STUDY BETWEEN OIL CONTENT SEAWATER AND DIATOMS ABUNDANCE IN AIR HITAM STRAIT MERANTI ISLANDS REGENCY RIAU PROVINCE

Abstract

The research was conducted on February until March 2017 with a goal to
determine the relationship between the oil content and the abundance of diatoms,
in Air Hitam Strait Meranti Islands Regency Riau Province. The survey method
were conducted in four stations, in which three sampling. It revealed t hat the oil
content of water ranged (0.2687 to 0.7889 ppm) and diatom abundance between
(116 to 287 cells/l) which contain of 7 species. Of research results, the oil
content in the sea water with an abundance of diatoms have a strong relation with
the value of the correlation coefficient r = 0.727, regression equation appeared y
= 337.04 – 233.71 x with a coefficient of determination (R2) = 0, 5291 and the
value of the Sig < 0.05. It was suggested that increasing oil content will decrease
the abundance of diatoms in the Air Hitam Strait.
Key Words: abundance, diatoms, oil content
