Seasonal variation of water quality of three urban small lakes in West Java, Indonesia

Abstract

Urban lakes play an important role in supporting quality of human life. There are more than 200 urban lakes in Jabodetabek areas, some of which are experiencing high risk of disappearance due to pollution, eutrophication, and sedimentation. There have been limited long monitoring of limnological data on appropriate management practice to protect the integrity of this vulnerable system. This aim of study is reveal seasonal variations of water quality in Lake Cibuntu Lake Dora, and Lake Lotus in Cibinong, West Java to support the management strategy of lakes. Water quality data including water depth, conductivity, Total Dissolved Solid, pH, Dissolved Oxygen, nutrient, were collected biweekly from July 2018 to July 2019. This result revealed that Lake Cibuntu and Lake Lotus have high variability of water depth compared to Lake Dora with the range 31 to 120 cm, 32 to 84 cm and 72 to 113 cm. The dynamic of water depth seems having an effect to the water quality variability in observed lakes. In term of nutrient, it showed a different pattern of variability fluctuation between observed lakes. The pattern of seasonal variability of water quality appeared to be related with seasonal of the year and water source.
