Abstract

Traditional petroleum mining is mining that produces liquid and solid waste which can cause environmental pollution. This research aims to determine the impact of traditional petroleum mining waste on surface water quality and calculate the level of surface water pollution. Research was carried out in November, using survey methods and purposive methods to determine the location and collection points for waste water and surface air. Petroleum wastewater and surface water samples have been taken using the grab sampling method. The wastewater samples consisted of 6 samples in the form of 3 samples (B1, B2, B3) from oil wells that were operationally active 24 hours / day. 3 samples (C1, C2, C3) from operational passive oil wells 3 times for 4 hours/day. Surface water samples were taken at 6 points, namely A0 as control, 0km (A1), 0.5km (A2), 1km (A3), 1.5km (A4), 2km (A5). The parameters that have been tested include temperature, TDS, TSS, pH, BOD, COD, DO, fatty oil, ammonia, H2S and phenol. The quality of waste and surface water has been determined based on Minister of Environment Regulation No. 19 of 2010 and Government Regulation Number 22 of 2021. The level of water pollution has been determined using the Pollution Index (IP) method. The results of the research that has been carried out show that TDS, COD, fatty oil, NH3 from active well waste (B) and COD, fatty oil from passive well waste (C) exceed quality standards. Surface water quality has TDS, BOD, COD, fatty oils, NH3, and phenols exceeding class III water quality standards. The level of surface water pollution includes Light Pollution to Moderate Pollution. The farther the sample point is from outlet waste, pollution levels have decreased.

Abstract

Coal mining activities can cause significant ecosystem changes. This needs to be remedied by reclamation. In reality, reclamation carried out in the field is not always successful, hence the need for monitoring This study integrates remote sensing technology in the form of aerial photo analysis and spatial mapping using the ArcGIS application, combined with biophysical assessments in the field. The purpose of this study is to quantitatively assess the success rate of post-mining land reclamation in the area of ​​the Air Laya Mining IUP of PT. Bukit Asam Tbk and to identify factors that support or hinder the reclamation process. This study uses the Minister of Forestry Regulation No. P.60 of 2009 with parameters of land management, erosion and sedimentation control, and revegetation. Data was collected using reference study, survey, sampling, scoring and analysis. The revegetation plants used are revegetation with the age of 1 years, 2 years and 5 year. Revegetation assessment was conducted by purposive sampling, based on planting year and ease of access using sample plots. The number of sample plots was determined as 5% of the total reclamation area. The number of sample plots observed was 6 plots with a size of 40 x 25 m. The results showed that reclaimed land with revegetation aged 5 and 2 years fell into the good and successful category with evaluation scores of 81 and 85. Whereas on reclaimed land with 1 year old revegetation is included in the medium category and is acceptable but must be improved again with an evaluation value of 75.5. Inhibiting factors for the reclamation process include poor integration of drainage channels, very acidic soil pH, and lack of local plants.

Abstract

Post-gold mining soils are generally characterized by acidic pH, low organic carbon (C-organic) content, and poor macronutrient levels, particularly nitrogen (N), phosphorus (P), and potassium (K). This study aimed to evaluate the effect of applying organic fertilizer derived from maggot livestock waste and natural phosphate rock on soil pH, C-organic, and N, P, and K content in post-gold mining land. The research employed a factorial completely randomized design (CRD). The first factor was maggot-based organic fertilizer applied at three rates: 0 g/pot, 8.3 g/pot, and 16.6 g/pot. The second factor was natural phosphate rock, also at three rates: 0 g/pot, 0.16 g/pot, and 0.33 g/pot. This resulted in 9 treatment combinations, each replicated 3 times, for a total of 27 experimental units. Soil parameters analyzed included pH, C-organic, total N, available P, and available K. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at the 5% significance level where applicable. The results indicated that maggot fertilizer significantly increased the availability of P and K, while natural phosphate rock significantly increased available P. A significant interaction between maggot fertilizer and phosphate rock was observed for soil pH. The optimal combination for improving pH was the application of 20 tons/ha of maggot fertilizer (equivalent to 16.6 g/pot) and 400 kg/ha of natural phosphate rock (equivalent to 0.33 g/pot).

Abstract

Land degradation in upland sub-watersheds poses serious threats to environmental sustainability, agricultural productivity, and disaster risk. This study aims to evaluate the land condition of the Sileng Sub-Watershed in Borobudur District, Central Java, using an integrated approach based on four key indicators: erosion index, land cover index, land use suitability, and landslide susceptibility. Field surveys and spatial analyses were conducted in 18 land system units, with supporting data derived from Sentinel-2 imagery and regional spatial planning maps. The results show that 61.1% of land systems are in good condition, 33.3% in fairly good condition, and 5.6% in moderate condition. While erosion risk is generally low, two land systems show critical erosion and landslide susceptibility due to steep slopes and minimal vegetative cover. The high land use suitability (88.36%) indicates strong adherence to spatial planning regulations, while the land cover index (63.71%) suggests moderate vegetation density. Overall, the integrated land condition index highlights both areas of ecological resilience and zones requiring rehabilitation. These findings offer valuable insights for sustainable watershed management and policy formulation, particularly in tropical highland areas vulnerable to land degradation and climate impacts.

Abstract

PT Internasional Prima Coal is a coal mining company utilizing open-pit mining methods, which has the potential to generate acid mine water that can be environmentally damaging if discharged directly into rivers. Hence, the necessity for management, one of which includes the use of settling ponds. The research aims to understand the application of the settling pond system in acid water management and determine the quality of acid mine water and sediment from the inlet to the outlet zones of settling ponds 01 and 08. The research employed survey and laboratory analysis methods. Sampling of acid mine water utilizes grab sampling techniques, while sediment sampling utilizes a core sampler. Parameters used for acid mine water and sediment samples included pH of water, sediment pH (H2O, KCl), Eh, TSS, Fe, Mn, Pb, and Cd levels. Determination of acid mine water quality referred to the East Kalimantan Regional Regulation No. 2 of 2011 concerning the Quality Standards of Coal Industry Wastewater, specifically for pH, TSS, Fe, and Mn, and Minister of State for the Environment Decision No. KEP-51/MENLH/10/1995 for Pb and Cd. Sediment quality referenced the Guidelines for the Protection and Management of Aquatic Sediment Quality in Ontario. The research results indicate that acid mine water and sediment generated by mining activities exhibit characteristics of Fe, Mn, Pb, Cd, and TSS meeting the quality standards but possess low pH values (acidic), especially in Settling Pond 01. Acid mine water that underwent treatment experienced an increase in quality, making it safe for discharge into water bodies. The water flow rate requiring treatment in Settling Pond 01 is 1.110 m3/s sourced from rainwater, runoff, while Settling Pond 08 is 0.704 m3/s from rainwater, runoff, and pumping from the mine's sump pit.
