Abstract:
Media in biology learning is one of the means so that students understand the concept of biology in a broad sense. Most students still find it difficult to understand the concept of biology, especially in the Bryophytes subconcept because of the lack of local potential-based references that are directly related to student life. This encourages researchers to develop learning media in the form of booklets on the Bryophytes sub-concept Plantae. The purpose of this study was to describe the results of the validity of the Bryophytes booklet on the banks of the wisata alam Sungai Kembang as a high school learning medium for Grade X. This study used descriptive research methods and 4D model development methods. The validation test was carried out by experts consisting of 2 validators with an overall validity value of 84.21% with very valid criteria and suitable for use as a learning medium.
