Abstract

Bakteriofag merupakan virus yang dapat menginfeksi dan membunuh sel bakteri secara langsung. Bakteriofag atau fag merupakan parasit obligat intraseluler yang berkembang biak pada sel bakteri sebagai inangnya dan dapat digunakan sebagai biokontrol dari bakteri. Tujuan dilakukannya penelitian ini adalah untuk mengetahui efektivitas dengan metode plaque assay bakteriofag yang mampu menginfeksi bakteri P. aeruginosa dari air kolam rumah burung walet di Kalimantan Selatan. Metode penelitian yang dilakukan yaitu pembuatan media yang terdiri dari media Nutrient Agar (NA), media soft agar dan media double layer. Sampel yang digunakan pada penelitian ini terdapat satu sampel yang berasal dari air kolam rumah burung walet yang di uji pada bakteri P. aeruginosa. Uji plaque assay dimulai dengan pembuatan dilution atau pengenceran. Setiap pengenceran di ambil sebanyak 500 μL, kemudian diinokulasikan pada media soft agar yang berisi 100 μL kultur bakteri lalu dihomogenkan, setelah itu dituangkan pada cawan petri yang telah berisi media NA. Kemudian diinkubasi selama 24 jam pada suhu 28°C. Hasil plaque assay bakteriofag pada sampel air kolam terdapat tiga pengenceran yang menunjukan hasil positif terhadap P. aeruginosa dengan tipe plak clear dan tipe plak turbit. Jumlah plak yang terbentuk termasuk jumlah plak yang memenuhi syarat yaitu sekitar 25-250. Setelah diketahui jumlah plak yang terbentuk maka dilakukan dengan perhitungan titer bakteriofag yang menggunakan satuan Plaque From Units (PFU/ml). Pada perhitungan titer bakteriofag didapatkan hasil 5,1x107 PFU/mL dan termasuk konsentrasi titer bakteriofag yang rendah. Kata kunci : Bakteriofag, Rumah burung walet, P. aeruginosa, plaque assay Bacteriophages are viruses that can directly infect and kill bacterial cells. Bacteriophages or phages are obligate intracellular parasites that reproduce in bacterial cells as their hosts and can be used as biocontrol agents for bacteria. The purpose of this study was to determine the effectiveness of the plaque assay method of bacteriophage that is able to infect P. aeruginosa bacteria from swiftlet pond water in South Kalimantan. The research method used was the preparation of media consisting of Nutrient Agar (NA) media, soft agar media and double layer media. The sample used in this study was one sample from the swiftlet pond water that was tested for P. aeruginosa bacteria. The plaque assay test began with the preparation of dilutions. Each dilution was taken as much as 500 μL, then inoculated on soft agar media containing 100 μL of bacterial culture and then homogenized, after which it was poured into a petri dish containing NA media. Then incubated for 24 hours at a temperature of 28°C. The results of the bacteriophage plaque assay on the pool water sample showed three dilutions that showed positive results for P. aeruginosa with clear plaque type and turbit plaque type. The number of plaques formed included the number of plaques that met the requirements, which was around 25-250. After knowing the number of plaques formed, the bacteriophage titer was calculated using the Plaque From Units (PFU/ml) unit. The bacteriophage titer calculation obtained a result of 5.1x107 PFU/mL and included a low bacteriophage titer concentration. Keywords : Bacteriophage, Swallow bird house, P. aeruginosa, Plaque assay
