| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui pengaruh campuran 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 oratorius). 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 8 perlakuan dan 3 kali ulangan. Perlakuan yang digunakan metabolit sekunder jamur entomopatogen asal Desa Cipete (A), metabolit sekunder jamur entomopatogen asal Desa Papringan (B), metabolit sekunder jamur entomopatogen asal Desa Pasir Kulon (C), campuran metabolit sekunder jamur entomopatogen asal Desa Cipete dan Desa Papringan (AB), campuran metabolit sekunder jamur entomopatogen asal Desa Cipete dan Desa Pasir Kulon (AC), campuran metabolit sekunder jamur entomopatogen asal Desa Papringan dan Desa Pasir Kulon (BC), campuran metabolit sekunder jamur entomopatogen asal Desa Cipete, Desa Papringan dan Pasir Kulon (ABC), dan Kontrol (Insektisida 0,5g/liter). Konsentrasi dari semua perlakuan adalah 10%. Variabel yang diamati adalah mortalitas, populasi, intensitas serangan, dan musuh alami hama. Hasil penelitian menunjukkan bahwa: 1) Metabolit sekunder jamur entomopatogen asal Pasir Kulon mampu membunuh walang sangit sampai 100% pada hari ke 3; 2) Perlakuan campuran ketiga metabolit sekunder jamur entomopatogen asal Cipete, Papringan, dan Pasir Kulon berpotensi menekan populasi walang sangit sampai 100%; 3) metabolit sekunder jamur entomopatogen yang berpotensi menekan intensitas serangan terbaik adalah metabolit sekunder jamur entomopatogen asal Papringan yang mampu menekan intensitas serangan sebesar 62,63%; 4) Aplikasi campuran metabolit sekunder tidak berpengaruh negatif terhadap populasi musuh alami. Musuh alami yang ditemukan adalah laba-laba predator famili Lycosa sp., Oxyopes sp., dan Tetragnathidae sp. yang mempunyai potensi untuk mengendalikan hama walang sangit. |

| Abtrak (Bhs. Inggris) | This research was aimed for knowing the effect secondary metabolit mixture 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 oratorius). 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 8 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 secondary metabolism of entomopathogenic fungi from Cipete Village (A), secondary metabolite of entomopathogenic fungi from Papringan Village (B), secondary metabolite of entomopathogenic fungi from Pasir Kulon (C), mixture of secondary metabolites of entomopathogenic fungi from Cipete and Papringan (AB), mixed secondary metabolites of entomopathogenic fungi from Cipete Village and Pasir Kulon Village (AC), mixture of secondary metabolites of entomopathogenic fungi from Papringan Village and Pasir Kulon Village (BC), mixture of secondary metabolites of entomopathogenic fungi from Cipete Village, Papringan Village and Pasir Kulon (ABC), and Controls (0.5g /liter Insecticides). The concentration of all treatments is 10%. Observation variable is mortality, intensity of the attack, and natural enemies. The conclusions were : secondary metabolite of the entomopathogenic fungi from Pasir Kulon was able to kill the stink bug up to 100% on day 3; 2) treatment of a mixture of secondary metabolites of entomopathogenic fungi, namely the ABC treatment was able to suppress the population of stink walang up to 100%; 3) secondary metabolites of entomopathogenic fungi that have the potential to suppress the intensity of the best attack is the secondary metabolite of entomopathogenic fungi from Papringan were able to reduce the intensity of stink bug attacks by 60,63%; 4) application of a mixture of secondary metabolites did not negatively affect the natural enemy population. Natural enemies found which are spiders predator Lycosa sp., Oxyopes sp., and Tetragnathidae sp. which has the potential to control pest stink pest. |
