Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana efisiensi Scirpus grossus dalam mendekonsentrasi amonium dan mengetahui laju pertumbuhan relatif Scirpus grossus dalam mendekonsentrasi amonium pada lindi. Lindi yang digunakan adalah lindi artifisial. Penelitian ini menggunakan lindi artifisial yang divariasikan antara larutan amonium dan larutan sumber karbon yaitu glukosa dan asam laktat. Pada awalnya tumbuhan ini diaklimatisasi dan range finding test. Uji fitoremediasi menggunakan reaktor reed bed evapotranspiration. Scirpus grossus dalam sistem reed bed evapotranspiration dapat menyisihkan amonium rata-rata sebesar 95% dalam 20 hari. Kemampuan Scirpus grossus saja dalam menyisihkan amonium rata-rata adalah 18,5% pada lindi artifisial dengan konsentrasi amonium sebesar 1000-1400 mg/l amonium. Larutan glukosa dan asam laktat tidak berpengaruh dalam efisiensi penyisihan amonium, karena keduanya memiliki nilai yang sama, namun larutan sumber karbon ini berpengaruh pada rasio BOD/COD. Berdasarkan hasil penelitian, rasio BOD/COD dapat ditingkatkan dengan menambahkan larutan glukosa apabila konsentrasi amonium 1000 mg/l, namun apabila konsentrasi amonium diatas 1000 mg/l dapat menambahkan larutan asam laktat untuk meningkatkan rasio BOD/COD. Laju pertumbuhan relatif Scirpus grossus selama 20 hari paling tinggi dari hasil penelitian adalah sebesar 0.18 per hari dan 0.13 per hari dari berat awal Scirpus grossus dengan konsentrasi amonium sebesar 1000 mg/l. Hal ini menandakan bahwa Scirpus grossus lebih efisien dalam menyisihkan amonium dengan konsentrasi amonium sebesar 1000 mg/l dibandingkan konsentrasi diatasnya =========== This study aims to determine how the efficiency of Scirpus grossus in deconcentrating ammonium and determine the relative growth rate Scirpus grossus in deconcentrating ammonium in leachate. This research used artificial leachate. This study used artificial leachate varied based on ammonium and the solution of the carbon source is glucose and lactic acid. At first these plants acclimatized and range finding test Phytoremediation test used reed bed evapotranspiration reactor. Based on the research results, Scirpus grossus in reed bed evapotranspiration systems has the ability to remove ammonium average of 95% within 20 days. The ability Scirpus grossus only in removal ammonium average was 18,5% in leachate artificially with ammonium concentrations of 1000-1400 mg/l ammonium. Solution of glucose and lactic acid has no effect on ammonium removal efficiency, since both have the same value, but the solution of this carbon source affects the ratio of BOD/COD. Based on the research results, the ratio of BOD/COD can be improved by adding a glucose solution when the concentration of ammonium 1000 mg/l, but if ammonium concentrations above 1000 mg/l can add lactic acid solution to increase the ratio of BOD/COD. Relative growth rate Scirpus grossus for 20 days, most of the results of research is at 0.18 and 0.13 per day of initial weight Scirpus grossus with ammonium concentration of 1000 mg/l. This indicates that Scirpus grossus more efficient to remove concentration of ammonium with ammonium concentration of 1000 mg/l compared to the concentration on it.
