Pre-Service Chemistry Teacher’s Conception About Chemistry of The Rare Earth Elements

Rare Earth Elements (REE) is an interesting chemistry topic, especially due to current technology development. However, new learning designs of REE need to be developed for Pre-service Chemistry Teachers (PCT) as it is not yet available. A good design is constructed by analyzing PCT pre-conceptions based on the technical difficulties faced by the students during teaching process. The study aims to identify PCT's pre-conceptions focusing on REE topic. We conducted this research involving 17 chemistry education students at the Universitas Pendidikan Indonesia, Bandung. Data was collected through interviews and analyzed using the Qualitative Content Analysis (QCA) method. Our results highlight that PCT had difficulties with chemistry content of REE, especially about electronic configuration, magnetic, and luminescence properties. In addition, PCT faced difficulties correlating electronic configuration's chemistry content into contexts. Based on the interview results, 88.2% of the students agree with the development learning design for undergraduate chemistry students. As a result, we conclude that technical difficulties and misconceptions about REE can be overcome by developing the learning design based on the need of the students.

PENGARUH PERMODALAN, AKTIVA PRODUKTIF DAN LIKUIDITAS TERHADAP PROFITABILITAS BANK RAKYAT INDONESIA SYARI’AH PERIODE 2010-2018

This research was conducted with the aim of examining the effect of capital, earning assets and liquidity on profitability at Syari'ah Bank Rakyat Indonesia. In its analysis capital is represented by the Capital Adequacy Ratio (CAR), earning assets are represented by Non Performing Financing (NPF), liquidity is represented by Financing to Deposit Ratio (FDR) and profitability is represented by Return On Equity (ROE). The data analysis technique used is multiple linear regression analysis. The results of this study indicate that partially CAR has a negative and significant effect on ROE, which means that capital has a positive and significant effect on profitability, then NPF has a negative and significant effect on ROE. profitability, then FDR has a positive and significant effect on ROE, which means that liquidity has a negative and significant effect on profitability. While simultaneously CAR, NPF and FDR have a significant effect on ROE, this means capital, earning assets and liquidity together have a significant effect on profitability

SCIENCE, ENGINEERING, AND TECHNOLOGY OF DYE SENSITIZED SOLAR CELLS: A DIDACTICAL DESIGN BASED ON TECHNOCHEMISTRY EDUCATION

This research was conducted to build a view of the nature of science and technology (VNoST) chemistry education students' ability through the didactical design reconstruction. The material taken is Dye-Sensitized Solar Cells (DSSCs) topic with technochemistry education model. It is a model that looked at education from the perspective of engineers and scientists who work not only on inquiry but also on a design perspective. Based on literature research, Indonesian students had low academic literacy performance as revealed in PISA (Program for International Student Assessment) study from 2000-2015. This problem can be caused by a weak teacher's abilities of the nature of science and technology (VNoST). This research's method is Research and Development (R&D) through the Model of Educational Reconstruction (MER). The instruments used were the VNoST questionnaire, interview guidelines, and content analysis guidelines. This study's subjects were 25 prospective chemistry education students in the 6th semester for pre-conception study and ten students for implementation study at one of State Universities in Indonesia. The didactical design of learning that has been developed had several advantages, including the prediction of student responses and the anticipation of educators as well as the essential material that is a barrier to student learning. Analysis of the VNoST understanding construction patterns is explored further so that the reasons that underlie students in defining science and technology and their relationship are obtained. The implementation study proved that understanding VNoST students after attending didactical design learning improved by changing students' views on science and technology to be more accurate

A Bibliometric Analysis of Publications on Systems Thinking in Chemistry Education using Vosviewer,

This study utilizes a bibliometric approach along with computational mapping analysis. This study employs a bibliometric approach, complemented by computational mapping using VOSviewer, to explore systems thinking research in chemistry education. The primary goal is to identify key research themes and trends in this field. The initial step involved searching for articles with keywords like "systems thinking" and "chemistry education" using the Publish or Perish software and Google Scholar database. This yielded 922 articles, which were carefully selected based on specific criteria. The comprehensive analysis included co-authorship, co-citation, co-occurrence, cluster, and content analysis using VOSviewer. The quantitative analysis highlights the significance of publications related to systems thinking in chemistry education and broader educational contexts. Over the past decade, prominent themes emerged, including sustainability education, design thinking, outcomes assessment, critical systems, climate change, and more. Qualitative insights further emphasize the relevance of understanding systems thinking in chemistry education, influencing pedagogical approaches and research initiatives.

Development of Social and Culture Aspects Pre-service Science Teachers on Learning for Nature of Science

Understanding aspects of the Nature of Science (NOS) for preservice science teachers is one of the essential components to be able to understand Science and its processes. There are seven aspects of NOS: empirical, inference, creative, latent theory, tentative, scientific procedural myths, theories and laws of science, social and cultural dimensions, and their embedding in science. There are 48 preservice science teachers involved in this study. Researchers explored their views about NOS and Indigenous Knowledge (IK) through a validated questionnaire. Results showed that the students' opinions on NOS consisted of empirical, tentative, inference, law, scientific theory, and creativity. Meanwhile, aspects of laden theory, myths of scientific procedures, and social and cultural dimensions embedded with science have not been described by students. Fortunately, the students presented IK as an authentic context based on the culture in science learning.  Students express IK ideas: 1) biomedicine (40 students), Biopesticide (2 students), beauty ingredients (2 students), additives (1 student), and supernatural medicine (1 student). Integrating Science and IK as an authentic context in science learning leads IK toward high technology and strengthens NOS aspects. In addition, the assumption that IK has no future is declining

Explorative Research Course: Recovering Rare Earth Elements from Electronic Waste Using Deep Eutectic Solvents

This study aims to demonstrate how a course design approach based on explorative research involving systems thinking can be implemented by recovering Rare Earth Elements (REEs) using Deep Eutectic Solvents (DES). The method used in this research is Design-Based Research (DBR). The instruments used were questions regarding the measurement of leaching samples from results/characterization, short questions about concept maps, and student response questionnaires. Data from measurements of leaching samples was measured using a Fourier Transform Infrared Spectrometer (FTIR), data about concept maps was measured by the number of component and process concepts in the context of electronic waste recycling that students were able to identify, and student response data was measured using a Likert scale. Based on the research results, recovery of REEs can be done using DES. It can be shown by a shift in the peak vibration of 497.65 cm-1 from the sample before leaching to a vibration of 449.43 cm-1 after leaching. In addition, this study yields new insights into the perceptions of future pre-service chemistry teachers regarding the possibility of new types of DES in the context of chemistry learning. According to pre-service chemistry teachers, recovering REEs from electronic waste and applying DES are interesting as a new context for laboratory learning. Context-based design of research activities can enhance system thinking and interest in chemistry. The results of study showed increased student’s systems thinking abilities, as shown by the component and process concepts that emerged from the pre-test by 652 concepts while the post-test increased by 1208 concepts
