Abstract

Education is a key pillar of a nation's progress. Results from the Program for International Student Assessment (PISA) 2022 indicate that Indonesian students' performance in reading, mathematics, and science remains below international averages, reflecting persistent challenges in higher-order thinking and problem-solving skills. This study aimed to develop STEM- based teaching materials integrated with 21st-century learning to enhance students' critical thinking skills. The research employed a Research and Development (R&D) approach using the 4D model (define, design, develop, disseminate). Participants included material and media experts, chemistry teachers, and 36 Grade XI students. Critical thinking skills were measured using pretest–posttest assessments aligned with Ennis' indicators, expert validation sheets, and student response questionnaires. The results showed that expert feasibility ratings reached 98.05% (highly feasible), user responses were 88.79%, and readability was 87.83%. The effectiveness of the materials was supported by a high N-Gain score of 0.73, indicating substantial improvement in students' critical thinking skills. Overall, the developed teaching materials were feasible, well-received, and effective in improving students' critical thinking skills. These findings imply that systematically integrating STEM principles with 21st-century learning skills can serve as an effective instructional strategy to strengthen higher-order thinking in chemistry education. Future research is recommended to conduct large-scale experimental studies across diverse school contexts and to explore digital integration to enhance scalability and long-term impact.

Abstract

Integrasi Small-Scale Chemistry (SSC) dalam pembelajaran kimia merupakan pendekatan inovatif untuk mendukung prinsip Green Chemistry dengan cara meminimalkan penggunaan bahan kimia, meningkatkan keselamatan laboratorium, dan mendorong penggunaan indikator alami yang lebih ramah lingkungan. Penelitian ini bertujuan untuk menganalisis bagaimana pelatihan SSC terstruktur memengaruhi persepsi siswa terkait keselamatan, desain ramah lingkungan, kepercayaan diri, dan keberlanjutan. Sebanyak 30 siswa kelas XI SMA Negeri 6 Semarang berpartisipasi dalam kegiatan ini yang dirancang secara kolaboratif oleh Departemen Kimia FMIPA Universitas Negeri Semarang bersama Sogang University dan program LUPIC. Instrumen penelitian berupa kuesioner dengan 8 butir pertanyaan berbasis empat indikator kompetensi. Analisis data dilakukan menggunakan statistik deskriptif, uji reliabilitas, analisis korelasi, Principal Component Analysis (PCA), serta association rule mining dengan dukungan visualisasi. Hasil menunjukkan bahwa dimensi keselamatan dan efisiensi (C1) memperoleh skor tertinggi, sedangkan desain ramah lingkungan (C2) terendah. PCA mengidentifikasi tiga profil siswa: berfokus pada keselamatan, indikator alami, dan keberlanjutan. Analisis lanjutan menegaskan bahwa keberlanjutan (C4) merupakan prediktor terkuat persepsi keseluruhan, serta adanya keterkaitan erat antara desain ramah lingkungan dan keberlanjutan. Temuan ini menegaskan bahwa SSC tidak hanya meningkatkan keterampilan teknis tetapi juga menumbuhkan kesadaran keberlanjutan, sekaligus mendukung SDG 4, SDG 12, dan SDG 13.The integration of Small-Scale Chemistry (SSC) into chemistry education represents an innovative approach to supporting Green Chemistry principles by minimizing reagent use, enhancing laboratory safety, and promoting the use of natural indicators as environmentally friendly alternatives. This study aimed to evaluate how structured SSC training influenced students’ perceptions across four dimensions: safety, eco-friendly design, confidence, and sustainability. A total of 30 Grade XI students from SMA Negeri 6 Semarang participated in this training, collaboratively designed by the Department of Chemistry, FMIPA Universitas Negeri Semarang, in partnership with Sogang University and the LUPIC program. The research instrument was an 8-item questionnaire covering four competency indicators. Data analysis included descriptive statistics, reliability testing, correlation analysis, Principal Component Analysis (PCA), and association rule mining supported by visualization. The results indicated that safety and efficiency (C1) scored the highest, while eco-friendly design (C2) was the lowest. PCA revealed three student profiles: safety-focused, natural indicator–focused, and pro-sustainability. Advanced analysis showed that sustainability (C4) was the strongest predictor of overall perception, with strong associations between eco-design and sustainability as well as between natural indicators and confidence. These findings confirm that SSC enhances not only technical competence but also sustainability awareness, contributing directly to SDG 4, SDG 12, and SDG 13.

Abstract

Misconceptions in chemistry continue to challenge students' conceptual understanding, particularly in submicroscopic representations such as particle structure, solution properties, ionic interaction, and chemical reactions. This study aims to investigate the propagation of misconceptions, cluster students based on their misconception profiles, and analyze the consistency of scores about these patterns. The participants were 52 second-semester pre-service chemistry teachers who completed a diagnostic test consisting of four particle-level diagrams with open-ended questions. Bayesian Network analysis and Granger Causality testing examined probabilistic and causal relationships between misconceptions. Clustering analysis using K-Means and visualization through t-SNE identified three distinct student groups with varying misconception levels. Score consistency analysis using correlation, ANOVA, and regression revealed that misconceptions in particle structure strongly influenced errors in other concepts and were significantly correlated with lower scores (r = -0.26). Sankey diagrams demonstrated how misconceptions in early questions propagated to subsequent concepts, indicating error flow. The findings suggest that early identification and correction of key misconceptions are crucial, and clustering analysis can inform adaptive teaching strategies. This research highlights the importance of integrating causal analysis and machine learning in chemistry education research to understand better and address student misunderstanding patterns

Abstract

Growing concern about the environmental impacts of synthetic dyes has renewed interest in plant-based colorants for sustainable textile dyeing. Teak leaves (Tectona grandis Linn. f.) are rich in polyphenolic compounds with strong chromophoric properties, but the influence of fixation conditions and dye-bath pH on fabric performance requires further clarification. This study evaluated the effects of mordant type and dye-bath pH on color intensity and washing fastness of cotton fabrics dyed with teak leaf extract. Cotton samples were dyed at pH 4, 6, 8, 10, and 12, then post-mordanted using alum, ferrous sulfate, or tamarind extract. Color characteristics were quantified using the CIE Lab* system, and washing fastness was assessed following SNI ISO 105-C06:2010. Ferrous sulfate consistently produced the darkest shades and the highest washing fastness ratings (TLW 3–4 to 4), likely due to stable metal ligand complex formation among Fe²⁺ ions, dye molecules, and cellulose fibers. Mildly alkaline dye baths (pH 8–10) enhanced color depth, whereas extreme alkalinity (pH 12) decreased dye uptake, presumably because stronger electrostatic repulsion limited adsorption. Overall, teak leaf extract shows strong potential as an eco-friendly natural dye, and the results emphasize that careful mordant selection and pH optimization are essential to achieve durable coloration for sustainable textile processing.
