Abstract

Surabaya merupakan kota terbesar nomor dua di Indonesia yang terletak di Provinsi Jawa Timur. Status tersebut tidak terlepas dari jumlah penduduk di Kota Surabaya yang terus bertambah. Hal ini juga berimbas terhadap penyediaan fasilitas umum yang memadai oleh Pemerintah Kota Surabaya demi tercapainya kesejahteraan penduduk. Rusunawa merupakan salah satu program dari Pemerintah Kota Surabaya guna meningkatkan kesejahteraan khususnya bagi masyarakat dengan penghasilan rendah (MBR). Pada rusunawa terdapat tangki septik yang menampung air bekas penggunaan hunian, namun nilai efluen dari tangki septik masih melebihi baku mutu. Sehingga sangat berbahaya jika digunakan oleh pengelola rusunawa untuk kegiatan menyiram tanaman. Alternatif yang ditawarkan untuk mengatasi permasalahan tersebut adalah dengan menggunakan teknologi pengolahan air limbah berupa Moving Bed Biofilm Reactor (MBBR) ataupun Anaerobic Baf led Reactor (ABR) . Unit pengolahan MBBR memiliki keunggulan dalam menurunkan kandungan nitrogen. Sementara penggunaan teknologi ABR yang digabung dengan unit ABF hanya membutuhkan sedikit lahan, dapat menangani permasalahan IPAL di Rusunawa Gunung Anyar, dimana efluen IPAL yang masih berada diatas baku mutu. Didapatkan hasil pengolahan menggunakan grease trap, ABR, ABF, multi media filter, dan desinfeksi dibawah baku mutu, dengan nilai TSS = 1,10 mg/L, BOD = 3,07, COD = 4,08 mg/L, dan amonia = 1,54 mg/L. Sehingga air hasil olahan dapat dimanfaatkan untuk kegiatan perairan lahan.

Surabaya is the second largest city in Indonesia, located in East Java Province. This status cannot be separated from the population in the city of Surabaya which continues to increase. This also has an impact on the provision of adequate public facilities by the Surabaya City Government to achieve the welfare of the population. Rusunawa is one of the programs of the Surabaya City Government to improve welfare, especially for people with low incomes (MBR). In flats there is a septic tank that collects water used for residential use, but the effluent value from the septic tank still exceeds the quality standard. So it is very dangerous if it is used by flat managers for watering plants. The alternative offered to overcome this problem is to use wastewater treatment technology in the form of a Moving Bed Biofilm Reactor (MBBR) or Anaerobic Baffled Reactor (ABR). The MBBR processing unit has the advantage of reducing nitrogen content. Meanwhile, the use of ABR technology combined with an ABF unit only requires a small amount of land, and can handle the IPAL problem in Rusunawa Gunung Anyar, where the IPAL effluent is still above quality standards. Obtained processing results using grease traps, ABR, ABF, multi media filters, and disinfection below quality standards, with values of TSS = 1.10 mg/L, BOD = 3.07, COD = 4.08 mg/L, and ammonia = 1.54 mg/L. So that the processed water can be used for land water activities.
