Structure of macrobenthos community has been used to determine various environmental disturbances both in farmingn (Sapto, 2007; Gonzalez and Jerez, 2011; Yokoyama et al, 2007) and industrial activities (Wijayanti, 2007; Mooraki, 2009; Amin et al, 2012). Macrobenthos are organisms that live in the mud, sand, gravel, stone or organic waste either on the basis of the aquatic environment which is capable to settle and stick to the bottom of aquatic environment (Lind, 1979). Therefore macrobenthos is an organism which is difficult to escape from environmental disturbance.
Macrobenthos animals have a variety of roles including as part of the food web of aquatic ecosystems and improve the structure of the sediment through the activity of digging, drilling, bioturbation and excretion. Through their roles macrobenthos can determine the quality of the waters between space and time to look at the structure or dominance of a taxa
(Sapto, 2014). Macrobenthos can respond quickly to changes in the environment occured through the structure and abundance changes.
