ABSTRACT
Abstract: Bacteria can live in a lot of liquid medium like as beverage: Sugarcane juice, Borassus flabellifer water and Cow milk. The sign of medium have bacteria is medium can be sour and wrinkle, so that medium can be to decomposing, that at long time and no fresh again. We know bacteria (Pseudomonas aeruginosa) can be colony splintering or inactive, with technique knob and 48 kHz ultrasonic in PZ (Syamsul arifin, 2013), and in this experiment to replaying technique using beverage: Sugarcane juice, Borassus flabellifer or cow milk, with strip paper of pH indicator, specification 48 kHz ultrasonic frequency, 1 VPP intensity from function generator, transmitted with 12 knob (small ball), the ultrasonic treatment is applied continuously or periodically about 3 hours and measurement every 30 minute The result observation have new phenomena in the differences pH value between no (without) ultrasonic, and with ultrasonic in mediums i.e.: The pH value in each liquid medium without ultrasonic are decrease of pH value at long time (> 5 hours or days), but with radiation continue of ultrasonic or periodic of ultrasonic are very attractive pH value. This study shows, each liquid medium has same graphic of pH schema with no ultrasonic there are decrease in the pH value (acid liquid); and pH schema in with periodic of ultrasonic of there are decrease pH value at the moment of 30 minute (with ultrasonic) and increase at 30 minute ( after no ultrasonic) and that keep on; but in with continuous ultrasonic the pH schema keep on are with constant line of the pH value in Sugarcane juice and Cow milk, but no in water of Borassus flabellifer, that the null minute has same as pH value at no ultrasonic, at the 30 minute first has decrease, at the 30 minute second has continue value, than at 30 minute third has increase value and at 30 minute forth - soon have constant value of pH as same as at no ultrasonic.
