Abstract
Indonesia: Penelitian ini bertujuan menganalisis penerapan lembar kerja (LK) berbasis proyek dengan memanfaatkan limbah kulit buah naga merah (Hyolocereus polyrhizus) untuk mengembangkan keterampilan proses sains (KPS) peserta didik. Metode yang digunakan adalah pre-eksperimental dengan desain one-shot case study, dilaksanakan di salah satu SMK di Kota Cimahi dengan 31 peserta didik kelas XI Kimia Industri-C. Instrumen penelitian meliputi lembar observasi aktivitas peserta didik, LK berbasis proyek, dan lembar kinerja KPS. Hasil menunjukkan rata-rata aktivitas peserta didik sebesar 95%, nilai kognitif KPS 90%, dan psikomotorik KPS 96%, yang termasuk kategori sangat baik. LK berbasis proyek dalam pembuatan edible straw dari limbah buah naga merah terbukti sangat layak dan efektif untuk mengembangkan KPS peserta didik. English: This study aims to analyze the implementation of project-based worksheets utilizing red dragon fruit peel waste (Hyolocereus polyrhizus) to develop students' science process skills (SPS). The method used was pre-experimental with a one-shot case study design, conducted at a vocational high school in Cimahi City involving 31 students from class XI Industrial Chemistry-C. The research instruments included student activity observation sheets, project-based worksheets, and SPS performance sheets. The results showed an average student activity score of 95%, cognitive SPS score of 90%, and psychomotor SPS score of 96%, all categorized as very good. The project-based worksheet on making edible straws from red dragon fruit peel waste proved to be highly feasible and effective in developing students' SPS.
