Abstract

Kurangnya fasilitas laboratorium yang memadai dan panduan praktikum berkualitas rendah di banyak sekolah menengah atas menghambat pembelajaran praktikum kimia yang efektif. Untuk mengatasi hal ini, penelitian ini mengembangkan dan mengevaluasi panduan praktikum kimia berbasis penyelidikan terbimbing yang terintegrasi dengan prinsip-prinsip kimia hijau, menggunakan model ADDIE (berfokus pada tahap pengembangan). Validasi dilakukan oleh enam guru kimia dan dua dosen, menilai aspek-aspek seperti konten, bahasa, penyajian, dan desain. Metode kuantitatif deskriptif dalam kerangka RD digunakan untuk analisis. Panduan tersebut menerima skor rata-rata keseluruhan sebesar 4,78 dari 5, yang menunjukkan bahwa panduan tersebut "sangat layak." Secara khusus, skor untuk konten, bahasa, penyajian, dan desain masing-masing adalah 4,78, 4,82, 4,78, dan 4,75. Hasil-hasil ini menunjukkan bahwa panduan tersebut sesuai untuk meningkatkan pembelajaran kimia praktis dan menumbuhkan kesadaran lingkungan melalui kimia hijau di sekolah menengah atas.

Abstract

This research examines the effect of the discovery learning model on higher-order thinking skills in chemistry subjects at the high school level in Indonesia with a total sample of 230 students. The research method is a meta-analysis study with a range of research data from 2015-2024 based on Google Scholar indexed by Sinta. Heterogeneity test analysis using JASP version 0.8.5 shows a τ² value of 0.236 and a τ value of 0.485, with an I² value approaching 100% (CI: 74.015%–98.358%). The results indicate a high level of heterogeneity (98.358%). Therefore, a random effects model is used in the analysis. The meta-analysis results suggest that discovery learning significantly affects higher-order thinking skills (z = 4.730; p < 0.001; 95% CI). Funnel plot and Egger's tests did not show publication bias, supported by a fail-safe N value 488. The results of this study reinforce empirical evidence that discovery learning is a practical approach to chemistry learning.

Abstract

Research on developing project-based learning materials for complexometric titration materials is still rare, despite the fact that these materials have shown promising in chemical education. The objective of this project is to create a complexometric titration learning resource based on Project-Based Learning (PjBL) and assess its viability and efficacy in improving students' psychomotor abilities and learning outcomes. Using the ADDIE paradigm, the study used a Research and Development (R&D) methodology. The media, which includes instructive videos, digital resources, and a useful mini-project, was created with Adobe Flash CS6. 42 chemical education students from Universitas Negeri Medan (UNIMED) participated in a restricted trial after validation by two subject matter experts and two media experts. Subject matter experts and media experts gave the validation results an average score of 3.29 and 3.46, respectively, which both fell into the "highly feasible" category. During the implementation phase, the experimental class outperformed the control group in terms of learning outcomes (gain score of 0.722) and psychomotor skills (average score of 3.64). With an average score of 3.46, students' reactions to the media were likewise very favorable. These results demonstrate that the developed media is useful for enhancing students' engagement in learning complexometric titration, conceptual knowledge, and laboratory skills.

Abstract

This activity aimed to enhance partners’ expertise in developing AI-based STEM-PBL learning materials, thereby advancing education, science, technology, and human resource development. It also provided training, technology application, and support to improve the quality of education through innovative learning media. Key issues identified included teachers’ low motivation to create technology-based resources, students’ lack of enthusiasm, limited technology use in chemistry classes, and teachers’ insufficient skills in utilizing digital tools. To address these challenges, strategies such as socialization, training, technology deployment, mentorship, and evaluation were implemented. These efforts focused on encouraging teachers and students to engage in problem-solving and innovative learning practices. The program’s effectiveness was reflected in the improvement of participants’ understanding, shown by an increase in the mean pretest score (51.43) to the posttest score (79.13). Thus, the objectives of enhancing mastery of the material and applying knowledge in practice were successfully achieved.

Abstract

Corrosion is a natural process of metal deterioration caused by chemical or electrochemical reactions with the surrounding environment, and it commonly occurs in iron and steel. This study examined the use of electrolysis as a simple method to reduce rust on iron surfaces by applying several electrolyte solutions. The solutions tested included sodium chloride, citric acid, acetic acid, sodium bicarbonate, and water, each at a concentration of 10%, while citric acid was also varied up to 100%. Electrolysis was performed for 10 to 30 minutes on both positive and negative poles. The findings showed that sodium chloride solution gave the highest effectiveness in rust removal, with 0.93% rust loss on the negative pole and 0.58% on the positive pole. Increasing solution concentration and treatment time further improved the rust removal rate, reaching 2.50% at 30 minutes.

Abstract

This study aims to evaluate the effect of the addition of additives in the form of sugar, salt, and flavorings on changes in temperature and type heat capacity in citric acid, acetic acid, and ascorbic acid solutions. The methodology used is a quantitative experimental approach with direct observation of temperature changes as well as calculation of enthalpy changes (ΔH) in various combinations of acidic and additive solutions. The results of the analysis showed that the types of additives exerted different effects on the thermal stability and heat capacity of each acidic solution. Sugars tend to provide the most optimal thermal stability with minimal fluctuations in ΔH change, while salts cause the greatest fluctuations. Flavorings show a more varied and inconsistent pattern of change. These findings provide in-depth insights into the thermal characteristics of organic acid solutions with additive modification, contributing to the development of applications in the fields of food, pharmaceutical, and applied chemistry education.
