Abstract

The learning of chemistry requires practical activities to assist students in understanding chemical concepts deeply and also to connect scientific principles with everyday life. However, practical activities often face challenges such as inadequate equipment and materials in laboratories, posing a challenge for educators to conduct practical-based learning. This article proposes the development of natural pH indicators based on bacterial cellulose to enhance acid-base learning in schools. These natural pH indicators are formulated by combining plant-based natural indicators with (Biocellulose) and immersing them in buffer solutions ranging from pH 1 to 14. The color changes produced by these natural pH indicators based on bacterial cellulose indicate different pH levels, serving as a reference for each solution measurement.These indicators are used in classroom learning during acid-base topics in the 11th-grade science classes. Stimulates curiosity and interest among teachers and students, leading to more engaged observations during the experiments.Overall, teachers and students perceive these natural pH indicators based on bacterial cellulose as effective tools for conveying acid-base concepts and enhancing engagement in practical-based learning methods.

Abstract

This study aims to analyze the influence of the Problem-Based Learning model on the development of students' critical thinking skills and environmental concern through meta-analysis research. Meta-analysis was carried out on 33 relevant national and international articles. Data collection was carried out through a systematic literature search on academic databases such as Sinta, Scopus, Web of Science, Google Scholar, and Eric Journal. Based on the results of the study, it showed an increase in the average pretest score of 67.09 to 80.98 on the posttest, as well as the size effect (ES) which ranged from 0.66 to 0.89. Data shows that the application of PBL is able to improve students' analytical thinking skills while fostering awareness of environmental issues. PBL, as an authentic problem-solving-based model, has a significant positive impact with consistent results at various levels of education, both secondary and tertiary. This study also identifies factors that support the success of PBL, such as learning design, the quality of interaction between students and teachers, and the relevance of the context of the problems presented. With an average error standard of ≈ 0.05, the results of this study have a high level of reliability. These results have important implications for the development of education policies to integrate the PBL model in the curriculum to improve students' critical thinking skills and environmental concerns. This study concludes that PBL is an effective learning strategy in shaping students who are not only intelligent, but also care about environmental sustainability.       Keywords: meta-analysis, problem-based learning, critical thinking, environmental awareness.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1480-1497

Abstract

Family is the smallest unit in society that significantly contributes to protecting family members, one of which is protecting and preventing sexual violence against children and adolescents. The family intervention model (FIM) is a family-based intervention model through efforts to change cognitive, affective, and behavioral aspects. This model seeks to impart knowledge and change parents' behavior concerning the issue of sexual violence in children and adolescents through the application of the family intervention model. This research used a quasi-experimental mixed-method with both quantitative and qualitative approaches. This study found that the paired sample t-test statistically showed that family intervention model contributed to changes in parental behavior toward sexual violence (p-value = 0.000). The results of the regression analysis showed that the family intervention model helped bring bout changes in family behavior toward sexual violence in children and adolescents, by 64%. It is importance to improve the role of parents in increasing communication and assertiveness within the family as a preventive measure against sexual violence.
