Penelitian ini bertujuan mengembangkan media pembelajaran digital berdasarkan Seleksi Nasional Berbasis Teks. Melalui jenis penelitian pengembangan model 4D (penetapan, perancangan, pengembangan, diseminasi), dikembangkan Situs Informasi Bahasa Indonesia untuk Semua (SIBIUS) dalam bentuk website yang mengintegrasikan beberapa platform interaktif lain. Pada tahap perancangan, dibahas pengumpulan materi, rancangan alur website, dan platform yang diintegrasikan. Pada tahapan pengembangan, dibahas penyajian dan substansi SIBIUS yang terdiri dari halaman beranda, materi, latihan soal, forum, kontak, grup, dan berbagi berkas. Materi yang diangkat adalah kaidah kebahasaan (sintaksis-semantik) dan literasi yang disajikan dalam bentuk visual (Canva), audio (VoiceThread), serta isyarat (HandTalk). Adapun latihan soal disajikan dalam platform interaktif seperti Oodlu, WordWall, Wizer.me, dan dibahas secara audio-visual. Ragam kebahasaan SIBIUS adalah formal-interaktif. Media pembelajaran divalidasi oleh ahli media pembelajaran dan bahasa. Hasil diseminasi mendapat respons dan komentar yang positif sehingga membuktikan kelayakan SIBIUS untuk diimplementasikan. 

Development of the Indonesian Language Information System for All (SIBIUS) Based on the Needs of Test-Based National Selection

This study aims to develop digital learning media based on the National Text-Based Selection. Through the type of 4D model development research (determination, design, development, dissemination), the Indonesian Language Information Site for All (SIBIUS) was developed as a website that integrates several other interactive platforms. At the design stage, the materials collection, the website flow design, and the integrated platforms were discussed. At the development stage, the presentation and substance of SIBIUS were discussed, consisting of the home page, materials, practice questions, forums, contacts, groups, and file sharing. The materials raised are language rules (syntax-semantics) and literacy presented in visual (Canva), audio (VoiceThread), and gesture (HandTalk) forms. The practice questions are presented in interactive platforms such as Oodlu, WordWall, Wizer.me, and discussed audio-visually. The language variety of SIBIUS is formal-interactive. The learning media was validated by experts in learning media and language. The results of the dissemination received positive responses and comments, thus proving the feasibility of SIBIUS for implementation.
