The variables measured were Survival (SR), Briefing Gender Male, Weight Absolute Growth, Growth Absolute length and Growth Daily. The results showed that the direction of the male gender is the highest in the P2 treatment (0.4 ml) with the percentage of males was 72%, survival rate (SR) were highest in treatment P3 (85%) at a dose of 0.6 ml, where as growth absolute weight of 0.27 grams (P0), the absolute growth in length by 2.87 cm (P0 and P1) and daily weight growth rate of 2.84% (P0).Key word: Guppy, Propolis, Sex Reversal, Male
