This study aims to develop a Student Worksheet (LKPD) on the biodiversity of medicinal plants of the Tidung Tribe for Grade X students at SMA Negeri 3 Kabupaten Nunukan Regency. The research method used is Research and Development (R&D) with the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The study population includes all Grade X students at SMA Negeri 3 Kabupaten Nunukan Regency, totaling 93 students, with a sample of 25 students. This study involves two types of tests: feasibility testing and practicality testing. The feasibility test is conducted by subject matter experts, media experts, language experts, and practitioners, while the practicality test is conducted by teachers and students. The research findings indicate that the feasibility test results are as follows: subject matter experts 93.5% (highly feasible), media experts 84.75% (feasible), language experts 96.5% (highly feasible), and practitioners 97.91% (highly feasible). Meanwhile, the practicality test results show that teachers rated the LKPD at 94% (highly practical), while students rated it at 87.8% (highly practical). Based on the analysis results, it can be concluded that the LKPD based on the local wisdom of the Tidung Tribe on the biodiversity of medicinal plants is highly feasible and highly practical for use in the learning process. The integration of local wisdom in the LKPD has been proven effective in increasing students' learning interest, understanding of biodiversity concepts, and awareness of local cultural preservation. This study is expected to serve as a reference for developing local wisdom-based learning materials in other subjects.
