Phytoremediation of domestic wastewater (detergent) with arrowhead and burhead plants in Purwodadi Botanic Garden

Abstract

The aquatic plants is use for reduce the organic materials levels contained in the domestic wastewater. Some aquatic plants can be used as a phytoremediator in an effort to overcome water pollution, one of them is Arrowhead (Sagittaria lancifolia) and Burhead (Echinodorus radicans). The aim of this research is to know how Arrowhead and Burhead plants as phytoremediation of domestic wastewater (detergent) in Purwodadi Botanic Garden. The design of this study was Randomized Block Design (RAK) with 2 factors: crop treatment on medium and locus of domestic wastewater concentration (detergent) 0 g/L (as control); 0,05 g/L; 0,1 g/L; 0,15 g/L. The data observation are plant morphology, plant water level, plant biomass at the beginning and end of environment and environmental parameters such as temperature and humidity. The results obtained were no significant morphology of Echinodorus radicans plants observed in green and fresh colours, for water levels of 0,05 g/L, decreased by 0,5 cm, concentrations of 0,1 g/L down 0,6 cm, concentration 0,15 g/L down 1 cm. At the observation of biomass difference of 0,05 g/L concentration of 3,6 g; 0,1 g/L concentration of 5,6 g; 0,15 g/L concentration of 8,6 g. On observation the average temperature is 22-25°C and the moisture average 52-64%. The results obtained were for morphology Sagittaria lancifolia mortality rate, for water level with concentration 0,05 g/L, amount 0,4 cm; concentration 0,1 g/L or decreased 0,3 cm; concentration 0,15 g/L decreased 0,4 cm. At the observation of biomass difference of 0,05 g/L concentration of 5,5 g; 0,1 g/L concentration of 3,5 g; 0,15 g/L concentration of 39,7 g. On observation the average temperature is 22-25°C and the average moisture averages 60-64%.
