How is the Alternative Use of Post Mining Land? Empirical Evidence at PT. Nuansacipta Coal Investment
Keywords:
Reclamation, Land Use, Regulation, Coal Company, Sustainable environmentAbstract
Mining is carried out in an open system so that technically there is a possibility that there will be remnants of ex-mining holes that cannot be backfilled. This qualitative research uses a case approach to the selected Nuansacipta Coal Investment (NCI) company on the basis that the company has carried out reclamation and has prepared Postmining Plan Documents. The results of the research found alternative post-mining land use through 1) Land use for plantations; only the pH parameter, which was not met, because the pH value was < 5 while other parameters such as clay content, CEC value, base saturation, Carbon, Al, Fe, spirit, Ca AndMg all fulfilled for good soil conditions as Plantation. Soil quality in the Lychee ex-pit can be met with the addition of lime so that the plant conditions revegetation looks well grown; 2) Aquaculture; visible only parameter Manganese (M N) that do not meet the Environmental Quality Standards based on East Kalimantan Regional Regulation number 02 of 2011 concerning Water Quality Management and Water Pollution Control. Through the use of ponds for fish farming, it can be done with a little management to neutralize the manganese content so that it meets environmental quality standards, and 3) Land use (coal hauling road) as a community access road: it has been tested by the company by using trucks (tipper truck) has a capacity of more than 20 tons round trip, so the road is quite stable. Efforts to use post-mining land at PT. NCI is carried out based on the Postmining Plan Document, so as not to have a major negative impact on the economic, social, and ecological sectors. Therefore, the post-mining land reclamation program NCI is important to do in order to make the land return to its original state and increase land productivity. The implementation of the reclamation of PT. NCI can be carried out in the form of afforestation, agriculture, forestry, renewable energy development, tourism, and urban or industrial development.References
