FITOREMEDIASI HASIL PENGOLAHAN LIMBAH LINDI MENGGUNAKAN ECENG GONDOK ( Eichornia crassipes)
Yogyakarta has a Final Processing Site (TPA) located in Bantul Regency, namely Piyungan TPA. The DIY Regional Government stated that the average volume of waste in Piyungan TPA that enters per day is more than 700 tons with a storage height of 140 m, while the TPA's capacity is designed to accommodate 650 of waste tons/day. Suboptimal waste management in the TPA can cause waste piles to increase and produce leachate. Leachate is very destructive and must be processed and treated before being disposed of. Efforts that can be made to reduce pollutants in leachate include phytoremediation using eceng gondok ( Eichhornia crassipes ). This study aims to determine the effect of variations in leachate concentration on the morphology of eceng gondok ( Eichhornia crassipes ), changes in DO, BOD, pH, temperature, and Pb parameters at each concentration, and the most improved parameter changes. The method used is static phytoremediation, with observations of morphological changes (leaves and stems), DO, BOD, pH, temperature, and timbal (Pb). The results of the study showed that there were morphological changes, both leaves and stems experienced chlorosis and decay because water hyacinth is very susceptible to leachate content. In addition, all test parameters showed values below the predetermined quality standards from Peraturan Daerah Daerah Istimewa Yogyakarta No. 7 Tahun 2016. DO, BOD, pH, and temperature parameters had lower values than the control. Showing that the presence of water hyacinth has an effect on changes in test parameters. Based on the research that has been done, it shows that the presence of water hyacinth in the phytoremediation process, BOD and DO levels increased, pH and temperature decreased while Pb (timbal) levels did not change.
