Pseudomonas aeruginosa causes ten to fifteen percent of nosocomial infections worldwide. This is due to the intrinsic and extrinsic resistance capabilities of Pseudomonas aeruginosa. Pseudomonas aeruginosa often infects preoperative, postoperative, and catheter patients. Povidone-iodine is an antiseptic frequently used in aseptic procedures to treat sepsis. It is affordable and easy for the general population to utilize. Understanding the concentration and minimum contact time of povidone iodine to determine its efficacy against Pseudomonas aeruginosa growth. The study was conducted by the rejuvenation of bacteria, making a bacterial suspension, and inserting the Pseudomonas aeruginosa suspension into the reaction tube containing povidone iodine at varying concentrations and for varying times. Once tested, the bacteria are planted on Nutrient Broth media, as well as a test of effectiveness with the phenol coefficient. Povidone iodine with a concentration of 1% can already kill Pseudomonas aeruginosa PAO1 within 1 minute. The coefficient value of povidone iodine phenol in this study was 5,625. Pseudomonas aeruginosa PAO1 can be inhibited from growing with povidone iodine 1%. Povidone iodine is effective compared to phenols due to the results of phenol coefficients of more than 1.
