The readability booklet by students got a percentage of 98,21% with “very good” criteria. The result of cognitive learning outcomes shows that the classical completeness reached 100% and based on the N-gain test, 94,44% of students got "medium to high" criteria. Psychomotor learning outcomes were obtained from exploration activities, 88,89% of students got "good to excellent" criteria and 11,11% of students got "sufficient" criteria. Affective learning outcomes were obtained from a questionnaire of conservation attitudes, 36,11% of students got "good to excellent" criteria, 47,22% of students got "sufficient" criteria, and 16,67% of students got "poor" criteria. The conclusion of this research is the development of biodiversity booklet in Demak Regency as a supplement of teaching materials is proven to be feasible to use, well readable, and effective to increase learning outcomes of students in class X Senior High School on biodiversity material.
