Abstrak

Pulau Pasaran merupakan satu-satunya pulau yang ada di wilayah Kota Bandar Lampung. Lokasi Pulau Pasaran cukup dekat dengan muara Sungai Way Belau sehingga limbah domestik dan limbah industri yang berasal dari pusat kota masuk ke perairan sekitar Pulau Pasaran melalui aliran sungai ini. Dengan melihat kondisi tersebut, maka dilakukan kajian terkait status perairan Pulau Pasaran. Tujuan penelitian ini adalah untuk menganalisis beban pencemar, kapasitas asimilasi dan status pencemaran perairan di Pulau Pasaran. Penelitian ini dilaksanakan pada bulan Mei-Juli 2017, pengamatan dan pengambilan data dilakukan pada 5 titik yang ada di sekitar perairan Pulau Pasaran. Parameter kualitas air yang diukur antara lain suhu, salinitas, pH, DO, BOD, COD, NO3, NH3, PO4, TOM, TSS. Analisis data yang dilakukan yaitu perhitungan nilai beban pencemaran menggunakan persamaan Mitsch and Goesselink, perhitungan nilai kapasitas asimilasi menggunakan persamaan regresi linier dan penentuan status perairan menggunakan metode STORET. Hasil analisis perhitungan beban pencemar diperoleh nilai beban tertinggi berasal dari parameter COD baik di sungai atau muara sungai dengan nilai 8192, 92 kg/thn dan 5994.13 kg/thn. Hasil analisis kapasitas asimilasi menunjukan bahwa nilai parameter BOD telah melebihi kapasitas asimilasi perairan Pulau Pasaran. Dan hasil analisis status pencemaran menunjukan perairan Pulau Pasaran tercemar sedang. Kata kunci: Beban Pencemar, Kapasitas Asimilasi, Limbah, Pulau Pasaran,Status Perairan Analysis of Pollutant Load and Assimilation Capacity of Pasaran Island Waters in Lampung Province Pasaran Island is the only island in Bandar Lampung. The location of Pasaran Island is quite close to the Way Belau River estuary so that domestic waste and industrial waste from the city enter the waters around Pasaran Island through this river flow. By looking at these conditions, a study was conducted regarding the status of the waters of Pasaran Island. The purpose of this study was to analyze the pollutant load, assimilation capacity and water pollution status on Pasaran Island. This research was carried out in May-July 2017, observations and data collection were carried out at 5 points around the waters of Pasaran Island. Water quality parameters measured include temperature, salinity, pH, DO, BOD, COD, NO3, NH3, PO4, TOM, TSS. The data analysis was done by calculating the pollution load value using the Mitsch and Goesselink equation, the calculation of the assimilation capacity value using a linear regression equation and determining the status of the waters using the STORET method. The results of the analysis of pollutant load calculations obtained the highest load values derived from COD parameters both in rivers or river estuaries with a value of 8192, 92 kg/yr and 5994.13 kg /yr. The results of assimilation capacity analysis show that the BOD parameter values have exceeded the assimilation capacity of Pasaran Island waters. And the results of the analysis of pollution status showed that the waters of Pasaran Island were moderately polluted. Keywords: Pollution Load, Assimilation Capacity, Pasaran Island, Waste,Water Status
