Abstract

Kurangnya ketertarikan siswa untuk mempelajari materi trigonometri melatarbelakangi penelitian ini. Tujuan penelitian ini untuk menghasilkan media pembelajaran berbasis android menggunakan Adobe Flash CS6 yang valid dan praktis serta untuk mengetahui tingkat kemandirian belajar siswa. Penelitian ini merupakan penelitian pengembangan dengan model ADDIE (Analyze, Design, Development, Implementation dan Evaluation). Subjek penelitian adalah siswa kelas X SMAN 3 Kota Solok. Instrumen penelitian berupa angket validasi, angket uji praktikalitas dan angket kemandirian belajar siswa. Berdasarkan hasil penilaian validator yaitu ahli media dan ahli materi diperoleh persentase penilaian akhir kevalidan media pembelajaran 87,5% dengan kategori sangat valid. Nilai akhir uji coba kepraktisan dengan guru dan siswa diperoleh persentase 91,71% dengan kategori sangat praktis, hasil uji kemandirian belajar siswa diperoleh nilai rata-rata 84,78% dengan kategori sangat mandiri. Dapat disimpulkan bahwa media pembelajaran berbasis android menggunakan Adobe Flash CS6 pada materi trigonometri sudah valid dan praktis serta dapat membantu siswa untuk belajar secara mandiri.

Abstract

School websites serve as important media for delivering information and digital services to users. However, a website that does not pay attention to usability aspects can reduce its effectiveness. This study aims to redesign the website of MA Taruna Teknik Al Jabbar Medan based on the User Centered Design (UCD) approach, using usability analysis conducted with the System Usability Scale (SUS) method. The research employs a quantitative approach by distributing a SUS questionnaire consisting of 10 Likert-scale statements to students and teachers as website users. The SUS score results are used to identify usability issues in the existing website. Based on the analysis results, a website redesign is carried out following the UCD stages, including understanding the context of use, specifying user requirements, producing design solutions, and evaluating the design. The results of this study are expected to produce a website design that is more effective, efficient, and easy to use, as well as to improve user satisfaction with the school website.
