Abstract. Coal prices between 2006-2015 trend was fluctuate but tend to decrease every year and affect regional income, especially South Sumatra Province. Coal prices fluctuation are influenced by several factors, the decline of world oil prices, coal production surplus, and China imports restriction. Coal mining industry also give a direct impact to the environment especially effect to work environment for the company workers and the people environment around mining. The coal mining company absorbs local labor so as to increase local revenues from individual income taxes. This research use quantitative approach using Ordinary Least Square (OLS) analytical method with E-views 7 software. Multiple linier regression technique also applied. The Secondary data is time series of 2006 - 2015. The results presented in form of tables, images and narration. From this research can be drawn conclusion that price fluctuations have no effect on regional income, but production sold has an effect on regional income. Keywords: Sale, price, royalty, Personal Income Tax Article 21, and Personal Income Tax Article 25/29 Abstrak (Indonesian)Harga batubara kurun 2006-2015 mengalami fluktuasi sehingga berpengaruh terhadap pendapatan Provinsi Sumatera Selatan. Fluktuasi harga batubara dipengaruhi oleh beberapa hal yaitu menurunnya harga minyak dunia, adanya kelebihan produksi batubara, dan pembatasan impor batubara oleh Cina. Industri pertambangan batubara memberikan dampak terhadap lingkungan salah satunya tenaga kerja. Perusahaan pertambangan batubara menyerap tenaga kerja lokal sehingga meningkatkan pendapatan daerah dari pajak penghasilan perorangan.

The construction of power plants is very necessary to anticipate the crisis of electricity resources and always increases every year. Tanjung Enim city has Steam Power Plant (SPP), one of them is Banko SPP which has 3 x 10 MW capacity. It was built to meet the demand for society electrical energy. The existence of this SPP construction can cause environmental degradation such as a decrease in water quality that does not meet environmental quality standards. The decline in environmental quality can also have a direct impact on the community around the Tanjung Enim SPP location. This is due to the existence of SPP operational activities that can produce liquid waste such as boiler blowdown, airheater blowdown, cooling system and domestic waste waterfrom the manufacturing process. This research study aims to analyze water quality around Banko SPP based on the physical and chemical parameters by testing in the laboratory. The approach employed in this study was an experimental method that included laboratory sample and testing. The water quality pollution index (PI) which refers to the Ministerial Decree No. 115/2003 (Environmental Decree) was used to analyze the result of laboratory testing. The water quality samples examined in this study were wastewater treatment plant (WWTP) outlet, river water, and groundwater nearest to the SPP's location. The phenol and chlorine parameters exceeded the quality requirements referred to in the South Sumatra Governor Regulation No. 16 of 2005, according to the findings of laboratory testing of river water samples. The mercury (Hg) parameter in the WWTP outlet samples surpassed the South Sumatra Governor Regulation No. 16 of 2005 quality criteria. Meanwhile, the manganese (Mn) parameter in groundwater samples surpasses the quality requirement established by the Government of South Sumatra Regulation No. 82/ 2001 as Class I clean water quality criteria. The water quality pollution index (PI) method achieves a score of 1.52 with the category of Lightly Polluted. Based on these findings, it can be concluded that the influence of SPP Banko's operations on water contamination is minor.

Mining of rocks, particularly andesite, in East OKU Regency provides significant economic contributions but generates environmental impacts that require rehabilitation through reclamation and post-mining management. This study aims to evaluate the compliance level of Production Operation Mining Business License (IUP OP) holders with these obligations and to identify challenges in their implementation. A descriptive quantitative and qualitative approach was employed, with primary data collected through interviews and field observations related to reclamation and post-mining plans, as well as the placement of guarantees. Secondary data included IUP licensing documents, legislation, and guidance letters from the Energy and Mineral Resources Office of South Sumatra Province. Quantitative analysis categorized compliance levels, while qualitative analysis examined challenges and guidance strategies. The results indicate variations in IUP OP holders’ compliance; some have prepared documentation and placed guarantees, but delays and lack of continuity were observed. Major challenges include profit-oriented approaches, limited technical and environmental understanding, and limited permit duration. Guidance strategies, supervision, guarantee management, provision of technical experts, and community empowerment proved essential. These findings have implications for enhancing compliance, sustainable post-mining planning, and responsible mining practices.

This study aims to evaluate the feasibility of using blended coal as fuel for steam power plants (PLTU) by examining the quality of MT-47 coal from PT Bukit Asam through proximate analysis and statistical trend analysis. High-calorie coal (A) and low-calorie coal (B) were blended at ratios of 30:70, 40:60, 50:50, and 60:40, and then tested in the laboratory to determine the intrinsic moisture (IM), ash content, volatile matter (VM), and fixed carbon (FC) content. The test results showed that the IM value ranged from 24.78–27.93%, ash from 4.52–5.79%, VM from 36.05–39.21%, and FC from 30.22–31.50% (adb). Regarding the quality of MT-47, only the ash parameters at the 30:70 and 40:60 ratios meet the standard limits, while the IM, VM, and FC at all ratios do not comply with the MT-47 specifications. Linear regression analysis and Pearson correlation coefficients show a very strong linear relationship between the blending ratio and all proximate parameters, with high correlation values (|r| > 0.95) and coefficients of determination above 95%, thus indicating a consistent trend of quality changes due to variations in the blending ratio. Overall, the 30:70 ratio is the composition closest to the quality of MT-47, although this coal mixture still requires further quality improvement processes to be suitable for direct use as PLTU fuel.
