ABSTRACT
Kreo River is an ecosystem in which there are several interacting components. Nitrate and phosphate nutrients are usually contained in water and sediments. The role of nitrate phosphate contained in sediments in rivers is an important element for the growth and survival of aquatic microorganisms. The purpose of this study was to determine the concentration of nitrate, phosphate sediment and the type of sediment texture in Semarang Kreo River. As well, to investigate the abundance and diversity of macrozoobentos in the Semarang Kreo River, analyzing the relationship of nitrate and phosphate concentrations in sediments with abundance of macrozoobentos in Semarang Kreo River. The study method was used the explanatory method. Sampling was used purposive sampling technique. Data analysised were multiple linear regression test with SPSS 16 software. The results of study showed that the concentration of nitrate was around 0.14 mg/l - 0.63 mg/l. Phosphate concentrations ranged from 0.01 mg/l - 0.11 mg/l. Station I sediment types: sandy clay loam, station II: clay sand and station III: sand. Macrozoobentos genus found were the gastropod class (Sulcospira sp, Melanoides sp, Brotia sp, Annetome sp, Tarebia sp). The diversity of macrozoobentos is included in the low diversity (0,23-0,25). The strong relationship was found between nitrate phosphate concentration and the abundance and diversity (r = 675).
