Institutional Repository UIN Sunan Kalijaga YogyakartaKAJIAN MORFOLOGI DAN FENOLOGI PEMBUNGAAN Passiflora vitifolia SERTA PENGEMBANGAN ATLASNYA SEBAGAI MEDIA BELAJAR BIOLOGI KELAS XI SMA/MANIM.: 22104070009Sofia RamadhaniauthorThis study aimed to describe the morphological characteristics and flowering phenology of Passiflora vitifolia, develop an atlas of its morphology and flowering phenology as a biology learning medium for the topic of plant growth and development, determine the feasibility of the developed atlas based on evaluations by material and media experts, and determine its practicality based on assessments by a biology teacher and students' responses. The study consisted of two stages. The first stage employed a qualitative descriptive approach to examine the morphological characteristics and flowering phenology of Passiflora vitifolia through observation, documentation, literature review, and descriptive analysis. The observation of flower morphology and flowering phenology was conducted because Passiflora vitifolia flowers undergo structural changes throughout the flowering process, representing the growth and development of plant reproductive organs and making them relevant as a learning resource. The second stage employed a Research and Development (R&D) approach using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model, which was limited to the Development stage. The feasibility of the atlas was evaluated by material and media experts, while its practicality was assessed by a biology teacher and eleventh-grade senior high school students. The results showed that Passiflora vitifolia is a perfect (hermaphroditic) flower that reproduces sexually and possesses morphological structures consisting of bracts, sepals, petals, corona, stamens, pistil, ovary, receptacle, and pedicel. Its flowering phenology consists of five stages: initial initiation (the emergence of flower primordia), advanced initiation (the development of flower primordia), pre-anthesis (before flower opening), anthesis (full bloom), and post-anthesis (the onset of flower senescence). The stages from initial initiation to pre-anthesis represent the process of plant growth, which is characterized by an increase in flower size, whereas the anthesis and post-anthesis stages represent the process of plant development, characterized by changes in floral structure leading to senescence. The developed atlas was rated Very Good based on the validation results of the material and media experts and the practicality assessment conducted by the biology teacher and students. Therefore, the atlas of the morphology and flowering phenology of Passiflora vitifolia is considered feasible and practical as a biology learning medium for the topic of plant growth and development.371.33 Media Pembelajaran2026-07-22UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
