Abstract

The study aims to determine the effect of the flipped classroom learning model assisted by pre-class quizzes on student learning outcomes of the Faculty of Mathematics and Natural Sciences, University of Mataram, in the subject of biochemistry, on fatty acid metabolism. The type of experimental research used in this study was a Quasi-Experimental Design with a Post-Test Only Non-Equivalent Control Group Design. The population in this study was the sixth-semester students of the Faculty of Mathematics and Natural Sciences, Mataram University, for the 2022 academic year, totaling 60 people with a sampling technique using saturated sampling. In this research, two classes were used: the control and experimental classes. In the experimental class, namely class A, the flipped classroom learning model was treated with the help of pre-class quizzes, while the control class only used the flipped classroom model without pre-class quizzes. This study measured student learning outcomes from post-test question scores with 30 multiple-choice questions. The data analysis techniques used are normality test, homogeneity test, hypothesis test using paired sample t-test, and effect size test. Based on the results of data analysis using the normality test and homogeneity test that was carried out, the data was usually and homogeneously distributed, so hypothesis testing was carried out using the t-test and effect size test. Based on the hypothesis testing that has been carried out, there is an influence of the flipped classroom learning model assisted by pre-class quizzes on student learning outcomes in the biochemistry course on fatty acid metabolism. This can be seen from the sig value. (2-tailed) of 0.000 in the paired sample t-test, resulting in the interpretation that H0 is rejected and H1 is accepted. As for the magnitude of the effect of the flipped classroom model assisted by pre-class quizzes using the effect size calculation formula, the result was 1.33, which shows the criteria for a high effect value.

Abstract

This study aims to identify the chemical concepts contained in the process of making coconut oil, then the results of the identification and documentation are compiled into a chemistry magazine for senior high schools. The process of making coconut oil is done by two methods, namely heating/traditional and fermentation. The preparation of a chemical magazine is carried out using the method according to Borg & Gall which is simplified into five stages, namely preliminary studies, planning, initial product development, field implementation tests, and product finalization. There are several chemical concepts related to the process of making coconut oil, namely macromolecules, mixture separation, boiling point elevation, and colloids. Magazine feasibility testing is done by validating and analyzing student responses. The results showed that the magazine developed was very valid with an average value of V on the components of graphics, content feasibility, presentation feasibility, and magazine language respectively 0.92, 0.91, 0.96, and 0.88. The results of the student response analysis show that the developed magazine is very feasible with an average percentage of 90%.

Abstract

This study aims to determine the effect of Augmented Reality media on the conceptual understanding of eleventh-grade students at SMAN 1 Pujut on the topic of acids and bases. The research design used is a quasi-experiment with a nonequivalent control group design. The population for this study consists of tenth-grade students at SMAN 1 Pujut. The research sample includes class XI F1 as the experimental group (23 students) and class XI F2 as the control group (20 students). The learning outcome instrument is a post-test in the form of multiplechoice questions. Quantitative data analysis was performed to test the hypothesis using a t-test. The results show that the calculated t-value (3,84) is greater than the table t-value (2.01), which means that the null hypothesis (H₀) is rejected, and the alternative hypothesis (Hₐ) is accepted. The results of the student response questionnaire to the application of Augmented Reality learning media on acid-base material showed that the number of students who stated Strongly Agree (SS) was 44%, Agree (A/S) was 34%, Disagree (D/TS) was 17%, and Strongly Disagree (SD/STS) was 5%. Thus, the average percentage of Strongly Agree and Agree choices was 78%. Therefore, it can be concluded that there is an effect of using Augmented Reality media on the conceptual understanding of eleventh-grade students at SMAN 1 Pujut.

Abstract

Learning difficulties are obstacles that hinder students from achieving optimal academic performance. This study aims to analyze the learning difficulties encountered by Grade XI students in chemistry and to identify the contributing factors. The research employed a descriptive method with a qualitative approach, involving 70 students from MAN 1 Central Lombok as research subjects. Data were collected using questionnaires, interview guides, and students’ test scores. The research instruments were validated by three expert validators, yielding a validity score of 0.88, indicating a high level of validity, and tested for reliability using Cronbach’s Alpha, which confirmed their consistency. Data were analyzed descriptively by calculating the percentage of learning difficulties based on specific indicators or criteria. The findings revealed that students faced major difficulties in calculation-based materials (60%) and theoretical concepts (54.06%). Interviews were conducted to strengthen the data obtained from the questionnaires. The contributing factors were categorized into internal factors, external factors, and learning approaches, with internal factors being the most dominant at 59%. This study is expected to serve as an evaluation material for teachers and schools in designing more effective and context-based learning strategies in chemistry education.
