DETERMINATION OF SURFACE WATER QUALITY BASED ON MACROZOOBENTHOS BIODIVERSITY AND THE PREVALENCE OF TREMATODES CERCARIAE IN FRESHWATER MOLLUSCS

Lake Cisanti is the upstream of Citarum River and silting has occurred in inlet areas. This water body was selected as research area due to its crucial role for people living West Java Province despite some pollution issues recently. The conducted from January May 2016 during rainy season. aim it assess quality reveal that Trematodes cearcariae could be used bio indicator organic pollution. From identification results, there were 31 morphospecies macrozoobenthos seven classes found Cisanti. Melanoides tuberculata had highest total density (188 ind/m2). It implied matter open defecation polluted Based on value CCMEWQI, H’, FBI, can concluded comprehensively unpolluted January-May 2016. Water conductivity carbon sediment strongest correlation with biodiversity In order understand main factors physical chemical parameters influencing biodiversity, Principal Component Analysis (PCA) required. PCA two parameters, F1 (consist turbidity COD) F2 temperature conductivity). Those explain 73.268% variance all parameters. Furthermore, overall prevalence Trematode cercariae Molluscs about 5.49%. There significant strong between fecal coliform concentration based Spearman analysis. considered a pollution, even though further needed test various aquatic ecosystems, both laboratory (man-made ecosystem) natural ecosystem scales.
