Acid mine drainage has been reported to cause various environmental and human health problems. Acid mine drainage is formed due to the oxidation of sulfide minerals to water and air. This paper reports the efforts that have been made in the management and treatment of acid mine drainage. Thirty papers from reputable publishers are used as references. Efforts to prevent the formation of acid mine drainage can be made by making proper drainage and dewatering systems, making non-acid formations for rocks that have the potential to be oxidized. Active and passive treatment methods can be used to treat acid mine drainage. The active treatment method uses materials and chemicals to reduce pollutant parameters, while the passive method utilizes natural processes to reduce pollutant parameters in acid mine drainage. The combination of active and passive methods using novel materials that have been researched is recommended to produce the best system that can thoroughly remove pollutants in acid mine drainage.

Environmental conservation determines the life of humans and other living things, but on the other hand, humans can also select the state of their environment. With the lack of public knowledge about preserving the environment, people unwittingly pollute the environment by littering on empty land that is not used. There is a buildup of waste that pollutes the air, water, and soil. The Pematang Lingkung Village Government takes steps through the BUMDes Program to prevent environmental pollution by utilizing vacant land that is not used as a tourist spot in the form of the Melik Sisik Park as an effort to preserve the environment. This study aimed to determine the condition of BUMDes and the role of BUMDes in environmental conservation. This type of research uses a quantitative approach with 80 respondents. Sampling technique with a questionnaire instrument was employed. Descriptive data analysis and Chi-Square test was conducted to analyze the results. A qualitative approach is used to understand the development and dynamics of BUMDes in the context of rural economic development, especially in rural community business processes. The industry's environmental management and monitoring implementation had not raised awareness of environmental conservation; community involvement and concern in ecological management and monitoring are still low. The results showed a relationship between the role of BUMDes and environmental conservation in Pematang Lingkung Village.

Garang River is administratively located in Semarang Regency, Kendal Regency, and Semarang City. Population growth and the number of community activities around the river can affect the water quality of the Garang River. Wastewater discharged into the Garang River will reduce water quality. The number of pollutants that enter the river changes the quality of river water until it reaches a pollutant level that exceeds the quality standard. The purpose of this study was to determine the self-purification ability of the Garang River using the Streeter-Phelps method based on DO and BOD parameters to obtain an oxygen sag curve for oxygen reduction. There are 3 monitoring stations that are located in the upstream segment of the Garang River. The value of the deoxygenation constant (K) in segment 1 is around 0.340, the reaeration constant (R) is 3.433, and the value of fs = 10.103. While in segment 2. the value of K is 0.335, R is 3.417, and fs is 10.194. It is revealed that segment 1 and segment 2 of the Garang River have not yet experienced optimal natural purification because they are still in the degradation zone.

The Indonesian government has implemented clinical sanitation to improve a healthier environment and reduce mortality from environmental-based diseases. This effort is carried out to reduce the incidence of environmental-based diseases such as diarrhea and Acute Respiratory Infections (ARI). However, in 2017 the number of ARI sufferers in one of the provinces in Indonesia reached 45.38%, while diarrhea reached 28.3%. The diarrhea mortality rate increased to 4.76% in 2018, while the prevalence of ARI reached 9.1%. Therefore, this article aims to examine the performance of the sanitation clinic program at the Indonesian Health Center. The review method used is the narrative. Total percentage of 78.33% for the category of public health centers that have carried out the stages of sanitation clinics starting from the counselling stage to the intervention stage following established regulations. This percentage is still low because it has not received a 100% score. The implementation of the program has not been supported by adequate counselling media. In addition, the Public Health Center does not yet have a counselling room, and there is still a shortage of operational funds. Monitoring and evaluation need to be carried out to improve the service performance of the sanitation clinic program.

Amplapura is located in the highlands having a potential area of green open land which can absorb rainwater freely into the ground. However, in recent times, land conversion has begun to develop with new housing buildings, Griya Galiran Regency Housing. Furthermore, the effectiveness of the land area is still able to absorb water and maintain groundwater balance. A rainwater harvesting plan (RH) is needed, or, more popularly, rainwater harvesting. In this area. The aim is to provide a portion of residential land space for rainwater infiltration into the pores or soil cavities using the infiltration well method. The results showed that the Griya Galiran Regency Housing had an acceptable sand soil type and absorbed soil quickly, with a soil permeability coefficient (k) of 0.0014 cm/s. Designing the dimensions of the infiltration well at the Griya Galiran Regency Housing with an area of 70 m2 based on SNI 03-2453-2002 for a circular cross-section, an infiltration well with a diameter of 1.2 m with a depth of 2 m is made. In contrast, as a rectangular cross-section, an infiltration well has a side length of 1 m with a depth of 2 m.

An increasing number of laundries have caused water contamination by surfactants. One commonly used surfactant is LAS (Linear Alkylbenzene Sulfonate), a material difficult to decompose, polluting the environment. Electrocoagulation was carried out using Al/Graphite electrode, applied to LAS surfactant artistic waste. This study aims to determine the functional ability of the Al/Graphite electrode in reducing surfactant through electrocoagulation. Various variations were carried out, on the voltage parameters (3,6,9,12) Volt; NaCl concentration (0;0.4;0.8;1.2;1.6;2) g/L; pH (3,5,7,9,11) and time (10,20,30,40,50) minutes. To analyze the changes in the sample before and after electrocoagulation, characterization was carried out using a UV-VIS spectrophotometer and FTIR. A kinetic study was conducted to determine the reaction order of electrocoagulation surfactant. Based on a study, removal at condition voltage 9 Volt, initial pH of the solution 9, electrocoagulation time 50 minute, and the addition of NaCl electrolyte 2 g/L, obtained surfactant concentration was 0,785 mg/L with removal efficiency 97,45%. UV-VIS spectra show a decreased absorption at a wavelength of 653 nm. FTIR spectra showed the presence of absorption on the same functional groups, which indicated that most of the surfactant pollutants could be separated from the wastewater through the electrocoagulation process. The second-order reaction was obtained in the surfactant electrocoagulation process.

The Jatiluhur Reservoir is an important building in West Java Province whose dams the Citarum River. The location of the Jatiluhur Reservoir, which is the most downstream of the Saguling and Cirata Reservoirs, is where domestic, industrial, and agricultural wastewater pollution is accommodated from water catchment areas so that water quality decreases. This study aims to analyze the water quality in this reservoir at various depths. The study was conducted in September 2020 at 16 sampling points at a depth of 0-8 meters. The water quality parameters analyzed were Temperature, Dissolved Residue (TDS), pH, Dissolved Oxygen (DO), Fluoride (F-), Nitrate (NO3-N), Sulfate (SO42-), BOD5, COD, and Escherichia coli. Based on the study results, it was found that the concentrations of DO, BOD5 and COD at the monitoring location of the Jatiluhur Reservoir did not meet the quality standards. The concentrations of DO, BOD5 and COD respectively 1.00-3.99 mg/L; 3.10-17.00 mg/L; and 28.00-59.00 mg/L. These three parameters contribute to the decline in water quality. The status of water quality using the IP method is categorized as lightly polluted so that it affects the utilization of this reservoir, especially as raw water for drinking water. The highest level of contamination was at the floating net cages sampling location at a depth of 8 m. The decline in water quality in the Jatiluhur Reservoir is caused by organic substances originating from floating net cages waste.
