<![CDATA[Abstract: Based on observations and interviews with biology teachers in grade X at PGRI Pulang Pisau High School, it was found that the learning resources used were still limited to textbooks that contained brief learning activities and practical work. The available student worksheets did not cover important components such as identity, basic competencies, and theoretical foundations, and were uninteresting due to the lack of variety in the material and questions. This condition has an impact on the low motivation and involvement of students in learning. To overcome this problem, integrated local Dayak wisdom LKPD based on CrosswordLabs was developed to make learning more contextual and interactive. This study aims to develop LKPD, its validity, and practicality. The development method used the modified 4D model (Define, Design, Develop, Disseminate) up to the Develop stage. The results showed that the worksheets fulfilled important learning elements such as identity, basic competencies, objectives, material, learning activities, and CrosswordLabs-based exercises. The overall validity test resulted in a percentage score of 83.00%, which is considered valid. The practicality test showed a very practical category with a response rate of 85.35% from students and 89.00% from teachers. Thus, this LKPD is feasible and very practical for use in biology learning.
