This journal aims to establish Papua as the window of Indonesia's spirit for the Melanesian communities. Using a comprehensive qualitative literature review approach, the research analyzes strategies that address geopolitical dynamics, resource competition, cultural and technological impacts, regulatory frameworks, and implementation processes. The article acknowledges challenges in historical grievances, governance, infrastructure, environmental risks, and social cohesion in both Indonesia and Papua. To unlock Papua's well-being and security, several key initiatives are proposed. These initiatives include preserving cultural heritage, improving education and healthcare, developing infrastructure and tourism, promoting regional cooperation, and ensuring equitable benefits for indigenous Papuan communities. Emphasizing drivers of competitiveness such as innovation, research, human capital, and regional integration, the research identifies sectors with growth potential, such as natural resources, agriculture, renewable energy, tourism, and manufacturing. To fulfill Indonesia's global role, an outward-oriented strategy that prioritizes cultural values, economic progress, environmental conservation, maritime collaboration, and diplomatic engagement is recommended. Successful implementation of these strategies is expected to enhance regional stability, increase prosperity, improve cooperation, and achieve inclusive and sustainable development in Papua. The article provides recommendations for strengthening national identity, preserving cultural diversity, empowering local communities, enhancing education, promoting social cohesion, ensuring environmental sustainability, and strengthening global partnerships. By implementing these initiatives, Indonesia can effectively navigate geopolitical dynamics, unlock Papua's economic potential, and foster inclusive growth. This research aligns with the vision of Indonesia Golden 2045, promoting a harmonious, prosperous, and inclusive environment.
