Abstract

Renggak (Amomum dealbatum Roxb) shows significant potential as a natural resource with applications in various fields, particularly in environmental sensing. This capability positions Renggak as a promising candidate for developing eco-friendly chemosensors, contributing to improved monitoring of these critical anions in the environment and health. Additionally, its diverse phytochemical profile suggests potential uses in medicinal applications, further enhancing its value as a multifaceted plant. This research focuses on the characterization of the methanol extract from Renggak (Amomum dealbatum Roxb) leaves, and it's potential to detect iodide and phosphate anions. The extraction process involved soaking dried renggak leaves in methanol for 72 hours. Afterwards, the solution was filtered and evaporated, resulting in a paste-like extract. The extract was characterized using FTIR and GC-MS techniques, followed by testing its performance as a chemosensor. The paste extract was dissolved in methanol and mixed with a saturated solution of iodide and phosphate salts for the anion detection test. Then, 3 mL of each anion solution was combined with the extract, and any changes in the solution were observed. FTIR analysis revealed the presence of OH groups and C=O double bonds in the methanol extract. GC-MS analysis identified 20 compounds, with hexadecanoic acid and 9-octadecenoic acid being the most abundant. The extract demonstrated fluorescent properties in the anion detection test, acting as a chemosensor. When exposed to a UV lamp at 250 nm, the solution emitted a green fluorescent glow, indicating the successful detection of anions. These findings suggest that the methanol extract of renggak leaves could serve as an effective fluorescent chemosensor for iodide and phosphate anions.

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

This study aims to describe the readiness of science/chemistry teachers for the application of STEM learning (Science, Technology, Engineering, Mathematics) and to describe the supporting and inhibiting factors of science/chemistry teacher readiness for the application of STEM learning. This research is a descriptive research with a quantitative approach. The population of this study is the number of science/chemistry teachers who teach at SMA/SMK/MA Country in District Gerung. The sampling technique in this study used purposive sampling. The number of samples was 12 science/chemistry teachers in SMA/SMK/MA Country in District Gerung. Data collection techniques using interview guidelines and questionnaire techniques which have been declared valid and reliable. The results of the research on attitude readiness, emotional readiness, cognitive readiness and behavioral readiness in public SMA/SMK/MA Country in District showed an average gain of 74.04%. This means that the readiness of science/chemistry teachers towards the application of STEM learning is more likely to be ready. Based on this, it can be interpreted that some teachers have implemented STEM learning and have never implemented STEM learning, only to the extent that they are ready to do STEM learning. This readiness is also influenced by supporting factors such as: responsibility, enthusiasm, willingness to adapt, critical thinking, thinking contextually, aware of one's own worth and will, being able to integrate various scientific disciplines, carrying out partnership functions and being good at managing time. While the inhibiting factors are independence and awareness of strengths and weaknesses, this is because some teachers have never participated in STEM learning training and teachers have never tried to apply STEM education in science/chemistry learning. Furthermore, teachers find it difficult to improve their quality in preparation for implementing STEM learning and teachers are not yet proficient in preparing lesson plans that are appropriate to STEM learning.

Abstract

The discovery learning model is a discovery-based learning model that is needed to improve learning outcomes and student learning motivation, especially in chemistry subjects which are synonymous with calculating theories, concepts, laws and facts. This research aims to describe the influence of the Discovery Learning learning model on learning outcomes and chemistry learning motivation for class XI students at SMAN 6 Mataram. This research is quantitative research with a quasi-experimental method (Quasi Experimental Design). The results of the research show that there is an influence of the Discovery Learning learning model on student learning outcomes in chemistry subjects. This can be seen from the results of hypothesis testing with the t-test at a significance level of 5%. The calculated significance was lower than 0.05, namely 0.008 < 0.05. In learning motivation, there is also an influence of the Discovery Learning learning model on students' learning motivation in chemistry subjects, which can be seen from the results of hypothesis testing with a t-test with a significance level of 5%. The calculated significance was lower than 0.05, namely 0.01 < 0.05.
