Khatulistiwa Makmur Persada is a company engaged in the coal mining industry. Meanwhile at PT. Khatulistiwa Makmur Persada, there are indications of a decrease in coal quality when coal is mined, this is due to a pool of water around the coal to be mined. This research was conducted using quantitative research methods. Quantitative research methods. By conducting tests on coal samples and interviewing workers for questionnaires. The results of the analysis of coal quality show changes when coal is transported to the stockpile from the mining front with a change in quality of 2.78% total moisture, 15.65 ash content, 1305.01 Kcal/kg calorific value. And the results of the analysis of changes in the quality of coal in the stockpile with the range determined by the company with a total moisture value of 1.36%, ash content of 7.46%, calorific value of 708.03 Kcal/kg. PT. Khatulistiwa Makmur Persada merupakan perusahaan yang bergerak di bidang industri pertambangan batubara. Sementara itu di PT. Khatulistiwa Makmur Persada, terdapat indikasi terjadinya penurunan kualitas batubara pada saat batubara ditambang, hal ini disebabkan adanya genangan air di sekitar batubara yang akan ditambang. Penelitian ini dilakukan dengan menggunakan metode penelitian kuantitatif. Metode penelitian kuantitatif. Dengan melakukan pengujian terhadap sampel batubara dan wawancara pekerja untuk kuisioner. Hasil analisis kualitas batubara menunjukkan perubahan pada saat batubara diangkut ke stockpile dari front penambangan dengan perubahan kualitas 2,78% total moisture, 15,65 ash content, 1305,01 Kcal/kg calorific value. Dan hasil analisis perubahan kualitas batubara di stockpile dengan range yang telah ditetapkan perusahaan dengan nilai total moisture 1,36%, ash content 7,46%, nilai kalori 708,03 Kcal/kg.

“…This process was used to provide a potable water resource assessment. Previous studies stated the provisions of bene ts and costs directly ( nancially) and indirectly (externalities) in economic, social, and environmental aspects, by the open coal mining [5,27,44,45,[57][58][59][60][61][62]. Economic valuation in this study was performed on erosion, domestic water, and raw water values of TAL PTBA, using extended bene t and cost analysis model.…”

Effective water resource management offers a very significant value across social, economic, commercial and environmental application. For this fundamental reason, adequate sustainability becomes equally crucial. Therefore, activities geared towards the depletion in quantity, quality, and loss of potable water resources, particularly for communities, demand urgent reconsiderations. Erosion in coal mining land causes depletion in water quantity and quality, as well as inadequate drinking water resources for surrounding communities, making water resources unsustainable. Meanwhile, reclamation reduces erosion, but is unable to restore water depletion optimally, thus, these resources remain unsustainable. these resources remain unsustainable. However, recycling depleted water utilization for drinking provides economic value for the environment, as well as the community’s drinking water resources’ availability and sustainability. The objectives of this study were to develop water resource sustainability concept for a sustainable environment by analyzing the potential economic value and secondly, calculate the water resource value due to erosion, reclamation, domestic and economic importance, by recycling efforts. The method used in this study was the Extended NPV. Furthermore, the total potential economic value of water resources loss resulting in water resource unsustainability was IDR 1,137,621,671,375 or IDR 1.14 trillion, while the potential economic value of depleted water utilization for drinking was IDR 2,298,339,797,000 or IDR 2.3 trillion. Therefore, this utilization provides potential economic value worth IDR 1.16 trillion, for the resources’ sustainability in the TAL area of PTBA. The study’s results found and recommended depleted water utilization for drinking as a suitable method to replace water resources lost due to erosion, community drinking water resource loss, and to discover a sustainable environment’s water resources sustainability concept. In addition, the study formulates environmental economics as a new mining science related to natural resource economics as well as mining, for sustainable water resources and mining environment.
