Haw), develop a wijaya kusuma flowering phenology encyclopedia as a source of learning biology, determine the feasibility of the encyclopedia as a source of learning biology and to determine the response of educators and students to the wijaya kusuma flowering phenology encyclopedia as a source of learning biology. This research and development uses a descriptive qualitative method which is then developed into a product in the form of an encyclopedia with the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation) which is limited only to the development stage. The product feasibility test was carried out using an instrument in the form of a questionnaire based on the linkert scale. Based on the research results, the flowering phenology of Wijaya Kusuma (Epiphyllum oxypetalum (DC.) Haw) takes about 19 days for the buds to turn into flower anthesis which then lasts for 2 days until the flower blooms on the 23rd day. During the flower blooming period, the petaloids and sepaloids start to open at 18.00 WIB to 00.00 WIB, then the flowers start to wilt at 05.00 WIB to 12.00 WIB. On the 26th day, it was recorded that at 05.00 WIB the flowers were dry and at 08.00 WIB the flower stalks had broken and fallen along with the flowers attached to the stalks. The product feasibility assessment was carried out by four validators, namely, material experts, media experts, peer reviewers, and biology teachers of MAN 2 Sleman, then tested on a limited basis to 15 class XII students of MAN 2 Sleman. The average result of the total encyclopedia feasibility value was 94.8% with a very good feasibility value. Based on the assessment, it can be concluded that the Encyclopedia of Biology of Phenology of Flowering Plants by Wijaya Kusuma (Epiphyllum oxypetalum (DC.) Haw) for Senior High School/Vocational High School Grade XII is very suitable for use as a source of learning biology for Senior High School/Vocational High School level. %Z Mike Dewi Kurniasih, M.Pd.
