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 examine the impact of digital learning media on students' motivation by analyzing findings from various credible journal articles. As technology advances, digital tools have become a crucial component of modern education. The research employs a systematic literature review method, synthesizing empirical evidence from recent educational journals. The results indicate that digital learning media—such as e-learning platforms, educational videos, interactive applications, and digital simulations—significantly enhance students' motivation by providing dynamic, engaging, and accessible learning experiences. However, its effectiveness depends on factors like teachers' technological proficiency, infrastructure availability, and students' readiness for digital-based learning. The study concludes that while digital learning media holds great potential in boosting motivation, its successful implementation requires appropriate teaching strategies and adequate support systems.
