Abstract

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.

Abstract

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.

Abstract

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 .
