| Judul Artikel | POPULASI DAN INTENSITAS SERANGAN HAMA ULAT GRAYAK (Spodoptera litura F.) DI BEBERAPA UMUR TANAMAN DAN VARIETAS TEMBAKAU |
| Abstrak (Bhs. Indonesia) | Penelitian dilaksanakan di sentra tanaman tembakau wilayah Kabupaten Banyumas yaitu di lima desa yang berada di empat kecamatan, yaitu: Desa Cindaga Kecamatan Kebasen, Desa Losari Kecamatan Rawalo, Desa Bantar Kecamatan Jatilawang, dan Desa Pengadegan serta Desa Kelapa Gading Kecamatan Wangon. Penelitian menggunakan metode survei, dengan metode pengambilan sampel secara Purpossive random sampling. Faktor yang diamati adalah umur tanaman dan varietas. Variabel yang diamati meliputi populasi dan intensitas serangan hama ulat grayak. Data varietas tanaman yang diperoleh dianalisis dengan uji T, sedangkan data umur tanaman yang diperoleh dianalisis dengan uji F, apabila berbeda nyata dilanjutkan dengan BNT taraf 5 persen. Hasil penelitian menunjukkan bahwa populasi dan intensitas serangan hama ulat grayak tertinggi berada pada umur 46 sampai 60 hst dengan populasi 3,40 ulat grayak/9m2 dan intensitas serangan sebesar 19,70 persen. Populasi dan intensitas serangan hama ulat grayak tertinggi berada pada varietas jember dengan populasi ulat grayak sebesar 2,45 ulat grayak/9m2 dan intensitas serangan sebesar 18,78 persen. |
| Abtrak (Bhs. Inggris) | The research was conducted at the tobacco plant center in areas of Banyumas Regency located at five villages within four districts. They were Cindaga Villages at Kebasen District, Losari Villages at Rawalo District, Bantar Village at Jatilawang District, Pengadegan and Kelapa Gading Villages at Wangon District. It was a survey and the sampling method used was purposive random sampling. Plant ages and varieties were the observed factors. Variables observed were population and attack intensity of the army worm. Data of plant varieties obtained were analyzed by using T test, whereas plant ages were analyzed by using F test, and significant then continued with LSD of 5%. Results of the research performed that the highest population and the attack intensity of the army worm pest were on the plants of 46-60 days after planting shown by the population of 3.40 army worm larvae/9m2 and the attack intensity of 19.70%. The highest population and the attack intensity of the army worm pest were on the jember variety shown by the population of 2.45 army worm larvae/9m2 and the attack intensity of 18.78%. |
