| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk; 1) mengetahui jenis tepung yang tepat untuk perbanyakan Beauveria bassiana, 2) mengetahui pengaruh media perbanyakan Beauveria bassiana dari beberapa jenis tepung terhadap mortalitas dan intensitas serangan ulat krop (Crocidolomia pavonana F.), 3) mengetahui pengaruh Beauveria bassiana terhadap bobot segar tanaman pakcoy. Penelitian dilaksanakan di Laboratorium Perlindungan Tanaman dan Screen House Fakultas Pertanian Universitas Jenderal Soedirman, Purwokerto, pada bulan Oktober 2018 sampai Januari 2019. Penelitian dilakukan melalui dua tahap yaitu in vitro dan in planta. Penelitian tahap pertama (in vitro) menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan, yaitu media perbanyakan PDB (P0), tepung kedelai 2% (P1), tepung terigu 2% (P2), tepung beras 1,5% (P3), dan tepung ketan 1,5% (P4). Penelitian tahap kedua (in planta) menggunakan Rancangan Acak Kelompok (RAK) dengan 8 perlakuan dan 4 ulangan, setiap ulangan terdapat 2 unit tanaman, perlakuan yang diujikan yaitu kontrol negatif (K-), kontrol positif (K+), media perbanyakan PDB (P0), tepung kedelai 2% (P1), tepung terigu 2% (P2), tepung beras 1,5% (P3), tepung ketan 1,5% (P4), dan pestisida Decis (P5). Variabel pengamatan pada tahap pertama yaitu kepadatan spora, lalu tahap kedua meliputi mortalitas larva, intensitas serangan, dan bobot segar tanaman. Hasil penelitian menunjukkan bahwa 1) Tepung terigu (2%) dan kedelai (2%) merupakan jenis tepung yang tepat untuk pertumbuhan B. bassiana dengan kepadatan spora 3,842 x 107 spora/ml dan 2,948 x 107 spora/ml; 2) Tepung kedelai (2%), terigu (2%), dan beras (1,5%) mampu menekan intensitas serangan C. pavonana F. sebesar 27,74%; 19,32%; dan 30,09%; 3) Pemberian B. bassiana tidak berpengaruh terhadap mortalitas C. pavonana F. dan bobot segar tanaman. |

| Abtrak (Bhs. Inggris) | This research aimed to; 1) find out the type of flour that is right for propagation of Beauveria bassiana, 2) to determine the effect of Beauveria bassiana propagation media from several types of flour on mortality and intensity of cabbage caterpillar attack (Crocidolomia pavonana F.), 3) to determine the effect of Beauveria bassiana on the fresh weight of pakcoy plants. The research was conduct at the Plant Protection Laboratory and Screen House of the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, in October 2018 until January 2019. The research was conduct through two stages, that is in vitro and in planta. The first stage of the study (in vitro) used a completely randomized design (CRD) with 5 treatments and 5 replications, that was propagation media of PDB (P0), 2% soybean flour (P1), 2% wheat flour (P2), 1.5 rice flour % (P3), and glutinous flour 1.5% (P4). The second stage of the study (in planta) used a Randomized Block Design (RBD) with 8 treatments and 4 replications, each replication has 2 units of plants, the treatment tested are negative control (K-), positive control (K +), propagation media of PDB (P0 ), 2% soybean flour (P1), 2% wheat flour (P2), 1.5% rice flour (P3), 1.5% glutinous flour (P4), and Decis pesticide (P5). The observation variable in the first stage were spore density, then the second stage included larval mortality, intensity of attack, and fresh weight of plants. The results showed that wheat flour (2%) and soybean flour (2%) were the right type of flour for the growth of B. bassiana with a spore density of 3,842 x 107 spores/ml and 2,948 x 107 spores/ml; soybean flour (2%), wheat flour (2%), and rice flour (1.5%) can reduce the intensity of C. pavonana F. attacks by 27,74%; 19,32%; dan 30,09%; and the aplication of B. bassiana did not have effect on mortality of C. pavonana F. and fresh weight of plants. |
