Aktivitas Antagonistik Endofit Fusarium solani EnI dari Bunga Bawang Dayak terhadap Aspergillus flavus, Kontaminan dari Kacang Kedelai: Antagonistic Activities of Endophytic F. solani EnI from Eleutherine palmifolia Flower againts Aspergillus flavus, Contaminants from Soybean

Endophytic fungi are one of the biological control agents whose ability has recently been reported to protect plants from environmental stress, both pests, and diseases. The endophytic fungus Fusarium solani EnI has been isolated from the flowers of the Dayak onion medicinal plant in the wetland environment of South Kalimantan, which can be used as agent biological control to plant pathogen. This study to determine the antagonism ability of the endophytic fungus from Dayak onion flower, F. solani EnI against Aspergillus flavus which contaminates soybeans. Parameters observed in this study, the inhibition of endophytic fungi to F. solani En1 using the dual culture method. The results showed a variation in the percentage of inhibition of the endophytic fungus F. solani EnI against the contaminant fungus A. flavus soybean in vitro on three culture media, which are PDA is 36.67%, soybean media is 31.19%, and corn media is 25%.Cendawan endofit merupakan salah satu agen pengendali biologi yang akhir akhir ini dilaporkan kemampuanya dalam melindungi tanaman dari stres lingkungan baik serangan hama dan penyakit. Cendawan endofit Fusarium solani EnI telah diisolasi dari bunga tanaman obat Bawang Dayak di wilayah lingkungan lahan basah Kalimantan Selatan dapat digunakan sebagai pengendali pertumbuhan patogen tanaman. Penelitian ini bertujuan untuk mengetahui kemampuan antagonisme cendawan endofit dari bunga bawang dayak, yaitu Fusarium solani EnI serta terhadap cendawan Aspergillus flavus yang mengkontaminasi kacang kedelai. Parameter pengamatan penelitian ini, daya hambat cendawan endofit ke Fusarium solani En1 menggunakan metode dual culture. Hasil penelitian menunjukkan adanya ragam persen daya hambat cendawan endofit F.solani EnI terhadap cendawan kontaminan kacang kedelai A.flavus secara in vitro pada tiga media tumbuh, yaitu pada media PDA sebesar 36,67%, media kedelai sebesar 31,19%, dan media jagung sebesar 25%
