Today we celebrate Indonesia’s 80 years of independence and the promise behind this year’s theme, Unity, Sovereignty, Prosperous People, Advanced Indonesia. At the Jurnal Optimasi Sistem Industri (JOSI), we translate that promise into practice. Unity is the coordination of people, data, and decisions. Sovereignty is supply chains designed for our archipelago so local industries can stand on their own. Prosperity is productivity that cuts waste while protecting the environment. Advancement is everyday choices made smarter by evidence.

In the fast-paced world of industrial systems, efficiency is the cornerstone of competitiveness. Companies are continually seeking ways to streamline operations, reduce waste, and enhance productivity. One of the most powerful tools enabling this transformation is simulation-based optimization, a technique that allows industries to test, refine, and implement strategies in a virtual environment before deploying them in real-world settings. This approach not only minimizes risk but also leads to data-driven, high-impact decision-making.
