Abstract :
Pneumonia is an acute infection associated with lung tissue (alveoli) that is
wrongly caused by bacteria. K. pneumonia is about 5% of normal individuals and
causes a small portion (about 1%) of bacterial pneumonia. Kitolod leaf (Isotoma
longiflora) is one of the plants that can be used as an alternative for treatment of
pneumonia. Because it contains alkaloids, flavonoids, and saponins. The purpose
of this study was to determine whether the decoction of leaves of I. longiflora can
inhibit the growth of K. pneumoniae. This research uses an experimental descriptive method. The sampling
technique used was quota sampling. The sample of this study was variations in the
concentration of the leaves of I. longiflora with concentrations of 20%, 40%, 60%,
80%, and 100%. The positive control used was Ciprofloxacin 5?g and the
negative control used a sterile aquadest. Test the inhibition of bacteria using the
disk diffusion method.
The results of the decoction of the leaves of I. longiflora are able to
overcome the growth of K. pneumoniae which support all variations of
concentration. Radical zones are formed at each concentration variation with an
average diameter of 20% concentration of 6.15 mm; 40% of 6.48 mm; 60% of
6.73 mm; 80% of 7.08 mm; and 100% of 7.48 mm.
The conclusions from the study show that every variation of the decoction
of the leaves of I. longiflora is able to make a radical zone, but it is not included in
the criteria for sensitivity to Ciprofloxacin antibiotics through CLSI 2019.
