PENGENDALIAN HAMA PADA TANAMAN KUBIS DENGAN SISTEM TANAM TUMPANGSARI
Abstract
[ENGLISH]
The research of pest control at cabbage plant by inter cropping system was done at Semboro village, Semboro town, Jember Regency. The aim of this research is to find out the most effective inter cropping system to overcome the cabbage plant’s pest problem. This research uses randomized block design (RBD) with six treatments and each treatment is repeated five times. The treatments are planting monoculture cabbage, inter cropping cabbage with chili, inter cropping cabbage with marigold, inter cropping cabbage with sweet basil, inter cropping cabbage with eggplant, and inter cropping cabbage with tomato. The results shows that none of the treatments are sufficienly effective to reduce the population of both caterpillar pest, Crociodolomia binotalis or Plutella xylostella. The average population of Crociodolomia binotalis at cabbage with sweet basil’s inter cropping is lower than monoculture cabbage that is 0,89 tail/plant. The average population of Plutella xylostella for each treatment did not give a substantial different. The inter cropping of cabbage with sweet basil produces the highest weight per crop, that is 1,11 Kg/krop with grade II crop quality.
Keywords: Cabbage; Crocidolomia binotalis; Plutella xylostella; inter cropping

Penelitian pengendalian hama pada kubis dengan sistem tanam tumpangsari dilakukan di desa Semboro Kecamatan Semboro, Kabupaten Jember. Tujuan dari penelitian ini untuk mengetahui jenis tumpangsari yang efektif dalam mengendalikan hama tanaman kubis. Rancangan yang dipergunakan dalam penelitian yaitu Rancangan Acak Kelompok (RAK) dengan enam perlakuan dan diulang sebanyak lima kali. Perlakuan yang digunakan yaitu penanaman kubis monokultur, kubis tumpangsari dengan cabai rawit, kubis tumpangsari dengan kenikir, kubis tumpangsari dengan selasih, kubis tumpangsari dengan terung, dan kubis tumpangsari dengan tomat. Hasil penelitian menunjukkan bahwa masing-masing perlakuan tidak efektif dalam menekan populasi hama ulat Crocidolomia binotalis maupun ulat Plutella xylostella. Rata-rata populasi Crocidolomia binotalis pada tumpangsari kubis dan selasih hasilnya lebih rendah dibandingkan kubis monokultur yaitu 0.89 ekor/tanaman. Rata-rata populasi Plutella xylostella pada masing-masing perlakuan menunjukkan hasil yang berbeda tidak nyata. Perlakuan tumpangsari kubis dan selasih menghasilkan berat per krop paling tinggi, yaitu 1.11 Kg/krop dengan kriteria mutu II.
Kata Kunci: Kubis; Crocidolomia binotalis; Plutella xylostella; tumpangsari
