Abstract

Aquatic Primary Productivity is a process of organic compounds forming through the process of photosynthesis. Siombak Lake is one of the artificial lake in Medan Marelan District of Medan City which is to be used by the community for tourism, fishing activity, and household disposal cesspit so that give negative impact to the water. This research aims to determine the rate of aquatic primary productivity in Siombak Lake and to determine the relationship between aquatic primary productivity with Chlorophyll-a and Physical Parameters of Aquatic. The research was conducted in February – March 2017. The method used in this research is purposive sampling method which is devided into three stations based on different activities. The analysis used were primary productivity analysis, water quality, chlorophyll-a, and pearson correlation. The condition of Siombak Lake is classified as medium polluted with dissolved oxygen value (DO) has an average value of 3.08 mg/L. Based on its Primary Productivity value of Lake Siombak pertained Mesotrophic Lake with average value of 1005,9648mgC/m3/day, with the average value of chlorophyll-a is 4,108 mg / m3. The Relationship betweenthe rate of aquatic primary productivity with chlorophyll-a and the aquatic chemical physics parameters at Siombak Lake is very strong.Keywords : Primary Waters Productivity, Chlorophyll-a, Physical ChemicalFactor, Lake.
