Abstract :
Manila sapodilla leaf (Manilkara Zapota L) is a plant that has
potential as an antibacterial, because it contains flavonoid compounds. The
gel contains a hydrophilic base that contains manila sapodilla leaves
(Manilkara Zapota L) is a plant that has potential as an antibacterial, because
it contains flavonoid compounds. The gel contains a hydrophilic base which
has a soft consistency and feels cool on the skin. The purpose of the study
was to make an optimal gel formula for extracts of sapodilla manila leaves
with variations of gelling agent Na-CMC and carbopol that met the physical
quality test and was used as an anti-acne.
The method used is maceration with 70% ethanol as solvent. The
optimum formula was tested based on the parameters of pH, spreadability,
adhesion, viscosity. Verification of the optimal formula used by statistical
tests using one sample t test. Test the antibacterial activity of the gel
preparation by looking at the size of the inhibition zone. The data obtained
were processed with ANOVA statistics.
The results of the study found that the yield of ethanol extract of
sapodilla manila leaves was 24.17%. The combination of Na-CMC 0gram
and Carbopol 3gram based on the SLD method has a desirability value of
0.866. Based on the t test of the optimum formula, which is a value that is not
significantly different, it means that the method used is valid. The results of
the antibacterial activity of Staphylococcus aureus obtained an average value
of 16.24±0.785 while the positive control obtained an average value of
21.72±0.464, meaning that it was not equivalent to the positive control.
