| Judul Artikel | PENGARUH METABOLIT SEKUNDER JAMUR ENTOMOPATOGEN TERHADAP HAMA WALANG SANGIT (Leptocorisa acuta) DAN MUSUH ALAMINYA PADA TANAMAN PADI (Oryza sativa L.) |
| Abstrak | Penelitian ini bertujuan untuk mengetahui pengaruh metabolit sekunder jamur entomopatogen isolat asal Desa Cipete, Papringan, dan Pasir Kulon terhadap: mortalitas, populasi, intensitas serangan, dan populasi musuh alami hama walang sangit (Leptocorisa acuta). Penelitian 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. Penelitian 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 bahan aktif imidakloprid 0,5g/liter (P10). Variabel yang diamati adalah mortalitas, populasi, intensitas serangan, dan musuh alami hama. Hasil penelitian menunjukkan bahwa: 1) metabolit sekunder jamur entomopatogen P8 (10%) dan P9 (15%) mampu membunuh ≥80 % walang sangit pada hari ketiga.; 2) semua metabolit sekunder jamur entomopatogen yg diuji mampu menekan populasi walang sangit sebesar 77,6% - 100%; 3) metabolit sekunder jamur entomopatogen P8 (10%) dan P9 (15%) mampu menekan intensitas serangan walang sangit sebesar 92,2% dan 92,8% ; 4) metabolit sekunder jamur entomopatogen tidak mempengaruhi populasi musuh alami Lycosa sp., Atypena sp., Oxyopes sp. dan Tetragnatha sp. |
| Abstrak (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, stink bug population and on population of natural enemy stink bug (Leptocorisa acuta). This research was conducted in Plant Protection Laboratory of Agriculture Faculty, Jenderal Soedirman University and the yield on Pasir Kidul village, West 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% (P1), 10% (P2), 15% (P3), isolate from Papringan with concentration 5% (P4), 10% (P5 15% (P6), isolate from Pasir Kulon village with concentration 5% (P7), 10% (P8), 15% (P9), and insecticide imidakloprid 0,5g/litre (P10). Observation variable is mortality, intensity of the attack, and natural enemies. The conclusions were : 1) secondary metabolites of entomopathogenic fungi P8(10%) and P9 (15%) were able to kill ≥80% of stink bug on the third day; 2) all the secondary metabolites of the entomopathogenic fungi tested were able to suppress the stink bug population by 77.6% - 100%; 3) the secondary metabolites of entomopathogenic fungi P8 (10%) and P9 (15%) were able to reduce the intensity of stink bug attacks by 92.2% and 92.8%; 4) Secondary metabolites of entomopathogenic fungi do not affect the natural enemy population of Lycosa sp., Atypena sp., Oxyopes sp. and Tetragnatha sp . |
