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%
