Abstract

This research is intended to know density and diversity species of makrozoobenthos in the Jenggalau River which contaminated by PDAM’S pollutant, and in the river that uncontaminated by PDAM’s pollutant. This research was conducted from May to June 2011. Samples were collected by using purposive and random sampling methods at two differents stations. As a result, makrozoobenthos found at station 1 (one) were 4 genera: Thiara, Lydores, Goniobasis, and Apella. Station 2, there were 4 genera: Macrobrachium, Macromia, Gomphus, and Parathelphusa. The highest value of Population Density and Relative Density at station 1 was aquaired from genus Thiara (PD = 3.23, RD = 33.105%) and the lowest by Apella (PD = 1.36, RD = 13.993%) at station 2. The highest value of PD and RD was aquaired from genus Machrobrachium (PD = 1.26, RD = 48.101% and the lowest by genus Parathelpusa (PD = 0.36, RD = 13.924%). Index Diversity (H’) was 4.909 at station 1 and 1.699 at station 2. Index Similarity (E) was 3.541 at at stations 1 and 1.225 at station 2.
