|---|
| Abstrak (Bhs. Indonesia) | Jagung merupakan komoditas pangan yang berperan penting dalam pemenuhan kebutuhan bahan baku pakan ternak, pangan, dan industri. Tujuan penelitian yaitu untuk mengetahui kemampuan bakteri endofit P. fluorescens dan Bacillus sp. dalam menghambat pertumbuhan jamur patogen R. solani secara in vitro, mengetahui efektivitas bakteri endofit P. fluorescens dan Bacillus sp. dalam mengendalikan penyakit hawar pelepah pada tanaman jagung secara in vivo, dan mengetahui pengaruh aplikasi bakteri endofit P. fluorescens dan Bacillus sp. terhadap pertumbuhan tanaman jagung. Penelitian dilaksanakan mulai Oktober 2020 sampai dengan April 2021, di Laboratorium Perlindungan Tanaman dan screen house Fakultas Pertanian Universitas Jenderal Soedirman, Purwokerto. Rancangan percobaan yang digunakan yaitu Rancangan Acak Kelompok dengan perlakuan bakteri endofit Bacillus sp. Kembaran B1, Bacillus sp. Baturraden B4, P. fluorescens Padamara B5. Variabel yang diamati yaitu pengujian in vitro meliputi penghambatan pertumbuhan jamur R. solani dan bobot kering miselium; pada pengujian in vivo meliputi masa inkubasi penyakit, intensitas penyakit, kejadian penyakit, AUDPC, serta komponen pertumbuhan tanaman. Hasil penelitian menunjukkan bahwa Bacillus sp. Kembaran B1 memberikan pengaruh terbaik dalam menghambat jamur R. solani secara in vitro sebesar 74,6% dan bobot kering miselium dengan nilai terkecil 0,04 g. Bacillus sp. Kembaran B1 memberikan pengaruh terbaik dalam pengujian in vivo dengan penekanan kejadian penyakit sebesar 55%, penekanan intensitas penyakit sebesar 42,11%, penekanan AUDPC sebesar 61,90%. Bacillus sp. Kembaran B1 memiliki pengaruh terbaik terhadap pertumbuhan tanaman jagung dalam meningkatkan tinggi tanaman sebesar 150,35 cm dan bobot tanaman segar sebesar 139,65 g. |

| Abtrak (Bhs. Inggris) | Maize is an important food commodity in the needs of raw materials for animal feed, food, and industry. This research aims to determine the ability of endophytic bacteria P. fluorescens and Bacillus sp. in inhibiting the growth of the pathogenic fungus R. solani in vitro, identify the effectiveness of the endophytic bacteria P. fluorescens and Bacillus sp. in controlling sheath blight blight on maize in vivo, and observe the effect of application of endophytic bacteria P. fluorescens and Bacillus sp. on maize growth. The research was carried out from October 2020 to April 2021, at the Plant Protection Laboratory and screen house Faculty of Agriculture, Jenderal Sudirman University, Purwokerto. The research design used was a Randomized Block Design with 1 factor, the treatment of endophytic bacteria. The variables observed were in vitro testing including inhibition of the growth of the fungus R. solani and dry weight of mycelium; In vivo testing includes disease incubation period, disease intensity, disease incidence, AUDPC, and plant growth components. The results showed that in vitro testing, the treatment of Bacillus sp. Kembaran B1 gave the best effect in inhibiting the fungus R. solani 74.6% and dry weight of mycelium with the smallest value 0.04 g. Bacillus sp. Kembaran B1 gave the best effect in vivo testing with suppression of disease incidence by 55%, suppression of disease intensity by 42.11%, suppression of AUDPC by 61.90%. Bacillus sp. Kembaran B1 gave the best effect on the growth of maize plants in increasing plant height by 150.35 cm and fresh plant weight by 139.65 g. |
