UJI AKTIVITAS REPELAN LOTION EKSTRAK ETANOL KULIT BUAH LANGSAT (Lansium parasiticum Osbeck.) TERHADAP NYAMUK Aedes aegypti
Abstract: Repellents are
substances that can provide protection from nuisance insects by interfering
with its sensory function. Lanzones fruit is known to contain triterpenoids
which have activity as repelan. This study was to examine the repellent
activity and to determine protection capacity of lotion containing ethanol
extract of lanzones (Lansium parasiticum) peel against Aedes aegypti mosquitoes. The ethanol extract
was obtained by macerating the peel with 96% ethanol. The lotion is prepared in
three extract concentrations, 15%; 20%; and 25% followed by its physical
stability evaluation and activity examination. Data of pH, viscosity and
dispersive capacity evaluation obtained were statistically analyzed using
paired samples t-test. The results showed that the lotion preparations are
stable on organoleptic observation and homogeneity evaluation. The statistical
analysis of pH, viscosity, and the dispersive capacity evaluations showed that
their results are significantly different after day 0 to day 28 storage (p>
0.05). Repellent activity examination of the lotion was carried out for 4
hours, using the Aedes aegypti mosquitoes. Of the three concentrations
examined, each concentration has different repellent activity that
concentration of 15% and 20% indicated a 100% protection up to 1 minute, and
concentration of 25% indicated up to 135 minutes
