| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui efektivitas formula biopestisida Bacillus sp. BKR 9, B. subtilis BKR 5, B. amyloliquefaciens BBR 3 dalam mengendalikan penyakit bulai dan pengaruhnya terhadap pertumbuhan tanaman jagung. Penelitian ini dilaksanakan di rumah kaca dan Laboratorium Perlindungan Tanaman Fakultas Pertanian Universitas Jenderal Soedirman selama 4 bulan dari September hingga Desember 2023. Perlakuan yang diuji adalah kemampuan isolat Bacillus sp. BKR 9, B. subtilis BKR 5, B. amyloliquefaciens BBR 3 dengan formula kaldu keong dan kombinasi kaldu keong+air kelapa dalam mengendalikan penyakit bulai. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 17 perlakuan 3 ulangan. Variabel yang diamati meliputi masa inkubasi, intensitas penyakit, efektivitas pengendalian, laju infeksi, AUDPC, kandungan saponin, tanin, dan glikosida, tinggi tanaman, jumlah daun, panjang akar, bobot segar, dan bobot kering tanaman jagung. Hasil penelitian menunjukkan bahwa biopestisida Bacillus sp. BKR 9 formula keong + air kelapa dan konsorsium Bacillus sp. BKR 9 + B. subtilis BKR 5 + B. amyloliquefaciens BBR 3 formula keong merupakan perlakuan terbaik mampu menunda masa inkubasi sebesar 22,5 dan 21,8 hsi dan menekan intensitas penyakit bulai sebesar 71,4%. Perlakuan Bacillus sp. BKR 9 formula keong + air kelapa merupakan perlakuan terbaik dalam meningkatkan komponen pertumbuhan seperti tinggi tanaman sebesar 55,9%, jumlah daun sebesar 30,9%, panjang akar 52,2%, bobot segar sebesar 69,2% dan bobot kering sebesar 78,1%. |

| Abtrak (Bhs. Inggris) | This study aims to determine the effectiveness of the biopesticide formulas Bacillus sp. BKR 9, B. subtilis BKR 5, and B. amyloliquefaciens BBR 3 in controlling downy mildew disease and their impact on the growth of corn plants. The research was conducted in the greenhouse and Plant Protection Laboratory of the Faculty of Agriculture, Universitas Jenderal Soedirman, for four months from September to December 2023. The treatments tested were the ability of Bacillus sp. BKR 9, B. subtilis BKR 5, and B. amyloliquefaciens BBR 3 isolates with snail broth formulas and a combination of snail broth and coconut water in controlling downy mildew disease. This study used a Randomized Block Design (RBD) with 17 treatments and 3 replications. The observed variables included incubation period, disease intensity, control effectiveness, infection rate, AUDPC, saponin, tannin, and glycoside content, plant height, number of leaves, root length, fresh weight, and dry weight of corn plants. The results showed that the biopesticide Bacillus sp. BKR 9 with snail broth and coconut water formula and the consortium of Bacillus sp. BKR 9 + B. subtilis BKR 5 + B. amyloliquefaciens BBR 3 with snail broth formula were the best treatments, able to delay the incubation period by 22.5 and 21.8 days, and suppress downy mildew disease intensity by 71.4%. The Bacillus sp. BKR 9 with snail broth and coconut water formula was the best treatment in improving growth components such as plant height by 55.9%, number of leaves by 30.9%, root length by 52.2%, fresh weight by 69.2%, and dry weight by 78.1% |
