Abstract

This study aims to determine the mastery of vector arrangement and decomposition on students' abilities in the matter of Newton's laws. In collecting data for this research, tests were given on the material of vector arrangement and decomposition and the material of Newton's laws. This test is to see the ability in mastery of the learning materials above. Data analysis shows that there is an influence of mastery of vector arrangement and decomposition on students' abilities in Newton's laws of matter. The results of the calculation of the correlation coefficient obtained an r value of 0.86 and continued with the significance test of the correlation coefficient, the t value was 9.70 which was greater than the t table value, which was 1.694. In the calculation of the coefficient of termination obtained a value of 0.7427. This result shows 74.27% which shows that there is a contribution of mastery of vector arrangement and decomposition to students' abilities in Newton's laws of matter.

This study aims to determine the effect of the discovery learning model on students' mathematical critical thinking skills. This study uses the Quasy experimental method with a Nonequivalent Control Group Design. Sampling was carried out using the Purpose sampling technique so that students from classes VIII-2 and VIII-3 were selected as the control class and 32 people from the experimental class were selected. The instrument used in the form of an essay test of 5 items that have been declared worthy. Both samples have met the test data requirements and are declared to meet the requirements of normality and homogeneity. Furthermore, to test the hypothesis using the T-Test, the results show that there is an influence of the discovery learning model on students' mathematical critical thinking skills on number pattern material in class VIII of SMP Negeri 5 Pematangsiantar

Abstract

This study discusses a mathematical model for the transmission of influenza virus in the human body. The mathematical model used is the SITR model. As an effort to inhibit the influenza virus, the model is considered as herbal treatment therapy.The purpose of this study was to analyze the stability of the equilibrium point of the mathematical model of the influenza virus in the human body with herbal medicine therapy. The method used in analyzing the problem is literature study. The steps taken are determining the problem, literature study, analysis and problem solving and drawing conclusions. As a result of the research, the model obtained is. . From this model, there are two equilibrium points, namely the disease-free equilibrium point and the endemic equilibrium point. The analysis carried out resulted in the basic reproduction ratio number . After analyzing the two equilibrium points, it can be concluded that the disease-free equilibrium point will be locally asymptotically stable if . Meanwhile, the endemic equilibrium point will be locally asymptotically stable . Furthermore, to illustrate the model, a model simulation is carried out using the Maple.

Abstract

This study aims to describe the development of risk management in MAN 2 Padangsidimpuan Model. Risk management aims to manage these risks so that we can obtain the most optimal results. In this study, researchers used descriptive research methods. This research method is a method that seeks to reveal the facts of an event, object, activity, process, and human as it is at the present time or a period of time that is still possible in the respondent's memory. The research location is at MAN 2 Model Padangsidimpuan which is located at Jalan Sutan Soripada Mulia No. 29. The results show that the development of risk management in MAN 2 Padangsidimpuan Model is the entire Madrasa risk management process that must be monitored, and if necessary modifications are made. In this way, the system can react dynamically, changing according to existing conditions. Monitoring is carried out through ongoing management activities, separate evaluation of the Madrasah risk management process is a combination of the two.
