Abstract
Laporan Kinerja Pemerintah Kota Surabaya Tahun 2014 menyatakan bahwa hanya 60% rumah sakit di Surabaya yang sudah mengolah air limbahnya, masih ada beberapa efluen air limbah dari rumah sakit yang belum memenuhi baku mutu dalam Peraturan Gubernur Jawa Timur No. 72 Tahun 2013. Contohnya hasil analisa efluen sebuah rumah sakit kelas C masih belum memenuhi baku mutu yang ditetapkan dalam Peraturan Gubernur Jawa Timur No. 72 Tahun 2013 dan pengolahan air limbah pada rumah sakit kelas tersebut belum dipisahkan antara air limbah non medis dan air limbah medis. Pengolahan air limbah medis dan non medis sebaiknya dipisahkan, karena air limbah nonmedis bersifat non-toksik sedangkan air limbah medis bersifat toksik. Oleh karena itu, diperlukan pengolahan air limbah khusus untuk air limbah non medis. Rencana desain IPAL terbagi dalam dua alternatif, yaitu alternatif pertama menggunakan Anaerobic Filter – bak aerasi dan alternatif kedua menggunakan kombinasi biofilter anaerobik – aerobik. Alternatif pertama ini dipilih karena memiliki tingkat penyisihan padatan terlarut dan nutrien yang tinggi. Alternatif kedua dipilih dikarenakan proses kombinasi anaerobik dan aerobik memiliki nilai penyisihan komponen pencemar yang paling tinggi. Perencanaan ini diawali dengan pengumpulan data primer dan data sekunder. Data primer yang digunakan adalah debit air limbah nonmedis sebuah rumah sakit kelas C dan sampel air limbah nonmedis rumah sakit kelas C. Data sekunder yang digunakan adalah Harga Satuan Pokok Kegiatan Kota Surabaya Tahun 2016, data okupansi, kapasitas, dan fasilitas rumah sakit kelas C di Surabaya. Lalu dilakukan pengolahan data berupa perhitungan dimensi untuk masing-masing unit dalam dua alternatif IPAL, serta membuat Detailed Engineering Design (DED), Bill Of Quantity (BOQ), dan Rancangan Anggaran Biaya (RAB). Setelah itu dibandingkan alternatif mana yang cocok untuk rumah sakit kelas C. Hasil Perhitungan dari alternatif IPAL I, didapatkan unit bak ekualisasi sebanyak 1 buah, tangki septik sebanyak 1 buah, Anaerobic Filter 4 kompartemen, bak aerasi 1 buah, clarifier 1 buah, filtrasi 1 buah, desinfeksi 1 buah. Hasil Perhitungan dari alternatif IPAL II, didapatkan unit bak ekualisasi sebanyak 1 buah, tangki septik sebanyak 1 buah, biofilter anaerobik 4 kompartemen, biofilter aerobik 4 kompartemen, bak pengendap akhir 1 buah, filtrasi 1 buah, filtrasi 1 buah, desinfeksi 1 buah. IPAL I memiliki keunggulan dalam segi volume, luas lahan, efisiensi penyisihan kandungan pencemar, dan efluen air limbah disbanding IPAL II. Oleh karena itu disimpulkan bahwa unit IPAL I lebih cocok digunakan untuk rumah sakit kelas C. RAB untuk IPAL I sebesar Rp 293.997.988 dan IPAL II sebesar Rp 448.863.392.
=============================================================================================================================
Government’s Performance Report of Surabaya City in 2014 stated that only 60% of hospitals in Surabaya has already processed their waste water, but some of those hospitals’ effluent is still remained to be unfulfilled the quality standard by the Regulation of East Java’s Governor number 72 in 2013. For example, the analysis result of effluent produced by C class hospitals still couldn’t pass the quality standard in the Regulation of East Java’s Governor number 72 in 2013 and there haven’t been a separation between non medical and medical waste in the process. There should be a separation between the medical and non medical waste water process because character of non medical waste water is non toxic meanwhile the medical waste water is toxic. Therefore, specific nonmedic wastewater treatment is needed. The design of IPAL that meant to be designed is divided in two alternatives, the first by using Anaerobic Filter – aeration basin and the second by using biofilter combination of anaerobic-aerobic. The first alternative uses Anaerobic Filter – aeration basin is chosen because it has a high dissolved solid and nutrient removal rate.The second alternative uses bio-filter combination of biofilter anaerobic-aerobic is chosen because the process of combinations by anaerobic and aerobic has the highest pollution component removal rate.
This design is started by gathering primary data and secondary data. Primary data that used in this design is C class hospital nonmedical wastewater debit and characteristic. Secondary data that used in this design is activities principal unit price Surabaya City 2016, C class hospital occupancy, capacity, and facilities data in Surabaya. And then, process the data into calculation of dimention for each units in two wastewater alternatives, also create Detailed Engineering Design (DED), Bill of Quantity (BOQ), Cost Budget Plan. After that, the two alternatives have to be compared to get the alternative that can be used in C class hospitals.
The calculation result from IPAL I alternative is 1 unit of equalization tank, 1 unit of septic tank, 4 compartments of Anaerobic Filter, 1 unit of aeration basin, 1 unit of clarifier, 1 unit of filtration, and 1 unit of disinfection. The calculation result from IPAL II alternative is 1 unit of equalization tank, 1 unit of septic tank, 4 compartments of Anaerobic Filter, 4 compartments of aerobic filter, 1 unit of filtration, and 1 unit of disinfection. IPAL I has more advantage in volume, area, removal efficiency, and wastewater effluent compared to IPAL II, therefore it is to be concluded that IPAL I is suitable for C class hospital. The cost for IPAL I is Rp 293.997.988 and for IPAL II is Rp 448.863.392.
