PENGEMBANGAN LKPD BERBASIS MIND MAPPING MATERI EKOSISTEM UNTUK MENINGKATKAN HASIl BELAJAR SISWA KELAS X SMA

THE DEVELOPMENT OF WORKSHEET BASED ON MIND MAPPING IN ECOSYSTEM MATERIALS TO IMPROVE THE STUDENT OUTCOMES OF CLASS X HIGH SCHOOL STUDENT

Ekosistem memiliki cakupan materi luas dan konsep yang nyata, sehingga sangat diharapkan peserta didik mampu menemukan konsep belajarnya sendiri. Upaya yang dilakukan untuk meningkatkan hasil belajar siswa dapat dilakukan dengan menggunakan bahan ajar sesuai dengan tuntutan kurikulum merdeka yang mana pembelajaran harus berpusat pada siswa (Student Centered). Penelitian ini bertujuan menghasilkan LKPD berbasis mind mapping materi ekosistem yang valid, praktis, dan efektif. Penelitian ini menggunakan model pengembangan 4D (Define, Design, Development dan Disseminate). Validitas LKPD diukur menggunakan instrumen validasi berdasarkan aspek penyajian, isi dan kebahasaan. Kepraktisan LKPD diukur menggunakan instrumen observasi keterlaksanaan, respons positif guru dan siswa. Keefektifan LKPD diukur menggunakan nilai tes yang mendapat nilai sedang hingga tinggi. LKPD dikategorikan valid apabila mencapai kevalidan sebesar ≥61%, praktis apabila keterlaksanaan dan respons mencapai kepraktisan ≥61%, keefektifan apabila persentase ketuntasan hasil belajar ≥71%. Penelitian ini menghasilkan LKPD untuk guru dan peserta didik dengan validitas LKPD sebesar 3,9 dengan validitasnya sebesar 97,8% (sangat valid). Hasil kepraktisan LKPD dari keterlaksanaan pembelajaran memperoleh kepraktisan sebesar 97,7% (sangat praktis) dan respons guru dan siswa memperoleh respons sebesar 95,8% (sangat positif). LKPD berbasis mind mapping efektif karena memperoleh nilai N-Gain sebesar 0,72 (tinggi) dan ketuntasan hasil belajar 100% (sangat efektif).  LKPD berbasis mind mapping dinyatakan layak digunakan berdasarkan aspek validitas, kepraktisan dan keefektifan untuk pembelajaran biologi kelas X SMA.

Ecosystems have broad material coverage and real concepts, so it is expected that students are able to find their own learning concepts. Efforts to improve student learning outcomes can be made by using teaching materials in accordance with the demands of the independent curriculum, where learning must be student-centered. This research aims to produce LKPD based on mind mapping ecosystem material that is valid, practical, and effective. This research uses the 4D development model (define, design, develop, and disseminate). The validity of LKPD is measured using a validation instrument based on aspects of presentation, content, and language. The practicality of LKPD was measured using the implementation observation instrument and the positive responses of teachers and students. The effectiveness of LKPD is measured using test scores that get medium to high scores. LKPD is categorized as valid if it achieves validity of ≥61%, practical if the implementation and response achieve practicality ≥61%, effective if the percentage of learning outcomes completeness is ≥71%. This study produced LKPD for teachers and students, with the validity of LKPD amounting to 3.9 and a validity of 97.8% (very valid). The results of the practicality of LKPD from the implementation of learning obtained a practicality of 97.7% (very practical), and the responses of teachers and students obtained a response of  95.8% (very positive). The mindmapping-based LKPD is effective because it obtained an N-Gain value of 0.72 (high) and 100% learning completeness (very effective). LKPD based on mind mapping is declared feasible to use based on aspects of validity, practicality, and effectiveness for learning biology class X SMA.
