Abstract

This study evaluates the effectiveness of a participatory greening program in implementing a Green Campus and achieving SDG 12 among Biology students. A quantitative pre-experimental, one-group pre-test post-test design was employed with 36 undergraduate student selected by purposive sampling. Instruments included expert-validated knowledge tests, environmental questionnaires, and observation checklist (content validity index of 1.00). The four-week program involved activities such as planting, watering, weeding, fertilizing, and monitoring, specially designed to promote sustainable consumption and production practice-including organic fertilization efficient water usage, composting, and responsible resources management. Student participation averaged 78.6%. Statistical analysis using the Wilcoxon signed-rank test indicated a significant increase in environmental knowledge (Z = -5.12, p < 0.001) with a moderate-to-high N-gain score of 0.66. Additionally, students’ environmental care attitude improved significantly, with the mean score rising from 72.4 to 88.7 (Δ = 16.3), categorized as “very positive”. These findings demonstrate that the greening program is empirically effective in improving ecological literacy and foresting pro-environmental attitude while reinforcing sustainable production principles. Therefore, this program can be adopted as a scalable and sustainable model for Green Campus initiative in higher education.

Abstract

Single-use plastic waste remains a major environmental challenge on university campuses due to its intensive use and low degradability, increasing waste management burdens and pollution risks. This study evaluated the effectiveness of the Plastic-Free Campus Movement in promoting sustainable lifestyles among Biology students and reducing single-use plastic waste on campus. A one-group pre-test–posttest pre-experimental design with quantitative descriptive and observational approaches was employed involving 80 Biology and Biology Education students at the Faculty of Mathematics and Natural Sciences, State University of Surabaya. Data were collected through pre-tests, post-tests, attitude and response questionnaires, and waste-volume observation sheets, and analysed using descriptive statistics, the Shapiro–Wilk normality test, the Wilcoxon signed-rank test, and N-gain analysis. The educational media and research instruments were highly valid with a feasibility score of 100%. Students' knowledge increased significantly from 54.55 to 92.76 (p < 0.05) with a high N-gain score (0.84). Student attitudes (84.55%) and programme responses (82.47%) were categorised as very good. In addition, the average plastic waste-bin occupancy decreased from an overflow condition equivalent to 104% of bin capacity in the first week to 24% of bin capacity by the fourth week. These findings demonstrate that the Plastic-Free Campus Movement effectively improved students' environmental awareness and sustainable behaviour while contributing to measurable reductions in campus plastic waste, providing a practical educational strategy to strengthen Green Campus initiatives and support SDG 12.5.

Abstract

Permasalahan sampah botol plastik di kawasan perkotaan seperti Kota Surabaya terus meningkat seiring dengan pertumbuhan konsumsi masyarakat, sementara kapasitas daur ulang masih terbatas dan sebagian besar limbah plastik berakhir di tempat pembuangan akhir. Di sisi lain, ketersediaan bahan baku rotan sebagai material utama kerajinan anyaman semakin terbatas dan mahal, sehingga menghambat keberlanjutan usaha kerajinan masyarakat. Program pengabdian ini bertujuan menerapkan teknologi ekstruder filamen untuk mengolah botol plastik bekas menjadi filamen plastik sebagai bahan alternatif pengganti rotan sekaligus memberdayakan masyarakat Desa Gading Watu, Kabupaten Gresik. Metode pelaksanaan meliputi edukasi ekonomi sirkular, pembuatan alat ekstruder, pelatihan pengolahan botol plastik menjadi filamen, pelatihan anyaman, pendampingan produksi, serta persiapan pemasaran produk. Hasil kegiatan menunjukkan bahwa teknologi ekstruder filamen dapat dioperasikan secara mandiri oleh masyarakat dan mampu menghasilkan filamen plastik yang layak digunakan sebagai bahan anyaman. Masyarakat berhasil memproduksi berbagai produk kerajinan seperti keranjang, pot tanaman, dan kotak serbaguna dengan bahan filamen plastik. Program ini berkontribusi dalam mengurangi limbah plastik, meningkatkan keterampilan dan pendapatan masyarakat, serta mendorong penerapan ekonomi sirkular berbasis komunitas.
