| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui pengaruh metabolit sekunder jamur entomopatogen isolat asal Desa Cipete, Papringan, dan Pasir Kulon terhadap 1) intensitas serangan, 2) mortalitas hama, dan 3) populasi musuh alami hama penggerek batang padi kuning (Scircpophaga incertulas). Penelitian ini dilaksanakan di Laboratorium Perlindungan Tanaman Fakultas Pertanian Universitas Jenderal Soedirman dan sawah percobaan di Desa Pasir Kidul, Purwokerto Barat, Banyumas, Jawa Tengah pada bulan Oktober 2018 sampai Maret 2019 menggunakan Rancangan Acak Kelompok (RAK) Non Faktorial dengan 11 perlakuan dan 3 kali ulangan. Perlakuan yang digunakan adalah kontrol (P0), isolat asal Desa Cipete dengan konsentrasi: 5 % (P1), 10 % (P2), 15 % (P3), isolat asal Papringan dengan konsentrasi: 5 % (P4), 10 % (P5), 15 % (P6), isolat asal Desa Pasir Kulon dengan konsentrasi 5 % (P7), 10 % (P8), 15 % (P9), dan insektisida imidakloprid 2 ml/L (P10). Variabel pengamatan yang diamati adalah mortalitas hama, intensitas serangan, dan populasi musuh alami hama. Hasil penelitian menunjukkan bahwa metabolit sekunder jamur entomopatogen: 1) isolat P3, P4 dan P6 dapat menekan intensitas serangan hama penggerek batang padi kuning (Scirpophaga incertulas) di lapang hingga 0 % pada fase vegetatif (7 mst). P3 dapat menekan intensitas serangan hingga paling rendah, yaitu 23,12 % di bawah perlakuan kontrol dan 17,65 % di bawah perlakuan insektisida pada fase generatif (13 mst); 2) isolat P7 menimbulkan kematian tercepat pada jam keempat dan berturut-turut P7, P4, dan P5 mampu menyebabkan kematian imago penggerek batang padi kuning (Scirpophaga incertulas) ≥ 80 % mulai hari kedua setelah aplikasi; 3) isolat asal Desa Cipete, Papringan, dan Pasir Kulon pada seluruh konsentrasi tidak berdampak negatif terhadap musuh alami yang meliputi Lycosa sp., Coccinella sp., Paederus sp., Oxyopes., Atypena sp., dan Agriosnemisfemina sp. |

| Abtrak (Bhs. Inggris) | This research was aimed for knowing the effect of secondary metabolites entomopathogenic fungi originated from Cipete, Papringan, and Pasir Kulon village on to intensity of the attack, on mortality, and on population of natural enemy of yellow stem borer (Scirpophaga incertulas). This research was conducted in Plant Protection Laboratory of Agriculture Faculty, Jenderal Soedirman University and the yield on Pasir Kidul village, Weast Purwokerto, Banyumas Regency, Center of Java on Oktober to March 2019. Laboratory test was used a completely randomized block (CRB) Non Factorial with 11 treatments and 3 replications. Each plastic confinement fill in by 10 adult and plot size is 2 m x 1 m with spacing 25 cm x 25 cm.. The treatments respectively were control (P0), isolate from Cipete village with concentration 5 percent (P1), isolate from Cipete village with concentration 10 percent (P2), isolate from Cipete village with concentration 15 percent (P3), isolate from Papringan with concentration 5 percent (P4), isolate from Papringan with concentration 10 percent (P5), isolate from Papringan with concentration 15 percent (P6), isolate from Pasir Kulon village with concentration 5 percent (P7), isolate from Pasir Kulon village with concentration 10 percent (P8), isolate from Pasir Kulon village with concentration 15 percent (P9), and insecticide with recommended dosage (P10). Observation variable is mortality, intensity of the attack, and natural enemies. Based on DMRT test with 5 percent real level, it showed that: 1) secondary metabolites entomopathogenic fungi P3 (isolate from Cipete with concentration 10 percent), P4 and P6 (isolate from Papringan with concentration 5 and 15 percent) can reduce attack of the intensity of yellow rice stem borer (Scirpophaga incertulas) on field till 0 percent (7 weeks after planting). While on generative phase (13 weeks after planting), P3 (isolate from Cipete with concentration 15 percent) cause the lowest attack of the intensity. It is 23,12 percent under the control and 17,65 percent under insecticide treatment (imidakloprid 2 ml/L); 2) isolates secondary metabolites entomopathogenic fungi P7 (isolate from Pasir Kulon with concentration 5 percents) cause the fastest mortality at four hours after application and P7 (isolate from Pasir Kulon with concentration 5 percents), P4 (isolate from Papringan with concentration 5 percents), P5 (isolate from Papringan with concentration 10) percents cause mortality of yellow rice stem borer (Scirpophaga incertulas) ≥ 80 percent began at day two after applicantion; 3) secondary metabolites entomopathogenic fungi from Cipete, Papringan, and Pasir Kulon were not given negative impact for natural enemies, covers to Lycosa sp., Coccinella sp., Paederus sp., Oxyopes., Atypena sp., and Agriosnemisfemina sp. |
