Small lakes are important freshwater resources to support the quality of human life. However, small lakes in the watershed are becoming threatened ecosystems because of increasing land-use changes and anthropogenic activity. The study aimed to determine characteristic physical-chemical parameters and trophic status some small lake in Ciliwung Watershed to support the sustainable management of small lakes in the Ciliwung watershed in preventing eutrophication effects.  The data was collected in April and June 2021. Measurement and analysis of water quality parameters were conducted by insitu and Laboratory. Some parameters were not in accordance with the Government Regulation number 22/2021 for class II water quality criteria (WQC), including TSS (>50 mg.L-1)., TP (>0.03 mg.L-1), COD (>25 mg.L-1) and DO (<3 mg.L-1), especially for Lake Sunter and Lake Cincin.There are two groups of lakes based on water quality and trophic status. Lake Telaga Warna Lake Cikaret, and Lake Cilodong were classified as eutrophic while lake Sunter and Lake Cincin were classified as hypereutrophic lake Lake Telaga Warna, Lake Cikaret, and Lake Cilodong, located at the upper and middle watershed, are eutrophic, characterized by deeper bottom and higher Secchi depth. At the lower watershed, Lake Sunter and Lake Cincin are hypereutrophic characterized by higher nutrients (TN and TP), COD, temperature, conductivity, salinity, and TDS. The downstream area was a densely populated area that contributed high pollution from upstream and middle of Ciliwung watershed.

Artisanal Gold Mining

Introduction: Unsustainable natural resources utilization is on the increase in the developing countries thus the ability of many local communities to meet their basic needs including food, water and shelter is jeopardized. Uncontrolled gold-mining in Sikasso region is one such an anthropogenic activity that is of great environmental concern to the local and national governments of Mali owing to its potential impacts on water quality, human health and environment. This study was conceived to assess the impacts of artisanal gold mining on water quality in Tangandougou in Sikasso region of Mali.Materials and Methods: In this descriptive study, water samples were collected, processed and analyzed for heavy metals (Lead, Cadmium and Arsenic) according to APHA protocols. Measurements of physical parameters of water quality were done according to APHA protocols. Data were analyzed using both descriptive and inferential statistics.Results: There were no significant spatial differences in physical and chemical parameters (pH, Temperature, Conductivity, total dissolved solids and Salinity) of water quality amongst the sampling sites. However, the heavy metals concentrations in the sampled water exceeded WHO drinking water quality guidelines.Conclusion: It was concluded that the water of Sankarani River and its tributaries is contaminated and may cause adverse effects on human health due to biomagnification and the bioaccumulative nature of heavy metals. Therefore, the study recommends continuous monitoring of the water quality in all water sources adjacent to gold-mining areas to protect human and environmental health.

A study of spatial and temporal variations on water quality and trophic status was conducted to determine the temporal (average reading by month) and spatial variations of water quality in Sembrong reservoir and to evaluate the trophic status of the reservoir. Water samples were collected once a month from November 2016 to June 2017 in seventeen (17) sampling stations at Sembrong Reservoir. Results obtained on the concentration of dissolved oxygen (DO), water temperature, pH and secchi depth had no significant differences compared to Total Phosphorus (TP) and chlorophyll-a. The water level has significantly decreased the value of the water temperature, pH and TP. The water quality of Sembrong reservoir is classified in Class II which is suitable for recreational uses and required conventional treatment while TSI indicates that sembrong reservoir was in lower boundary of classical eutrophic (TSI > 50).

Abstract. Rimadiyani W, Krisanti M, Sulistiono. 2019. Macrozoobenthos community structure in the Western Segara Anakan Lagoon, Central Java, Indonesia. Biodiversitas 20: 1588-1596. Anthropogenic activity along the river and around the coastal area will potentially generate waste as it can cause the decline of water quality and affect the lives of macrozoobenthos. This study aimed to study macrozoobenthos community structure in western Segara Anakan Lagoon and its relationship with water physical-chemical quality. The study was conducted from June to November 2016, at six stations of the lagoon. Macrozoobenthos obtained during the study consisted of four phyla (Annelida, Mollusca, Crustacea, and Sipuncula), six classes, and 33 genera. The highest abundance of macrozoobenthos was at Station 6 (193 ind./m2) dominated by Malacostraca and the lowest abundance of macrozoobenthos was at Station 1 (13 ind./m2) dominated by Bivalvia. Diversity, Evenness and dominance indices of the macrozoobenthos were 0.0-2.0, 0-0.8, and 0.4-1.0, respectively, indicating a medium ecologically stressed. Mud substrate condition with high percentage of organic material affected the community structure of the macrozoobenthos expressed by a high density and diversity, but low dominance indices.

The purpose of this study is to analyze the water quality of the river and the status of water quality of watersheds Kundur Kabupaten Labuhanbatu. Sampling was done at 3 monitoring points along the flow of the river Kundur Kabupaten Labuhanbatu. The determination of the sampling points in the field using the purposive sampling method, with the determination of the sampling points based on the differences in the characteristics found in the study area.Some of the parameters measured were temperature, conductivity, COD, BOD, and oil/ fat are then compared with the criteria of the Raw water Quality of the river class II according to PP R. I. No. 82 Year 2001.On Water Quality Management.Based on the results of the analysis of the obtained results that in the area of monitoring point 1, is the most polluted areas.This is because, in this area there is the activity of a diverse community.Household produces waste that comes from the activity of the bathroom, toilet, kitchen, washing clothes and washing of household appliances.

Study of Water Quality in Bengalon’s River on Oil Palm Estate. Increasing of population had effect the Land cover condition and cause the polluted. Oil palm land clearing are potentially cause the pollutants in waters so that required for monitoring the quality condition. Study aims to determine the water quality based on physical, chemical and biological parameters and determine water quality standard status in accordance the Government Regulation. Research was conducted for two months in Bengalon’s River, East Kutai Regency, East Kalimantan Province. Research applies with Storet method by the reference on Government Ordinance Number 82 Year 2001, observation and documentation method, physical parameter: Temperature, TDS and TSS Turbidity, chemical parameters: pH, BOD, COD, DO, Nitrate, Nitrite, H2S as Sulfate and Iron and biological parameters: E.Coli Bacteria. The research results the waters of Bengalon’s river have been polluted by TSS, DO and Iron whereas the other parameters are still in normal condition. It showed that the waters condition of Bengalon’s river is still classified as lightly contaminated so that still can be used for class I, II, III, and IV but it provided through further processing.

Water plays a very important role in supporting human life and other living beings as goods that meet public needs. Water is one of the declared goods controlled by the state as mentioned in the constitution of the republic of Indonesia. The state control over water indicated that water management can bring justice and prosperity for all Indonesian people. However, in fact, water currently becomes a product commercialized by individuals and corporations. It raised a question on how the government responsibility to protect the people's right to clean water. This study found that in normative context, the government had been responsible in protecting the people’s right over the clean water. However, in practical context, it found that the government had not fully protected people's right over clean water. The government still interpreted the state control over water in the form of creating policies, establishing a set of regulations, conducting management, and also supervision.
