Abstract

Masalah utama budidaya tembakau adalah serangan hama atau Arthropoda herbivora, yang dapat menurunkan produktivitasnya. Salah satu alternatif pengendalian hama yang ramah lingkungan tanpa menggunakan pestisida sintetis adalah dengan modifikasi habibat dengan insectary plant. Tujuan penelitian ini adalah mengetahui pemanfaatan insectary plant Crotalaria juncea L. dalam modifikasi lahan tembakau untuk pengendalian komunitas Arthropoda herbivora serta menekan kerusakan tembakau yang disebabkan oleh serangan Arthropoda herbivora. Lokasi penelitian adalah lahan tembakau Desa Sengonagung, Purwosari, Pasuruan, selama 4 bulan. Pengambilan sampel Arthropoda herbivora menggunakan Yellow Pan Trap, Sweep net dan metode Hand collecting, serta menghitung tingkat kerusakan daun tembakau. Sampel Arthropoda herbivora dianalisa dengan indeks keanekaragaman Shannon – Wiener (H’), kemerataan jenis (E), dan kesamaan komunitas Morisita-Horn (CMH). Analisa statistika yang digunakan adalah Anova One Way, uji korelasi dan regresi pada taraf 5%. Hasil penelitian ini adalah penggunaan modifikasi habitat insectary plant C. juncea mempengaruhi komposisi dan kelimpahan Arthropoda Herbivora di lahan modifikasi. Pengaruh modifikasi habitat mampu mengalihkan spesies Amata huebneri pada fase generatif dan Larva Spodoptera litura pada fase reproduktif. Keanekaragaman (H’) dan kemerataan jenis (E) Arthropoda Herbivora pada lahan modifikasi lebih tinggi dibandingkan pada lahan kontrol. Dan indek kesamaan komunitas CMH Arthropoda herbivora yang paling tinggi terdapat pada tembakau kontrol dan tembakau modifikasi, dengan nilai 0.6581 atau 65.81%. Penggunaan modifikasi habitat mampu mengurangi keruskan daun tembakau di lahan modifikasi. Tingkat kerusakan daun tembakau di lahan kontrol dan modifikasi terdapat perbedaan yang signifikan, ditunjukkan dengan P value 0.01. Hasil uji korelasi menunjukkan kelimpahan Arthropoda Herbivora memiliki hubungan yang kuat terhadap kerusakan daun pada insectary plant C. juncea. Hasil uji regresi menunjukkan pengaruh kelimpahan Arthropoda Herbivora dengan tingkat kerusakan daun sebesar 39.5% ============================================================================================= The main problem of Tobacco crops are pests or herbivore Arthropods attack, which may reduce its productivity. One of alternative of pest control which environmental friendly without use of synthetic pesticide is habitat modification with insectary plant. Main goal of this research is knowing the utilization of insectary plant Crotalaria juncea L. in modification of tobacco lawn to manages herbivore Arthropods community and surpresses tobacco damage which caused by attack of herbivore Arthropods. The research location is tobacco filed Sengonagung village, Purwosari, Pasuruan, during 4 month. Sample collecting of herbivore Arthropods taken using the Yellow Pan Trap, Sweep net and Hand collecting method, then calculating level of leaf tobacco damage. Herbivore Arthropods sample was analyzed with Shannon-Wiener index of diversity (H’), Species Evenness (E), and Morisita-Horn index of community similarity (CMH). Statistic analysis using Anova One Way, correlation test and regression test, with standart of 5%. The result of this research is utilization of modification habitat with insectary plant C. juncea which affects herbivore Arthropods composition and abundance in modification field. Modification habitat effects may distract Amata huebneri species at generative phase and larva Spodoptera litura at reproductive phase. Diversity (H’) and species evenness (E) herbivore Arthropods in modification field more higher than in control field. And herbivore Arthropods index of community similarity (CMH) which most high is in tobacco control dan tobacoo modification, with value 0.6581 or 65.81%. Utilization of habitat modification can reduce damage of tobacco leaves on modification field. Level of leaf tobacco damage in control and modification field there are difference of significal, shown at P value of 0.01. Result of correlation test shown abundance of herbivore Athropods has a strong connection with leaves damage at insectary plant C. juncea. Result of reggression test shown herbivore Athropods influence with rate of leaves damage at 39.5%
