This research is an experimental study with a type of True Experimental research. The design carried out in this study was the design of the pretest-posttest control group design. Determination of the sample using a random sampling system while the data-collection technique was using test, that are pre-test and post-test. The class XII AK 1 as the experimental class 1 (video media) and class XII AK II (powerpoint media) as the experimental class 2. The normality test data was analyzed by using the pretest value on the use of video media with a significant level of 0.388 and on the use of a significant level powerpoint media of 0.059, it was stated that the two significant levels were normally distributed because they were greater than 0.05 . The homogeneity test results show that a significant level of pretest for both classes (video media and powerpoint media) is 0.436 and more than 0.05. It also shows that the sample used has the same or homogeneous variance. The results of the statistical test with the Independent Sample T-test showed a significance level of 0.001 <0.05, indicating that the results of the t-test <significance level of 0.05. In addition, it is known that tcount is 2.093 which indicates that tcount ˃ ttable (2,093 ˃ 0.408). So the hypothesis H0 is rejected and H1 accepted. So it can be concluded that there are differences in student learning outcomes using video media using powerpoint media.

Indonesia is one of the most densely populated countries in the world so that this country has a population of productive age. However, Java Island has several provinces with varying unemployment rates. This study uses secondary data obtained from the Central Statistics Agency and via the internet to complete the data. The analytical method used in this research is multiple linear regression with the help of Eviews software. The results showed that the education and investment variables consisting of foreign investment did not have a significant effect on the unemployment variable and investment which consisted of domestic investment had a significant effect on the unemployment variable through the t test. The coefficient of determination (R2) is 0.3686, which means that 36.9 percent of the variation in unemployment in Java can be explained by variations in the 3 independent variables, namely economic growth and unemployment, while it is explained by other variables not mentioned in the research model.   Keywords: Education , Investment, Unemployment Rate.

The purpose of this study, among others, is to determine the effect of consumer satisfaction and promotion on shopee consumers' repurchase intentions during the pandemic.

The sampling technique of this research is the saturated sampling technique, which means using the entire population as a sample so that 57 students are obtained. This study uses multiple regression analysis. With a questionnaire as a data collection tool and tested for validity and reliability as well as the classical assumption test as a test instrument. The data that has been collected was analyzed by SPSS. The results showed that there was a partial positive effect of consumer satisfaction on repurchase intentions. There is a partially positive effect on promotion on repurchase intention. There is a simultaneous effect of consumer satisfaction and promotion on repurchase intention.

This study aims to analyze the improvement of student learning outcomes by applying the jigsaw type cooperative learning model on the introductory subjects of economics and business basic competence of production costs. This research is a Classroom Action Research. Subjects and location is the students of class X Accounting 3 SMK Sejahtera Surabaya. Learning tools consist of syllabus, Learning Implementation Plan, learning material, Student Worksheet, and post test sheet. While the instrument used is a student observation sheet. The results showed that student activity increased 9.52% from cycle I 76.19% to 85.71% in cycle II. Students classical completeness increased by 16.22% from cycle I 64.86% to 81.08% in cycle II. It shows that jigsaw type cooperative learning model can improve learning outcomes on introductory subjects of economics and business students of class X Accounting 3 SMK Sejahtera Surabaya.
