Padjadjaran Retention basin is an inland aquatic ecosystem in the form of a water basin that was newly flooded in 2021, located in Cileles Village, Jatinangor District, used as a water storage pond, irrigation source, and fishing. Around the waters there are human activities in the form of fisheries, agriculture, livestock and construction of the Cisumdawu Toll Road which can affect water quality physically and chemically. The purpose of the study was to determine the suitability of the water quality of the Padjadjaran Retention basin for aquaculture with a sustainable floating pond system. Water samples were collected from February to March 2022. The method used in this study is a survey, sampling is carried out using a random sampling method at three stations representing inlets, midlets and water outlets, measurement of water samples is carried out in situ which includes temperature, water transparency, pH, Dissolved oxygen and Carbon dioxide and ex situ measurements include Total suspended solid, Total dissolved solid, Ammonia, Nitrite, Hydrogen sulfide and Biochemical oxygen demand at the Aquatic Resources Laboratory of Padjadjaran University and the Tirtawening Environmental Quality Control Laboratory. The data were analyzed using the Water Quality Suitability Index (WQSI) according to Costa Pierce et al (1990), water quality standards refer to the Indonesian Government Regulation Number 22 of 2021, and Indonesian National Standard number 6494: 2013. The results showed that the water quality of Padjadjaran Retention basin is suitable for use for aquaculture, it is located near the outlet are more suitable for the placement of fish farming containers with a suitability index of 0.53, compared to in the inlet and in the midlet have a suitability index of 0.18 and 0.17, respectively.
