摘要

PT. PQ进行的煤炭开采活动引起环境环境的变化,因此需要根据其指定恢复其功能。土地功能的恢复是通过填海活动来实现的。需要对填海活动进行评价,以便继续作出改进和取得最佳结果。本研究评估了利用PT. PQ进行填海的成功率。本研究旨在审查和评估PT进行的填海活动。PQ基于2018年能源和矿产资源部第1827/30 K/MEM号法令。研究方法为野外观测;土地利用、植被恢复和维护阶段的一手、一手数据分析;并对回收成功率进行了数学计算。通过测定H2O、有机C、全n的pH值来检测土壤质量。结果表明,垦区土壤为酸性,即H2O pH值为4.5 ~ 5.5;有机碳减少1-2%;N总量为0.1 - 0.2%;C/N为5 - 1试验,对pH H2O、有机C、N的总回收成功率为94.1或在良好范畴。垦区土壤pH值为4.3,土壤有机碳含量小于1%。主要的桉树油料植物需要pH值为4.5 -5.5的土壤。有机碳减少1-2%;N总量为0.1 - 0.2%;C/N (5 - 1)为了完成复垦活动,需要提高土壤的pH值,土壤的pH值仍然是酸性的,即4.3,增加土壤的有机碳含量,土壤的有机碳含量仍然很低,即<1%。酸性土壤pH值和土壤有机碳含量低于主要植物桉树油所需的标准,是改善PT. PQ垦区土壤条件的初步信息,使垦区活动更好地进行。

Evaluasi Reklamasi di Area Pertambangan Batubara PT. PQ, Kecamatan Tanjung Kidul, Kabupaten Muara Enim, Provinsi Sumatera Selatan
Coal mining activities carried out by PT. PQ causes a change in the environmental setting so that its function needs to be restored according to its designation. The return of land function is carried out through reclamation activities. Reclamation activities need to be evaluated in order to continue to make improvements and optimal results. This study assesses the success rate of reclamation carried out by PT. PQ. This study aims to examine and evaluate the reclamation activities carried out by PT. PQ is based on Decree of the Minister of Energy and Mineral Resources Number 1827/30 K/MEM of 2018. The research method used is field observation; analysis of primary and secondary data on land use, revegetation, and maintenance stages; and mathematical calculation of reclamation success rate. Soil quality was tested by testing the pH of H2O, organic C, and total N. The results showed that the soil in the reclamation area is considered to be acidic, namely the pH of H2O is 4.5 -5.5; organic C by 1-2%; N total of 0.1 – 0.2%; C/N of 5 – 1 test for pH H2O, organic C, and N total reclamation success rate of 94.1 or in the good category. The soil in the reclamation area has a pH of 4.3 and a soil organic C content of less than 1%. The main eucalyptus oil plants require soil with a pH of 4.5 -5.5. organic C by 1-2%; N total of 0.1 – 0.2%; C/N of 5 – 1. To complete the reclamation activities, it is necessary to increase the pH of the soil, which is still acidic, namely 4.3 and to increase the organic C content of the soil, which is still low, namely <1%. Findings of acidic soil pH and soil organic C content below the standard needed for the main plant eucalyptus oil are initial information for improving soil conditions in the reclamation area of PT. PQ so that reclamation activities run better.
