Abstract

This study analyzes the learning loss of first-year students' chemistry concepts at FKIP, University of Mataram. The research sample was 112 first-year students taking introductory chemistry courses at FKIP University of Mataram, 14 male students (12.5%) and 98 female students (87.5%)—these students, as a whole, face two years of online learning in high school. The primary data in this study is the analysis of respondents' test results related to prior knowledge of chemistry concepts during one semester of lectures. The results showed that the idea of limiting reagents and percent composition showed the highest learning loss (53.57%), while the concept of moles and molar mass and matter showed the lowest learning loss percentage of 32.14%. Furthermore, the results of statistical tests show the relationship between the average score before the UTS implementation and after the UAS implementation. The previous lack of online learning to strengthen students' prior knowledge indicates the cause of learning loss in chemical concepts. Questionnaire analysis stated that education through WA groups, the duration of chemistry learning was low, and the lack of feedback given by teachers on assignments students were working on during the learning process strengthened the current conditions.

Abstract

The Organic Compound Mechanism and Synthesis Lecture (MSSO) is one of the important courses in the chemistry education study program, which discusses the process of forming organic compounds through various chemical reaction. The limited learning media used, which is only in the form of textbooks, also causes the learning process to be less interesting. Therefore, an interesting and easy to understand learning media innovation is needed. This research aims to develop a reading supplement in te form of a chemical magazine with formaldehyde condensation content as supporting media for MSSO lectures, as well as to determine the level of validity and feasibility. The research methode used is research and development (R&D) with a 4D (define, design, develop, disseminate) model. The result of the validation of the chemical magazine by 3 (three) validators showed a validity coefficient value of 0,93 with a very valid category, and a reliability value of 95%. Student responses to chemistry magazines showed a very practical category with a score 84.98%..

Abstract

Mastering the interpretation of spectra, as Gas Chromatography-Mass Spectrometry (GC-MS) spectra, in organic chemistry lectures for the analysis of natural materials is an important skill that often poses a challenge for students. This is especially true for natural materials in the surrounding environment that may have future potential, such as renggak fruits. This study aims to determine the results of interpreting renggak fruit peel extracts for use as content in a chemistry magazine, the level of validity, and student responses to the chemistry magazine developed as an alternative supplementary reading material. Conducted within the Chemistry Education Study Program at Mataram University, this study utilized the Research and Development (R&D) methodology, following the 4D model framework. The interpretation of the GC-MS spectrum of renggak fruit peel was carried out by matching the spectrum data obtained with the library data. The validity of the magazine was assessed using Aiken's V formula, while the reliability of the assessment was calculated based on the Percentage of Agreement (R) between validators. Student responses to the magazine product were obtained through a practical test. The results of the GC-MS spectrum interpretation of the renggak fruit peel extract showed the presence of the compounds myristic acid, palmitic acid, stearic acid, oleic acid, elaidinsaeure, heptadecene- (8)-carbonic acid-(1), 2-monoolein, 2-monopalmitin, ambretollide, 6-(2,6,6-Trimethyl-1-Cyclohexenyl)-4-Methyl-(E)-4-Hexen-1-ol, and cis-9-Octadecenal. The chemistry magazine product obtained an average Aiken's V validity score of 0.83, which falls into the “Highly Valid” category, with an average validator reliability score of 91%. The results of the chemistry magazine trial among 2021 Chemistry Education students obtained a practicality score of 92%, categorized as “Very Practical” as supplementary reading material. In the future, further exploration is needed regarding the content and design of the magazine to be created.

Abstract

Research and development were conducted with the aim of describing the chemistry concepts contained in the traditional gold mining culture in Prabu village, Middle Lombok and gold crafts in Sekarbela, Mataram. This research is a qualitative descriptive study with a survey approach, conducted in collaboration with 4D Research and Development. The data in this study were collected using the triangulation method, which included interviews, observations, and literature studies. The data analysis technique employed the Miles and Huberman method, which involved data reduction, data presentation, and drawing conclusions. The results of the study indicate that in the traditional gold mining culture in Prabu Village, Middle Lombok, and the gold craft cultural activities in Sekarbela Mataram, there are chemical concepts, including elemental chemistry, reaction equations, oxidation-reduction reactions, the application of the solubility product of salts to separate chemical components from their mixtures, the concept of acids and bases, and the concept of colloids. Teaching materials in the form of ethnochemistry magazines from research and development have a feasibility category that is very feasible, based on the magazine's size, cover design, and content design, with an average V coefficient of 0.94. The feasibility of ethnochemistry magazines, based on the material component indicator, with sub-indicators of material suitability and stimulating curiosity, as well as the feasibility of presentation, with sub-indicators of presentation techniques and presentation support, and the linguistic component indicator, is classified as very feasible, with an average V coefficient of 0.93. In general, ethnochemistry magazines from research and development are classified as very feasible, with an average V coefficient of all aspects of 0.935.

Abstract

Chemistry magazines have the potential to be effective media because they are able to present material in a more interesting, concise manner, and are supported by visualizations that clarify abstract concepts. The use of chemistry magazines is expected to help students deepen their understanding of the aldol condensation reaction mechanism and other organic materials. This study aims to develop a chemistry magazine that contains content on the cross-aldol condensation reaction mechanism as a supplementary reading for students in the Polyfunctional Organic Compounds course. The type of research used is research and development (R&D) with a 4D model that includes the stages of define, design, develop, and disseminate. The subjects of the study were students from the Chemistry Education Study Program at the University of Mataram, while the object of the research was a chemistry magazine developed based on the results of a student needs analysis. Data were collected through expert validation sheets and student response questionnaires, then analyzed descriptively and quantitatively using Aiken's V formula to measure validity and percentage of agreement (PA) to measure reliability. The results showed that the chemistry magazine obtained an average validity score of 0.93, categorized as “highly valid,” and a reliability level of 94%, categorized as “reliable.” Meanwhile, the results of the practicality test, as obtained by students, achieved a percentage of 85% with the category “very practical”. Thus, the chemistry magazine developed is declared feasible and practical for use as additional reading material to enhance students' understanding of the cross-aldol condensation reaction mechanism in the Polyfunctional Organic Compounds course and to foster an interest in learning chemistry independently.
