Abstract

Teaching materials in learning activities have an important meaning so that the learning process is easier and more effective. Local potential can be used as a source of learning to look at phenomena, events, and problems in an area or what is also called contextual learning. The handout is one of the teaching materials that is concise and makes it easier for students to understand learning. The research method used was to analyze the results of research on proboscis monkey (Nasalis larvatus) on Curiak Island by Zainudin and Rezeki, to be used as material for the development of proboscis monkey (Nasalis larvatus) handouts on Curiak Island with the Tessmer development model which was limited to the expert stage review (Expert Test). The validation test was carried out with experts consisting of 3 (three) validators with an overall validity value of 90.6% (very valid and fit for use without revision). Its validity is shown by the average assessment on the feasibility aspect of the content of 85.07% (very valid), the assessment of the feasibility of serving 91.25% (very valid), and the assessment of the language aspect of 87.14% (very valid).Abstrak Bahan ajar pada kegiatan pembelajaran memiliki arti penting, agar proses pembelajaran lebih mudah dan lebih efektif.
