    Abstract

    Asesmen yang digunakan dalam pembelajaran kimia selama ini umumnya masih berfokus pada hasil akhir dan belum sepenuhnya mampu menilai proses berpikir kreatif serta penguasaan konsep siswa, sehingga diperlukan pengem bangan asesmen yang lebih autentik dan bermakna. Penelitian ini bertujuan untuk menghasilkan instrumen asesmen portofolio elektronik sebagai assess ment for learning yang valid dan reliabel untuk menilai penguasaan konsep dan berpikir kreatif siswa pada materi asam basa. Penelitian ini menggunakan desain Research and Development (R&D) dengan model pengembangan 4D (Define, Design, Develop, dan Disseminate). Partisipan pada penelitian ini berjumlah 30 orang siswa kelas XI di salah satu SMA Negeri di Kota Cimahi. Task yang dikembangkan dalam asesmen portofolio elektronik ini terdiri dari vlog praktikum asam basa dari bahan alam, video pembelajaran penyelesaian soal pH, infografis fenomena dan manfaat asam atau basa dalam kehidupan sehari-hari, foto slide penjernihan air sederhana. Hasil penelitian menunjukkan bahwa instrumen dinyatakan valid dengan nilai CVR 1,00 dan CVI 1,00 dan reliabel dengan nilai 0,8-1,0. Sementara itu, hasil uji coba terbatas dan uji implementasi terhadap instrumen asesmen portofolio elektronik yang dikembangkan menunjukkan instrumen dapat menilai penguasaan konsep dan berpikir kreatif siswa pada materi asam basa yang ditunjukkan dengan hasil uji signifikansi wilcoxon signed rank dengan hasil <0,001 dengan kategori N Gain rendah, sedang, tinggi. Kata kunci: asam basa, asesmen portofolio elektronik, berpikir kreatif siswa, penguasaan konsep, STEM. The assessments used in chemistry learning have generally focused on final outcomes and have not fully captured students’ creative thinking processes and conceptual understanding. Therefore, it is necessary to develop a more authen tic and meaningful assessment. This study aims to develop an electronic port folio assessment instrument as an assessment for learning that is valid and re liable for measuring students’ conceptual understanding and creative thinking on the topic of acids and bases. The study employed a Research and Develop ment (R&D) design with a 4D development model (Define, Design, Develop, and Disseminate). The participants were 30 eleventh-grade students from a public senior high school in Cimahi City. The tasks developed in the electronic portfolio assessment included a vlog of an acid–base experiment using natural materials, a learning video on solving pH problems, an infographic of acid or base phenomena and their applications in daily life, and photo slides of a sim ple water purification project. The results indicated that the instrument was valid with CVR and CVI values of 1.00, and reliable with coefficients ranging from 0.8 to 1.0. Furthermore, the results of limited trials and implementation showed that the developed electronic portfolio assessment could effectively measure students’ conceptual understanding and creative thinking on the acid base topic, as evidenced by the Wilcoxon Signed Rank test results (<0.001) and N-Gain categories of low, medium, and high. Keywords: acids and bases, conceptual understanding, electronic portfolio assessment, STEM, students’ creative thinking
