Analysis of the Quality of Hospital Waste in Bengkulu City

Abstract

Hospital wastewater can contain pathogenic microorganisms and harmful chemicals that could affect the environment and the organism around. Testing the quality of wastewater is necessary to determine the level of pathogenic microorganisms or organic and inorganic compounds by testing with physics, chemistry, and biologcal parameters. These tests are performed to identify the quality of wastewater and the factors that influence it, as well as to know the techniques and parameters used in the quality analysis of wastewater. The quality analysis of wastewater using three test of parameters, which include temperature test and TSS (Total Suspended Solid) wich contitudes the physics parameter (14 mg/L), an inorganic chemical parameter that consist the test of Ph (7.51), iron (Fe)(0.018 mg/L), manganese (Mn)(0.013 mg/L), copper (Cu) (2 mg/L), nitrite (NO2) (0.008 mg/L), sulfide (S 2-) (0.005 mg/L), BOD (Biochemical Oxygen Demand) (25 mg/L), COD (Chemical Oxygen Demand) (55 mg/L), oils and fats, MBAS (Methylene Blue Active Surfactant) (0.306 mg/L), ammonia (NH3-N) (0.860 mg/L), and the microbiology parameter which is total coliform test (2940 MPN/100 ml). These tests are performed according to Indonesian national standards (SNI) and work instructions of environmental laboratory (IK LL). Result from the test showed that quality value of the wastewater analysis does not exceed the quality standards from PERMEN LH NO 5 TH 2014 and PERMEN LH RI No. P.68/Menlhk-Setjen/2016. Based on the result showed that the intalation of wastewater treatment work properly according to the quality standard from the government.
