Abstract

Meningkatnya perkembangan kegiatan dan pertumbuhan penduduk serta wilayah pemukimanmenyebabkan meningkatnya buangan air limbah.Sungai Sangkub sebagai lokasi penelitianmerupakan Sungai Lintas Provinsi, dimana bagian hulu berada di Provinsi Gorontalo dan hilir diProvinsi Sulawesi Utara.Peningkatan kegiatan ekonomi dan pembangunan dalam rangkameningkatkan kesejahtraan masyarakat menyebabkan terjadinya penurunan kualitas perairanSungai Sangkub. Tujuan penelitian ini adalah untuk menganalisis kualitas air, menentukan statusmutu air serta merumuskan strategi dalam usaha pengendalian pencemaran air Sungai Sangkub diKabupaten Bolaang Mongondow Provinsi Sulawesi Utara.Metode penelitian yang digunakan yaitu bersifat dekriptif dengan pendekatan kuantitatif dankualitatif.Populasi diambil di Sungai Sangkub yang terdiri dari 7 titik penelitian dan 19 parameterkualitas air.Data Primer adalah data series pemantauan kualitas air Sungai Sangkub dari bulan Juli2018 /d Mei 2019 sebanyak 4 kali pemantauan dan observasi lapangan, data sekunder diperoleh dariinstansi terkait. Analisa data dilakukan secara deskriptif.Data disajikan dalam bentuk tabel, gambardan narasi.Analisis data sesuai Peraturan Pemerintah Nomor 82 Tahun 2001 tentang PengelolaanKualitas Air dan Keputusan Menteri Negara Lingkungan Hidup Nomor 115 Tahun 2003 PedomanPenentuan Status Mutu Air serta metodestandart for pratice of conservation (OSPC) denganmengunakan piranti lunak miradi dalam merumuskan strategi pengendalian.Hasil penelitian menunjukkan kualitas air Sungai Sangkub berdasarkan uji parametermenunjukan penurunan kualitas dimana parameter TDS, TSS, Total Fosfat, Total Chlorine, Sulfida,E. Coli dan Total Coliform melebihi baku mutu yang dipersyaratkan dalam PP 82/2001 sedangkanpenentuan status mutu air berdasarkan KepmenLH 115/2003 pada perairan Sungai Sangkub telahmengalami Cemar Berat.Penelitian ini dapat disimpulkan bahwa perairan Sungai Sangkub tercemar berat oleh parameterTDS, TSS, Total Fosfat, Total Chlorine, Sulfida, E. Coli dan Total Coliform. Disarankan untukPemerintah Kabupaten Bolaang Mongondow Utara dan Pemerintah Provinsi Sulawesi Utara dapatmelakukan pengendalian dengan meningkatkan inventarisasi dan identifikasi sumber pencemar air,melakukan pengelolaan limbah, menetapkan daya dukung dan daya tampung, meningkatkan peranserta masyarakat, melakukan pengawasan dan melakukan pemantauan kualitas air sungai secararutin.Kata Kunci : Kualitas Air, Status Mutu, Pengendalian Pencemaran Air Sungai

Abstract

Environment is an importan issue and complex. The rate of population growth and developmentgreatly affects the quality of the environment in Manado City. Environmental quality is an environmentalcondition that can provide optimal carrying capacity for human survival in an area. Environmental qualityincludes water quality, air quality, and land cover quality. This study aims to analyze the EnvironmentalQuality Index in Manado City which includes the Water Quality Index, Air Quality Index, and Land CoverQuality Index.The method used in this research is descriptive quantitative. Measurement of water quality was carriedout in three major rivers in Manado City, namely the Tondano River, the Sario River, and the MalalayangRiver. From each river, measurements of water quality were carried out at two points, including theupstream and downstream areas with the measured parameters TDS, TSS, BOD, COD, and DO. Analysisof water quality using the Pollution Index (PI) method and then converted into the Water Quality Indexvalue. Measurement of air quality were carried out at three points, including office, transportation, andresidential areas with parameters measured as SO2 and NO2. Analysis of air quality using a calculation ofthe European Union (EU) model of Air Quality Index and then converted into an Air Quality Index value.Measurement of land cover quality is carried out by calculating the land cover index, namely measuring thearea of Manado City and the area of green land or forest using ArcGIS Software. The land cover value isobtained from the division between the area of green land or forest and the area of Manado City and thenconverted into the Land Cover Quality Index value. Analysis of Environmental Quality was carried out bycalculating the Environmental Quality Index in Manado City, namely the value of the Water Quality Index(30%), Air Quality Index (30%), and Land Cover Quality Index (40%).The quality of water in Manado City based on the parameter test showed a decrease in quality wherethe parameters of BOD, COD, and DO exceed the quality standards according to PP 82 of 2001 while thestatus of water quality in the mildly polluted category was based on KepMen LH 115 of 2003. The value ofthe Water Quality Index obtained 80. The Quality of Air in Manado City based on the results of monitoring,the highest values of SO2 and NO2 in the transportation area. The value of the Air Quality Index obtained30,56. The Quality of Land Cover in Manado City is based on the calculation of the Land Cover Indexobtained 0,72. The Land Cover Quality Index value obtained 89,60. The results of the EnvironmentalQuality Index value for the City of Manado obtained 69 with the predicate Fairly Good.Based on the results of the study, it can be concluded the Environmental Quality Index in Manado Cityis fairly good. It is recommended for Manado City Goverment in achieving a better environmental conditionneeds to increase activities that are managing and providing protection for the environment in Manado City.Keywords: Environmental Quality Index
