Abstract

Landfills are one of the causes of environmental pollution resulting from the disposal of human activity waste without further treatment (Yusri et al., 2020). In 2023, the total waste generation reached 1,270.00 tons per day, with 900 tons of waste being transported to the landfill each day (Harjanti, 2020). This waste accumulation produces leachate—a thick, dark-colored liquid that carries pollutants and materials from the waste—which has the potential to contaminate the surrounding environment, including the Kreo River. Therefore, phytoremediation using Mendong plants is proposed to reduce the pollutants in the leachate. This research employed an experimental method with a Completely Randomized Design (CRD), using Mendong plants (Fimbristylis globulosa) and three biomass variations: P0 (0 g), P1 (1000 g), and P2 (2000 g). Each treatment involved 10 liters of leachate and was replicated three times. The phytoremediation process proved effective in reducing total ammonia levels in the leachate, with a reduction of up to 63%, and the highest total nitrogen reduction reached 53%. This phytoremediation approach can assist in reducing excess total ammonia in water bodies by absorbing organic pollutants through plant roots, as Mendong exhibits hyperaccumulator and hypertolerant properties. It is concluded that Mendong plants are effective in lowering total ammonia and total nitrogen levels in landfill leachate.

Abstract

Leachate is  a liquid with an unpleasant odor and dark color that generally contains high organic and inorganic matter. High levels of organic and inorganic matter in leachate will potentially cause environmental pollution if not treated properly. One of the efforts that can be made to overcome these problems is with phytoremediation techniques. This study aims to determine the effectiveness of water bamboo (Equisetum hymale) as a phytoremediation agent  of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) leachate of Jatibarang landfill. This study used experimental research with a one-factorial Complete Randomized Design (RAL) design with three treatments (P0 without water bamboo, P1 750 gr water bamboo, and P2 1000 gr water bamboo). Based on the results of research shows that water bamboo plants can reduce BOD and COD levels. The decrease in leachate BOD levels was caused by the phytoremediation process by water bamboo during the study, where the organic matter content in leachate would be degraded by microorganisms. Meanwhile, COD levels decreased due to the chemical oxidation reaction process and phytoremediation process that runs side by side. The effectiveness of reducing BOD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 28.42%; while the percentage of effectiveness of reducing COD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 39.14%
