Struktur Komunitas Makrozoobentos Di Zona Intertidal Perairan Desa Api-Api Kecamatan Bandar Laksamana Kabupaten Bengkalis
ABSTRACK
This research aims to analyze the structure of macrozoobenthos community
in the intertidal zone of Api-Api Village waters, Bandar Laksamana District,
Bengkalis regency. There were 5 subzones determined as the observation areas. Each
subzone consists of 5 subplots which taken parallel to the coast with a distance of 10
meters from each subplot. The types of macrozoobenthos found consisted of 4
classes, 19 families, and 23 species. The diversity index for each subzone ranged
from 2.72 to 3.55, species uniformity index ranged from 0.78-0.91 and dominance
index ranged from 0.11-0.19, with the criteria of a uniform distribution pattern. The
highest macrozoobenthos density was in subzone 1 with a total density of 19.6
ind/m2, while the lowest was in subzone 4 with a total density of 10.6 ind/m2. The
result of statistical tests using Analysis of Variance (ANOVA) at a confidence
interval of 95% (ɑ = 0.05), showed that macrozoobenthos density in subzone 1,2,3,4
and 5 was not significant in different (P = 0.824), which means that there was no real
different density that five subzones.
