Analisis Kadar Amonia Dan COD (Chemical Oxygen Demand) Dari Beberapa Air Limbah Inlet Dan Outlet Pabrik Karet

ANALISIS KADAR AMONIA DAN COD (CHEMICAL OXYGEN
DEMAND ) DARI BEBERAPA AIR LIMBAH INLET
DAN OUTLET PABRIK KARET

ABSTRAK

Telah dilakukan Analisis kadar Amonia dan COD ( Chemical Oxygen Demand)
dari beberapa air limbah inlet dan outlet pabrik karet. Kadar COD (Chemical
Oxygen Demand) ditentukan dengan metode titrasi dan Kadar Amonia di tentukan
secara spektrofotometri UV-Visible dengan panjang gelombang 640 nm. Dari
hasil analisis yang dilakukan, kadar COD pada pabrik A inlet 12,048 mg/L dan
outlet 4,016 mg/L, pabrik B inlet 642,56 mg/L dan outlet 42,256 mg/L , pabrik C
inlet 184,730 mg/L dan outlet 168,672 mg/L. Kadar Amonia pabrik A inlet 0,164
mg/L dan outlet 0,042 mg/L, pabrik B inlet 2,055 mg/L dan outlet 1,171 mg/L,
pabrik C inlet 0,319 mg/L dan outlet 0,303 mg/L. Dari hasil analisa yang
dilakukan dapat diketahui bahwa kadar Amonia dan COD pada Outlet pabrik A,B
dan C telah memenuhi baku mutu air limbah pengolahan limbah cair industri
karet bentuk kering menurut PERMEN/LH/5/2014 yaitu maksinal 5 mg/L dan 200
mg/L.

ANALYSIS OF AMONIA AND COD (CHEMICAL OXYGEN)
DEMAND) FROM SEVERAL WASTE INLET WASTE
AND OUTLET RUBBER FACTORY

ABSTRACT

Ammonia and COD levels (Chemical Oxygen Demand) have been analyzed from
some inlet waste water and rubber plant outlets. The concentration of COD
(Chemical Oxygen Demand) was determined by titration method and ammonia
level was determined by UV-Visible spectrofotometry with wavelength 640 nm.
From the results of the analysis, the COD concentration in the factory A inlet
12,048 mg / L and outlet 4,016 mg / L, factory B inlet 642,56 mg / L and outlet
42,256 mg / L, factory C inlet 184,730 mg / L and outlet 168,672 mg / L.
Ammonia Factor A inlet 0,164 mg / L and outlet 0,042 mg / L, factory B inlet
2,055 mg / L and outlet 1,171 mg / L, factory C inlet 0,319 mg / L and outlet

0,303 mg / L. From the analysis result, it can be seen that Ammonia and COD at
Factory Outlet A, B and C have fulfilled wastewater standard of waste water
treatment of dry industrial waste rubber industry according to PERMEN / LH /
5/2014 that is maximal 5 mg / L and 200 mg / L.

Keywords: Ammonia, COD (Chemical Oxygen Demand), Wastewater, Ammonia
and COD levels.
