Abstract

Rumah Sakit Islam Surakarta (RSIS) merupakan rumah sakit type C dan mempunyai kapasitas tempat tidur 150 buah, dengan rata-rata BOR 62,14% (september 2005). (IPLC ) yang mengola limbah cair sebanyak 70,33 m3/hr. Adapun dampak amoniak terhadap kesehatan karena dapat bereaksi dengan hemoglobine dalam darah, sehingga darah tersebut tidak dapat mengangkut oksigen lagi. Kadar ammoniak yang ada dikolam indikator IPLC RSIS adalah 0,85 mg/lt, tahun 2005 belum memenuhi standar Peraturan Daerah Propoinsi Jawa Tengah Nomor 10 Tahun 2004, Khususnya kadar amoniak, adalah 0,1 mg/lt. Tujuan penelitian ini adalah untuk mengetahui pengaruh berbagai lama komtak aerasi model payung pada kolam indikator terhadap penurunan kadar amoniak (NH3) limbah cair RSIS, mengukur kadar amoniak (NH3) inlet, sebelum dan sesudah aerasi model payung, mengetahui perbedaan kadar amoniak (NH3). Jenis penelitian adalah ekperimen semu, pengolahan data menggunakan uji t,uji anov dan uji LSD. Hasil penelitian dari pengukuran kadar amoniak sebelum dan sesudah aerasi model payung mengalami penurunan adalah lama kontak 12 jam dengan kadar amoniak 0,07 mg/lt, perbedaan kadar amoniak (NH3) sebelum adalah 0,72 mg/lt dan sesudah aerasi model payung adalah 0,07 mg/lt. Perbedaan kadar amoniak limbah cair Rumah Sakit Islam Surakarta adalah 12 jam sebesar 23,4%. Adapun pengaruh berbagai lama kontak aerasi model payung pada kolam indikator terhadapa penurunan limbah cair RSIS dengan kadar amoniak minimum 0,07 mg/lt dan maksimim 0,64 mg/lt. Bagi pengelola IPLC khususnya operator IPLC hendaknya dilakukan pemambahan lam kontak dari 10 menjadi 12 jam. Kata Kunci: Limbah cair,Aerasi Model Payung, Kadar Surakarta Islamic Hospital (RSIS) is tyte C hospital and have bed capacities 150, with BOR average is 62,14% (September 2005). Surakarta Islamic Hospital have a Liquid Waste Processing Installation (IPLC) which managing liquid waste counted 70,33 m3/day. As for ammonia impact to health, because it can reacting with haemoglobin in blood, so that blood can not transporting oxygen again. Ammonia rate which in indicator poolof IPLC in RSIS is 0,85 mg/lt, in 2005 not yet fulfilled standard by Law of Province Central Java Number 10 Year 2004, specially ammonia rate, is 0,1 mg/lt. This research target is to knows influence of various duration aeration contact with umbrella model at indicator pool to degradation of ammonia rate (NH3)of liquid waste in RSIS, measuning ammonia rate (NH3) inlet, before and affter umbrella model aeration, knowing difference of ammonia rate between duration aeration contact with umbrella model which most optimal, and to analyze difference of umbrella model aeration todegradation ofammonia rate (NH3). Type of the research is quasi-experimental, data processing use t-test, anova test and LSD test. Research result of measurement of ammonia rate before and after umbrella model aerastion which experience degradation is contact duration 12 hours with ammonia rate 0,07 mg/lt, difference of ammonia rate (NH3) before aeration is 0,72 mg/lt and after model umrella aeration is 0.07mg/lt. Defference of ammonia rate (NH3) between most aptimal contact duration to degradation of ammonia rate of liquid waste in Surakarta Islamic Hospital is 12 hours equal to 23,4%.As for influence various duration aeration contact with umbrella model at indicator pool to degradation of liquid waste in RSIS with minimum ammonia rate 0,07 mg/lt and maximum 0,64 mg/lt. For manager of IPLC, especially of IPLC operator shall make addition of contact duration from 10 hours become hours. Keyword : AmoniakLiquid Waste,Umbrella Model Aeration,Ammonia Rate
