Abstract

This research was conducted in May 2009 in between District AekManis waters Sibolga North Sumatera in order to determine the correlationsediment organic material content and makrozoobenthos abundance.Determinantion of the research station was randomly composed of 4 station and 5sampling point where each point sampling distance of 200 meters wich werebased on the initial sampling paoint. Makrozoobenthos encountered and thestudy area there 26 genera of 3 classses, namely class gastropoda, bivalve.Polychaeta. Individuals from the class of individuals who gastropoda us mostoften found. On the whole it can be seen that the relation between sediment organicmaterial content and makrozoobenthos abudance show a positive correlation, thehighercontent of organic material wiil lead to the higher of the makrozoobenthosabundance.

Abstract

This research was conducted in May 2017 located on the coast of West Dumai Subdistrict, Riau Province. This Study aims to determine the relationship between the abundance of phytoplankton and the level of primary productivity in coastal waters of Dumai Barat District, Riau Province. The method used during this research is a survey method and the determination of station points by purposive sampling. Sampling of water quality parameters in situ. The results of the calculation of phytoplankton abundance ranged from 6,200 mg/l and phytoplankton species were found the most from the Bacillariophyceae class of 14 species. Simple linear regression test results of the relationship of abundance of phytoplankton with primary productivity at each station are shown by the mathematical equation Y 1.2911x + 2.8 with the coefficient of determination (R2) 0.1839. It can be concluded that the higher the abundance of phytoplankton, the higher the level of primary productivity.
