert validation sheets, teacher and student response questionnaires, and a critical-thinking skills test based on Facione's critical-thinking indicators. The data were analyzed descriptively using percentage analysis and the Normalized Gain (N-Gain) test. Main Findings: The results showed that the ULTABI learning media achieved a very high level of validity, with scores of 93.18% from media experts and 86.90% from material experts. The media was also rated as very practical by both teachers (97.70%) and students (88.70%). The effectiveness test revealed a significant improvement in students’ critical thinking skills, with the average score increasing from 39.65 on the pre-test to 91.30 on the post-test, resulting in an N-Gain score of 0.845, which falls into the high category. Among the critical thinking indicators, interpretation achieved the highest score, whereas evaluation showed the lowest achievement. Novelty/Originality of this study: The Teams Games Tournament (TGT)-based ULTABI learning media is proven to be valid, practical, and effective in enhancing students’ critical thinking skills on the topic of the Human Musculoskeletal System.
