Institutional Repository UIN Sunan Kalijaga YogyakartaEKSPLORASI KEANEKARAGAMAN TANAMAN SALAK DI JOY’S FARM DAN PENGEMBANGAN ENSIKLOPEDIANYA PADA MATERI PLANTAE UNTUK SISWA KELAS X SMA/MANIM.: 22104070011Wening KumalasariauthorBiology learning on the Plantae topic at SMA Negeri 1 Turi still faces challenges, as students experience difficulties in describing plant structures and morphological characteristics due to the use of general learning resources, the predominance of lecture and presentation methods, and the limited utilization of local potential as learning media. Meanwhile, Joy's Farm in Donokerto, Turi, Sleman Regency possesses diverse salak varieties that have the potential to be utilized as contextual learning resources. This study aimed to develop a local potential-based salak encyclopedia using Joy's Farm as a Biology learning medium for the Plantae topic for Grade X senior high school students and to determine the feasibility of the developed product. This study employed a Research and Development (R&D) approach using the ADDIE model, which was limited to the Analysis, Design, and Development stages. Data were collected through observation, interviews, documentation, and questionnaires. Product validation was conducted by one subject matter expert, one media expert, and one Biology teacher, while a limited trial was carried out involving 15 Grade X students of SMA Negeri 1 Turi. The data were analyzed using descriptive quantitative and qualitative techniques. The results showed that Joy's Farm cultivates three salak varieties, namely Pondoh, Gading, and Madu, all of which belong to the species Salacca zalacca (Gaertn.) Voss. These varieties exhibit morphological differences, particularly in fruit skin color, fruit flesh color and texture, fruit taste, and thorn characteristics on the leaf sheath, indicating genetic-level biodiversity. The validation results showed that the encyclopedia obtained a feasibility score of 98% from the subject matter expert (very feasible), 97% from the media expert (very feasible), and 73% from the Biology teacher (feasible). Furthermore, students' responses reached 90%, categorized as very good. Based on these findings, the local potential-based salak encyclopedia developed from Joy's Farm is considered feasible for use as a Biology learning medium for the Plantae topic for Grade X senior high school students and received very positive responses from the students.570.7 Pendidikan Biologi2026-08-11UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
