Abstract

Kali Surabaya merupakan salah satu sumber daya air di Provinsi Jawa Timur yang mengalir sepanjang 42,3 Km. Kali Surabaya mempunyai fungsi sosial ekonomi dan budaya yang kental karena fungsinya sebagai sumber air baku air minum, industri, pertanian maupun rekreasi bagi Kabupaten Mojokerto, Sidoarjo, Gresik dan Kota Surabaya. Masalah yang sering terjadi adalah sebagian besar limbah cair dari hasil aktifitas masyarakat dibuang ke saluran yang bermuara di Kali Surabaya. Penelitian ini bertujuan untuk mengetahui sumber pencemar spesifik yang terjadi di Kali Surabaya sehingga dapat ditentukan strategi pengelolaan dalam meminimisasi pencemaran air limbah yang terjadi. Penelitian diawali dengan melakukan pengumpulan data primer berupa plotting sumber pencemar di sepanjang Kali Surabaya dan pengambilan uji kualitas air dengan parameter BOD, COD, TSS dan pH. Selanjutnya data hasil uji kualitas air limbah akan dibandingkan dengan Kepmen LH No.72 Tahun 2013 serta dilakukan perhitungan beban pencemaran. Sebagai tambahan, dilakukan pengumpulan data sekunder kualitas air Kali Surabaya selama 5 tahun dan dilakukan analisis berdasarkan Peraturan Pemerintah No. 82 Tahun 2001 terkait klasifikasi mutu kelas air Kali Surabaya. Hasil penelitian didapatkan, sebanyak 215 titik sumber pencemar berupa saluran air limbah domestik, 10 sumber pencemar berupa outlet effluent industri yang membuang limbah cair nya ke Kali Surabaya. Adanya 225 titik sumber pencemar tersebut menyebabkan kualitas air Kali Surabaya tidak memenuhi baku mutu air kelas I, yaitu kriteria mutu air yang dimanfaatkan sebagai air baku air minum sesuai PP No. 82 Tahun 2001. Strategi pengelolaan pencemaran air Kali ii Surabaya yang dapat diberikan yaitu: (1) pelaksanaan program pembangunan IPAL komunal di wilayah pemukiman; (2) peningkatan frekuensi kegiatan pengawasan untuk wilayah industri; (3) penegakan hukum maupun rewards kepada industri dalam pengelolaan lingkungan. ==================================================================================================== Kali Surabaya is one of the water resources located in East Java, which flows along 42,3 Km from Mojokerto District to Surabaya. Kali Surabaya has a social, economic and cultural functions which is closely related to their use as raw water of drinking water, industrial, agriculture and recreation for Mojokerto, Sidoarjo, Gresik District and also City of Surabaya. The main problem that often occurs in Kali Surabaya is wastewater discharges from daily activities into drains that leads to Kali Surabaya and it’s estuaries. This research aims to determine the source of spesific pollutant contained in Kali Surabaya, to select the management strategy to minimize waste pollution. The research begins by collecting primary data such as plotting pollutant point sources along Kali Surabaya and collection of waste water quality for BOD, COD, TSS and pH. Futhermore, results of waste water quality will be compare with regulation of Kepmen LH 72/2013 and used to make calculation of pollutant load. In addition, collecting secondary data also conducted of water quality Kali Surabaya for 5 years and carried out the analysis of water quality based on regulation Peraturan Pemerintah No. 82/2001. The results show, 215 point sources pollution has found in the form of drains and 10 point sources pollution in the form of industrial which discharge their waste water into Kali Surabaya. The 225 point sources of these pollutants caused the water quality of Kali Surabaya exceeded the water quality standard class 1 which is used as raw water for drinking water based on goverment regulation Peraturan Pemerintah No. 82/2001. Water pollution management strategies for Kali iv Surabaya granted from this research is (1) implementation Waste Water Treatment Plant (WWTP) development program in residential areas; (2) increase frequency of surveillance activities for industrial area; (3) establish law enforcement and rewards to the industry in environmental management.
