EKSPLORASI ANATOMI DAN MORFOLOGI PTERIDOPHYTA DI LINGKUNGAN SMA KOLOMBO DAN PENGEMBANGANNYA SEBAGAI MEDIA PEMBELAJARAN KELAS X SMA / MANIM.: 20104070044Latifah Ainur RohmahauthorBiology instruction regarding the Plantae kingdom specifically Pteridophyta for Grade X students at SMA Kolombo faces challenges due to a lack of visual and contextual learning media and the underutilization of the surrounding environment as a learning resource. This study aims to develop a Pteridophyta morphology and anatomy atlas based on the environment surrounding SMA Kolombo, assess the product's feasibility and the responses of teachers and students, and identify the Pteridophyta species found within the school grounds. The study employs the Research and Development (R&D) method using the ADDIE model, limited to the analysis, design, and development stages. Data were collected through observation, interviews, documentation, and questionnaires involving subject matter experts, media experts, reviewers, teachers, and students. Data were analyzed using descriptive quantitative methods based on feasibility percentages. The results indicate that the developed atlas contains information on the morphology, anatomy, classification, and documentation of Pteridophyta found in the SMA Kolombo environment. Validation results showed feasibility scores of 96.75% from subject matter experts, 90.09% from media experts, and 85.08% from reviewers, all falling into the "highly feasible" category. Teacher and student responses yielded positive ratings of 90% and 95.3%, respectively, placing them in the "excellent" category. Based on these findings, the Pteridophyta morphology and anatomy atlas based on the SMA Kolombo environment is deemed suitable for use as a learning resource for Grade X Biology.371.33 Media Pembelajaran2026-07-15UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
