Description :
Pengolahan air limbah dengan memanfaatkan tumbuhan air, Reed dan
Cattail, dalam sistem constructed wetland untuk
penurunan COD {Chemical Oxygen Demand) dan TSS {Total Suspended
Solid), merupakan pokok bahasan dalam
penelitian ini. Penelitian ini bertujuan untuk mengkaji laju
serapan {specific utilization rate ; SUR), dan
membandingkan kemampuan tumbuhan Cattail dan Reed serta
pertumbuhannya.
Penelitian ini dilakukan dalam skala laboratorium, dengan
percobaan secara batch, untuk mengkaji laju serapan (SUR)
dengan variasi konsentrasi COD 200 mg/1 dan 400 mg/1 dengan
tumbuhan Cattail dan Reed. Percobaan secara kontinyu
dilakukan untuk mengkaji kemampuan tumbuhan untuk menurunkan
konsentrasi COD dan TSS, dengan variasi
konsentrasi COD 200 mg/1 dan 400 mg/1 , waktu detensi (td) 1
hari dan 3 hari, dengan tumbuhan Cattail dan Reed.
Berdasarkan hasil penelitian dengan percobaan secara batch, laju
serapan Cattail lebih besar, yaitu 11,51 mg/mg/hari
dengan COD 200 mg/1. Sedangkan laju serapan lebih kecil oleh
Reed sebesar 3,32 mg/mg/hari pada COD 400 mg/1.
Laju serapan pada konsentrasi COD 200 mg/1 mempunyai perbedaan
yang signifikan antara Cattail dengan Reed, tetapi
pada konsentrasi COD 400 mg/1, belum dijumpai perbedaan yang
berarti. Pada percobaan secara batch, kemampuan
perubahan konsentrasi COD kombinasi (tumbuhan + media tanam)
lebih besar oleh Cattail pada COD 200 mg/1, dengan
tersisa 3,80 mg/1. Sedangkan terkecil oleh Reed pada COD 400
mg/1, dengan tersisa 147,30 mg/1. Hal yang sama jugaterjadi pada
perubahan konsentrasi COD real (tumbuhan - media tanam). Pada
percobaan secara kontinyu, efisiensi
removal yang lebih besar terjadi pada td 3 hari yang merupakan
fungsi waktu. Efisiensi removal COD kombinasi, lebih
besar oleh Cattail sebesar 90,39 % dengan beban COD 200 mg/1.
Sedangkan terkecil oleh Reed sebesar 68,27 % dengan
beban COD 400 mg/1. Tetapi efisiensi removal konsentrasi COD
real, yang lebih besar, oleh Cattail sebesar 60,58 %
dengan beban COD 400 mg/1, Sedangkan terkecil oleh Reed sebesar
25,00 % dengan beban COD 200 mg/1. Untuk
efisiensi removal konsentrasi TSS kombinasi, lebih besar oleh
Cattail sebesar 79,25 % dengan beban COD 400 mg/1.
Sedangkan terkecil oleh Reed sebesar 57,58 % dengan beban COD
200 mg/1. Tetapi efisiensi removal TSS real, lebih
besar oleh Cattail sebesar 57,58 % dengan beban COD 200 mg/1.
Sedangkan terkecil oleh Reed sebesar 9,43 % dengan
beban COD 400 mg/1. Pertumbuhan tumbuhan Cattail dan Reed,
menunjukkan pertumbuhan yang positif, terhadap
beban konsentrasi COD. Namun pertumbuhan yang lebih baik terjadi
pada tumbuhan Cattail pada beban konsentrasi
COD 200 mg/1.
Description Alt:
The main topic of this thesis is wastewater treatment using
aquatic plants, reed and cattail, in constructed wetlands, for
Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS)
removal. This thesis measured the performance and
growth between cattail and reed.
This research was done in laboratory-scale, with batch
experiments to examine the Specific Utilization Rate (SUR) with
the variation of COD concentration (200 mg/L and 400 mg/L) and
the types of plant (reed and cattail). Continuous
experiments were done to examine plant ability to reduce COD and
TSS concentration, with the variation of COD
concentration (200 mg/L and 400 mg/L), detention time/td (1 day
and 3 days), and the types of plant (reed and cattail).
As a result of the batch experiments, it was discovered that the
utilization rate of cattail is fester (11.51 mg/mg/day) thanthat of
reed-on 200 mg/L of COD concentration. The reed utilization rate is
a smaller number, 3.32 mg/mg/day on 400
mg/L COD. At COD concentration of 200 mg/L there is a
significant difference between the utilization rate of cattail

and reed, but not at 400 mg/L COD. From the batch experiments it
is found out that the ability to reduce COD
concentration with the combination of plant and planting media
is greater if performed by cattail, which succeeded to
reduce COD concentration from 200 mg/L to remaining 3.80 mg/L,
while reed performed the highest reduction of 400
mg/L COD concentration to remaining 147.30 mg/L. The same thing
occurred for the real reduction of COD
concetration (plant without planting media). The continuous
experiments showed that higher removal efficiency took
place on 3 days detention time and is a function of time. The
combination removal efficiency is higher when performed
by cattail, 90.39 % on 200 mg/L COD loading, while the lowest
(68.27 %) was obtained by reed on COD loading of 400
mg/L. But the real COD removal efficiency was higher when
performed by reed (60.58 %) on 400 mg/L COD loading.
The lowest removal efficiency of 25.00 % was performed by reed
on 200 mg/L COD loading. For the combinationefficiency of TSS
concentration removal, it was higher when performed by cattail,
79.25 % on 400 mg/L COD loading,
while the lowest was by reed, 57.58 % on 200 mg/L COD loading.
But the real TSS removal efficiency was higher
(57.58 %) by cattail on 200 mg/1. COD loading, while the lowest
(9.43 %) was by reed on 400 mg/L COD loading. The
growth of cattail and reed showed a positive response concerning
COD concentration loading. But better growth was
performed by cattail on 200 mg/1 of COD concentration
loading.
