| Judul Artikel | EFEKTIVITAS METABOLIT SEKUNDER JAMUR ENTOMOPATOGEN Lecanicillium saksenae DALAM MENGENDALIKAN HAMA WERENG BATANG COKELAT (Nilaparvata lugens) PADA TANAMAN PADI |
|---|
| Abstrak (Bhs. Indonesia) | Tanaman padi merupakan komoditas pangan utama di Indonesia. Namun pada tahun 2023 terjadi penurunan luas panen sebesar 2,45% akibat berbagai faktor, salah satunya serangan hama wereng batang cokelat (WBC). Pengendalian WBC umumnya dilakukan dengan pestisida kimia, namun penggunaan berlebih dapat merusak lingkungan. Alternatifnya, agen hayati seperti metabolit sekunder jamur entomopatogen Lecanicillium saksenae terbukti efektif dalam uji laboratorium. Penelitian ini bertujuan mengkaji pengaruh konsentrasi dan frekuensi aplikasi metabolit sekunder L. saksenae terhadap intensitas kerusakan, populasi WBC, dan musuh alami. Penelitian ini dilaksanakan di lahan sawah Desa Kediri, Kecamatan Karanglewas, Kabupaten Banyumas dan Laboratorium Perlindungan Tanaman Fakultas Pertanian Unsoed, dari Juli hingga Desember 2024 menggunakan Rancangan Acak Kelompok faktorial dengan dua faktor. Faktor pertama yaitu konsentrasi metabolit sekunder JE L. saksenae yang terdiri dari kontrol, 10%, 20%, 30%, metabolit sekunder JE L. saksenae, dan Pestisida kimiawi berbahan aktif Nitenpyram. Faktor kedua yaitu frekuensi aplikasi yang terdiri dari aplikasi seminggu sekali dan aplikasi 2 minggu sekali. Setiap perlakuan diulang 3 kali. Berdasarkan hasil penelitian, metabolit sekunder terbukti efektif dalam menurunkan tingkat kerusakan tanaman padi serta mematikan WBC. Konsentrasi optimal yang memberikan hasil terbaik adalah 20%, sedangkan frekuensi aplikasi yang paling efisien adalah aplikasi seminggu sekali. Namun demikian, interaksi antara konsentrasi dan frekuensi aplikasi tidak menunjukkan pengaruh yang signifikan terhadap variabel-variabel yang diamati. |

| Abtrak (Bhs. Inggris) | Rice (Oryza sativa L.) is the primary staple food commodity in Indonesia. However, in 2023, a 2.45% decrease in harvested area was recorded, attributable to various factors, one of which was the infestation of brown planthopper (Nilaparvata lugens Stål). Control of this pest is generally carried out using chemical pesticides; however, excessive use poses environmental risks. As an alternative, biological agents such as secondary metabolites derived from the entomopathogenic fungus Lecanicillium saksenae have demonstrated effectiveness under laboratory conditions. This study aimed to evaluate the effects of different concentrations and application frequencies of L. saksenae secondary metabolites on damage intensity, brown planthopper population, and populations of natural enemies. The research was conducted from July to December 2024 in rice fields located in Kediri Village, Karanglewas District, Banyumas Regency, as well as at the Plant Protection Laboratory, Faculty of Agriculture, Jenderal Soedirman University. A factorial randomized complete block design (RCBD) was employed, comprising two factors. The first factor was the concentration of L. saksenae secondary metabolites, consisting of control, 10%, 20%, and 30%, along with a chemical pesticide containing the active ingredient nitenpyram. The second factor was the application frequency, which included weekly and biweekly applications. Each treatment was replicated three times. The results demonstrated that secondary metabolites were effective in reducing rice crop damage and in controlling brown planthopper populations. The optimal concentration was found to be 20%, while weekly application proved to be the most efficient frequency. However, the interaction between concentration and application frequency did not have a statistically significant effect on the observed variables. |
