Pembelajaran kimia di tingkat sma sering kali dianggap sulit oleh peserta didik, khususnya pada materi struktur atom dan keunggulan nanomaterial yang bersifat abstrak dan kompleks. pendekatan konvensional yang minim interaksi serta kurangnya media pembelajaran interaktif menyebabkan peserta didik kurang memahami konsep secara mendalam. penelitian ini bertujuan untuk mengembangkan dan menguji kelayakan media pembelajaran berupa kalender meja pada materi struktur atom-keunggulan nanomaterial yang diintegrasikan dengan website melalui qr code, serta mengetahui tanggapan guru dan peserta didik terhadap media tersebut. penelitian ini menggunakan pendekatan kualitatif dengan metode research and development (r&d) model 4d (define, design, develop, dan disseminate), dan dilaksanakan di sma katolik banda aceh pada bulan agustus hingga november 2024. subjek penelitian terdiri dari dua dosen ahli media dari universitas syiah kuala, satu guru kimia, dan 20 peserta didik kelas x. media kalender meja yang dikembangkan memuat ringkasan materi, studi kasus, serta qr code yang terhubung ke website berisi video pembelajaran, modul, e-periodic table, lkpd, dan audio penjelasan konsep. hasil validasi menunjukkan bahwa media ini tergolong “sangat layak” digunakan dalam pembelajaran. tanggapan guru dan peserta didik menunjukkan respons yang sangat baik, dan media ini dinilai memiliki tingkat kepuasan pengguna (usability) yang tinggi. dengan demikian, media kalender meja berbasis qr code ini dapat menjadi solusi inovatif dalam pembelajaran kimia, membantu peserta didik memahami konsep abstrak secara lebih interaktif, serta mendukung semangat kurikulum merdeka yang menekankan pada pembelajaran kontekstual berbasis teknologi.

Chemistry learning at the high school level is often perceived as difficult by students, particularly in the topics of atomic structure and the advantages of nanomaterials, which are abstract and complex in nature. The conventional approach, which lacks interaction and engaging instructional media, contributes to students' limited understanding of the concepts. This study aims to develop and evaluate the feasibility of an instructional medium in the form of a desk calendar covering the topic of atomic structure and the advantages of nanomaterials, integrated with a website via QR codes. It also seeks to assess teachers’ and students’ responses to the media. This research employs a qualitative approach using the Research and Development (R&D) method with the 4D model (Define, Design, Develop, and Disseminate), conducted at SMA Katolik Banda Aceh from August to November 2024. The research subjects consist of two media experts from Universitas Syiah Kuala, one chemistry teacher, and 20 tenth-grade students. The developed desk calendar includes a summary of the materials, case studies, and QR codes linking to a website containing instructional videos, modules, an e-periodic table, student worksheets (LKPD), and audio concept explanations. The validation results indicate that the media is considered "highly feasible" for instructional use. Feedback from both teachers and students showed a very positive response, and the media demonstrated a high level of user satisfaction (usability). Therefore, the Desk Calendar Learning Media on Atomic Structure-Nanomaterial Excellence Material integrated with website through QR code can serve as an innovative solution in chemistry learning, helping students better understand abstract concepts in a more interactive way and supporting the spirit of the Merdeka Curriculum, which emphasizes contextual, technology-based learning.
