Abstract

In the context of environmental chemistry learning, ethnoscience can be used to connect scientific concepts with cultural values. This learning helps students understand the importance of environmental conservation through a relevant and contextual approach. This study aims to identify the ethnoscience of Peringgesela weaving as a learning resource for Environmental Chemistry. The subjects of this study were Peringgesela weaving craftsmen. The research methods were observation, interview and documentation. The results showed that natural dyes such as tarum, mengkudu, and turmeric contain active compounds that represent chemical concepts such as redox reactions, acid-base, and extraction. In addition, the fixation process using synthetic fixation materials such as alum with the molecular formula KAl(SO4)2, lime Ca(OH)2 and tunjung (FeSO4) with waste that is directly disposed of in the surrounding waters. The absence of waste management shows the basic principles of environmental chemistry. The integration of ethnoscience in learning resources for Environmental Chemistry allows students to understand science concepts more contextually, relevantly, and deeply.

Abstract

Understanding the urgency of the material and the main aspects of the essential concepts of science is very important in learning. This study aims to analyse the urgency of the material and the main aspects of the essential concept in learning Natural Sciences (IPA) in the Independent Curriculum at the junior high school level. The Independent Curriculum provides flexibility for educators in designing contextual learning that is relevant to the needs of students, so that the selection of essential materials becomes very crucial. This study uses quantitative descriptive analysis with a simple random sampling technique on science teachers in Mataram City. Data was collected through a Likert-scale questionnaire to measure the level of urgency of science materials and the essentiality of aspects of the learning process. The results showed that most of the science materials, such as "Substances and Their Changes", "Life Organization Systems", and "Energy and Its Changes" were categorized as very urgent, with an average score of 3.44. In addition, aspects of the science learning process, such as "science-based problem solving", "science project development", and "science literacy skills", were also considered very essential, with an average score of 3.40. However, there are two materials with a moderate level of urgency, namely "Electricity and Magnetism" and "Human Reproductive System". Meanwhile, only one aspect of learning is considered essential (not very essential), namely "application of science in everyday life". This finding indicates the importance of adjusting the curriculum and learning strategies to ensure optimal achievement of competencies. Recommendations are directed to curriculum developers and educators to focus on materials and aspects of learning that best support students' scientific literacy and 21st-century skills.

Abstract

Science education plays a critical role in shaping students' scientific literacy and attitudes. Teachers' perspectives on the nature of science (NoS) are central to how science is taught in classrooms, particularly at the elementary level. This study aims to analyse the views of elementary school teachers in Indonesia on the fundamental characteristics of science and how they implement these views in their teaching practices. Using a descriptive quantitative approach, complemented by Focus Group Discussions (FGD), data were collected from 52 teachers across diverse geographical regions, including West Nusa Tenggara, Java, and East Nusa Tenggara. The data were analysed based on four core aspects of the nature of science: science is interesting to study, science is useful in life, science continues to develop, and science is a global human endeavour. The results show that most teachers have very positive views on the first three aspects, while their understanding of the global dimension of science is categorised as good. Further analysis revealed no significant differences in teachers' views based on length of service, gender, or PPG (Teacher Professional Education) status. These findings suggest the need to enhance teachers' pedagogical competence through globally oriented training programs and contextualised science teaching approaches. This study contributes to improving the quality of science education by encouraging a more holistic and globally relevant understanding of science among primary school teachers.

Abstract

Sumbawa oil is a traditional medicine renowned for its efficacy in treating various ailments. This oil continues to be produced today using a variety of spices. Most of the production residue comes from coconut milk curd (blondo). The caramelization process of blondo produces a sweet flavor. This residue is then processed into high-value snack products. Dodal is tested organoleptically to ensure the taste, color, and aroma of the spices in the product are pleasant to consume. This testing is conducted to ensure the quality of the dodal due to high-temperature heating. Dodal is packaged in ready-to-eat packaging, making it convenient for use and storage. This processing ensures that the oil residue (in the form of dodal) has a long shelf life for extended storage and adds economic value to the local community.
