Abstract

This study aims to explore the chemistry aspects of local practices on Mango (Mangifera indica L.)fruit ripening process with calcium carbide to be integrated in contextual chemistry learning.Literature studies from scientific journals related to natural and artificial fruit ripening werecomparatively analyzed in relation to local knowledge and scientific concepts to identify potentialintegration into science learning (especially chemistry). The results showed that the integration ofnatural science with local practices, such as fruit ripening, is an innovative way to teach chemicalkinetics in a contextualized way. The study of the fruit ripening process can help students understandchemical concepts, especially chemical kinetics, in a more relevant and practical context. Thus,chemistry learning is not only limited to theory and laboratory experiments, but also includes realapplications that are relevant to the lives of students and society.

Abstract

This research aims to explore the biochemical aspects of the local wisdom of the Honai traditional house Dani tribe of Papua and its potential integration in biochemistry learning through an ethnoscience approach. The research method is literature study from scientific journal articles, books, online articles, and research reports related to the biochemical composition of the building materials that make up the Honai traditional house.  The main problem in this study is how to construct indigenous science knowledge into scientific science and identify its potential integration in biochemistry learning. The study showed that the main components of Honai houses are reeds, various types of wood, and rattan. The biochemical composition is lignin, holocellulose, alpha-cellulose and hemicellulose as well as other compositions that can be discussed on the topic of biochemical aspects of living things and further on the topic of cells and cell bonds / chemical bonds. The material composition contained in the materials that make up the honai traditional house can also be further explored in the practice of applied biochemistry, to produce other appropriate items. Thus the Honai traditional house is highly potential as a learning resource in biochemistry courses with an ethnoscience approach.

Abstract

This program evaluation is intended to describe the results of the comprehensive examination program for prospective teachers in all science fields. The results of this program evaluation are expected to make a specific contribution to the sustainability of the comprehensive examination program being held and are expected to contribute to education in general. This program evaluation uses the CIPP (Context, Input, Process and Product) evaluation model. Data sources for this program evaluation consist of documents and human resources. Based on the results of a thorough evaluation of the comprehensive examination program, it can be concluded that recommendations to improve the effectiveness and sustainability of this program are very important. Evaluations covering context, input, process and product aspects show that there are several areas that need to be improved and improved. An effective and sustainable comprehensive examination program is not only an evaluation tool, but also an integral part of their academic and professional career development. With a holistic and sustainable approach, study programs can ensure that comprehensive exams provide maximum benefits for students and educational institutions as a whole.

Abstract

Telang flowers are found in many tropical areas, one of whuch is in Indonesia. The content of telang flowers can be used as anticancer, anti-inflammatory and antimicrobial. The amount of healt potential contained in telang flowers is important to do standardization. This study aims to determine the standardisation of telang flower extract in maceration method with 96% etanhol, ethyl acetate and n-hexane solvents. Standardisation testing includes specific and non-specific parametes. The results showed that the telang flowers used was included in the Clitoria ternatea species. Weight yield, drying shrinkage, specific gravity, moisture content and ash content have met the standard. The largest yield weight is found in ethanol solvent which is 11.83%. The highest secondary metabolite content was found in ethanol solvent, namely alkaloids, flavonoids, tanins, and saponin. While in n-hexane solvent there were only terpenoids and steroids.

Abstract

The philosophy of science serves as a framework for understanding and teaching scientific knowledge, including metabolism, to promote health and prevent chronic diseases such as kidney failure. This study aimed to explore students' perspectives on kidney failure among young adults and the implications of the philosophy of science in metabolism education. A qualitative case study approach was employed, involving six science education students in East Java. Data were collected through in-depth interviews and analyzed thematically. The findings reveal that students have positive experiences with metabolism education, enhancing their understanding of metabolic processes and their role in kidney health. The program also encourages lifestyle changes, such as increased healthy food consumption and physical activity. However, challenges such as limited access, academic stress, and inadequate facilities persist. Students demonstrate a high awareness of kidney failure, although some perceive their risk as low. This study highlights the importance of inclusive, community-based education approaches and the use of digital technology to amplify its impact.

Abstract

This study examines the significance of Pedagogical Content Knowledge (PCK) in chemistry education, specifically its role in pre-service chemistry teacher training. Through a comprehensive review of 14 articles, the research identifies key themes related to the development, application, and impact of PCK on chemistry teaching practices. The majority of the articles emphasize the importance of integrating PCK into teacher training programs, highlighting the effectiveness of practice-based and constructivist learning approaches to bridge the gap between content knowledge and teaching strategies. PCK was found to influence teaching methodologies, allowing teachers to tailor their approaches to specific chemistry topics and manage classroom dynamics effectively. However, the study also reveals significant gaps in the application of PCK in classroom management and assessment practices, areas that require further exploration. The findings suggest that although PCK plays a critical role in improving teaching quality, its integration into classroom management and assessment is still underexplored. The research recommends future studies to focus on these areas, particularly in secondary and higher education settings, to refine the application of PCK across various aspects of chemistry teaching. This research contributes to a deeper understanding of PCK's role in teacher preparation and offers directions for future research to enhance the development of pre-service chemistry teachers and improve overall teaching effectiveness.
