ABSTRAK

Tujuan penelitian adalah menghasilkan e-Book Fisika menggunakan flip PDF professional untuk melatihkan keterampilan berpikir kritis siswa SMA yang layak (valid, praktis dan efektif). Jenis penelitian ini adalah penelitian pengembangan dengan model ADDIE (Analysis, Design, Development, Implementation, Evaluation) dan subjek penelitian adalah 24 siswa kelas XI SMA Muhammadiyah 9 Surabaya. Teknik pengumpulan data adalah angket, pengamatan dan tes.  Validitas ditinjau dari validitas e-Book fisika pada aspek pembelajaran, materi, dan media; kepraktisan ditinjau dari keterlaksanaan dan kendala pembelajaran; serta keefektifan ditinjau dari keterampilan berpikir kritis dan respon siswa. Teknik analisis data validitas dan kepraktisan e-Book fisika diukur menggunakan skala Likert, sedangkan keefektifan e-Book fisika berdasarkan hasil tes diukur menggunakan skala Likert dan hasil respon siswa diukur menggunakan skala Guttman. Kemudian, skor yang diperoleh ditentukan presentase validitas, kepraktisan dan keefektifannya. E-Book fisika dinyatakan layak apabila mendapat nilai ≥ 61%. Hasil penelitian menunjukkan bahwa validitas e-Book fisika berada pada ketegori sangat baik (aspek pembelajaran 89,58%, aspek materi 93,27%, aspek media 92,50%); kepraktisan e-Book fisika berdasarkan keterlaksanaan pembelajaran berada pada kategori sangat baik dengan persentase 91,07%; serta keefektifan e-Book fisika berdasarkan keterampilan berpikir kritis berada pada kategori sangat baik dan baik (interpretasi 82,29%, menjelaskan 79,17%, analisis 71,88%, menyimpulkan 78,13%, evaluasi 68,75%) dan respon siswa berada pada kategori sangat baik dengan persentase 92,65%. Kesimpulan penelitian adalah e-Book fisika menggunakan flip PDF professional layak untuk melatihkan keterampilan berpikir kritis siswa SMA.

ABSTRACT

The purpose of research is to develope physics e-Book using flip PDF professional to train critical thinking skills which feasible (valid, practical and effective). Type of research is development using ADDIE model (Analysis, Design, Development, Implementation, Evaluation) and subject of research are 24 students of Muhammadiyah 9 Senior High School (XI grade science). Data collection techniques are questionnaire, observation and test. Validity are based on validity of physics e-Book on aspect of learning, material, and media; practically are based on the implementation and obstacle of learning; and effectiveness are based on student’s critical thinking skills and  response. Data analysis techniques validity and practicality of physics e-Book using  Likert scale, while the effectiveness of physics e-Book based on the results of the test using a Likert scale and the results of student responses using the Guttman scale. Then, the score obtained is determined by the percentage of validity, practicality and validity. Physics e-Book stated feasible if its get score ≥ 61%. The result showed that the validity was in excellent category (learning aspect 89,58%; material aspect 93,27%; media aspect 92,50%); practically of physics e-Book which based on implementation of learning was in excellent category with percentage 91,07%; and effectiveness of physics e-Book are based on critical thinking skills was in good and excellent category (interpretation 82,29%, explanation 79,17%, analysis 71,88%, inference 78,13% evaluation 68,75%) and student’s response was in excellent category with percentage 92,65%. The conclusion of research is physics e-Book using flip PDF professional feasible to train Senior High School student’s critical thinking skills.
