Penerapan Proyek Steam Eco–Bottle dalam Pembelajaran IPAS Materi Pelestarian Lingkungan untuk Meningkatkan Environmental Awareness pada Siswa Sekolah Dasar

Abstract

This study aimed to examine the implementation of the STEAM Eco-Bottle project, the This study was motivated by the need to strengthen elementary students’ environmental awareness through learning activities that are concrete, contextual, and connected to real environmental issues. Conventional learning activities may provide limited opportunities for students to directly engage in solving environmental problems, highlighting the need for project-based learning that encourages active participation and environmental responsibility. This study aimed to examine the implementation of the STEAM Eco-Bottle project, the improvement of environmental awareness, and differences in improvement among fifth-grade students at SDN Hegarmukti 02. A quantitative approach with a quasi-experimental method and Matching-Only Pretest-Posttest Control Group Design was employed. The sample consisted of 80 students divided into experimental and control groups. Data were collected through pretests and posttests and analyzed using N-Gain, Mann-Whitney U, and Wilcoxon Signed Ranks Tests. The experimental group obtained a posttest mean of 49.05, compared with 46.58 in the control group. The experimental N-Gain was 0.707 (high), while the control group obtained 0.621 (medium). The Wilcoxon test indicated significant pretest-posttest improvement in both groups, while the Mann-Whitney test yielded an Asymp. Sig. of 0.050, with mean ranks of 45.58 for the experimental group and 35.43 for the control group. These findings indicate that the STEAM Eco-Bottle project supports environmental awareness through concrete and contextual learning experiences.
