Abstract

Endophytic bacteria repoted can produce metabolite as antifungal compound. This study was aimed to knowing and obtain antifungal compound wich are produced of endophytic bacteria to control fungal pathogen. Isolation of endophytic bacteria was done using surface sterilization method, furthermore hypersensitive reaction test of bacteria was done for selection pathogenicity of bacteria. Endophytic bacteria was tested their antagonism against fungal pathogen for selection the potential of endophytic bacteria. Isolate of endophytic bacteria which have highest growth inhibitor would be extracted and analyzed the antifungal compound. The result showed that threeisolate of endophytic bacteria wich one potentially in inhibiting fungal pathogen are isolate EF14III, ER1I and ER101. Isolate bacteria ER1I was the most effective in inhibiting the growth of fungal pathogen. Antifungal compound in isolate bacteria ER1I are fenol, lauric acid, propenoic acid, and cyclohexanone.Keywords: Antifungal compound, Endophytic Bacteria, Fungal pathogen

Abstract

Tagetes erecta  merupakan tanaman yang tumbuh liar dan mempunyai mahkota bunga berwarna oranye, mempunyai manfaat sebagai agen kemopreventif  karena mempunyai kandungan senyawa-senyawa bersifat antioksidan untuk menangkal radikal bebas. Manfaat lain dari bunga  Tagetes erecta  dapat berfungsi sebagai refugia mikrohabitat bagi beberapa jenis serangga musuh alami yang bisa menarik serangga musuh alami karena mempunyai bunga yang berwarna cerah . Penelitian bertujuan untuk melihat kadar kuantitatif dari bunga kenikir (Tagetes erecta) sehingga dapat berfungsi sebagai mikrohabitat bagi beberapa jenis musuh alami yang ada disekitar areal pertanaman petani di desa patumbak. Metode penelitian menggunakan analisa deskriptif dengan cara analisa kuantitatif kadar lutein dari bunga kenikir yang dilakukan di Laboratorium pertanian Universitas Muhammadiyah Sumatera Utara. Hasil penelitian didapat kadar kuantittif dari ekrtak T.erecta didapat kadar lutein crude sebesar 4.33 mg dan KLT dengan Rf sebesar 0.57 cm
