Abstract

Penelitian ini bertujuan untuk mengidentifikasi pengaruh aktivitas manusia terhadap komunitas tumbuhan di Jalan Rambutan, Dusun 2 Jatikesuma, Namorambe, Sumatera Utara. Aktivitas manusia, seperti pertanian, pembangunan infrastruktur, dan eksploitasi sumber daya alam, telah memberikan dampak signifikan terhadap struktur dan komposisi komunitas tumbuhan di daerah tersebut. Metode yang digunakan dalam penelitian ini adalah kualitatif, yang meliputi observasi lapangan dan wawancara mendalam dengan masyarakat lokal untuk menggali pengetahuan tradisional serta persepsi mereka mengenai perubahan lingkungan. Hasil penelitian menunjukkan bahwa penggunaan pestisida dan herbisida dalam praktik pertanian modern dapat mengurangi keanekaragaman spesies tumbuhan dan menyebabkan pencemaran lingkungan. Keterlibatan masyarakat lokal dalam konservasi dan pengelolaan sumber daya alam sangat penting untuk memastikan keberlanjutan ekosistem. Penelitian ini diharapkan dapat memberikan wawasan yang berguna bagi pengambil kebijakan dan masyarakat dalam upaya melestarikan keanekaragaman hayati dan mengelola sumber daya tumbuhan secara berkelanjutan.

Abstract

Purpose of the study: This study aims to develop Science Literacy-Based Smart Card Media on the nervous system material for 11th-grade science students and to test its validity, practicality, and effectiveness in improving students’ science literacy skills. Methodology: The study uses a Research and Development approach based on the 4-D model, which includes the stages of define, design, develop, and disseminate. The research subjects were 35 11th-grade science students at Budisatrya Private High School, Medan. Research instruments included interview guidelines, expert-validation questionnaires, teacher and student response questionnaires, and pretests and posttests. The data were analyzed descriptively using validity percentages, practicality, N-Gain, and a paired-samples t-test. Main Findings: The research results show that the developed media received a media expert validation score of 96.42% and a material expert score of 89.06%, both of which fall into the very valid category. Practicality tests showed student responses of 95% and teacher responses of 98.14%, both categorized as very practical. Effectiveness tests showed an increase in average scores from 46 on the pretest to 90 on the posttest, with an N-Gain score of 0.81 (80.88%), categorized as high. Novelty/Originality of this study: The novelty of this research lies in integrating PISA science literacy indicators into Smart Card media by presenting scientific phenomena, contextual case studies, data interpretation, and problem-solving activities on the nervous system. Science Literacy-Based Smart Card Media is declared valid, practical, and effective, making it suitable for use as an alternative Biology learning media to support the strengthening of students’ science literacy.
