Abstract

Unemployment, investment, and the economy are three interrelated aspects that significantly influence a country's economic development, including Indonesia. A high unemployment rate negatively impacts people's purchasing power and economic growth, whereas investment plays a crucial role in job creation and boosting national productivity. Indonesia's economy continues to evolve amid various challenges, including global economic instability, policy changes, and labor market dynamics. Therefore, the government strives to address these issues through fiscal and monetary policies that support investment climate improvement and promote inclusive and sustainable economic growth. This article discusses the relationship between unemployment, investment, and the Indonesian economy, as well as the strategies that can be implemented to achieve economic stability and prosperity for society.

Abstract

This study aims to analyze production theory in the long run using the isocost and isoquant approach as graphical and analytical tools. In long-run production theory, all inputs are considered variable, allowing firms to adjust the combination of production factors to achieve maximum efficiency. The isoquant approach illustrates various combinations of inputs that produce the same level of output, while the isocost line represents combinations of inputs with the same total cost. The optimal production point is reached when the isoquant curve is tangent to the isocost line, indicating the input combination that minimizes cost for a given level of output. This study highlights that understanding these concepts is crucial for production managers and decision-makers in designing cost-efficiency strategies and improving productivity. Through this approach, firms can achieve an efficient and sustainable production equilibrium in the long run.
