Correlation of lead and zinc contents in sediments and faunus ater against faunus ater density in reuleung river, leupung, aceh besar

Abstract

Purpose-The purpose of this research is to investigate the relationship of lead (Pb) and zinc (Zn) contents in sediment of Faunus ater (F. ater) population density and to analyze the relationship between Pb and Zn accumulation in F. ater with F. ater density in Reuleng River, Leupung, Aceh Besar. Design/Methodology/Approach-Sampling was conducted in November 2016 until January 2017. Density of F. ater was analyzed by density formula while its relationship to Pb and Zn in sediments and F. ater was conducted by correlation analysis method. Findings-The results showed that correlation between Pb and Zn in sediments and in F. ater varies at each locations on every month of sampling. Pb and Zn content in sediments found a fluctuating relationship in each month of sampling with density of F. ater. Correlation of Pb content in sediments with F. ater density showed a medium correlation in January 2017 with r-value 5 0.665. Zn in sediment has a very strong correlation to F. ater density in November 2016 with r-value 5 0.891. Pb in F. ater has a medium correlation to F. ater density in January 2017 with r-value 5 0.436. Furthermore, accumulation of Zn in F. ater to its density does show some apparent correlation in each month of sampling. Research Limitation/Implications-This research gives information about the relationship of Pb and Zn contents in sediment to density of F. ater and to analyze correlation of Pb and Zn in F. ater to density of F. ater in Reuleng River, Leupung, Aceh Besar district. Originality/Value-This is the first time research is conducted about on the correlation between lead and zinc to obtain the density of F. ater.
