<![CDATA[ABSTRAK Pemahaman Siswa terhadap materi Informatika masih menjadi permasalahan yang sering dijumpai pada proses pembelajaran di sekolah. Berdasarkan hasil observasi di SMPN 1 Darma, proses pembelajaran masih didominasi metode ceramah dengan penggunaan media pembelajaran yang kurang interaktif sehingga siswa cenderung pasif, mudah bosan, dan mengalami kesulitan dalam memahami materi sistem bilangan. Penelitian ini bertujuan untuk mengembangkan media pembelajaran berbasis Adobe Flash CS6, mengetahui tingkat kelayakan media berdasarkan penilaian ahli dan pengguna, serta mengetahui peningkatan pemahaman siswa setelah menggunakan media pembelajaran yang dikembangkan. Penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan Four D (4D) yang meliputi tahap Define, Design, Develop, dan Disseminate. Pengumpulan data dilakukan melalui tahap observasi, wawancara, angket validasi ahli materi dan ahli media, angket respon pengguna, serta tes pretest dan posttest. Data dianalisis menggunakan analisis deskriptif kuantitatif, uji validitas, realibilitas, tingkat kesukaran, daya pembeda, dan uji N-Gain. Hasil penelitian menunjukkan bahwa media pembelajaran yang dikembangkan memenuhi kriteria “Sangat Layak” berdasarkan penilaian ahli yang memperoleh persentase sebesar 84% dari ahli media dan 84% dari ahli materi. Sedangkan uji coba pengguna memperoleh persentase sebesar 88% pada kelompok kecil dan 89% pada kelompok besar dengan kategori “Sangat Layak”. Selain itu, hasil analisis N-Gain menunjukkan adanya peningkatan pemahaman siswa setelah menggunakan media pembelajaran berbasis Adobe Flash CS6. Dengan demikian, media pembelajaran yang dikembangkan layak digunakan sebagai alternatif media pembelajaran pada mata pelajaran informatika kelas VIII SMP. ABSTRACT Student’s understanding of informatics learning materials remains a common challenge in classroom instruction. Based on observations conducted at SMPN 1 Darma, the learning process was still dominated by lecture based teaching with limited use of interactive learning media, causing students to become passive, easily bored, and experience difficulties in understanding number system concept. This study aims to develop an Adobe Flash CS6 based learning media, determine its feasibilitiy based on expert and user assesments, and identify the improvment in student understanding after using the developed learning media. This study employed a Research and Development (R&D) method using the Four D (4D) development model, consisting of the Define, Design, Develop, and Disseminate stages. Data were collected through obsevation, interviews, material expert and media expert validation questionnaires, user response questionnaires, and pretest posttest. The data were analyzed using quantitative descriptive analysis, validity, reliability, item difficulty, discrimination index, and N-Gain test. The result showed that the developed learning media met the “Very Feasible” criteria, with a feasibility percentage of 84% form the media expert and 84% form the material expert. Meanwhile user trials obtained percentages of 88% in the small group trial and 89% in the large group trial, both categorized as “Very Feasible”. Futhermore, the N-Gain analysis indicated an improvment in student understanding after using the Adobe Flash CS6 based learning media. Therefore, the developed learning media is feasible to be used as an alternative learning medium for Informatics subjects for eight grade junior high school student.]]>
