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.
