This river is suspect to receiving waste came from plastic industry activity which is streamed to the water, and also receiving household waste stream and there are plenty of water transportation in the section of the estuary. Waste from the industry is suspected contain heavy metals cadmium and lead.The study was conducted in April 2016 - May 2016 in the River of Silandak which aimed to determine the concentration of cadmium and lead, to determine the abundance and the phytoplankton community structure, and to determine the correlation of cadmium and lead with the abundance of phytoplankton. The study used survey method with purposive sampling technique. The results showed the concentration of cadmium in the study locations was within the range of 0.0007 to 0.001 mg/l, while the concentration of lead was within the range of 0.002 to 0.007 mg/l. The abundance of phytoplankton ranged between 1826 - 6730 ind/l, the rate of diversity index (H’) was within the range of 1.747 - 2.828, the dominance index (d) obtained results within the rate of 0.077 - 0.284, and evenness index (e) within the rate of 0.645 - 0.890. There was no significant correlation between cadmium with the abundance of phytoplankton with a correlation coefficient (r) of 0.179 which means weak correlations. There was no significant correlation between the heavy metals lead with the abundance of phytoplankton, the rate of the correlation coefficient (r) of 0.261 which means weak correlations.

ABSTRACT
Silandak river is located in Semarang, Central Java. This river is suspect to receiving waste came from plastic industry activity which is streamed to the water, and also receiving household waste stream and there are plenty of water transportation in the section of the estuary. Waste from the industry is suspected contain heavy metals cadmium and lead.The study was conducted in April 2016 - May 2016 in the River of Silandak which aimed to determine the concentration of cadmium and lead, to determine the abundance and the phytoplankton community structure, and to determine the correlation of cadmium and lead with the abundance of phytoplankton. The study used survey method with purposive sampling technique. The results showed the concentration of cadmium in the study locations was within the range of 0.0007 to 0.001 mg/l, while the concentration of lead was within the range of 0.002 to 0.007 mg/l. The abundance of phytoplankton ranged between 1826 - 6730 ind/l, the rate of diversity index (H’) was within the range of1.747 - 2.828, the dominance index (d) obtained results within the rate of 0.077 - 0.284, and evenness index (e) within the rate of 0.645 - 0.890. There was no significant correlation between cadmium with the abundance of phytoplankton with a correlation coefficient (r) of 0.179 which means weak correlations. There was no significant correlation between the heavy metals lead with the abundance of phytoplankton, the rate of the correlation coefficient (r) of 0.261 which means weak correlations. PCA (Principle Component Analysis) is used to determine the correlation cadmium and lead with the abundance of phytoplankton genus. There was a significant correlations of heavy metals lead with the abundance Dyctyocha sp and Bacteriastrum sp genus at 0.05 levels the range of 95%, a strong negative correlation with a correlation coefficient of -0.68.
