Keterkaitan Kelimpahan Makrozoobenthos Dengan Kandungan Bahan Organik Sedimen Di Zona Intertidal Pantai Selat Baru Kabupaten Bengkalis Provinsi Riau
Selat Baru Village was one of several beaches on Bengkalis Island which
was located in the northern part of Bengkalis Island. Selat Baru Beach as a tourist
spot that has the most visitors every day, especially during the Eid holidays. In
addition, there are rivers, ports, and boat crossings also taking place on the Selat
Baru Beach. The purpose of this study was to determine the content of sediment
organic matter, the type and abundance of macrozoobenthos, and to determine the
relationship between the organic matter of sediment and the abundance of
macrozoobenthos in the New Strait coastal waters. The method used was a survey
method, where the data collected was primary data which was then analyzed
statistically and discussed descriptively. The results of measurements of
oceanographic parameters from the research location have an average temperature
of 28.67 oC, and pH of 7, salinity of 26.33 o/oo, transparancy of 24.33 cm, and a
current velocity of 0.1 m/s. The average sediment content obtained at station 1 was
1.42%, station 2 was 0.77%, and station 3 was 7.34%. The percentage of sand
fraction has the highest percentage at station 1 substation 3 (95.56%) and the lowest
at station 3 substation 3 (39.78%), while the highest percentage of mud fraction was
at station 3 substation 3 (54.19%) and the lowest found at station 2 substation 1
(4.15%). The macrozoobenthos found were from the Bivalva class (Corbicula sp,
Lucinidae sp, Anomia sp) and the Gastropod class (Nucella sp, Rabdotus sp,
Cerithidea sp) and the Malacostraca class (Hermigrapsus sp). The average
abundance of macrozoobenthos found at station 1 was 4.22 ind/m2, station 2 was
4.22 ind/m2, and station 3 was 10.67 ind/m2. The result shows the effect of the
sludge sediment fraction on the abundance of macrozoobenthos has a coefficient of
determination (R2) with a value of 0.9015 and a correlation coefficient (r) with a
value of 0.9495 meaning that 90.15% of macrozoobenthos abundance was
influenced by sediment fraction and the rest was influenced by other environmental
factors.
