Abstract: | Perkembangan bakteri patogen Escherichia coli dapat menyebabkan
penurunan kualitas perairan apabila memiliki populasi yang melebihi baku mutu.
Jumlah bakteri E. coli dapat dikendalikan dengan menggunakan probiotik
komersial yang mengandung bakteri Streptomyces. Penelitian ini bertujuan untuk
menentukan dosis probiotik yang efisien untuk mengendalikan jumlah populasi
bakteri E. coli di dalam air tawar. Probiotik didapat dari produk komersial yang
beredar di pasar dan air uji diperoleh dari Situ Gede, Kabupaten Bogor. Probiotik
dimasukkan kedalam air dengan dosis 0,1 ppm, 0,5 ppm dan 1,0 ppm dan kontrol,
dengan desain penelitian menggunakan rancangan acak lengkap yang masing masing diulang sebanyak tiga kali. Pengamatan pertumbuhan bakteri berupa Total
Plate Count (TPC), diamati sebelum perlakuan dan setiap 12 jam setelah perlakuan.
Parameter kualitas air sebagai penunjang meliputi parameter suhu, oksigen terlarut
dan pH. Hasil pengamatan yang dilakukan selama 36 jam menunjukkan bahwa
dosis 0,5 ppm merupakan dosis yang paling signifikan dalam menekan
pertumbuhan populasi E. coli. The growth of E. coli pathogenic bacteria can lead to decrease the quality of the waters if it has a population that exceeds the quality standard. The amount of E. coli bacteria can be controlled by using commercial probiotics contained Streptomyces bacteria. The study aims to determine efficient doses of probiotics to control the number of populations of E. coli bacteria in freshwater. Probiotics are obtained from commercial products circulated on the market and test water is obtained from Situ Gede, Bogor Regency. In one liter of test water was inserted probiotics with doses of 0.1 ppm, 0.5 ppm and 1.0 ppm and control, with the research design using RAL which was repeated three times each. Observation of bacterial growth in the form of Total Plate Count (TPC), observed before treatment and every 12 hours after treatment. Water quality parameters as supporting which include temperature parameters, dissolved oxygen and pH. Observations made over 36 hours showed that a dose of 0.5 ppm was the most significant dose of suppressing E. coli population growth |
