Abstract
Urban lakes are experiencing various kinds of problems because of the anthropocentrism of environmental management. This also happens in Situ Gintung, Indonesia. This lake is polluted by many pollutants from urban activities, such as the entry of domestic waste into waters due to anthropogenic activities and the amount of leftover food not consumed by fisheries. These problems can be solved by observing the water quality of Situ Gintung to provide information about parameters that have exceeded environmental quality standards and provide general information about the water quality in the dry season from 2017 to 2020. The research is done using a purposive sampling method and determining water quality status with the STORET method based on the Indonesian standard with parameters less than ten. As a result, Situ Gintung water is neither classified as class I, II, III, and IV nor be utilized for consumption, recreation, fisheries, and irrigation because the quality status is mostly in the heavily polluted category. Furthermore, the three highest polluters from each class are BOD5, COD, and a total of Coliform.
Highlights
One of the development activities in urban areas which interferes with the environmental quality occurs in urban lakes
The monitoring of water quality has 3 primary objectives: understanding the water quality based on science parameters, comparing water quality values with the quality standards from Indonesian Government Regulation Number 82/2001 (Appendix 1), and assessing the suitability of water for particular interests [17]
This decree classifies water quality standards according to their designation into 4 classes as follows: 1. First-category, water can be drunk from the raw condition; 2
Summary
One of the development activities in urban areas which interferes with the environmental quality occurs in urban lakes. Millions of cubic meters of water flooded the settlements in the northern part of the area (Ministry of Public Works and Housing; Indonesian Architects Association, 2009) and caused more than a hundred fatalities and injured in this disaster [10] In this case, the Situ Gintung function additions do not consider the balance factor between humans and the environment yet. To maintain the balance of the environment, especially in urban lakes, monitoring of periodic water quality, based on physical, chemical, or biological parameters, is required to provide the necessary data to protect the environment from various contaminants These contaminants possibly come from anthropogenic activities [12][13], including household activities (bathing, cooking, and washing), littering into rivers, and disposing of wastewater from households [2], [12], [14]. The data will show the exact condition of Situ Gintung water
