Uji Tanaman Talas (Colocasia Esculenta) Sebagai Agen Fitoremediasi Air Sungai Cikapundung

Abstract

Pollution of rivers due to the accumulation of domestic and industrial wasteis aserious challenge to the survival ofaquatic biota. Domestic waste/ household is often thrown into the water can interfere waters ecosystems. So far, many efforts have been done such as installation integrated waste treatment, but these efforts are not yet fulfill the requirement due to low awareness and lack of oversight agencies. One of the efforts to reduce domestic wasteis by making use of plant biology irrigation with Colocasia esculenta. Study ofutilization of aquatic plants for domestic wastewater treatment systems biology irrigation was conducted to determine the efficiency of nutrient uptake by C.esculenta. The research method was applied by growing C.esculenta in an experimental container -carrying raceways domestic wastewater system with subsurface flow (SSF). The results showed that physical C.Esculenta may grow well on substrates containing water Cikapundung river compared to C.Esculentagrown ona substrateis added waterwells. This is shown by the differences in growth and weight of the plants. The results of the Laboratory analysis of organic carbon (C-organic), nitrogen (N-kejdahl) and phosphate (P) on the taro plant (the leaves and roots) showed an increase nutrient in plant tissues which is directly proportional to the growth of taro plants (taro plant height and weight), as shown by a concentration of 2000 mg C sequestration and N100 mg for 63 days
