IMPLEMENTASI TANAMAN REFUGIA DAN PERAN SERANGGA PADA TANAMAN PADI SAWAH (Oryza sativa L.) DI KABUPATEN JEMBER

Iqbal Erdiansyah, Sekar Utami Putri

Abstract

Padi di Kabupaten Jember mengalami penurunan produksi, salah satunya disebabkan oleh organisme
pengganggu tanaman. Aplikasi PHT (Pengendalian Hama Terpadu) dengan memanfaatkan musuh alami dapat
diterapkan agar ekosistem pertanaman padi seimbang. Penggunaan refugia bagi hama padi diharapkan efektif
untuk mengurangi populasi dan serangan hama. Penelitian dilakukan dari Agustus hingga Oktober 2017 di Desa
Suren, Kecamatan Ledokombo, Kabupaten Jember. Refugia yang digunakan adalah kenikir (Cosmos caudatus)
dan bunga kertas (Zinnia elegans). Pengambilan sampel acak adalah sistematis (pola zig-zag). Variabel yang
diamati adalah investasi dan klasifikasi populasi serangga. Prosedur pengumpulan data menggunakan metode
pengumpulan data primer. Populasi hama padi tertinggi diketahui pada perlakuan yang tidak berada pada tanaman
refugia di pinggir sawah dan hama yang paling dominan adalah wereng hijau poppy atau Nipothetix spp dengan
jumlah populasi rata-rata 12 ekor. Pengamatan tanaman padi yang diolah dan ditanami tanaman refugia di pinggir
sawah, diketahui populasi tertinggi pada umur 4 MST dan serangga yang diidentifikasi adalah hama. Total musuh
alami pada tanaman padi tanpa tanaman refugia sebanyak 305 ekor, tanaman padi dengan tanaman refugia
sebanyak 438 ekor. Populasi serangga musuh alami lebih besar pada tanaman padi dengan tanaman refugia. Hal
ini disebabkan sepanjang sawah ditumbuhi gulma dan tanaman refugia.

ABSTRACT
Rice is the staple food commodity of Indonesian society. Jember regency has experienced decreased in
rice production. One of cause is plant-disturbing organism. Maintenance of rice crops done by farmers so far is
by using synthetic chemical pesticides. By utilizing natural enemies, IPM application (Integrated Pest Control)
can be applied properly for rice ecosystem to be balanced. This research was conducted from August to October
2017 in Suren Village, Ledokombo Sub-district, Jember District. Refugia used in this research are seeds kenikir
(Cosmos caudatus) and Bougainvillea (Zinnia elegans). The rice variety used is Ciherang. Random sampling is
systematic (zigzag pattern). The variables observed in this research are investment and classification of insect
population. The data collection procedure uses primary data collection method. It is known that the highest rice
pest population is known in the treatment that is not in plant refugia plant on the edge of the rice field and the
most dominant pest is the green planthopper poppy or Nipothetix spp average number of population there are 12
tails. While on the observation of rice plants that are treated planted refugia plant on the edge of the rice field is
known to the highest population at age 4 MST and the pests that are identified is pest. Total natural enemies in
rice plants without refugia plants as many as 305 head, rice plant with Refugia plant as many as 438 tail. It can
be seen that in rice plants with plants Refugia larger population of natural enemy insects, this is because in the
long along the rice field fulfilled weeds and plants refugia.
Key words: Cosmos caudatus, Nipothetix spp, Zinnia elegans.
