This study investigates the potential of utilizing post-mining areas for sustainable melon (Cucurbitales, Cucurbitaceae, Cucumis) cultivation, focusing on premium melon production by PT. Indominco Mandiri within its Community Development and Empowerment program. A hydroponic system, which involves the cultivation of plants in a soilless medium with a nutrient solution, was employed due to its advantages in improving plant quality and yield. Findings demonstrate that melon thrives in ex-mining conditions, reaching harvesting maturity within 2.5 months, with fruits noted for their sweetness. Additionally, melons were found to be a rich source of vitamins A, K, C, B-6, E, niacin, and essential minerals including calcium, potassium, ferum, magnesium, phosphorus, sodium, and zinc, with low sodium and no fat content. This research underscores the hydroponic system’s potential in reclaiming post-mining lands, enhancing economic viability and fostering community development and empowerment. The implications of these findings extend to environmental rehabilitation and sustainable agriculture practices, offering a feasible and productive use of post-mining land globally.
