Evaluation of the Phytoremediation Potential of Pegaga (Centella asiatica) under Shrimp Farm Effluent

Abstract

AbstractThe commercial aquaculture sector in culturing shrimp (Macrobrachium rosenbergii) may be increased contaminants in the waterbody without proper treatment. Our research is directed to examine the morphology and the survival rate of wetland plants as Centella asiatica had a fresh weight 20.73 ± 0.019 g, length of tree 23.5 ± 0.17 cm, and length of roots 4.5 ± 0.03 cm (e.g., a plant group/reactor) for raising in an aquarium containing 7 L of shrimp farm effluent in a period from the start time to the 15 days. In the experimental design, the Control aquarium is a non-planted aquarium (n = 2), and the Experiment aquarium is an aquarium planted with Centella asiatica (n = 3). Physical and chemical indicators are temperature, pH, EC, TDS, and DO for daily monitoring in a period from the start time to fifteen dates. Water samples are collected on the start time, 5 days, 10 days, and 15 days for analysis of indicators ammonium-nitrogen (NH4+-N), phosphate (PO43−), iron (Fe), and copper (Cu). The findings show that C. asiatica grow well in the shrimp farm effluent with 100% high survival rate, especially a new plant that grows from a vegetative part of C. asiatica (i.e., it is usually a stem of the parent plant of C. asiatica) on the 10 days and 15 days. In conclusion, C. asiatica has the capacity to adapt and remove NH4+-N and PO43− pollutants under static conditions. The growth and development of C. asiatica have a positive effect on reducing pollutants from shrimp farm effluent for 15 days experiments as phytoremediation potential of biological treatment.KeywordsPhytoremediationShrimp farm effluent Centella asiatica
