<![CDATA[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.]]>

<![CDATA[This study describes students' adaptive reasoning abilities in solving HOTs type questions in Kolb's learning style. The method used to determine students' adaptive reasoning ability in solving HOTS (Higher Order Thinking Skill) uses qualitative research with a descriptive approach and type questions regarding learning styles (diverger, assimilator, converger, and accommodator types). The research subjects were thirty-five students of class XI. The results of data analysis and discussion can be concluded that students of class XI MIPS-3 SMA Negeri 4 Pasuruan have adaptive reasoning abilities in solving solutions to the HOTS type questions through the Polya step in terms of Kolb's learning style. Students who have adaptive reasoning ability solve the HOTS type problem solving through the Polya step in terms of Kolb's learning style. Students with a converger type of learning style can meet all indicators of adaptive reasoning ability (propose conjectures or conjectures, provide reasons or evidence about the truth of a statement, draw conclusions from an idea, check the validity of an argument, and find patterns from a mathematical problem) and all indicators in the Polya step (understand the problem, make a plan, implement the plan and re-examine the results).]]>

<![CDATA[The study's purpose is to describe the cognitive conflicts experienced by students with relational understanding when solving the problem of three-term ratios. The current research is a case study with a qualitative approach using a purposeful sampling technique. The three research objects are representations of the condition that (1) the student was sure of his solution (cognitive conflict was solved) and the solution is correct, (2) the student was confident with his solution (cognitive conflict was solved) but the solution is not correct, and he is not confident with the solution (cognitive conflict was not solved), and the solution was not correct. The results of this study describe students with relational understanding experience cognitive conflicts, that is, being aware of the conflict between the initial concepts they have and the results obtained. Students feel doubtful and worried, as indicated by the awareness that the initial scheme applied to one proportion problem cannot be applied to other comparison questions. Students' cognitive conflicts with relational understanding do not always lead them to get the correct solution to the three-term ratio problems. The reason is that the student believes comparison is wrong (misconception).]]>

<![CDATA[In modern Industrial Technology 5.0, educators are challenged to develop the ability to create learning media for use with technology support. Comics are very popular among teenagers, including high school students. One type of comic is digital comics, which was once a global trend that served as an effective learning medium. This type of research is research and development (R & D) using 3D research methods (definition, design, development). In this study, researchers were limited to the definition stage. The equipment used in this study was a questionnaire to analyze the needs of Class X teachers and students and nine math teachers in MAN2 Malang. Based on the results of the survey conducted, it can be concluded that students need digital comic learning media based on Islamic values of inverse functional materials. This is based on data that 81.7% of respondents strongly agreed and 83.5% of teachers strongly agreed that it was necessary to develop digital comic learning media based on Islamic values in order to motivate them to learn]]>

<![CDATA[The data revolution in medical records has increased the automation of medical devices in determining the factors that cause any disease, but it also poses challenges to their analysis. According to WHO, about 6% of the world's population of more than 420 million people live with type 1 or type 2 diabetes and this number has estimated to rise beyond half a billion by 2030, which means that one of the ten adults in the future is suffering from diabetes. With the rapid development of machine learning, machine learning has been applied to many aspects of medical health. In this study, we used Decision Tree C4.5 to predict diabetes mellitus. This research used a diabetic dataset obtained from UCI machine learning repository with 419 instances and 16 attributes. In this dataset, mostly of attributes are numeric types that are continuous. This research results of the improved C4.5 algorithm by applying PCA. Many algorithms have been proposed to overcome misclassification and overfitting on classifications Decision Tree C4.5. Feature reduction is one option that is intended to eliminate irrelevant data and overcome outliers in the data so as to increase classification accuracy. Based on the results of the experiment, the application of PCA in C4.5 resulted in an increase in accuracy of 6.55% were achieved.]]>

<![CDATA[The research problem was how the steps for analyzing the needs of interactive learning media based on multiple intelligences integrated with Islamic values developed. This study describes the Needs Analysis of Interactive Learning Media based on Multiple Intelligence integrated with Islamic values. This type of research was qualitative research. This research was conducted to analyze the need to create interactive learning media, Inspiring Presentation, with HTML5. The method of collecting data in the research was by using interview techniques on six students of class VII and three teachers of Mathematics. Based on the needs analysis and the material analysis results, no interactive learning media contains nine multiple intelligences, which we know as Multiple Intelligences integrated with Islamic values. So it is necessary to develop further from the results of this study to get to the stage of obtaining good learning media as needed.]]>

<![CDATA[Crude oil has a vital role in the economic growth of a country because crude oil is a source of energy driving the economy. To maintain economic stability, the price of crude oil in the coming period needs to be anticipated by making predictions on world crude oil commodity prices. One of the models that can be used to predict crude oil prices in the short term is Geometric Brownian Motion (GBM). This study aims to implement the GBM model to predict crude oil prices during the Covid-19 pandemic and measure the model's accuracy. This study made crude oil price predictions with several iterations of 50, 100, and 1000. The results showed that the smallest MAPE value was carried out 1000 times in iterations, namely 2.13%. Based on the MAPE value, it can be concluded that the results of crude oil price predictions using GBM have a high level of accuracy.]]>
