This study aims to see how students from different classes perceive the e-Module Mathematics Physics I on vector material, besides that variations in gender differences will also be tested in this perception. The type of research used is descriptive quantitative research. The population in this study were students of Physics Education class 2019 with a sample of 80 students in regular classes A and C. The data were analyzed descriptively and inferentially by using the IBM SPSS Statistic 22 application which consisted of descriptive test, normality test, homogeneity test, and t-test analysis. The results obtained are normal data with a sig of 0.190, and homogeneous with a sig of 0.305. While the t-test obtained a sig value of 0.019 for gender differences in class A, and 0.017 for gender differences in class C. So Ho is rejected and Ha is accepted, meaning that there are significant (significant) differences in perceptions based on gender in each class A and C. Where the perception of male students is higher than the perception of female students, but overall students give a good perception of the Mathematics Physics e-module I on Vector material.

Mathematics physics is often considered by students as a very difficult subject to learn, one of the causes that makes this happen is the lack of learning media that supports students. In addition, most of the existing media use foreign languages, so that in this case Indonesian language learning media is needed, namely the mathematical physics e-module on vector material which is then seen from student responses based on gender differences. This study aims to analyze students' perceptions of the mathematics physics e-module and to analyze students' perceptions based on gender differences in the mathematics physics e-module. This type of research is survey-based research with a quantitative approach. The population of this study was physics education students who contracted mathematical physics with a sample of 80 students. The instrument used in this study was a student perception questionnaire with 15 questions and an interview sheet with 10 questions. The data analysis technique used in this research is descriptive statistical analysis and inferential data analysis using t-test. The results showed that overall students had a positive perception with a perception value of 60% in the very good category and 40% in the good category, whereas when viewed from the gender difference, male students had a perception value of 76.6% in the very good category and 23, 3% in the good category, for female students 50% in the very good category and 50% in the good category. That is, students with gender differences have striking differences in perceptions. Student perceptions can be used as a determining factor in the selection of open materials. From the results, it can be seen that gender differences can help in assessing the products made so that they will support the learning process and increase student learning motivation.

“…In the literature, this value should be less than 0.05. It states that if the p-value is less than the value of alpha 0.05, this means has a significant difference and strong correlations [42]. PM 10 is a complex mixture in a solid or liquid state with a molecule larger than 0.0002 µm and smaller than 500 µm in the atmosphere or a gas mass.…”

Evaluation of Air Quality Index by Spatial Analysis Depending on Vehicle Traffic during the COVID-19 Outbreak in Turkey

et al. 2021

As in other countries of the world, the Turkish government is implementing many preventive partial and total lockdown practices against the virus’s infectious effect. When the first virus case has been detected, the public authorities have taken some restriction to reduce people and traffic mobility, which has also turned into some positive affect in air quality. To this end, the paper aims to examine how this pandemic affects traffic mobility and air quality in Istanbul. The pandemic does not only have a human health impact. This study also investigates the social and environmental effects. In our analysis, we observe, visualize, compare and discuss the impact of the post- and pre-lockdown on Istanbul’s traffic mobility and air quality. To do so, a geographic information system (GIS)-based approach is proposed. Various spatial analyses are performed in GIS with the statistical data used; thus, the environmental effects of the pandemic can be better observed. We test the hypothesis that this has reduced traffic mobility and improved air quality using traffic density cluster set and air monitoring stations (five air pollutant parameters) data for five months. The results shows that there are positive changes in terms of both traffic mobility and air quality, especially in April–May. PM10, SO2, CO, NO2 and NOx parameter values improved by 21.21%, 16.55%, 18.82%, 28.62% and 39.99%, respectively. In addition, there was a 7% increase in the average traffic speed. In order for the changes to be permanent, it is recommended to integrate e-mobility and sharing systems into the current transportation network.
