Abstract

Purchasing power parity (PPP) theory states that the exchange rate between two currencies should reflect the comparative prices of goods and services in both countries, and this study focuses on the effect of exchange rate, monetary policy, and inflation. In this study, secondary data is used to see how domestic and foreign inflation correlates with the Rupiah exchange rate. The results of the analysis show that there is a significant correlation between inflation and the exchange rate, which suggests that appropriate monetary policy is needed to maintain exchange rate stability and people's purchasing power. It is hoped that this research will help policymakers make plans to tackle inflation and increase people's purchasing power.

Abstract

The application of problem-based learning approaches to mathematics subjects in elementary schools needs to be improved. It is proven through literature review research that this problem-based learning approach has a significant positive effect on optimizing mathematics learning in achieving maximum learning targets for students in class IV SD. The method used in this research is a systematic literature review to review journals and articles related to PBL and math learning outcomes. Data was collected from the Google Scholar database using a method based on PRISMA, the application of the learning model proved to be effective in problem-based learning in Cycle I resulted in an average percentage of student learning outcomes showing a significant increase from 60% in Cycle I to 89% in Cycle II. This shows a percentage increase of 29%. This research concludes that PBL is an effective method to optimize mathematics learning in surpassing maximum learning targets for students in elementary school. Increasing the application of this problem-based learning approach in the application of mathematics lessons in elementary school is very important and needs to be done on an ongoing basis.
