ABSTRAC
Mangrove forest represent unique ekosistem with unique function in environment. Mangrove can
personate penahan of wave and also penahan of and intrusi of abrasi sea water. Mangrove forest
in all the world decrease 200.000 hectare every year, because various intensive development
pressure, like: development of infrastructure, agriculture, fishpond, other commercial or
industrial activity and urbanization.
This research aim to to know Influence Giving Vitamin Regulator Grow Gibberellic Acid (GA3)
and media plant to growth of Mangrove seed (Rhizophora mucronata Lam.). This Research
executed in Countryside of Saronggi, Sumenep, Madura on 1 June 2009-5 July 2009. Device the
used Random Device Complete with two factor. First factor is Concentration of ZPT Gibberellic
which consist of four level : (H1) Concentration of ZPT Gibberellic 50 ppm, (H2) Concentration
regulator Iihat vitamin grow (ZPT) Gibberellic 100 ppm, (H3) Concentration of ZPT Gibberellic

150 ppm, (H4) Concentration of ZPT Gibberellic 200 ppm. second Factor is media plant which
consist of : (M1) Media Mud, (M2) Media Land. Treatment combination repeated twice, is so
that obtained 24 attempt unit. Every attempt there are 10 seed, become there 240 seed which
used in this research.
From result of research which indicate that treatment of giving of regulator vitamin grow (ZPT)
Gibberellic Acid ( GA3) happened interaction to growth of mangrove crop with treatment of
concentration 100 ppm (H2) give best result to high growth [of] seed, amount of leaf, amount of
root, and root length. While media composition plant best seed mud media (M1) yielding high
growth seed, amount of leaf, amount of root, and length grow on to Mangrove crop (Rhizophora
mucronata Lam.) optimal growth
