Abstract

High consumption of coal as a source of electrical energy in Indonesia has resulted in piles of waste from coal burning, namely fly ash, which can damage the environment and harm health. Fly ash contains main oxides, namely silica (SiO2) and alumina (Al2O3), whose components are similar to zeolite, so they can be synthesized into zeolite-like material (ZLM) which can be used as an adsorbent for heavy metal Ni2+. Therefore, this research discussed the characterization of manganese-oxide-coated-zeolite (MOCZ) from fly ash waste as a heavy metal adsorbent. The research procedure consisted of preparation, purification, and activation stage of fly ash to obtain fly ash that is free from impurities, the stage of making sodium silicate and sodium aluminate, and zeolite synthesis. The resulting zeolite was then coated with manganese oxide to expand the surface area of the zeolite and increase the ability of zeolite to adsorb heavy metal Ni2+. The research results showed that fly ash waste that was coated with manganese oxide can adsorb heavy metal Ni2+. The adsorption of the Ni2+ metal ion solution by zeolite with MOCZ modification is in line with the pseudo-second-order kinetic and Langmuir isotherm.

Abstract

This mixed-method research aimed to analyze the influence of the PjBL-STEAM learning model on the creative thinking skills of grade XI students through a jumputan batik pattern-making project. The main problem was the demand for creative adaptation skills in the 21st century. By collecting data through product assessment observations, questionnaires, and interviews, this study found that the PjBL-STEAM model had a positive and strong impact, particularly in the aspects of fluency and flexibility, which reached 75.50%–78.00%. However, significant challenges were found in the aspects of originality and elaboration, with lower scores (52.27%–58.20%), indicating the need for further development on the innovation and detail of students' work. Overall, the PjBL-STEAM model is effective, but it requires more specific guidance to encourage the generation of unique and detailed ideas.

Abstract

Science learning in schools tends to be theoretical and less related to real contexts, so students have difficulty understanding the application of concepts in everyday life. One of the causes is the lack of teaching materials that integrate local wisdom. This study aims to examine the concepts of science in the local wisdom of making Batik Besurek to be developed as ethnoscience content in integrated science e-books and to determine the level of validity and student response to the product. The method used is research and development (R&D), according to Borg and Gall (1983), using the Model of Educational Reconstruction (MER) approach. Data were obtained through questionnaires, observations, and interviews. The results of the study showed that the process of making Batik Besurek contains the concepts of temperature and heat, expansion, changes in the state of matter, physical changes, heat transfer, and Black's principle, which can be integrated into the content of the Integrated Science Electronic Book. The developed electronic book obtained a very high level of validity with an average V index of 0.86 and a percent agreement of 89.27%. The students' response to the book was also excellent, with an average percentage of 89.42%. The results concluded that the Integrated Science electronic book containing the ethnoscience of Batik Besurek Bengkulu was considered valid teaching material worthy of being tested for effectiveness in future research.

Abstract

Usaha cemilan sehat berbasis UMKM merupakan usaha yang cukup menjanjikan karena tumbuhnya kesadaran di masyarakat terhadap makanan sehat. Salah satu UMKM yang berpotensi untuk mengembangkan cemilan sehat adalah usaha kue rumahan Roti Rizka yang dikelola oleh Ibu Rizka Lailiyah. Permasalahan pada usaha kue rumahan ini adalah belum ada inovasi produk yang daya saingnya lebih kompetitif, peralatan masak masih sederhana, dan pemasaran masih konvensional. Tujuan Progam Kemitraan Masyarakat (PKM) ini adalah mengembangkan varian produk cemilan sehat gluten free sebagai produk unggulan yang kompetitif,, meningkatkan efisiensi dan kapasitas, memperluas jangkauan pasar melalui pendampingan pemasaran digital, serta memastikan legalitas produk. Metode yang dilakukan yaitu sosialisasi, pelatihan, dan pendampingan kepada mitra dalam pembuatan dan pengemasan produk brownies kukus, brownies panggang, dan cookies chocochips gluten free. Produk cemilan yang dihasilkan diperiksa kualitasnya melalui uji organoleptik. Selanjutnya, dilakukan pendampingan pegajuan sertifikat PIRT dan perluasan jangkauan pemasaran melalui outlet dan e-commerce. Hasil dan dampak dari kegiatan ini adalah mitra yang terampil membuat inovasi produk berupa cemilan sehat gluten-free yang layak dipasarkan berdasarkan uji organoleptik. Selain itu penguatan kapasitas UMKM juga dicapai melalui pemberian bantuan oven dan etalase kaca, serta legalitas produk cookies dengan terbitnya nomor P-IRT 6053313011080-30. Kesiapan pemasaran UMKM ini juga meningkat dari metode konvensional menjadi lebih modern.

Abstract

Background: Environmental issues are integral to science education, addressing the causes, impacts, and prevention of environmental damage. Investigative learning is essential to help students better understand these complex topics.Aim: This study aimed to determine the characteristics and feasibility of the Climate Change Investigation (CCI) module in empowering students’ sustainability literacy and global diversity.Method: The research employed a Research and Development (R&D) approach using the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. Data collection included expert validation and student-teacher response questionnaires.Results: The findings showed that the CCI module is an effective and engaging tool for enhancing students’ understanding of environmental issues and cultural awareness. The module also benefits teachers by introducing interactive, low-carbon, and sustainability-based learning media. Validation scores from material, media, and language experts confirmed its high feasibility. Student and teacher responses indicated a high level of satisfaction with the module's clarity, content, and relevance.Conclusion. The CCI module enables students to understand various causes and impacts of environmental degradation, recognize the regional variations in climate effects, appreciate the role of biodiversity, evaluate the influence of eco-friendly technologies, and participate actively in discussions. The module supports independent learning and contributes to shaping environmentally and culturally conscious students aligned with 21st-century educational goals.

Abstract

Background: Environmental damage in Indonesia is worsening, as shown by the low Environmental Performance Index and limited public awareness, which reflect low student environmental literacy. The Culturally Responsive Transformative Teaching (CRTT) model provides a contextual approach by integrating cultural values to enhance knowledge, attitudes, and pro-environmental behaviors.Aims and scope of paper: This study aims to determine the effect of the Culturally Responsive Transformative Teaching (CRTT) model on science learning on the environmental literacy of 7th grade students.Methods: This study used a quasi-experimental method with a pretest-posttest control group design. The sampling technique was selected using cluster random sampling. The research instrument was the MSELS instrument adapted from Mc.Beth and Volk (2009) in the form of multiple-choice tests and questionnaires tailored to the 7th grade science material on ecology and biodiversity. The research sample used class 7 H as the control class with a discovery learning model consisting of 32 students and class 7I as the experimental class with a CRTT model consisting of 31 students.Result: The results showed that the CRTT model in science learning had an effect on the environmental literacy of 7th grade students with a significance value of 0.000 (0.000< 0.05).Conclusion: The study concludes that the CRTT model effectively enhances students’ environmental literacy in science learning, highlighting the need for cultural integration and further research across diverse contexts.
