The Baduy have a set of customary rules (pikukuh) and habits that are passed on to their offspring through oral language that can fade over the times. Important local wisdom is introduced to students as part of the learning process because it is close to everyday life, one of them through teaching materials. Therefore, the purpose of this research is to analyze the values of the local wisdom of the Baduy tribe to develop biology teaching materials in class X (ten) of High Schools. Data collection through interview, field observations and documentation is analyzed descriptively. The primary data in this study is the Pikukuh tribe in environmental management. The results showed eight pikukuh in environmental management could be appointed to develop teaching materials. Pikukuh contains local wisdom values including conservation values, sustainability values, the balance values of environmental care values, politeness values, discipline values, and cultural values. These values can be internalized into biology teaching materials in one of the basic competencies in class X of Senior High School, namely analyzing information/ data from various sources about the ecosystem and all interactions that take place in it and simulating interactions between components in an ecosystem.
