Abstract :
Worm disease is a health problem that is widely found in the world, nearly
2 billion people are infected with the Soil Transmitted Helminth. The diagnosis of
intestinal worms is confirmed by microscopic examination of the feces supported
by staining. Eosin and lugol have been used as dyes on microscopic examination
of feces. Teak leaf (Tectona grandis Linn.f) contain anthocyanin compounds that
can be used as natural dyes. The purpose of this study was to determine the
ability of soaked teak leaf (Tectona grandis Linn.f) to color the egg stage of the
STH (Soil Transmitted Helminth) parasite when compared with eosin 2% and
lugol 2%. The stool examination method used was sedimentation method. The
teak leaf (Tectona grandis Linn.f) soak was obtained by soaking teak leaf
(Tectona grandis Linn.f) with ethanol 96% and concentrated HCL for 24 hours. The results of staining using teak leaf (Tectona grandis Linn.f) gave an effective
value of 100% on Ascaris sp. ang Trichuris sp. eggs, and gave an effective value
of 66,7% on Hookworm eggs. Based on the Chi-square test calculations and the
Fisher Exact tables, it can be determined that the teak leaf (Tectona grandis
Linn.f) has such significant capabilities as eosin 2% and lugol 2% in coloring the
eggs stage of the STH (Soil Trasmitted Helminth) parasites.
