Penelitian ini bertujuan mendeskripsikan validitas dan kepraktisan E-book sehingga didapatkan E-book yang layak untuk melatihkan keterampilan literasi digital pada materi perubahan lingkungan ssiwa SMA. Penelitian mengacu pada  model pengembangan 4D yaitu define, design, develop, dan desseminate. Penarikan sampel uji coba terbatas dilakukan oleh 27 orang siswa kelas X IPA 5 SMA 17 Agustus 1945 Surabaya. Data hasil validasi E-book diperoleh dari tiga validator sedangkan kepraktisan E-book diperoleh dari uji angket respon siswa yang kemudian dianalisis secara deskriptif kuantitatif. Hasil akhir uji validasi E-book  mendapat persentase skor 91,35 % tergolong kategori sangat valid. Hasil angket respons siswa memperoleh  skor 97,60 % tergolong kategori sangat praktis. Keefektifan E-book ditinjau dari analisis n-gain hasil pretest dan posttest dinyatakan efektif dengan skor n-gain sebesar 0.72 dengan kategori tinggi. Oleh sebab itu, pengembangan E-book  dinyatakan layak menurut aspek validitas dan kepraktisan dan cocok digunakan untuk media belajar. 

Digital literacy skills are an interesting topic of discussion because they help students to design strategies for solving problems and storing information. It is hoped that the existence of E-book media based on creative problem solving can train students' digital literacy skills on environmental change material. This research aims to describe the validity and practicality of E-books so that an E-book is suitable for practicing digital literacy skills on environmental change material for high school students. The research refers to the 4D development model, namely define, design, develop and desseminate. Limited trial sampling was carried out by 27 students of class X MIPA SMA 17 August 1945 Surabaya. Data from the E-book validation results were obtained from three validators, while the practicality of the E-book was obtained from student response questionnaire tests which were then analyzed quantitatively descriptively. The final results of the E-book validation test received a score percentage of 91.35% in the very valid category. The results of the student response questionnaire obtained a score of 97.60% in the very practical category. The effectiveness of the E-book in terms of the n-gain analysis of the pretest and posttest results was declared effective with an n-gain score of 0.72 in the high category. Therefore, the development of E-books is declared feasible according to aspects of validity and practicality and suitable for use as learning media.
