Analisis Kadar Amonia dan COD (Chemical Oxygen Demand) dari beberapa Air Limbah Inlet dan Outlet Pabrik Karet.

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.
