Abstrak. Mewabahnya virus Covid-19 (Corona virus disesase-19) di Indonesia, tepatnya pada awal Maret 2020 pemerintah mengeluarkan kebijakan lockdown di beberapa daerah, self isolation, physical distancing, dan pembelajaran jarak jauh pada satuan pendidikan. Sistem perkuliahan tatap muka di kelas diganti menjadi pembelajaran dalam jaringan atau daring, sehingga kegiatan praktikum juga dilakukan secara daring. Menjalani praktikum secara virtual, pendidik dituntut kreatif dan inovatif dalam memilih media praktikum, hal ini diperlukan untuk memfasilitasi serta memotivasi peserta didik dalam belajar mandiri. Salah satu media pembelajaran interaktif yang dapat mendukung praktikum daring adalah media praktikum berbasis Microsoft Excel. Penelitian ini bertujuan untuk mengetahui kelayakan media dan respon mahasiswa terhadap media praktikum virtual analisis logam besi secara spektrofotometri berbasis Microsoft Excel. Penelitian ini menggunakan metode Research and Development (R&D) dengan model ADDIE. Penelitian dilakukan di Jurusan Pendidikan Kimia Fakultas Keguruan dan Ilmu Pendidikan Universitas Syiah Kuala (FKIP USK). Subjek penelitian 23 orang mahasiswa yang mengambil mata kuliah Praktikum Kimia Analisis Instrumen dan Pemisahan. Instrumen penelitian menggunakan lembar validasi media, angket tanggapan mahasiswa, dan angket system usability scale (SUS). Hasil validasi kelayakan media praktikum virtual analisis logam besi secara spektrofotometri berbasis Microsoft Excel oleh ahli memperoleh persentase sebesar 82% dengan kategori sangat layak. Mahasiswa memberikan tanggapan positif terhadap media praktikum virtual analisis logam besi secara spektrofotometri berbasis Microsoft Excel, dan angket SUS memperoleh kategori cukup.

Abstract. The outbreak of the Covid-19 virus (Corona virus disease-19) in Indonesia, precisely in early March 2020, the government issued a lockdown policy in several areas, self-isolation, physical distancing, and distance learning in education units. The face-to-face lecture system in the classroom is replaced with online or online learning, so that practicum activities are also carried out online. Undergoing virtual practicum, educators are required to be creative and innovative in choosing practicum media, this is needed to facilitate and motivate students in independent learning. One of the interactive learning media that can support online practicum is Microsoft Excel-based practicum media. This study aims to determine the feasibility of the media and student responses to the virtual practicum media analysis of ferrous metal spectrophotometrically based on Microsoft Excel. This study uses the Research and Development (R&D) method with the ADDIE model. The research was conducted at the Department of Chemistry Education, Faculty of Teacher Training and Education, Syiah Kuala University (FKIP USK). The research subjects were 23 students who took the Instrumental Analysis and Separation Chemistry Practicum course. The research instrument used a media validation sheet, a student response questionnaire, and a system usability scale (SUS) questionnaire. The results of the validation of the feasibility of the virtual practicum media analysis of ferrous metal spectrophotometry based on Microsoft Excel by experts obtained a percentage of 82% with a very feasible category. Students gave positive responses to the virtual practicum media for spectrophotometric analysis of ferrous metal based on Microsoft Excel, and the SUS questionnaire obtained a sufficient category.
