<![CDATA[Abstrak Penelitian ini bertujuan untuk menghasilkan bahan ajar digital learning object of physics (DiLO-Phy) berbasis multi representasi menggunakan aplikasi sway untuk mata pelajaran fisika materi gelombang bunyi SMA kelas XI. DiLO-Phy ini dirancang sebagai bahan ajar yang dioperasikan secara mandiri. Penelitian ini menggunakan metode penelitian dan pengembangan (reasearch and development) dengan metode 4D (define, design, develop, disseminate). Langkah pengembangan pada penelitian ini terdiri dari sepuluh langkah, yaitu menganalisis kurikulum dan kompetensi dasar materi, mengidentifikasi karakteristik peserta didik, memilih tugas-tugas pokok yang harus dikuasai, merumuskan tujuan pembelajaran, memilih media pembelajaran, merancang format isi, membuat kerangka model bahan ajar DiLO-Phy, melaksanakan evaluasi formatif untuk kelayakan bahan ajar DiLO-Phy, merevisi berdasarkan evaluasi kelayakan produk, melakukan uji coba terbatas pada peserta didik. Berdasarkan hasil uji kelayakan, diperoleh rata-rata persentase capaian untuk ahli materi sebesar 96.5% dan ahli media sebesar 81%. Uji coba produk dilakukan kepada guru fisika SMA dengan rata-rata persentase capaian sebesar 94.20% dan peserta didik kelas XI sebesar 82.43%. Rata-rata nilai tersebut menunjukkan bahwa kualitas bahan ajar DiLO-Phy berbasis multi representasi mendapatkan nilai sangat layak dan dapat digunakan sebagai bahan ajar bagi guru dan peserta didik kelas XI.

DiLO-Phy designed as a teaching material that is operated independently. This research used research and development methods (research and development) with the 4D method (define, design, develop, disseminate). The development steps in this study consisted of ten steps, namely analyzing the curriculum and basic competencies of the material, identifying the characteristics of students, choosing the main tasks that must be mastered, formulating learning objectives, selecting learning media, designing content formats, creating a model framework for DiLO-Phy teaching materials, carry out formative evaluations for the feasibility of DiLO-Phy teaching materials, revise based on product feasibility evaluations, conduct limited trials on students. Based on the results of the feasibility test, the average percentage of achievement for material experts is 96.5% and media experts is 81%. Product trials were carried out on high school physics teachers with an average percentage of achievement of 94.20% and class XI students of 82.43%. The average value indicates that the quality of DiLO-Phy teaching materials based on multi-representation gets a very decent score and can be used as teaching material for teachers and students of class XI.
