Abstract

Disaster mitigation material in geography learning requires not only critical thinking skills but also independence and optimism from students. In this regard, the effective approach needed relies not only on theory but also on practice in independent assignments and exercises. It makes limited face-to-face learning, which has been applied recently, unable to optimize learning outcomes. This study aims to analyze the impact of flipped classroom learning based on disaster map visualization on students' self-efficacy and critical thinking skills in disaster mitigation materials. The study used a quasi-experimental design with a pretest-posttest control group design. The research sample consisted of the experimental class (30 students) and the control class (30 students), which were determined randomly after the equivalence test. Data on critical thinking skills were collected using a test method in 10 description items, and self-efficacy data were collected using a questionnaire consisting of 30 statements. The data were analyzed using quantitative descriptive and inferential statistical analysis with MANOVA. The results show a significant effect simultaneously or partially with the sig value. 0.05, so it can be concluded that there is an effect of flipped classroom learning based on disaster map visualization on students' self-efficacy and critical thinking skills in disaster mitigation materials.

Abstract

Immense students’ belief in misinformation indicates the less optimized quality of science education. However, research that analyzes the predictors of this problem is still rarely done. Biology knowledge (BK) depicts the level of biological information mastered by students; attitude toward science (ATS) is related to students' views when participating in science learning; while disbelief in conspiracy theories (DiCT) describes a person's ability to examine information that contradicts scientific truth. The current research was aimed at analyzing BK, ATS, and DiCT among Biology students, as well as the correlation between the three. The data collection instrument used was an online questionnaire comprising four main sections: demographic items, 15 Biology, and the General Public Questionnaire items, 40 ATS test items, and 8 DiCT items. Analysis was conducted on data from 820 respondents collected from February-March 2022. Some techniques for data analysis were applied, including frequency and percentage estimation, Kruskal-Wallis H test analysis, Dunn's test analysis, Kendall's Tau Correlation, and rank-based estimation regression. This research found that: 1) student’s ages and genders did not significantly contribute to any, while institutional status and study years did to BK and DiCT; 2) study program significantly contributed to ATS, and 3) ATS was found to not correlate significantly with DiCT, but BK was significant by the DiCT. Therefore, BK becomes the main competency that can protect students from unscientific conspiracy theories. This study has revealed a novelty framework about the position of knowledge and attitude in predicting students' abilities when examining misinformation.

Abstract

The rapid industrial growth and urbanization in Indonesia over the last two decades have resulted in a significant increase in air pollution, so it has caused a decrease in air quality. An air pollution inventory is needed to determine the level of air quality, emission sector, and the type of pollutant fuel. Air pollutant emission data were obtained from various sources, including Regional Emissions Inventory in Asia (REAS) V3.1, Database Emissions for Global Atmospheric Research (EDGAR) V4.3.2, and Community Emissions Data System (CEDS) V1.0. The data consists of 3 types of emitted pollutants (CO, NOX, and SO2) and two contributing factors (emission and fuel sectors). This study aims to compare data from the emission sources of the three air pollutants, determine the trend of changes in the emission of the three pollutants, and determine the main sectors and fuels that emit the three air pollutants. This research uses the literature study method to collect, visualize, and analyze data. The results showed that between 2005 and 2012, there was a downward trend in emissions in the industrial sector for CO, NOX, and SO2 gases, with the lowest point in August. This is because many industrial sectors have applied the principle of clean energy to reduce air pollution and create clean air. However, the transportation sector showed an increase in CO and NOX emissions and peaked in April and October. Furthermore, the SO2 emissions for the power generation sector fluctuated and peaked in July.

Abstract

This study discusses the importance of 21st-Century learning to improve students’ higher-order thinking skills and numerical literacy based on gender. This research is descriptive quantitative, and correlational. The subjects of this study were education and science students from nine public Islamic universities in Indonesia who were selected by purposive sampling and took statistics courses in the odd semester of 2021/2022 in terms of gender. The sample size is 213 students, with 87 males and 126 female students. Data collection method used questionnaires, observation sheets, and HOTS and numerical literacy tests. The results show that the 21st-century competency-based learning process to improve HOTS and numerical literacy of Public Islamic university students in Indonesia was in the very good category (81.67%). Students’ responses to the learning process were in the very good category (81.78%). Male students’ HOTS were higher than female students, and male students’ numerical literacy skills were lower than female students. In summary, these results suggest that gender partially influences and relates to HOTS and numerical literacy of students at nine public Islamic universities in Indonesia with a low correlation.

