Abstract

The two stay two stray learning model is a cooperative learning model that provides opportunities for groups to share knowledge and learning experiences with other groups, where in the group there are group members who stay to share the material obtained and group members who visit other groups to find information about the material obtained in the group. This study was conducted to determine whether using the two stay two stray learning model can improve student learning outcomes, especially in the material of Two Variable Linear Equations. The posttest type experimental design used in this study was posttest only control group design. The sampling technique is simple random sampling (simple random technique). The subjects in this study were class VIIIB students as an experimental class consisting of 22 students and class VIII A students as a control class consisting of 22 students at SMP Negeri 3 Motoling Timur, these two classes were randomly selected. Data were obtained from the learning outcomes of experimental and control class students.

Abstract

Planning helps monitor activities. to achieve the expected efficiency and effectiveness. In advertising planning at GMS Digital Marketing, there are often losses. The purpose of this study is to find out how to manage good time in advertising planning in GMS Digital Marketing and find out what efforts can be made so that advertising planning has efficient time. A mathematical approach called Critical Path Analysis (CPM) is used to organize the grouping of project operations. The project activities described using the CPM Method are a two-round procedure consisting of a forward and backward approach to setting a schedule when conducting a critical path analysis. ES and EF are set up during the forwarding process. During the transfer, LS and LF are determined. Early Start (ES) is the fastest way to start an activity. CPM is a cost-cutting approach for projects. We can know when costs and schedules need to be negotiated to meet project deadlines while keeping costs as low as possible. When a dimension is used, then CPM is used. (More accurate time estimates). Therefore, from the results of this study, a critical path is obtained that requires additional labor and time in completing the work

Abstract

This study aims to examine the relationship between the angle of deviation and the average time length of a physical pendulum. This study uses primary data, namely practicum report data in a physics laboratory. Data collection was conducted under closed conditions with control variables (shaft length, number of oscillations, and radius of gyration) and dependent variables (angle of deviation and average time). The analysis technique used is a statistical approach technique, namely Latin Square Design analysis. The findings of this study indicate that the variables of deviation angle and average time on the physical pendulum have a strong and unidirectional correlation relationship. This result is evident from the value of F0 > Fcritical and the value of Pr (> P) > 0, 05(significant level) where both of these prove that there is a strong reason to reject H0 which means that there is at least 1 difference in the effect of the angle of deviation on the average time. It shows that the angle of deviation affects the average time of the physical pendulum

Abstract

This study focuses on the effectiveness of clustering algorithms, namely Fuzzy C-Means by using k-Means algorithm as a supporting method, in the factors that cause Diabetes Mellitus. Diabetes mellitus is a chronic disease characterized by high levels of sugar (glucose) in the blood. Indonesia ranks 5th with the highest diabetes Mellitus patients in the world. This study aims to understand the pattern of factors causing Diabetes Mellitus and test the effectiveness of the clustering algorithm used. The data analysis methods include data collection, data pre-processing, distribution of cluster numbers, algorithm implementation, model adjustment, model training, model evaluation, and analysis of results. The results showed that the Fuzzy C-Means algorithm gets a coefficient of Fuzzynes score of 0.23 with a validation score of 0.40, while for supporting methods used K-Means algorithm gets a validation score of 0.32. This result shows that Fuzzy C-Means algorithm is superior in clastering the factors that cause Diabetes mellitus. The results of what variables have the most effect on cluster values 0 and 1. Where cluster 0 is a cluster that shows which variables are more at risk of diabetes, while cluster 1 is a cluster whose value shows what variables are far from the risk of causing diabetes mellitus. Then based on the results of the cluster that has been done, random blood sugar variables become the most influential variable on the risk of developing diabetes mellitus, followed by blood sugar variables 2 hours PP, and fasting blood sugar

Abstract

Unemployment is one of the indicators for measuring the economic conditions of a region. It is also a social and economic problem in many countries, including Indonesia, especially in areas with a density of economic activity, such as Java Island. The purpose of this study was to classify and analyze the factors that affect the open unemployment rate in cities and regions on Java Island, which are categorized as low, medium, and high. The research method used in this study was ordinal logistic regression analysis. The data source comes from the BPS website in 2023 with four predictor variables: population size, labor force participation rate, average years of schooling, and gross regional domestic product at constant prices. The research results show that the variables population size and labor force participation rate had a significant effect on the open unemployment rate, while the variables average years of schooling and gross regional domestic product at constant prices did not have a significant effect on the open unemployment rate with the accuracy of the ordinal logistic model is 77.27%.
