Abstract

Air limbah merupakan salah satu sumber pencemaran air yang memiliki satu atau lebih parameter bagi lingkungan yang dapat memberikan dampak negatif berupa gangguan terhadap kesehatan manusia, kehidupan biotik dan keindah. Air limbah memerlukan pengolahan sebelum dialirkan ke lingkungan. Rumah Sakit Bhayangkara memiliki satu unit pengolahan air limbah yang selam ini belum pernah dilakukan pemeriksaan efektifitas dari unit pengolahan limbah cair ini. Penelitian ini menggunakan metode penelitian deskriptif yang mendiskripsikan parameter kualitas air limbah rumah sakit belum dan sesudah dilakukan pengolahan. Sampel diambil pada influent dan effluent selama tujuh hari sebanyak 42 kali masing-masing pada pukul 08.00, 12.00 dan 16.00 WIB Hasil pemeriksaan rata-rata kadar suhu influent 2,17 oC dan effluent 28,15 oC Rata-rata kadar TSS influent 42,14 mg/l dan effluent 2,76 mg/l. Efisiensi Pengolahan TSS 93,45%. Rata-rata kadar pH influent 7,85 dan effluent 7,35. Rata-rata kadar NH4+ influent 23,43 mg/l dan effluent 4,03 mg/l. Efisiensi pengolahan NH4+ 82,80%. Rata-rata kadar BOD5 influent 121,91 mg/l dan effluent 10,62 mg/l. Efisiensi pengolahan BOD5 91,29%. Rata-rata kadar COD effluent 263,78 mg/l dan effluent 24,49 mg/1. Efisiensi pengolahan COD 90,72%. Rata-rata kadar PO4= influent 7,67 mg/l dan effluent 2,32 mg/1. Efisiensi pengolahan PO4= 69,75%. Rata-rata kadar MPN Coliform ifluent 9.166,36 MPN. efisient pengolahan MPN Coliform 51,59%. Hasil pengolahan limbah Cair di Rumah Sakit Byarangkara yang memenuhi baku mutu menurut Peraturan Daerah Propinsi Jawa Tengah No. 10 Tahun 2004 tentang baku mutu limbah cair bagi kegiatan rumah sakit adalah suhu, TSS, pH, BOD5 dan COD kecuali NH4+ dan MPN Coliform. Efektifititas pengolahan limbah cair yang menunjukkan pengolahan efektif adalah TSS, BOD5 dan COD, sedangkan yang Disarankan agar limbah cair sebelum dibuang ke badan air dilakukan proses aerasi untuk menurunkan NH4+ penambahan Ca(OH)2 untuk menurunkan PO4= dan klorinasi dengan dosis yang tepat untuk menurunkan MPN Coliform.

THE EFFECTIVENESS OF WASTE WATER TREATMRNT IN CENTRAL JAVA REGIONAL POLICE' BHAYANGKARA HOSPITAL, SEMARANG Waste water constitues one of many sources of pollutans possesing one environmenral qualitative parameter. Waste waster might impose some negative effects on the environment, human health, biotic life and aesthetics. Therefore, waste water should be treated before being channeled out to the surroundings. Bhayangkara hospital has one unit of waste water treatment, but so far there has not been any done study on the effectiveness of the plant. This study used descriptive method for describing the qualitative paramenters of the Iwaste water of hospital both before and after treatments. The samples taken 42 times, at 8 a.m., 12 a.m. and 4 p.m. everyday for 7 days. The analyses showed the following results. The average temperatures of the influents and the effluents were 28,7 and 28,15 oC. The average TSS contents of the influents and the effluents were 42, 14 and 2,76 mg/1, efficiency value of 93,45 %. The average pH contents of the influents and the effluents were 7,85 and 7,35 The average NH4+ contents of the influents and the effluents were 23,43 and 4,03 mg/1, efficiency value of 82,80 %. The average BOD5 contents of the influents and the effluents were 121,91 and 10,62 mg/1, efficiency value of 91,92 %. The average COD contents of the influents and the effluents were 263,78 and 24,94 mg/1, efficiency value of 90,72 %. The averge PO4= contents of the influents and the effluents were 7,67 and2,32 mg/l, efficiency value of 69,75 %. The average coliforms contents of the influents and the effluents were 18.935,24 and 9.166,36 MPN, efficincy value of 51,59 %. The effluent of the waste water treatments, in Bhayangkara Hospital, that meet the quality standards established by the Regulation Number 10, 2004 of the Cental Java Province were temperatures, TSS, pH, BOD5 and COD, whereas NH4+ and coliforms The waste water treatment showed effectiveness in processing TSS, BOD5 and COD parameters, shereas it processed NH4+ and coliform in lt is recommended that before being disposed to environments, the waste water should be aerated in order to reduce NH4+ Ca(OH)2 should be added to the waste in order to reduce PO4= contens and chlorinization in appropriate dosage should also be conducted in order to reduce the coliforms contents.
