Abstract

This research was aimed to investigate effect of oil spills on surface water from exploration in Dutch well.The investigation was carried out by in situ measurement of some parameters.Water sample was collected by grab sampling method and the analysis was conducted at Laboratory of Environment Badan Lingkungan Hidup dan Penelitian Pengembangan (BLHPP) Kabupaten Musi Banyuasin.The measurement result showed that some parameters did not fulfill the requirement of Standar Quality for Domestic Water Regulation according to Government Regulation No. 82 year 2001 i.e. COD and Oil&Fat content. The surface water and shallow ground water quality had some parameters that did not comply with standar quality according to regulation such as BOD, COD, DO, and oil-fat content.Calculation of pollution indeks (PI) showed that domestic water has 3.26 and was categorized into slightly polluted. At surface water in Angit River, the calculation of PI showed that upstream river was slightly polluted (3.23), while midstream was slightly polluted (3.22) and in downstream river was mildly polluted (9.60).

Abstract

Land use-land cover (LULC) is one of the indicators commonly used in monitoring the quality of natural resources. Most of the Ogan watershed is a peat ecosystem that plays an important role in maintaining the balance of the ecosystem and water supply. During the 2014-2019 period the Ogan watershed experienced several wildfires and infrastructure development, particularly freeways. This study aims to analyze changes in the LULC in the Ogan watershed during the 2014-2019 period. LULC analysis uses remote sensing technology by utilizing Sentinel and Landsat satellite imagery data. LULC identification used the visual image interpretation method, while LULC changes were analyzed using the GIS technique with the spatial overlay method. The results showed that changes in LULC led to the LULC managed class, where the increase in area occurred in the rubber and oil palm plantation classes. Meanwhile, the highest reduction in area occurred in the dry land forest class. Changes in LULC that occurred during the observation period had a negative impact on the watershed in the form of land degradation, decreased levels of biodiversity and increased fire vulnerability. Based on these results, land use in the Ogan watershed needs to be controlled and land management practices must pay attention to environmental sustainability aspects.

Abstract

The Oal River receives coal wastewater input at several companies. Coal mining in the vicinity of the location adds to the burden of water pollution in the Oal River due to waste water disposal activities. The increase in the concentration of coal waste and the pollution load that enters the Oal River water body will have an impact on the reducing capacity of the pollution load. This study aim to provide information on the condition of the pollution load carrying capacity of the Oal River. Determination of the carrying capacity of water pollution loads at water sources using the mass balance method. The characteristic of the Oal River water with the parameters TSS, pH, Fe and Mn have not yet passed the quality standards for river water and wastewater, both according to PP No. 22 of 2021 and South Sumatra Governor Regulation No. 8 of 2012. The Oal River still has the capacity to accommodate TSS and pH parameters.

Abstract

The present study focuses on the assessment of Hg distribution in both soil and water samples from the small-scale gold mining region of Karang Jaya Sub-district, Musi Rawas Utara Regency, South Sumatra Province. For over 30 years, this region has witnessed persistent utilization of mercury as an amalgam for gold extraction. The investigation encompasses an analysis of total mercury levels in soil samples obtained from Sukamenang, Muara Batang Empu, and Terusan Villages. As a comparative reference point devoid of gold mining activities, the neighboring Muara Lakitan Village was selected. The obtained results indicate a moderate to strong contamination level across the 30 sampled locations based on the Geoaccumulation Index (Igeo), with an average Igeo value of 2.6. Furthermore, Pollution Load Index (PLI) and Contamination Factor (CF) values demonstrate high contamination. Conversely, analysis of river water samples from 30 stations along the Rupit River reveals that most of the samples comply with quality standards (<0.0005 mg/L), with an average value at 0.000322 mg/L; only four stations exhibit total Hg concentrations surpassing regulatory thresholds. All soil and river water samples from the control area (10 stations) exhibited no signs of pollution. Appropriate investments in technology, finance, and technical skills are needed to reduce mercury pollution due to small-scale gold mining activities.

Abstract

Enim river flows within several sub-districts in Muara Enim Regency, including Semendo Darat Laut, Semendo Darat Tengah, Semendo Darat Ulu, Tanjung Agung, Lawang Kidul, and Muara Enim. This study examines changes in the water quality of the Enim River due to domestic wastewater discharges and the presence of the coal mining industry and household industries. Water samples were taken from 4 sampling stations along the Enim River in 2018 and 2023. Data consisted of results of physical, chemical, and microbiological parameters. The status of river water quality was assessed from the pollution index. The results of Enim River surface water quality measurements showed that the parameters of total suspended solids, Dissolved Oxygen, iron (Fe), copper (Cu), oil, and grease concentrations had breached the criteria set for Class II water quality, referring to Government Regulation of the Republic of Indonesia Number 82 of 2001. The results showed that there has been a change in the water quality status of Enim River from 2018 to 2023. The river water pollution index was (1.43-2.47) in 2018 and (1.49-3.85) in 2023 (lightly polluted). Comprehensive water treatment and preventive measures are necessary to manage and mitigate additional pollution in the Enim River.

Abstract

The environment consists of land, the earth's atmosphere, and air. Air quality is a measure of air conditions relative to the needs of one or more biotic species. The results of the air quality analysis obtained cloudy water at sampling points 1-5, parameters below class II water quality standards are found in pH parameter at points 6-15, DO parameter at all points, BOD parameter at all points, COD parameter at points 4-6, TSS parameters at points 1-5 and 7, while the temperature and TDS parameter are still below the quality standards at all sampling points. The results of heavy metal measurements obtained Pb parameter at all points, Cu parameter at points 4-15, Cd parameter at point 7, Fe parameter at all points, Mn parameter at points 1-3 and 6-15, while the Cr parameter is still below the quality standards at all sampling points. Point 8 obtained an index value of 5.13, which means moderate pollution, while points 1 to 7 and points 9 to 15 were lightly polluted.

Abstract

The availability of clean water is an essential element for supporting the life cycle and sustainable development. The efficiency of providing raw water sources is an important factor for adequate water quantity and quality. This study examines the effectiveness of alum compared with coal-based activated carbon in the removal of Fe, Mn, and turbidity in raw water from the Lematang River, Muara Enim Regency. Activated carbon in this study was produced using a KOH activator with varying activation temperatures (700 °C, 800 °C, and 900 °C). The research results showed that the quality of the third activated carbon met the active carbon quality standards (moisture, ash content, Methylene blue dye and iodine adsorption capacity), but the activated carbon with activation at a temperature of 800 °C had the largest surface area. Activated carbon was proven more effective in reducing Fe and Mn concentrations than alum, while alum was superior in reducing turbidity. After three cycles of activated carbon regeneration, the reduction in Fe and Mn remained below 5%. These results show that activated carbon is a cost-effective and eco-friendly option for raw water treatment.Keywords: Coal, activated carbon, alum, raw water, regeneration
