| dc.description.abstract | This study examines the effective concentration of temu kunci extract
(Bosenbergia pandurata) as an antibacterial inhibition zone against 3 Aerococcus sp. isolates. and 2
Streptococus sp. isolates. The method used is the ADD (Agar Diffusion Disc) method and bacterial culture
together with the bacterial count using the TPC (Total Plate Count) method. Extract concentrations used were
concentrations of 100 ppm, 200 ppm, 300 ppm, 400 ppm, 500 ppm, 600 ppm, 700 ppm, 800 ppm, 900 ppm, and
1000 ppm. Positive controls used were amoxicillin concentration of 500 ppm and negative controls using sterile
aquades. Bacteria were grown on BHIB media and then as much as 1 ml were spread on BHIA media on petri
dishes, then 20 μl drops were dropped on an antibacterial disc measuring 6 mm, then incubated at 30ºC for 48
hours and carried out also for 24 hours and 48 hours. Furthermore, in the second experiment carried out by
culture together the extract concentrations used were 600 and 800 ppm, the results showed that the concentration
of 800 ppm was greater than the growth of bacterial destruction by the ADD method and the TPC method and
the zone of inhibition of the extract against the test bacteria 10.61- 13.47 mm | en_US |
