Abstract

Exchange rate of the Indonesian Rupiah against the US Dollar is a crucial economic indicator that significantly impacts Indonesia's macroeconomic stability. Exchange rate fluctuations can affect trade, investment, inflation, and monetary policy. Therefore, an accurate forecasting method is essential to support economic decision-making. This article aims to evaluate the effectiveness of Moving Average and Exponential Smoothing methods in predicting the Rupiah exchange rate against the US Dollar. Using a qualitative approach based on literature review, this study compares findings from various previous studies on these two methods. The analysis results indicate that Exponential Smoothing is more effective in highly volatile market conditions due to its adaptability to trend changes, while Moving Average performs better in stable market conditions. These findings provide insights for academics, financial analysts, and policymakers in selecting appropriate forecasting methods to support economic stability.

Abstract

Indonesia ranks second in global instant noodle consumption, reaching 14.26 billion servings in 2022, making product quality control a central concern for industry players. This study examines how Total Quality Management (TQM) principles are applied within Indonesia’s instant noodle industry and their relation to maintaining competitive advantage. A literature review method was used with a qualitative descriptive approach and content analysis of relevant academic sources. The study found that applying seven TQM elements, namely top management commitment, customer orientation, continuous improvement, employee involvement, production process control, supplier relationship management, and data-based decision making, contributes meaningfully to production efficiency, defect reduction, consumer trust, and global market competitiveness. This study offers a conceptual framework linking TQM, Quality Control, and Competitiveness specifically within the Indonesian instant noodle industry context, an area that has received relatively limited academic attention. Keywords: Total Quality Management (TQM), Quality Control, Industrial Competitiveness
