Keanekaragaman Makrozoobenthos sebagai Bioindikator Kualitas Perairan Estuari Percut Sei Tuan Kabupaten Deli Serdang

Abstract

Percut estuary Sei Tuan has a length of 3,820 meters, is influenced by the ebb and the flow of ships, boats and there are a haven tourist activity. Macrozoobenthos diversity and the measurement of physical and chemical factors is one of the parameters used to determine changes in water quality in the estuary Percut Sei Tuan. The purpose of this study was to determine the physical and chemical waters in relation to water quality standards under PP 82 of 2001 with Storet method as well as the density and diversity of macrozoobenthos. This research was conducted over two months, from March to April 2016 in the waters of the estuary Percut Sei Tuan District of Deli Serdang. Based on the results obtained correlation between the physical and chemical waters of the estuary Percut Sei Tuan included into class C with the condition of polluted waters Medium and included into class III, water allocation can be used for the infrastructure of water recreation, the activities of pond fisheries, water to irrigate the crops or another designation similar to the usefulness and value of diversity index (H ') macrozoobenthos obtained at each station research that ranged from 1.375 to 2.050. These results indicate that the diversity of macrozoobenthos is low. Pearson correlation analysis results showed that the temperature, salinity and pH as very strong, BOD5 classified as moderate, and light penetration is low DO and COD relatively very low.
