The Covid-19 pandemic has caused the use of detergents increased. Detergent waste causes a decline in quality of water, resulting in a decline in water biologic diversity. Sunda prawn (Macrobrachium sintangense De Man) is a native Indonesian prawn. The prevalence of this prawn is currently decreasing. When aquatic organisms are exposed to pollutants, a series of biological events occurs if the exposure concentration is high enough and the exposure duration is long enough. This study aimed to determine the concentration of detergent waste that resulted in 50% mortality of sunda prawn at 96 hours (LC50−96 H), and to determine structural changes/damage to the gill tissue of sunda prawn (M. sintangense) due to the influence of detergent. The research method to determine the value of LC50−96 H was to follow the USEPA procedure with the renewal static test type. The analysis of damage to the gill tissue of sunda prawn (M. sintangense) carried out by microscope observation, using the paraffin method. The research was conducted in August 2021. Based on the results of the analysis, the LC50−96 H value obtained in sunda prawn (M. sintangense) test was 180.702 ppm. The LC50−96 H value is in the concentration range of 2.098 ppm to 213.068 ppm at a 95 % confidence level. Water quality criteria for toxicants can be determined from 1% LC50−96 H value. The LC50-96 H detergent concentration which is classified as safe for sunda prawn is 1.81 ppm. The condition of the gills and gill lamellae were swollen and damaged. The gills exposed to detergents experienced a state of hyperplasia, necrosis and fusion. [ABSTRACT FROM AUTHOR] |
