Rumah Sakit merupakan salah satu sarana pelayanan kesehatan masyarakat yang di dalamnya berlangsung aktivitas-aktivitas medis dan non medis. Keputusan Menteri Negara Lingkunangan Hidup No. KEP-58/MENLH/12/1995 tentang kegiatan Rumah Sakit yang mempunyai potensi menghasilkan limbah yang dapat menimbulkan pencemaran lingkungann perlu melakukan pengendalian terhadap pembuangan limbah cair yang dibuang ke lingkungan sehingga dapat memenuhi Baku Mutu Limbah Cair Bagi kegiatan Rumah Sakit. Tujuan dalam tugas akhir ini adalah menurunkan konsentrasi BOD5, NH3, COD dan TSS agar memenuhi standar Baku Mutu Limbah Cair, perlu dilakukan perbaikan terhadap kinerja proses IPAL (Instalasi Pengolahan Air Limbah) Rumah Sakit Santo Yusup.

Rangkaian sistem pengolahan air limbah di RSSY terdiri dari bar screen, bak equalisasi, bak clarifier, bak buffer, FBC- Bioreaktor (biodetox), bak khlorinasi, bak polishing dan Treated Water Tank. Pengolahan air limbah dari kegiatan medis dan non medis RSSY dimaksudkan untuk mengurangi pencemaran saat dibuang ke lingkungan sehingga memenuhi Baku Mutu Limbah Cair (BMLC) bagi kegiatan Rumah Sakit yaitu No.58/MENLH/10/1995. Berdasarkan hasil evaluasi melalui kegiatan sampling, pengukuran dan perhitungan, makan diketahui bahwa permasalahan terjadi pada unit Clarifier dan Unit FBC Bioreaktor. Pada unit Clarifier parameter TSS tidak dapat diturunkan dengan kondisi Inlet 361,7 mg/lt dan Outlet 261,7 mg/lt, maka efisiensi eksisting 0%. Berdasarkan hasil pengukuran nilai effluent unit FBC Bioreaktor diperoleh nilai BOD5 = 164,8

mg/lt, NH3 sebesar 0,35 mg/lt, dan COD sebesar 625 mg/lt. Kinerja dari unit biodetox untuk menyisihkan parameter N-Amoniak (NH3) tidak berlangsung dengan baik, maka dilakukan penambahan nutrisi

Hasil evaluasi pemeriksaan BOD5, TSS, COD dan NH3 perlu dilakukan perbaikan unit. Hasil Perbaikan pada unit Clarifier dan FBC Bioreaktor biodetox. Pada unit Clarifier dengan perubahan lebar menjadi 1m, FBC Bioreaktor biodetox dengan menambahkan media filter, dan penambahan 1 unit FBC - Bioreaktor biodetox. Berdasarkan hasil perhitungan untuk meningkatkan kandungan unsur N diperlukan pupuk Urea sebesar 2,618 kg/hari dengan harga Rp. 4700/kg, dan untuk meningkatkan unsur P diperlukan pupuk TSP sebesar 0,997 kg/hari dengan harga Rp. 7500/kg. Biaya yang diperlukan untuk perbaikan unit Rp. 16.536.125,- dan dibutuhkan biaya nutrisi Rp. 32.058,-/hari.

Hospital represent one of the medium service of health of society which in it take place medical activities and non is medical. Decree Of The State'S Minister of Enviromental Live No. KEP-58/MENLH/12/1995 about activity of Hospital having potency yield waste able to generate contamination of enviromental require to conduct operation to dismissal of thrown liquid waste to environment so that can fulfill Standard Quality of Liquid Waste To activity of Hospital. Target of in this final duty is to degrade concentration of BODS, NH3, COD and of TSS to be fulfilling Standard standard Quality of Liquid Waste, require to be conducted by repair to performance process IPAL (Installation Processing Of Water Waste) Hospital of Santo Yusup.

System network processing of waste water in RSSY consist of bar of screen, basin of equalitation, basin of clarifier, basin of buffer, FBC - Bioreactor (Biodetox), basin of chlorination, basin of polishing and of Treated Water Tank. Processing of waste water of medical activity and non is medical of RSSY meant for the less of contamination of moment thrown to environment so that fulfill Standard Quality of Liquid Waste (BMLC) to activity of Hospital that is No.58/Menlh/10/1995.

Pursuant to result of evaluation through activity of sampling, calculation and measurement, eat to be known that problems happened at unit of Clarifier and Unit of FBC Bioreactor. at unit of Clarifier parameter of TSS cannot be degraded with condition of Inlet 361,7 mg / and it of Outlet 261,7 mg / lt, hence efficiency of existing 0%. Pursuant to result of measurement of value of effluent unit of FBC - Bioreactor obtained by value of BODs equal to 164,8 mg / 1t, NH3 equal to 0,35 mg / It, and COD equal to 625 mg / /1t. Performance of hance of unit of Biodetox to cast aside parameter of N-Ammoniac (NH3) do not take place better, hence conducted by addition of nutrition.

Result of evaluation inspection of BOD5, TSS, COD and of NH3 require to be conducted by repair of unit. Result of Repair at unit of Clarify and of FBC - Bioreactor Biodetox. At unit of Clarifier with wide change become 1m, FBC - Bioreactor Biodetox by enhancing media of filter, and addition 1 unit of FBC - Bioreactor Biodetox. Pursuant to result of calculation to increase element content of N needed by manure of Urea equal to 2,618 kg/day at the price of Rp. 4700/ kg, and to increase element of P needed by manure of TSP equal to 0,997 kg/day at the price of Rp. 7500/ kg. Expense of needed to repair of unit of Rp. 16.536.125,- and required by the expense of Rp nutrition. 32.058,-/day
