Abstract

Monetary policy is a key instrument in maintaining a country's economic stability. An imbalance between the money supply and inflation can negatively impact economic growth, purchasing power, and price stability. This study analyzes the role of monetary policy in controlling inflation and money supply to promote stable and sustainable economic growth. The study employs a qualitative approach by analyzing secondary data from central bank reports, previous research, and relevant macroeconomic data. The findings indicate that monetary policy instruments, such as interest rates, open market operations, and reserve requirements, are effective in curbing inflation while maintaining economic growth. However, the effectiveness of these policies depends on global economic conditions and the real sector's response to monetary policy changes. Therefore, a flexible and data-driven policy is required to adapt to economic dynamics. These findings provide implications for policymakers in designing more adaptive monetary strategies to achieve long-term economic stability.

Abstract

Cost theory is one of the fundamental concepts in economics that explains how firms allocate resources to produce goods or services. In economic analysis, costs are categorized into short-run and long-run costs. In the short run, there are inputs that are fixed, limiting the firm's ability to adjust the scale of production. This leads to the concepts of fixed costs and variable costs. In contrast, in the long run, all inputs are variable, giving firms full flexibility to adjust their scale of production, which results in the formation of the long-run cost curve. This curve serves as an envelope of various short-run cost curves and reflects production efficiency at different scales. Understanding the differences between short-run and long-run costs is essential for firms in making decisions, particularly in production planning and long-term investment.

Abstract

This study aims to analyze the effect of motion graphic learning media in improving student responses to inflation material at SMA Negeri 12 Medan. This study employed a quantitative approach using simple linear regression analysis to determine the relationship and influence between motion graphic learning media and student responses. The research sample consisted of 35 students selected as respondents. Data collection was conducted through questionnaires that had previously been tested for validity and reliability using IBM SPSS Statistics. The results showed that the research instruments met the validity and reliability requirements, with Cronbach’s Alpha values of 0.893 for the motion graphic learning media variable and 0.880 for the student response variable. The Pearson correlation test indicated a strong positive relationship between motion graphic learning media and student responses, with a correlation value of 0.771 and a significance level of 0.000. Simple linear regression analysis revealed that motion graphic learning media contributed 59.4% to the improvement of student responses, while the remaining percentage was influenced by other factors outside this study. The hypothesis testing results showed that the t-value of 6.944 was greater than the t-table value of 2.034 with a significance value of 0.000 < 0.05, indicating that the research hypothesis was accepted. The increased use of motion graphic learning media has proven to have a positive and significant effect on student responses to inflation material at SMA Negeri 12 Medan. The use of motion graphic learning media is capable of increasing students’ interest, attention, participation, and engagement during the learning process, thereby creating a more effective and interactive learning environment.
