PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK ELEKTRONIK BERBASIS PROBLEM BASED LEARNING PADA MATERI PERUBAHAN LINGKUNGAN UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH PESERTA DIDIK KELAS X SMA

THE DEVELOPMENT OF ELECTRONIC STUDENT WORKSHEETS BASED ON PROBLEM BASED LEARNING ON ENVIRONMENTAL CHANGE MATERIAL TO IMPROVE THE PROBLEM SOLVING SKILLS OF CLASS X HIGH SCHOOL STUDENTS

Kurikulum merdeka belajar adalah kurikulum terbaru yang diterapkan untuk mewujudkan pembelajaran yang bersifat student centered dan mengarah pada pemecahan masalah yang menjadi tuntutan skill pada abad 21. Problem Based Learning merupakan model pembelajaran yang cocok diterapkan di kurikulum merdeka belajar materi perubahan lingkungan. Model PBL yang diimplementasikan dalam bentuk e-LKPD mampu merangsang keaktifan peserta didik dalam pembelajaran serta menjadi terbiasa memecahkan permasalahan yang ada. Penelitian ini memiliki tujuan untuk menghasilkan e-LKPD berbasis PBL yang layak pada materi perubahan lingkungan untuk meningkatkan kemampuan pemecahan masalah peserta didik kelas X SMA berdasarkan aspek kevalidan, kepraktisan, dan keefektifan. Penelitian ini merupakan jenis penelitian pengembangan dengan mengacu pada model ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Metode pengumpulan data dilakukan dengan validasi oleh validator yang terdiri dari dosen ahli materi, ahli media, dan guru biologi SMA untuk mendapatkan data validitas, observasi oleh observer untuk mendapatkan data kepraktisan, pemberian tes dan pemberian angket respons untuk mendapatkan data keefektifan. Analisis data dilakukan melalui analisis deskriptif kuantitatif. Hasil penelitian validitas sebesar 3,77 dikategorikan sangat valid. Hasil kepraktisan sebesar 95% dikategorikan sangat praktis. Hasil keefektifan berdasarkan ketuntasan hasil pretest-posttest sebesar 100%, ketercapaian indikator kemampuan pemecahan masalah sebesar 90%, dan respons positif peserta didik sebesar 99% terkategori sangat efektif. Berdasarkan hasil yang didapatkan, e-LKPD yang dihasilkan berdasarkan aspek kevalidan, kepraktisan, dan keefektifan dinyatakan layak.

The independent learning curriculum is the latest curriculum implemented to realize learning that is student centered and leads to problem solving which is a skill demand in the 21st century. Problem Based Learning is a suitable learning model to be applied in the independent learning curriculum on environmental change material. The PBL model implemented in the form of e-LKPD can stimulate students' activeness in learning and become accustomed to solving existing problems. This study aims to produce a feasible PBL-based e-LKPD on environmental change material to improve the problem solving ability of class X high school students based on the aspects of validity, practicality, and effectiveness. This research is a type of development research with reference to the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Data collection methods were carried out by validation by validators consisting of material expert lecturers, media experts, and high school biology teachers to obtain validity data, observation by observers to obtain practicality data, giving tests and giving response questionnaires to obtain effectiveness data. Data analysis was done through quantitative descriptive analysis. The validity research results of 3.77 were categorized as very valid. The practicality result of 95% is categorized as very practical. The effectiveness results based on the completeness of the pretest-posttest results were 100%, the achievement of problem solving ability indicators was 90%, and the positive response of students was 99% categorized as very effective. Based on the results obtained, the e-LKPD produced based on the aspects of validity, practicality, and effectiveness is declared feasible.
