Abstract

This study aims to analyze students' learning difficulties in understanding the human regulatory system material in eleventh-grade students at Kartika 1-4 Private High School, Pematangsiantar. The population in this study was all eleventh-grade students, consisting of three classes, totaling 150 students. Sampling was conducted using cluster random sampling, with a 20% sample size, with 10 students from each class, totaling 30 students. The method used in this study was descriptive. Student learning difficulties were analyzed using instruments in the form of multiple choice tests and closed-ended questionnaires with a Likert scale. The results of the test data analysis showed that the average percentage of students' learning difficulties was 75.65%, categorized as weak, meaning students had difficulty understanding the human regulatory system material. The questionnaire results indicated that internal factors influencing student learning difficulties included interest and motivation (67.08%) interpreted as weak, and readiness and attention (63.33%) interpreted as weak. Meanwhile, external factors, including the family environment (75% of which was interpreted as weak), the school environment (71.94% of which was interpreted as weak), and the community environment (65.83% of which was interpreted as weak), concluded that aspects with weak interpretations had no effect on student learning difficulties. Furthermore, the time allocation aspect (39.33% of which was interpreted as strong) significantly influenced student learning difficulties. The average percentage of factors influencing learning difficulties was 63.75%.

Abstract

Indonesia dikenal sebagai negara “megabiodiversity” dengan keanekaragaman jenis tanaman dan hewan yang sangat tinggi. Indonesia memiliki sekitar 80% dari total spesies tumbuhan berkhasiat obat yang ada di dunia. Upaya pemanfaatan tumbuhan sebagai obat tidak hanya dilakukan oleh masyarakat umum, tetapi juga dilakukan oleh pemerintah. Pengobatan tradisional berasal dari bahan alami yang lebih murah dengan bahan baku yang mudah didapatkan. Di sisi lain, kearifan lokal pada komunitas tertentu memungkinkan masyarakat memanfaatkan obat tradisional. Potensi tanaman obat yang terdapat di sekitar Taman Nasional Gunung Leuser tepatnya di Desa Batu Jongjong, Kecamatan Bahorok, Kabupaten Langkat. Potensi tanaman obat yang terdapat di sekitar Taman Nasional Gunung Leuser tepatnya di Desa Batu Jongjong, Kecamatan Bahorok, Kabupaten Langkat sangat banyak. Oleh sebab itu perlu dilakukan pemberdayaan masyarakat terkait pemanfaatan lahan sebagai upaya pendidikan konservasi masyarakat sekitar yang berwawasan konservasi. Salah satu cara pemanfaatan lahan adalah dengan taman TOGA. Pengabdian kepada masyarakat ini bertujuan untuk memberdayakan masyarakat sebagai sarana pendidikan konservasi. Kegiatan pengabdian Masyarakat ini dikembangkan menjadi kegiatan yang sinergis sehingga diharapkan dampaknya akan lebih optimal terhadap masayarakat.
