PADA AIR LIMBAH RUMAH SAKIT DENGAN METODE
TITRIMETRI REFLUKS TERTUTUP DI
LABORATORIUM SUCOFINDO
ABSTRAK
Analisa kadar chemical oxygen demand (COD) pada air limbah rumah sakit dengan menggunakan metode titrimetri refluks tertutup. Telah dilakukan pemanasan sampel limbah rumah sakit yang sudah melalui proses pengolaan selama 2 jam pada suhu 148oC didalam COD thermoreactor diperoleh bahwa kadar COD pada air limbah yaitu minggu pertama 52,33mg/L, minggu kedua 63,62mg/L, minggu ketiga 68,42mg/L, minggu keempat 58,43mg/L dan minggu kelima 46,54mg/L. Dari hasil yang diperoleh menunjukkan bahwa air limbah rumah sakit tersebut tidak melebihi standar maksimum yang telah ditetapkan oleh KEP-58/MENLH/12/1995 tentang baku mutu air limbah rumah sakit.

ABSTRACT
Analysis of the levels of chemical oxygen demand (COD) in wastewater hospitals using closed reflux titrimetric method. Has done heating samples of hospital waste that passes through the refineries for 2 hours at a temperature of 148 ° C in COD Thermoreactor obtained that level of COD in waste water that is the first week of 52.33 mg / L, the second week of 63.62 mg / L, the third week 68.42 mg / L, the fourth week of 58.43 mg / L and the fifth week of 46.54 mg / L. From the results obtained show that the hospital waste water does not exceed the maximum standards set by KEP-58 / MENLH / 12/1995 concerning water quality standards of hospital waste.
