Abstract

Sungai Banjir Kanal Barat dan Silandak merupakan sungai besar yang berada di Kota Semarang. Terdapat berbagai aktivitas di sepanjang aliran sungai tersebut, diantaranya aktivitas domestik dan industri dimana buangan limbah masuk ke dalam badan sungai sehingga menyebabkan penurunan kualitas perairan. Salah satu mikroorganisme yang terkandung dalam limbah domestik yang berperan sebagai indikator pencemaran yaitu bakteri coliform sehingga perlu dilakukan perhitungan total coliform guna mengetahui adanya pencemaran di Sungai Banjir Kanal Barat dan Silandak. Tujuan dari penelitian ini adalah untuk mengetahui kelimpahan total coliform, status mutu air berdasarkan PP Nomor 82 Tahun 2001 kelas II dan hubungan antara total coliform dengan bahan organik dan BOD (Biological Oxygen Demand) di Sungai Banjir Kanal Barat dan Silandak. Metode yang digunakan dalam penelitian ini yaitu metode survei. Pengambilan sampel terdiri dari 2 stasiun (A dan B) yang masing-masing terdapat 5 titik dan 2 kali pengulangan (P1 dan P2). Variabel utama yang dianalisis yaitu total coliform, bahan organik dan BOD, variabel pendukung yang diukur yaitu temperatur, salinitas, DO (Dissolved Oxygen ) dan pH. Berdasarkan hasil penelitian, jumlah total coliform pada stasiun A berkisar antara 240-16000 MPN/100 mldan 23-5400 MPN/100 ml pada stasiun B. Nilai total coliform pada titik A2 dan B2 pada P1 serta A5 P2telah melebihi bakumutu. Hubungan antara total coliform dengan bahan organik yaitu sangat lemah (nilaiPearson Correlation = 0,15). Hubungan antara total coliform denganBOD yaitu lemah (nilaiPearson Correlation= 0,378). Banjir Kanal Barat and Silandak Rivers are large rivers in Semarang. There are various activities along the river flow, including domestic activities and industries where waste effluents enter the river bodies causing a decrease in water quality. One of the microorganisms contained in domestic waste that as an indicator of pollution is coliform bacteria, so it is necessary to calculate the total coliform in order to find out the pollution in the Banjir Kanal Barat and Silandak Rivers. This study aims to determine abundance of total Coliform, water quality status based on PP No. 82 of 2001 class II and relationship between the total coliform with organic matter and BOD (Biological Oxygen Demand) in the Banjir Kanal Barat and Silandak Rivers. The method used in this study is survey method. Sampling consisted of 2 stations (A and B), each of which had 5  points and 2 repetitions (P1 and P2). The main variables analyzed were total coliform, organic matter and BOD, the supporting variable analiyzed were temperature, salinity, DO (Dissolved Oxygen ) and pH. Based on the results of the study, the total number of coliform at station A ranged from 240-16000 MPN/100 ml and 23-5400MPN/100 ml at station B. The total value of coliform at points A2 and B2 at P1 and A5 P2 has exceeded the standard. The relationship between total coliform and organic matter is very weak (Pearson Correlation value = 0.15). The relationship between total coliform and BOD is weak (Pearson Correlation value = 0.378).

Abstract

Land use around the river, can affect the condition water quality of waters. The purpose of this study are to determine the pollution index and the rate of river sedimentation, and land use around the Banjir Kanal Barat and Silandak River. The method for sampling was purposive sampling. Sampling was carried out in the Banjir Kanal Barat and Silandak River, each of which had 5 points and 2 repetitions (P1 and P2). The variables analyzed were TSS, BOD, COD, total coliform where analyzed with Indonesian Standard National (SNI); DO, pH, temperature, discharge of water analyzed with Water Quality Checker (WQC), Buchanan method used to analyzed sedimentation rate, and sediment fraction. The results of the study, showed that IP in the Banjir Kanal Barat River obtained an IP value of 4.13 (lightly polluted), while the Silandak River obtained an IP value of 4.69 (lightly polluted). The highest sedimentation rate in the Banjir Kanal Barat River with a value of 35.64 tons / day, while the Silandak River has the highest value of 55.81 tons / day. Sediment fraction in Banjir Kanal Barat River is dominated by clay, and Silandak River it is dominated by clay. Land cover in Banjir Kanal Barat river are 3% industry, 85% settlement, 0% water and 12% vegetation, and Silandak River are 7% industry, 69% settlement, 5% water and 7% vegetation.
