Abstract

ABSTRACTThe mining and processing of people's gold produces impacts on the surrounding environment. Some residents immediately dumped the waste gold processing results into the environment. It is necessary to analyze the actual condition of mercury pollution based on a map of the level of pollution vulnerability to determine the size of the level of difficulty and the ease of polluted substances to affect surface water quality. The purpose of this study is to analyze the actual condition of the level of vulnerability of surface water pollution around the study area. The method used in this study is a survey method and field mapping, sampling methods: purposive sampling, laboratory analysis methods, mathematical methods, and descriptive evaluation methods. Calculation of the level of vulnerability of surface water is the PCSM (Point Count System Model) method with 3 parameters, namely land use, slope, and rainfall. Overlay is done between the level of pollution vulnerability map with the actual conditions of pollution in the field. The results showed the study area has a level of vulnerability to surface water pollution in the study area including the classification of quite vulnerable and very vulnerable. Based on the results of the study it can be concluded that the total score of 36-43 included in the vulnerability class is quite vulnerable. The total score of 43 - 50 is included in the very vulnerable vulnerability class. Actual mercury levels in the study area were known in a row AP1-AP6 samples were 0,00046 mg / L; <0.00006 mg / L; <0.00006 mg / L; <0.00006 mg / L; 0,00039 mg / L and <0,00006 mg / L. These results indicate that surface water in the study area has not been contaminated with mercury because its value is brought to all quality standards.

Abstract

Study Of Leachate Quality to Groundwater Quality Around Jetis Landfill, Pakem, Gebang District, Purworejo Regency, Central Java Province (Ika Wahyuning Widiarti and Eni Muryani): Organic waste will be decomposed easily and produce leachate. Leachate may pollute soil, groundwater and river around TPA (Final Disposal) Jetis if it does not manage well. The objectives of this research are to describe leachate quality with parameters pH, BOD, COD, TSS, N-Total, Hg and Cd, to analyse the status of groundwater quality, and to evaluate the connection between leachate quality and groundwater quality around TPA Jetis. Leachate sampling was conducted at inlet and outlet of WWTP of TPA Jetis and the groundwater sampling was conducted at resident well and monitoring well. Research result showed that parameters BOD, COD, and TSS at inlet exceeded the standard. While the all parameters of the outlet were still meet the standard. The status of groundwater quality included lightly polluted with PI for monitoring well was 1.082 and for resident well was 2.912. Laboratory results showed that the resident well has BOD and COD values that exceed the standard. So that it can be expected that groundwater contamination occurs because of leachate from the TPA Jetis so that the groundwater quality of the resident well around the landfill decreases.

Abstract

The northeastern slope of Mount Arjuno, Pasuruan district, East Java province, Indonesia represents a vast and good groundwater resource quality, generally be exploited by some companies for drinking water industries. Water unbalance and quality degradation is presumed to arise because groundwater extraction volume is getting bigger but less control by the regency authority. This study is to figure out the geologic condition and hydrogeological system, conduct groundwater exploitation risk assessment, and develop a conservation program. The study results show that the study area's geomorphological units can be divided into the volcanic summit, volcanic slope, fluvial plain, and anticlinal hills. The lithology comprises sandstone, breccia, and andesite lava of Mount Arjuno and Mount Welirang. The geological structures are anticline, normal fault, and lateral slip fault. Hydrologically, there are three watersheds, including Lumbangrejo, Ketanireng, and Prigen watersheds. The aquifers comprise unconfined to semi-confined aquifers with fissures and intergranular porosity. Based on risk assessment valuation, Pecalukan village of the Ketanireng watershed and Lumbangrejo village of the Lumbangrejo watershed are categorized as very high groundwater vulnerability zones, Karangrejo and Sukoreno villages of the Lumbangrejo watershed, Kedungringin, Kepulungan, and Gunungsari villages of the Ketanireng watershed are categorized as medium vulnerability zone. While, Ngorong village of the Lumbangrejo watershed, Gempeng, Oro-Ombo, Kalisat, and Dukuhsari villages of the Prigen watershed belong to the low vulnerability zone. The proposed conservation programs involve profitable water use safety campaigns, domestic waste, and industrial wastewater management, agricultural activities controlling, sandstone mining regulation, and reforestation.

Abstract

The people's gold mining and processing activities have an impact on the surrounding environment. Some residents immediately dispose of waste from gold processing into the environment. Therefore, analysis of the level of vulnerability of pollution is needed to determine the size of the level of difficulty and ease of contaminated substances to influence water quality, both surface water and groundwater. The purpose of this study was to analyze the level of vulnerability of groundwater pollution around the study area. The method used in this research is survey method and field mapping, sampling method: purposive sampling, laboratory analysis method, mathematical method, and descriptive evaluation method. The calculation to determine the level of vulnerability of pollution is the DRASTIC method for groundwater vulnerability with 7 parameters, namely groundwater depth, rainfall, aquifer type, soil texture, slope, slope, unsaturated zone type, and hydraulic conductivity. Based on the results of the study it was known that the study area had 2 classifications of the level of vulnerability of groundwater pollution, namely the moderate and high classification. Areas that are located in the direction of groundwater flow and are lower than pollutant sources will potentially be more polluted. Keywords : DRASTIC, Pollution, Groundwater, Gold Mine

Abstract

Traditional unlicensed gold mining is found in various places in Indonesia. Mining is carried out by the people and processing gold using mercury, solely to make ends meet, they do not think the impact on environmental damage and pollution and legal aspects that can ensnare it. The purpose of this paper is to evaluate the synergy of the legal umbrella and law enforcement practices in unlicensed gold mining (PETI), especially in the case of gold mining in Banyumas Regency, Central Java Province. The research method used is juridical-normative. The research data used are primary and secondary legal materials. The results showed that gold mining carried out without permission in Banyumas District was prone to cause pollution to the environment and workplace accidents. The rise of unlicensed gold mining makes it difficult for government supervision. All existing regulations and laws in synergy regulate how the people's gold mining activities should not create problems for the environment. It's just that implementation in the field is still a lot of violations, especially licensing issues. Law enforcement against illegal gold mining is carried out with preventive and repressive measures. Keywords: Banyumas, Law Enforcement, Gold Mining.
