KEANEKARAGAMAN JENIS MAKROZOOBENTHOS SEBAGAI BIOINDIKATOR UNTUK MENGETAHUI TINGKAT PENCEMARAN DI MUARA SUNGAI JENGGALU KOTA BENGKULU

This research was intented to investigate species diversity of makrozoobenthos at three
different stations in estauria of Jenggalu Bengkulu. Research was carried out on May-July
2011 by using Randomized Sampling Method. As the result, there were 3 fillum, 4 classes,
11 families, 13 genera, and 14 species of makrozoobenthos lived in Estuaria Jenggalu. They
were distributed at Station 1 as much as 3 fillum, 4 classes, 7 orders, 10 families, and 11
species, with the highest abundance aimed at Nereis virens (28.5%), Diversity Index was
1.19, Similarity Index was 0.49 and Dominance Index was 0.26. The highest abundance at
Station 2 was Tellina sp (20.27%), with Diversity Index was 1.69, Similarity Index was 0.66
and Domination Index was 0.26. While Station 3, there were 3 fillum, 4 classes, 8 families
and 9 species with the highest abundance aimed at Penaeus sp (25.4%), Diversity Index was
1.47, Similarity Index was 0.61, and Domination Index was 0.20.
