Sustainable Supply Chain Strategy of PT. Barru Mandiri Nusantara for Blue-Green Economy in Eastern Indonesia

The increasingly volatile global business environment, marked by macroeconomic turmoil and geopolitical shifts, necessitates that companies integrate sustainability principles into their operations. This study analyzes the sustainable supply chain strategy of PT. Barru Mandiri Nusantara, a key water treatment chemical supplier in Eastern Indonesia, as it navigates global trade dynamics and contributes to the blue-green economy. Using a qualitative single case study design, data were collected through in-depth interviews and document analysis. The findings were subsequently analyzed using SWOT analysis and the Quantitative Strategic Planning Matrix (QSPM).The results indicate that PT. Barru Mandiri Nusantara has strengths, such as an extensive distribution network, but also faces critical weaknesses, including a high dependency on imported raw materials. The company operates amidst significant opportunities, like the growing demand for clean water, yet is vulnerable to threats from global raw material price volatility. The QSPM evaluation revealed that the most attractive strategies involve leveraging internal strengths to expand into environmentally friendly products and forging strategic partnerships with government entities. The study concludes that these strategies are crucial for enhancing the company's business resilience and its proactive role in fostering water sustainability within the region. Managerial recommendations include diversifying raw material suppliers, investing in integrated supply chain information systems, and actively developing environmentally friendly products. For future research, multi-case studies or quantitative approaches are suggested to expand generalizability.
