EKSTRAK METANOL BUAH SONNERATIA ALBA J.E.SM SEBAGAI PENGHAMBAT PERTUMBUHAN HELMINTHOSPORIUM SP. YANG DIISOLASI DARI DAUN JAGUNG
ABSTRACT: Control of corn leaf
blight caused by the fungus Helminthosporium sp., can be carried out by
employing natural antifungal of plant extract. One of the plants that have the
potential as an antifungal is Sonneratia alba J.E.Sm. The aim of this study is
to determine the ability of S. alba fruit as antifungal and to determine the
concentration of S. alba fruit extract, that can inhibit the growth of fungus
Helminthosporium sp., at the level of very strong activities. Testing of
antifungal activity of the fruit extract of S. alba carried out by employing 7
treatments, which the treatments are negative control, solvent control (DMSO
10%), positive control (Dithane M45 10%), concentration of fruit extracts
S.alba (25 %, 50%, 75% and 100%). Based on phytochemical test indicates that
fruit S. alba contains class of flavonoid compunds, alkaloids and tannins. The
results of antifungal testing at level 100% concentration indicate very strong
antifungal activity (90.01%). Those conditions indicate that 100% constitutes
concentration of S. alba fruit extract, that can inhibit the growth of
Helminthosporium sp. fungus at the level of very strong activities.
