Abstract

Limbah plastik merupakan jenis sampah yang sulit terurai dan berkontribusi terhadap degradasi lingkungan, termasuk di lingkungan sekolah yang memiliki aktivitas konsumsi tinggi. Upaya peningkatan literasi lingkungan pada siswa diperlukan untuk mendorong pengelolaan sampah yang lebih bertanggung jawab. Penelitian ini bertujuan meningkatkan kesadaran dan keterampilan siswa dalam mengolah limbah plastik menjadi produk bernilai guna melalui pendekatan edukatif berbasis prinsip 3R (Reduce, Reuse, Recycle). Metode yang digunakan mencakup sosialisasi konsep dasar pengelolaan sampah plastik, demonstrasi teknik daur ulang, serta praktik langsung pembuatan produk kreatif seperti pot tanaman, wadah alat tulis, dan hiasan kelas. Evaluasi dilakukan melalui observasi partisipasi, wawancara, serta penilaian hasil karya siswa. Hasil menunjukkan adanya peningkatan pemahaman siswa terkait pengelolaan limbah plastik dari 75% menjadi 88,9%, disertai kemampuan menghasilkan berbagai produk kreatif berbahan plastik bekas. Dengan demikian, program edukasi berbasis 3R terbukti mampu memperkuat literasi dan keterampilan pengelolaan limbah plastik siswa serta layak direkomendasikan sebagai model pengelolaan sampah berkelanjutan di lingkungan sekolah.

Abstract

STEM-based learning (Science, Technology, Engineering, and Mathematics) has the potential to enhance the relevance of biology education to 21st-century life through interdisciplinary and project-based approaches. However, its implementation in Indonesia still faces various challenges. This review article aims to identify the key barriers to implementing STEM in biology education, particularly concerning teacher readiness, facilities and infrastructure, and educational policy support. This study employed a narrative literature review method based on 15 national and international journal articles published between 2015 and 2025. Sources were collected through Google Scholar, DOAJ, ScienceDirect, and SpringerLink using the keywords “STEM education,” “biology learning,” and “Indonesia.” The review found four major challenges: (1) limited teacher competence in designing interdisciplinary learning; (2) lack of laboratory and technological facilities; (3) misalignment between the curriculum and assessment systems with STEM principles; and (4) low student motivation and literacy in STEM. Several initiatives, such as teacher training, project-based learning practices, and the integration of local contexts, have shown promising results. This study highlights the need for comprehensive strategies to strengthen teacher capacity, provide adequate infrastructure, and align educational policies to ensure that STEM implementation in biology education can be more effective and sustainable in the Indonesian context.

Abstract

This study aims to describe the level of conservation literacy of prospective biology teachers. Data were obtained through a survey using a Likert-scale questionnaire with three main aspects (knowledge, attitudes, and skills). Respondents were seventh-semester students who completed the instrument online. The resulting data were then analyzed descriptively. The results showed that the knowledge aspect was classified as good, although participation in scientific forums was still low. The attitude aspect was categorized as very good, but discipline in energy conservation needs to be improved. The skills aspect was classified as good but needed strengthening through creative activities such as composting, ecobricks, and school conservation projects. The conservation action aspect was not optimal because the activities were still individual and simple, so support and training were needed to encourage collaborative involvement. The conclusion of this study confirms that the conservation literacy of prospective biology teachers is quite developed at the level of knowledge and attitudes, but is still limited in the implementation of concrete actions.
