Abstract

The chrome metal coating industry can produce toxic waste, and if it is disposed of freely, it will cause severe contamination of soil and water. Chrome metal pollution needs to be minimized, considering the impact caused besides polluting the environment also disrupts human health and other living things. Measures to reduce or even eliminate these hazards by treating waste before being discharged into free water. Wastewater technology that contains heavy metals can be reduced using bioremediation. Research has been carried out on samples of metal coating industry wastewater containing heavy metal chromium with 2.5161 ppm on initial levels. Bacillus subtilis bacteria with various concentrations with unit cells/ml (102.5 and 105) were added to the samples and stored for two days. Chromatic metal levels after bioremediation were measured by spectrophotometry. Bioremediation with Bacillus subtilis can reduce chromium metal content by 91.33% and 80.24% at concentrations of 102.5 and 105. Bacillus subtilis were 102.5 cells/ml lower chromium metal levels higher than that of Bacillus subtilis 105 cells/ml. REFERENCES
