EFEKTIVITAS INSTALASI PENGOLAHAN AIR LIMBAH BERDASARKAN PARAMETER BIOLOGICAL OXYGEN DEMAND, CHEMICAL OXYGEN DEMAND DAN DERAJAT KEASAMAN DI RUMAH SAKIT UMUMGMIM PANCARAN KASIH MANADO
Abstract
Limbah cair di rumah sakit dapat mengandung bahan organic dan anorganik yang umumnya diukur dengan parameter. Parameter yang digunakan dalam menentukan kualitas limbah cair yaitu parameter fisik, kimia dan mikrobiologi. Parameter berupa Total Solid (TS), Total Solid Suspended (TSS), warna, kekeruhan dan bau. Parameter kimia berupa Oxygen Demand (OD), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen Demand dan derajat keasaman (pH) sedangkan parameter biologi yang diperiksa adalah Coliform. Tujuan dalam penelitian ini ialah mengetahui efektivitas instalasi pengolahan air limbah berdasarkan parameter BOD, COD dan pH di RSU GMIM Pancaran Kasih Manado. Penelitian ini adalah survei deskriptif berbasis uji laboratorium. Penelitian ini dilakukan di RSU GMIM Pancaran Kasih Manado pada bulan Agustus 2019. Untuk parameter BOD menggunakan metode inkubasi, COD menggunakan metode refluks dan pH menggunakan metode elektrometri. Data hasil pengujian atau analisis BOD, COD dan pH di bandingkan dengan baku mutu/standar yang sesuai dengan standar baku mutu Peraturan Menteri Lingkungan Hidup Republik Indonesia Nomor 5 Tahun 2014 tentang Baku Mutu Air Limbah. Hasil penelitian menunjukkan efektivitas IPAL terhadap BOD yaitu sangat efektif, COD efektif dan pada pH tidak efektif. Kandungan BOD, COD dan pH tidak melewati baku mutu yang ditetapkan untuk limbah Rumah Sakit.
Kata Kunci: BOD, COD, pH, Limbah Cair.
ABSTRACT
Liquid waste in hospitals can contain organic and inorganic materials which are generally measured by parameters. The parameters used in determining the quality of liquid waste are physical, chemical and microbiological parameters. The parameters are Total Solid (TS), Total Solid Suspended (TSS), color, turbidity and odor. Chemical parameters in the form of Oxygen Demand (OD), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen Demand and acidity (pH) while the biological parameters examined are Coliform. The purpose of this study was to determine the effectiveness of wastewater treatment plants based on BOD, COD and pH parameters at GMIM Pancaran Kasih Manado Hospital. This research is a descriptive survey based on laboratory tests. This research was conducted at GMIM Pancaran Kasih Manado Hospital in August 2019. For BOD parameters using the incubation method, COD uses the reflux method and the pH uses the electrometry method. The results of testing or analysis of BOD, COD and pH are compared with the quality standards / standards that are in accordance with the quality standards of the Regulation of the Minister of Environment of the Republic of Indonesia Number 5 of 2014 concerning Wastewater Quality Standards. The results showed that the effectiveness of WWTP on BOD was very effective, COD was effective and at pH not effective. The content of BOD, COD and pH does not exceed the quality standards set for hospital waste
Keywords: BOD, COD, pH, Waste Water.
