The study background is the need to evaluate learning and the placement of the sequence of courses. The learning objectives are achieved optimally. This study conducts a path analysis to determine the direct or indirect effect of learning outcomes for mathematics prerequisite courses, Discrete Mathematics and Linear Algebra and Matrix, on learning outcomes of Expert Systems with Artificial Intelligence as an intervening variable. This study is explanatory research conducted at the Study Program of Informatics Engineering, STMIK Palangkaraya. The sample used is the 2017 and 2018 batch of students who have taken and passed the MD, AL, KB, and SP courses, as many as 94 people. The data were analyzed using student learning outcomes in the four courses. The data were then selected and analyzed descriptively, the assumption of path analysis (normality, multicollinearity, and heteroscedasticity) was tested, and finally, path analysis was performed. Hypothesis testing was carried out with the help of the R program. The results showed (1) the learning outcomes of the MD and AL courses directly significantly affected the learning outcomes of the KB courses by 23% and 23.7%, respectively, and (2) the learning outcomes of the AL courses directly affected the learning outcomes of the SP courses by 34.9%, (3) the learning outcomes for MD and KB courses do not directly affect learning outcomes for SP courses, (4) learning outcomes for MD and AL courses do not indirectly affect learning outcomes for SP courses.

Cognitive flexibility is the ability to think openly and be able to solve problems from different perspectives. People who have good cognitive flexibility will be able to learn faster, solve problems more creatively, and adapt and respond to new situations more effectively. This research method is a quantitative method of measuring the ability of cognitive flexibility as measured by questions that meet the indicators of cognitive flexibility with the object of research being the sixth semester student of one of the universities in the city of Bandung. The instrument consists of cognitive flexibility questions, theories about cognitive flexibility, and questionnaires. Processing of data by calculating the percentage of answering the questionnaire and scores of cognitive flexibility test scores in complex analysis courses. The results of the study showed that the ability to think openly, and many ideas and ideas about something was still low and the two abilities had a low correlation with lecture outcomes. So that the ability to think openly, and many ideas and ideas need to be improved so that students have an open mind and find new ideas in solving problems

The Open Unemployment Rate is the number of unemployed from the total labor force in an area or region in the form of a percentage. In Tuban Regency, unemployment has experienced a very significant increase from 2019 to 2020. Therefore, it is necessary to make predictions in 2021 and 2022 to find out the description of the Open Unemployment Rate in that year so that actions can be taken by the government to deal with this. By using the Backpropagation method, this study obtained predictions that in 2021 it will be 4.58% of the total workforce in Tuban Regency in 2021 and in 2022 the open unemployment rate will be 4.7% of the total workforce in Tuban Regency in 2022, with network architecture 2-70-1-1, the learning rate used is 0.1 and the MAPE value is 8.363%. The test was stopped at the 276th epoch. At the time of testing between the output and the target there was a correlation (R) of 0.993 where the best result was 1.

This study aims to analyze the effect of Flipped Classroom learning on the mathematics learning outcomes of blind students during the Covid-19 pandemic. This type of research is Quasi-Experimentals with Nonequivalent Control Group Designs. The population used in this research is the blind students of class V and class VI of SLBN ABD Kedungkandang Malang city with 12 students. Samples were taken using a saturated sampling technique. The experimental class uses the Flipped Classroom learning model for class VI students, and the control class uses a direct learning model as a comparison, namely for class V students. The data results show Normal and Homogeneous with the resulting significance value > 0.05. Then the final test is the independent sample t-test to determine whether there is a difference in the average of the two unpaired samples from the data. Depending on the first decision by observing the column value Sig.t count (2-tailed) or P-value, required if the value of Sig. t-count 0.05, then H0 is accepted, and if the value of Sig. t-count 0.05, then H0 is rejected. From the second decision, H0 is rejected, and H0 is not enough to be accepted. The results showed that learning mathematics with the Flipped Classroom learning model for blind students in the covid-19 pandemic had a more positive effect than the results of learning mathematics in a direct learning class or without any treatment with the Flipped Classroom model.

This study is a mixture of quantitative and qualitative with sequential explanatory designs. The study aims to (1) analyze the improvement of student achievement in learning after scaffolding, (2) evaluate the level of students 'mathematics anxiety, and (3) describe the role of scaffolding in changing students' perceptions of mathematics anxiety in classroom learning. Sampling through random sampling techniques obtained by students of class X-IPA-1 and X-IPA-2 in SMA Negeri 6 Semarang. Quantitative data analysis uses statistical test techniques: normality test, paired sample t-test, and N-gain test. Qualitative data analysis through interactive methods namely data collection, data reduction, data presentation, and drawing conclusions. Data validation techniques through the source and method triangulation. The results showed that (1) there was an increase in student learning achievement after the application of the scaffolding strategy by 33.0% to 34.5%; (2) there was a decrease in the level of mathematics anxiety in students by 90.4%; (3) through scaffolding, students succeed in reflecting and correcting mistakes in solving previous problems. This means scaffolding can be an effective strategy to help students move across different Zones of Proximal Development (ZPD). The scaffolding strategy has also created a positive classroom environment that encourages students to learn mathematics without fear.

This study is expected to contribute to the health sector, specifically to describe the dynamics of the measles spread through the models that have been analyzed. One of the factors that became the focus of this study was reviewing the influence of population density on measles spread. The initial step formulated the model and then determined the primary reproduction number and analyzed the stability of the model equilibrium point. The results of the analysis of this model show that there are two conditions for the value of which is a requirement that the existence of two model equilibrium points as well as local stability is needed, namely and . When , there exists a unique equilibrium point, called the non-endemic equilibrium point denoted by . Conversely, when , there are two equilibrium points, namely and the endemic equilibrium point characterized by . The results of local stability analysis show that when , the equilibrium point is stable asymptotic locally. It means that if hold, then in a long time there will not be a spread of disease in the susceptible and vaccinated sub-population, or in other words, the outbreak of the disease will stop. Conversely, when equilibrium point is stable asymptotic locally. It means that if , then measles disease is still in the environment for an infinite time with the condition of the proportions of each sub-population approach to , , and .
