Abstract

ABSTRAK Tuti Alawiyah. 2017. Respons Beberapa Varietas Padi (Oryza sativa L.) Terhadap Wereng Batang Coklat (nilaparvata lugens Stal) Koloni Karawang. Dibawah Bimbingan Suryaman Birnadi Dan Efrin Firmansyah. Karawang merupakan salah satu daerah yang terkena dampak serangan wereng batang coklat pada usia tanam pertama tahun 2016. Penelitian ini bertujuan utuk mengetahui ketahanan beberapa varietas padi (Oryza sativa L.) terhadap serangan wereng batang coklat (Nilaparvata lugens stal) koloni Karawang melalui uji embun madu dan mendapatkan varietas yang tahan terhadap wereng batang coklat (nilaparvata lugens stal) koloni Karawang. Penelitian ini dilaksanakan di Balai Besar Peramalan Organisme Penganggu Tumbuhan (BBPOPT) Jatisari-Karawang dari bulan Februari sampai Juni 2017. Metode yang digunakan adalah metode rancangan acak lengkap (RAL) terdiri dari 10 perlakuan dan 5 ulangan yaitu : Pelita (kontrol), Ciherang, Ciliwung, Cibogo, Sintanur, Cisadane,Inpari 33, Inpari 32, Inpari 13, dan Sintanur. Uji lanjut yang digunakan adalah uji lanjut Duncan pada taraf 5%. Hasil penelitian menunjukan terdapat varietas ketahanan antar varietas padi yang diuji dilihat dari luas bercak embun keseluruhan perwereng, mortaliats wereng batang coklat, intensitas serangan. tingkat kerusakan tanaman, bobot hasil, dan nisbah pupus akar koloni karawang. Inpari 33 adalah varietas padi yang tahan terhadap serangan wereng batang coklat koloni Karawang. ABSTRACT Tuti Alawiyah. 2017. Response Of Rice Varieties (Oryza sativa L.) To Brown Plantthopper (Nilaparvata lugens Stal) Of Karawang Colonies. Supervised By Suryaman Birnadi And Efrin Firmansyah. Karawang is one of the areas that was affected by brown stem plantthoper (Nilaparvata lugens Stal) attacks on the first season of planting in 2016. The purpose of this study is to determine the resist of some varieties of rice (Oryza sativa L) on the attack of brown stem plantthoper (Nilaparvata lugens stal) of Karawang colonies through Honey Dautes test and get resistant varieties. This research was conducted at Balai Peramalan Pengganggu Tumbuhan (BBPOPT) Jatisari-Karawang from February to Juny 2017. The method used was RAL consisted of 10 treatments and 5 replications, namely: Pelita (control), ciherang, ciliwung, cibogo, sintanur, cisadane, inpari 33, inpari 32, inpari 13, and sintanur. The next test that used is Duncan's test at 5% level. The results showed that there were resist varieties between tested rice varieties from all dautes wide spotting of all brow stem, mortality of brown stem, attacks intensity, destruction level of plant, result of weight, and odds fades root of the Karawang colonies. Inpari 33 is the best rice varieties which can resist from all brown stem attack of Karawang colonies.
