Abstract

This research aimed to produce practical guiding products that are suitable for use and to know the students' responses to the products developed. Research & Development (R&D) was used as a form of research which was referred to the 4D model by Thiagarajan, but the implementation of the model just limited a 3D level. Subject tested the students of Chemistry Education FKIP Untan who had taken kinetics chemistry courses. Data collection tools used were validation sheets and student response questionnaires on the product developed. The results of the expert judgement obtained interpretation is very feasible in terms of aspects of content feasibility, presentation feasibility, linguistic feasibility, and graphic feasibility with consecutive total scores is 97%, 95%, 96%, and 96%. Students' responses to the results of small group trials were 81% with high interpretation and in large group, trials were 81% with very high interpretation.

Abstract

The aims of this research were to determine the feasibility of Development Electronic Worksheet (e-worksheet) based on Project Based Learning on geometry molecule by the results of expert judgments and student responses on the results of field trials. The form of this research is research and development (R&D) which adopts Kemp's development model. The subject of this research was Electronic Worksheet (e-worksheet) based on Project Based Learning on geometry molecule which was tested at 27 students of SMAN 10 Pontianak. The instruments of data collections were the feasibility questionnaire and student response questionnaire. The results of data processing showed that the e-worksheet that developed was suitable for use in learning in terms of the percentage of content material, presentment, linguistic, and media respectively 96.6%; 96.8%; 90.2% and 86.1%. The result percentage of the calculation student questionnaire responses to the material aspects was 83.33%, 79.31%  to linguistic aspects and graphical aspects was 89.50%. Based on the average of the three aspects of student responses, it was found that the percentage of e-worksheet based on Project Based Learning on geometry molecule subject was 84.04%, which was included in the very high category.

Abstract

Morus alba L species, usually known as mulberry, have a distinctive color, namely blackish purple. This color is caused by the presence of anthocyanin compounds which are color pigments. Anthocyanin compounds have the potential to be used as indicators of acid base. This study aims to determine the pH, solubility and shelf life trails of acid-base indicator films from chitosan-based mulberry fruit extracts. The method used is extraction by maceration, through immersion of mulberry fruit that has been refined using 96% ethanol solvent. Determination of the pH route using an acetate buffer solution with a pH of 1-14. The solubility of acid-base indicator film can be seen by immersing the indicator film in water for 24 hours, weighing it to a constant and comparing it to film that is not immersed in water and calculated the value of FS% (film solution). The shelf life of the indicator film was observed using a microscope to find out whether there was mold growth on the surface of the film. The results of the study showed that the pH of the acid-base indicator film strain of mulberry fruit extract, namely, pH 1-3 were red, and pH 10-14 were green. Based on data analysis, the percentage of the solubility of the acid-base indicator film of mulberry extract was 40.18%, which means that the indicator film with mulberry extract was hydrophilic so that it was easily dissolved in water compared to without the mulberry extract of 22.2% which had lower solubility values. Durability for 30 days was observed in the absence of growth of microorganisms / fungi on the surface of the indicator film.

Abstract

This aims of this research is to determine whither there is a significant difference at of achievement between students before and after learning using refutation text based worksheet ant to effectiveness refutation text based worksheet on reducing misconceptions on topic hydrocarbon. The form of research used was pre-experimental with a one-group pretest-posttest research design. Samples were taken from class XI MIPA 4 which consisting of twenty nine students through purposive sampling technique. Data were collected using multiple choice diagnostic test with three alternative answers and three alternative reasons consisting of 15 questions. Acoarding to analusis, there is a differences in achievement between students were tested using the Wilcoxon test and an Pvalue who less the 0,000 which meant there was a significant difference. Acoarding to propotions test the effectiveness score 0,61 which was as category medium. Acoarding to analysis, there was a decrease in the percentage of students' concept errors by 47.4%. Conclude there is a significant different of achievement before and after remediation with medium effectiveness.

Abstract

This study aims to provide a bibliometric analysis of course-based undergraduate research experience from 2010-2023. Data were extracted from the Scopus database and analyzed using VOSviewer. A total of 67 related publications were analyzed and mapped. According to bibliometric analysis, course-based undergraduate research experience, inquiry-based learning, and upper-division undergraduate become the center of the topic in the study of course-based undergraduate research experience in chemistry. It also shows that collaborative/cooperative learning, discovery learning, problem-solving/decision-making, first-year undergraduate, organic chemistry, and chemical education research. are among the novel and emerging topics in course-based undergraduate research in chemistry. This research is expected to provide a better understanding of the challenges and opportunities of studying course-based undergraduate research experience in chemistry.
