Abstract

The Human Excretory System is an abstract, microscopic topic that often causes student misconceptions. This R&D study, using the ADDIE model, developed an Audio-Comic Video integrated with Marker-Based Augmented Reality (AR), using Assemblr 3D assets to interactively visualize excretory organs. The subjects were eleventh-grade students at SMAS Muhammadiyah Jayapura. Validation results showed the medium was very valid according to the material expert (92.22%) and valid according to the media expert (81.25%). Practicality tests with students (93.57%) and teachers (88.57%) fell into the very practical category. The effectiveness test on 35 students showed scores increasing from 50.02 (pretest) to 84.07 (posttest), with an N-Gain of 0.626 (medium category) and a significant difference (Sig. 2-tailed = 0.000). The medium proved feasible and effective as an alternative biology learning medium accommodating visual, auditory, and kinesthetic learning styles.

Abstract

  Penelitian ini mengembangkan serta menguji validitas isi dan keterbacaan instrumen Scientific Literacy Assessment (SLA) terintegrasi etnokimia berbasis sistem Artificial Intelligence (AI) pada materi stoikiometri kelas XI. Penelitian menggunakan metode Research and Development yang diadaptasi dari model ADDIE, dibatasi sampai tahap Development (Analysis, Design, Development), dan dilaksanakan di SMA YPPK Taruna Dharma, Jayapura. Analisis kebutuhan yang melibatkan guru kimia menunjukkan bahwa asesmen selama ini masih berorientasi pada penguasaan konsep dan perhitungan rutin, belum mengukur literasi sains, dan belum mengintegrasikan budaya lokal. Sebanyak 15 butir soal uraian dikembangkan dengan menyisipkan konteks etnokimia Papua, seperti pengolahan sagu, pembakaran kayu tradisional, pengasapan ikan, dan pemanfaatan kapur sirih, yang masing-masing dilengkapi rubrik penskoran dan struktur umpan balik berbasis AI. Validitas isi yang dinilai oleh 10 validator (tujuh dosen pendidikan kimia dan tiga guru kimia) menggunakan indeks Aiken's V menunjukkan seluruh butir valid, dengan nilai berkisar 0,85 hingga 0,97 (rerata 0,91). Uji coba terbatas terhadap 15 siswa kelas XI menunjukkan keterbacaan yang baik serta respons positif terhadap penskoran dan umpan balik langsung dari sistem AI, meskipun sebagian siswa masih kesulitan mengubah informasi naratif menjadi langkah kuantitatif. Instrumen ini berpotensi menjadi alternatif asesmen yang valid dan kontekstual, namun memerlukan pengujian empiris skala luas
