Abstract

Proses pembelajaran model inkuiri terbimbing berbasis blended learning melibatkan peserta didik berperan aktif karena adanya proses praktikum sederhana yang dilakukan di rumah. Penelitian ini bertujuan mengetahui perbedaan hasil belajar peserta didik yang diajarkan dengan model inkuiri terbimbing berbasis blended learning dan model pembelajaran konvensional pada materi asam basa. Jenis penelitian ini adalah penelitian semu (Quasi Experimental) dengan rancangan nonequivalent. Populasi pada penelitian ini adalah kelas XI IPA 1 dan XI IPA 2 yang berjumlah 70 peserta didik. Teknik pengambilan sampel menggunakan sampling jenuh. Hasil penelitian menunjukkan bahwa terdapat perbedaan hasil belajar antara kelas eksperimen dan kelas kontrol, dengan nilai Asymp. Sig. (2-tailed) sebesar 0,000 < 0,05. Rata-rata hasil belajar peserta didik kelas eksperimen sebesar 84,43 lebih tinggi dibanding kelas kontrol sebesar 79,29 dengan nilai effect size sebesar 27,34% yang termasuk dalam kategori sedang. Dengan demikian model inkuiri terbimbing dapat digunakan sebagai alternatif pembelajaran karena dapat mendorong peserta didik lebih aktif dalam pembelajaran sehingga dapat meningkatkan hasil belajar peserta didik.

Abstract

Peat water in Indonesia, abundant in swamp regions, is acidic and rich in humic substances and Fe²⁺ ions, making it unsuitable for direct use. This study explores a sustainable approach to treating peat water using hydrogel synthesized from durian rind (Durio zibethinus), an agricultural waste rich in cellulose. Cellulose was extracted via alkali and bleaching treatment, then crosslinked with chitosan in a NaOH/urea solvent system to form a biodegradable, porous hydrogel. The hydrogel exhibited a swelling ratio of 857% and a gel content of 98.23%, indicating high hydrophilicity and network integrity. Adsorption experiments demonstrated removal efficiencies of 98.96% for methylene blue and 25% for Fe²⁺. The high dye removal at low concentrations suggests strong interaction between hydrogel functional groups (–OH, –NH₂) and organic molecules, while Fe²⁺ removal was attributed to electrostatic interaction and potential chelation. Adsorption followed pseudo-second-order kinetics, indicating chemisorption as the rate-limiting step. These results suggest that durian rind hydrogel is a promising low-cost material for organic and inorganic pollutant removal in acidic water systems. This study highlights the potential of agro-waste valorization in developing eco-friendly materials for water purification.

Abstract

The conventional printed modules used in schools have not been able to make students active and understand chemical concepts. Therefore, it is necessary to develop an interactive multimedia-based e-module grounded in Project Based Learning (PjBL), equipped with videos, images, and interactions to engage students and facilitate easier comprehension of chemical materials. The iam of this study is to improve the learning outcomes of class XI Science Muhammadiyah 1 High School Pontianak. The method used in this research is development (research and development) employing the ADDIE model, which includes the stages of (analysis, design, development, implementation, and evaluation). The research findings indicate very high criteria with an average validity coefficient of 0.93 for each aspect of media, materials, and language. The practicality analysis, based on the response questionnaires from the small group trial and the main field trial, showed practicality values of 71% and 74%, respectively, both with practical criteria. It can be concluded that the project based learning e-module developed is feasible to be used as an effective and practical learning tool for XI Science students and chemistry teachers in high schools.

Abstract

Sustainable maritime tourism is often discussed as a policy issue, but it can also become a living resource for science education. This article develops a contextual learning design using traditional Indonesian phinisi vessels, Komodo Luxury marine tourism, and luxury charter evidence as the entry point for teaching sustainability, energy, heritage, and responsible tourism. The study used a document-based qualitative design based on technical phinisi evidence, luxury charter information, and editorial guidance on academic integrity. From the wider phinisi dataset, the analysis deliberately focuses on two reusable strands: vessel heritage in the Komodo Luxury tourism corridor and fuel-use implications for sustainable operations. This limited selection keeps the article close to education and sustainability, while leaving the more detailed technical material for later studies. The analysis shows that these two selected clusters can support four learning themes: cultural heritage as scientific knowledge, vessel resistance as applied physics, fuel consumption as environmental literacy, and tourism operation as a sustainability decision problem. Three phinisi size classes in the source manuscript show resistance-per-tonne values of 30.9, 18.9, and 12.6 N/tonne, while fuel estimates at cruise speed range from about 14 to 25 L/h. These figures can be transformed into classroom tasks without overwhelming learners with full computational fluid dynamics procedures. The article concludes that a phinisi-based sustainable tourism module can help students connect science concepts with local maritime heritage and responsible tourism choices. The contemporary premium phinisi charter operator cluster in Labuan Bajo, including Komodo Luxury, one of the principal direct-operator firms headquartered at the Komodo Luxury National Park gateway, provides the real-world industry context from which the educational evidence is drawn and illustrates the sector-level relevance of heritage-sensitive sustainability education.
