The role of nitrate and phosphate in sediments is as a nutrient needed by microorganisms for survival. The purpose of this study is to determine the concentration of nitrate and phosphate in Kaligarang waters sediments, Know the abundance and diversity of macrozoobenthos in Kaligarang and analyze the relationship of sediment fertility with abundance and diversity of macrozoobenthos in Kaligarang. The research has be done two samplings in June 2019 with a purposive sampling method. The measured variables are sediment texture, nitrate and phosphate, total organic matter, pH sediment, dissolved oxygen, and alkalinity. Data analysis using multiple linear regression analysis with SPSS 16 software. The results of studies that have been carried out nitrate concentrations ranged from 0,19 – 0,35 mg /l and phosphate concentrations ranged from 0,05 – 0,17 mg /l. Macrozoobentos found by Clea helena, Melanoides sp., Mieniplotia sp., and Tarebia sp. The highest abundance was C. helena with a value of 4044 and the lowest abundance with Mieniplotia sp with 44 individuals / m2. Diversity index macrozoobentos of 0,26 – 0,89. The correlation of nitrate correlation with abundance macrozoobentos of 0,99 is classified as high, the correlation of phosphate with abundance macrozobentos of r=0,38 is classified as low. The correlation of nitrate with diversity mcrozoobentos is low r= 0.18 and phosphate correlation with diversity macrozoobentos is high with r=0,87.
