Abstract

This study examines the relationship between interest rates, inflation, and investment, as well as their impact on economic growth. High interest rates tend to hinder investment by increasing capital costs, while uncontrolled inflation can create economic uncertainty that negatively affects investment decisions. Based on the Fisher Effect concept, the nominal interest rate is the sum of the real interest rate and the expected inflation rate, indicating that changes in inflation directly influence central bank interest rate policies. An analysis of various journals reveals that interest rates have a negative relationship with investment, while inflation can have both positive and negative effects depending on its level. If inflation remains stable, investment tends to increase; however, if inflation is too high, purchasing power declines, and investors seek safer assets. On a macroeconomic scale, healthy investment is a key factor in driving economic growth, as it contributes to job creation and increased production. Therefore, a balanced monetary policy is essential to maintaining inflation stability, interest rates, and investment growth to ensure sustainable economic development.

Abstract

Low student interest in learning economics has become the underlying phenomenon behind this study. In an effort to address this issue, the research focuses on examining the effectiveness of implementing the Problem-Based Learning (PBL) model as the basis for developing learning media, particularly in the context of the topics of payment systems and payment instruments. Methodologically, this study adopts a quantitative approach with a descriptive design. Data collection was carried out through the distribution of questionnaires consisting of 30 Likert-scale statement items to 32 respondents. The quality of the instrument was tested through two stages: a validity test, which showed that all items met the required criteria with correlation coefficients ranging from 0.444 to 0.821, and a reliability test, which produced a Cronbach’s Alpha value of 0.956, indicating excellent instrument consistency. The assumption of normality was confirmed through the Kolmogorov-Smirnov test, which yielded a significance value of 0.079 > 0.05. Based on the analysis conducted, it was found that the integration of PBL-based learning media was significantly associated with an increase in students’ learning interest. The problem-based approach proved effective in encouraging active participation, fostering analytical thinking patterns, and enhancing students’ enthusiasm for learning in understanding concepts related to payment systems and payment instruments.
