IMPLEMENTASI MODEL PROBLEM BASED LEARNING (PBL) BERBANTUAN E-BOOK UNTUK MENINGKATKAN KETERAMPILAN PEMECAHAN MASALAH SISWA SMA PADA MATERI ENERGI TERBARUKAN

IMPLEMENTATION OF PROBLEM BASED LEARNING (PBL) MODEL ASSISTED BY E-BOOK TO IMPROVE PROBLEM SOLVING SKILLS OF HIGH SCHOOL STUDENTS ON RENEWABLE ENERGY MATERIAL

Penelitian ini bertujuan untuk mendeskripsikan keterlaksanaan pembelajaran, peningkatan keterampilan pemecahan masalah, dan respon peserta didik terhadap pembelajaran menggunakan model Problem Based Learning (PBL) berbantuan E-Book pada materi energi terbarukan. Penelitian ini menggunakan jenis pre-eksperimen dengan desain one group pretest posttest. Subjek penelitian terdiri atas 3 kelas, yaitu kelas eksperimen, kelas replikasi 1, dan kelas replikasi 2 yang semua kelas diterapkan model PBL berbantuan E-Book. Teknik pengumpulan data melalui metode observasi, tes, dan angket. Data dari penelitian ini kemudian dianalisis dengan lembar observasi keterlaksanaan, uji prasyarat berupa uji normalitas dan homogenitas, uji-t berpasangan untuk mengetahui keterampilan pemecahan masalah, analisis n-gain, ANAVA, dan analisis angket respon peserta didik. Hasil penelitian menunjukkan bahwa: 1) Keterlaksanaan pembelajaran dengan model PBL berbantuan E-Book terlaksana dengan sangat baik. 2) Terjadi peningkatan keterampilan pemecahan masalah peserta didik setelah menerapkan pembelajaran dengan model PBL berbantuan E-Book.  Peningkatan keterampilan pemecahan masalah pada ketiga kelas tersebut signifikan dengan nilai n-gain yang tinggi, serta peningkatan keterampilan pemecahan masalah konsisten di ketiga kelas. 3) Peserta didik memberikan respon yang sangat baik dan positif terhadap pembelajaran dengan model PBL berbantuan E-Book, sehingga peserta didik menyetujui terhadap penggunaan model ini dalam proses pembelajaran. Berdasarkan hasil penelitian, dapat disimpulkan bahwa implementasi model PBL berbantuan E-Book dapat meningkatkan keterampilan pemecahan masalah peserta didik pada materi energi terbarukan.

This study aims to describe the implementation of learning, improvement of problem-solving skills, and students' responses to learning using the Problem-Based Learning (PBL) model assisted by E-Book on renewable energy material. This study used a type of pre-experiment with a one-group pretest posttest design. The research subjects consisted of 3 classes, namely the experimental class, replication class 1, and replication class 2, all of which applied the PBL model assisted by E-Book. Data collection techniques through observation, test, and questionnaire methods. The data from this study were then analyzed with the implementation observation sheet, preliminary tests in the form of normality and homogeneity tests, paired t-tests to determine problem-solving skills, n-gain analysis, ANOVA, and analysis of student response questionnaires.  The results showed that: 1) The implementation of learning with the PBL model assisted by E-Book was very well implemented. 2) There was an increase in students' problem-solving skills after implementing learning with the PBL model assisted by E-Book.  The increase in problem-solving skills in the three classes was significant with a high n-gain value, and the improvement in problem-solving skills was consistent in the three classes. 3) Students gave very good and positive responses to learning with the PBL model assisted by E-Book, so that students agreed to the use of this model in the learning process. Based on the results of the study, it can be concluded that the implementation of the PBL model assisted by E-Book can improve students' problem-solving skills on renewable energy material.
