  Archive. WQI results in 8 urban lakes in South Tangerang City  Water Quality Index (WQI) measurement results in the lakes ranged from 61.18-79.53. PJL, GL, KL and PAML lakes had values >71 within the good category otherwise. Furthermore, PARL, RL, BL and CL had values >51 within the medium category. An assessment of water quality in 8 urban lakes in South Tangerang City was conducted, as their condition was a concern. This research aims to assess water quality based on the condition of chemical-physical variables and phytoplankton composition. This research was conducted from late May to early October 2021 (the dry season until the inter-seasonal period). The Water Quality Index (WQI) ranged from 61.18-79.53 (medium-good). Phytoplankton composition consisted of 65 genera from 11 classes and 6 divisions. Oscillatoria, Euglena and Pediastrum were the dominant genera, meanwhile, Cyanophyceae and Chlorophyceae were the dominant class. Phyt...

  Archive Percentage of total AL cover. This study on Anthropogenic Litter (AL) was conducted at 5 stations in Situ Gintung, South Tangerang, Indonesia, during the dry and rainy seasons between May to July 2015 and February to April 2016, respectively. The objectives were to determine the correlation between temporally and spatially distributed AL items with gastropods and bioassessment of lake from AL. Generally, the AL consisted of plastic products, rubber, cans, paper, and glass, where plastic bags were discovered more during the two seasons at insignificantly different quantities (p>0.05) and all stations at significantly different amounts (p<0.05). The total number and percentage AL cover with gastropods had a low linear regression value and increased by more than 80% during the rainy season. Meanwhile, the difference in the number of AL was insignificant by season but significant based on the station. Although AL had little effect on gastropods, the number of individual...
