| Judul Artikel | PENGARUH KONSENTRASI DAN FREKUENSI APLIKASI METABOLIT SEKUNDER JAMUR ENTOMOPATOGEN Lecanicillium saksenae TERHADAP HAMA PUTIH PALSU (Cnaphalocrocis medinalis L.) PADA PADI |

| Abstrak (Bhs. Indonesia) | Padi merupakan tanaman pokok sebagai sumber makanan utama di Indonesia. Namun, produksinya terus menurun, salah satunya akibat serangan hama berupa putih palsu (Cnaphalocrocis medinalis). Hama putih palsu merusak daun padi, terutama saat tanaman pada masa vegetatif, sehingga menurunkan produktifitas tanaman padi. Pengendalian Hama Terpadu (PHT) perlu dilakukan menggunakan agen hayati, misalnya jamur Lecanicillium saksenae. Jamur ini diduga dapat mengendalikan hama, salah satunya dengan hasil metabolit sekundernya. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 2 faktor dengan 3 kali ulangan. Variabel yang diamati dalam penelitian ini yaitu intensitas kerusakan tanaman, populasi hama putih palsu, indeks keragaman dan dominansi musuh alami. Hasil penelitian menunjukkan bahwa: 1) konsentrasi metabolit sekunder jamur entomopatogen L. saksenae 30% tidak berpengaruh terhadap intensitas kerusakan, populasi hama putih palsu dan musuh alami; 2) frekuensi aplikasi metabolit sekunder jamur entomopatogen L. saksenae 1 minggu sekali tidak berpengaruh terhadap intensitas kerusakan, populasi hama putih palsu dan musuh alami; 3) tidak ada interaksi antara konsentrasi dan frekuensi aplikasi metabolit sekunder jamur entomopatogen L. saksenae, sehingga tidak berpengaruh terhadap intensitas kerusakan, populasi hama putih palsu, maupun tingkat keanekaragaman dan dominansi musuh alami. |

| Abtrak (Bhs. Inggris) | Rice is a staple crop as the main source of food in Indonesia. However, its production continues to decline, one of which is due to pest attacks in the form of rice leaf folder moth (Cnaphalocrocis medinalis). Rice leaf folder moth damage rice leaves, especially when the plant is in the vegetative period, thus reducing the productivity of rice plants. Integrated Pest Management (IPM) needs to be carried out using biological agents, such as the fungus Lecanicillium saksenae. This fungus is thought to be able to control pests, one of which is with the results of its secondary metabolites. This research used a Randomized Block Design (RBD) with 2 factors and 3 replications. The variables observed in this study were the intensity of plant damage, rice leaf folder moth population, diversity index and dominance of natural enemies. The results showed that: 1) the concentration of secondary metabolites of the entomopathogenic fungus L. saksenae 30% has no effect on the intensity of damage, the population of ice leaf folder moth and natural enemies; 2) the frequency of application of secondary metabolites of the entomopathogenic fungus L. saksenae once a week has no effect on the intensity of damage, the population of ice leaf folder moth and natural enemies; 3) there is no interaction between the concentration and frequency of application of secondary metabolites of the entomopathogenic fungus L. saksenae, so that it does not affect the intensity of damage, the population of ice leaf folder moth, nor the level of diversity and dominance of natural enemies. |