Abstract

Water hyacinth is a weed in Rawa Pening because of its rapid growth. A handling effort is a very crucial thing and must be done immediately. This study aims to characterize organic compounds in liquid smoke from dried water hyacinth. ­­­­Characterization of organic compounds from dried water hyacinth was carried out on water hyacinth liquid smoke which was pyrolyzed at 200°C and 600°C. Pyrolysis times were run at 2 hours and 6 hours. Liquid smoke from dried water hyacinth was distilled before testing its chemical composition using GCMS brand Shimadzu type QP 2010S. The results of liquid smoke characterization are used to decide that liquid smoke can be utilized as a food preservative. The test results report that the liquid smoke produced had an acid percentage ranging from 29.63% to 37.23%, phenol from 1.04 to 6.11%, and the remaining carbonyl compounds from 55.99% to 68.90%. The highest component value was obtained at 600°C pyrolysis and 6 hours. The conclusion is that liquid smoke from dried water hyacinth can be used as a food preservative because it contains acid, phenol, and carbonyl and is free of Benzo (a) pyrene, which can cause cancer. So that the requirement for liquid smoke as a preservative can be achieved, whereas acid is a food preservative. This study generates the acquisition of natural food preservatives to utilize weeds. The research helps us utilize weeds to resist the Rawa Pening environment and manufacture food preservatives.

Abstract

During the pandemic of COVID-19, online learning was introduced, and the students' achievement decreased. This research aimed to find the effect of the biology learning model by using real objects (RO), ICT, and Blended Learning (BL) on students’ factual and conceptual knowledge. The research design was a quasi-experiment with a pretest and posttest comparison group design. This research was done in two senior high schools. Cluster random sampling was used to choose three groups of RO, ICT, and BL, involving two biology teachers and 139 students. The instrument was mainly tests of factual and conceptual knowledge. The test items were validated by expert judgment and an empirical test. Multivariate analysis was applied to test the difference in the effect of the three learning models. The results indicate that (1) RO gives the highest students’ achievement in factual knowledge, (2) ICT increases students’ conceptual knowledge, and (3) BL improves both factual and conceptual knowledge. Therefore, it is concluded that learning biology should use RO and ICT through BL to improve factual and conceptual knowledge.

Abstract

This study aims to describe the problem-based learning and collaboration model on science learning in elementary schools in the Industrial Revolution era 4.0 and Indonesia Society 5.0. This research is qualitative and descriptive. Data collection activities at the preliminary stage are carried out by exploring elementary school teachers' perceptions of problem-based learning and its application in science learning in schools in Surakarta, Indonesia. Focus group discussions (FGD) were conducted on 20 elementary school teachers employing the open inquiry method. The discussion reviewed several topics related to the teachers’ perception of the problem-based learning application, the advantages and disadvantages of problem-based learning as the basis for modifying the learning model, and the importance of collaboration skills for elementary school students. The problem-based learning-collaboration (PBL-C) model is a development of the problem-based learning model, which is equipped with collaborative skill indicators from the Industrial Revolution 4.0 aspects and coordination indicators with various parties from Indonesia Society 5.0 aspects. The result of this research is the problem-based learning-collaboration (PBL-C) model design with six steps: (1) orientation of students to problems, (2) organizing students for learning and division of tasks, (3) guiding investigations on local community leaders, (4) proving the results of the investigation, (5) developing and presenting the work, and (6) analyzing and evaluating the problem-solving process.

Abstract

This study aimed to investigate grade-11 students’ conceptual understanding of chemical reaction rate through 5E inquiry approach in which they were asked to explore data for answering the engaged question using the small-scale syringe-vial experiment (SSVE) and elaborate their understanding using the AR interactive Particulate-level Visualization (ARiPV). The two-tier diagnostic conceptual test and semi-structured interview questions served as the data collection instruments. Thirty-three grade-11 students cooperated in the series of four 2-hour 5E learning activities for a total of 8 hours. Dependent samples T-test analysis showed that the mean score of the postconceptual test (mean 29.77, S.D. 6.77, 66.16%) was statistically greater than that of the preconceptual test (mean 11.68, S.D. 10.14, 25.96%) at the significance level of 0.05. Their actual gain was 40.20% and their normalized gain was 0.54, a medium increase. The majority of them moved from the less correct category, Partial Understanding with Specific Misunderstanding (PMU, 43.03%), to the more correct category, Partial Understanding (43.84%). The semi-structured interview showed that the 5E inquiry technique using SSVE in conjunction with ARiPV was entertaining and successful in identifying and enhancing their understanding. This demonstrated that this integrated intervention can encourage students to shift their conceptual understanding of reaction rate to the more advantageous categories.
