Noting effluent from factories and soy sauce. A cloudy appearance due to a soluble protein in the form of colloidal substances. This experiment is a test for the ability of lactic acid bacteria (Lactic Acid Bacteria) in the treatment of wastewater to water quality by finding the DO (Dissolved Oxygen) or the amount of dissolved oxygen and PH value is appropriate. By the lactic bacteria from fermented milk with natural methods. Experiment with soy sauce wastewater volume 200, 250, and 300 ml, respectively. Lactic bacteria cells per 25 grams per liter in volume. And the results showed that, after the lactic acid bacteria into the three tubes of protein in waste water from settling on the second day onwards until the measurement DO from 1.10 ppm. This was below 3 ppm. Classified as waste water is high. More than 3 ppm. Classified as water and PH value from 5.7 to 4.44 proteins in sewage sedimentation water is clear
, therefore, conclude that the lactic acid bacteria (Lactic Acid Bacteria) can be septic. The protein in the form of colloidal substances contaminate the water. The clumping Water and silt, making such a valuable DO sufficient to clear up the animal shelter and the water PH at 4:44 of proteins in sewage sedimentation.
