Penggunaan Teknologi Gelembung Mikro Nano Ozon Dalam Penurunan Kadar NH3 pada Limbah Cair Rumah Sakit (Studi Pada Limbah Cair Rumah Sakit X Kabupaten Banyuwangi)

Abstract

Hospital waste water comes from hospital activities which can cause environmental pollution, be a source of disease and result in health problems, so it needs to be processed through a Waste Water Treatment Plant (IPAL). The ozonation process is effective in optimizing waste processing because it does not produce pollutants in the water so it can be categorized as an environmentally friendly process. So this study aims to analyze the reduction in NH3 levels in the control group and treatment groups for 10, 30 and 60 minutes. This research is a type of True Experiment research or a real experiment with a Posttest Only Control Group Design. The total number of replications or repetitions was 6 times in 4 treatments so that the total number of samples was 24 samples. the total waste water required is 360 liters. statistical analysis with the normality test, followed by the Kruskall Wallis test. The results of this study were in repetition 1 with sample sequences (X0), (X1), (X2), and (X3) 2.64 mg/L, 0.0007 mg/L, 0.0089 mg/L and 0, 0239 mg/L. In repetition 2 the results were 3.186 mg/L, 0.0327 mg/L, 0.0082 mg/L and 0.0087mg/L. At repetition 3 it was 2.644 mg/L, 0.0074 mg/L, 0.0038 mg/L, and 0.0347. At repetition 4 1.38 mg/L, 0.018 mg/L, 0.0383 mg/L and 0.025. At repetition 5 it was 4.709 mg/L, 1.7354 mg/L, 1.48 mg/L and 2.108 mg/L. At repetition 6 it was 7.075 mg/L, 2.504 mg/L, 1.8674 mg/L, and 2.136 mg/L. average NH3 levels at (X0) 3.605 mg/L, (X1) 0.7163 mg/L, (X2) 0.5677 mg/L, (X3) 0.7227 mg/L. The Kruskall Wallis test result is 0.015. The results of this study can be concluded that there is a difference in the average NH3 levels in the control group and the ozone micro-nano bubble treatment group.
