PENGEMBANGAN ATLAS MORFOLOGI POHON JARAK PAGAR (JATROPHA CURCAS L.) SEBAGAI MEDIA PEMBELAJARAN BIOLOGI DI SMA/MA
This study focuses on the development of a morphological atlas of the Jarak Pagar tree (Jatropha curcas L.) that aligns with the Plantae (Spermatophyta) material found in the Independent Curriculum under the chapter on the Classification of Living Organisms. This atlas, featuring various captivating photos directly taken from field data, serves as an engaging learning medium to avoid monotony and enhance students' motivation and interest in learning. The study aims to determine the design, feasibility, and practicality of the Morphological Atlas of the Jarak Pagar Tree (Jatropha curcas L.) as a biology learning medium in high schools (SMA/MA). The research employs the research and development (R&D) method by Borg & Gall, utilizing the ADDIE model. The morphological study of the Jarak Pagar tree (Jatropha curcas L.) resulted in observations of five components: leaves, stems, flowers, fruits, seeds, and roots. The atlas developed from this research was evaluated by two (2) material experts, two (2) media experts, and two (2) biology teachers. A limited trial was conducted with 16 grade X students from SMA Negeri 1 Piyungan Bantul. Data on product feasibility and practicality were collected using a questionnaire. The results of validation and reliability tests by material experts were categorized as very high validity, with an average percentage of 87.5%, and very high reliability, with an average percentage of 87%. The assessments by media experts also fell into the very high validity category, with an average percentage of 88.3%, and very high reliability, with an average percentage of 93.8%. Practicality and reliability assessments by biology teachers were rated as very practical, with an average percentage of 92.5%, and very high reliability, with an average percentage of 86%. The students' evaluations were rated as very practical, with an average score of 0.603 (likely a typographical error), and very high reliability, with an average percentage of 87%. Therefore, the Morphological Atlas of the Jarak Pagar Tree can be considered highly feasible and practical as a biology learning medium in high schools (SMA/MA).
