Uji Preferensi Wereng Batang Coklat (Nilaparvata lugens Stal.) Pada Tanaman Padi Sawah, Padi Gogo dan Rumput Teki (Cyperus rotundus L.) di Rumah Kasa

ABSTRACT
SANTI FIORA SINAGA, 2015. “The preferences test of Brown Planthopper
(Nilaparvata lugens Stal.)on Irrigated paddy field, Nonirrigated paddy field and
Sedges (Cyperus rotundus L.) at Screenhouse.” Supervised by Marheni and
Mukhtar Iskandar Pinem. The objectives of this research was study the preference
of feeding activity of brown planthopper (N. lugens) on irrigated paddy field,
nonirrigated paddy field and sedges (C. rotundus) in field. This research was held
at screenhouse in Faculty of Agriculture, University of Sumatera Utara fromJuni
to August 2015. This research used a non factorial Block Randomized Design
method with 3 treatments, namely: Irrigated paddy field, nonirrigated paddy field
and sedges with 9 replications. The result showed that the highest population of
adults wereon Irrigated paddy field treatment (±6.00) and the lowest (±1.11) was
on sedges treatment. The highest population of nymph was on Irrigated paddy
field treatment (±25.56) and the lowest on sedgestreatment (±0.00). The highest
attact percentage of N. lugens was on treatment Irrigated paddy field
treatment(33.65%) and followed by nonirrigated paddy field treatment(8.51%)
and the lowest on sedges) treatment (1.17%).
Key words: Preference, N. lugens, irrigated paddy field, nonirrigated paddy field,
sedges

ABSTRAK
SANTI FIORA SINAGA, 2016.“Uji Preferensi Wereng Batang Coklat
(Nilaparvata lugens Stal.) Pada Tanaman Padi Sawah, Padi Gogo dan Rumput
Teki (Cyperus roduntusL.) di Rumah Kasa” di bawah bimbingan Marheni dan
Mukhtar Iskandar Pinem. Penelitian ini bertujuan untuk mengetahui preferensi
makan hama wereng batang coklat (N. lugens) pada tanaman padi sawah, padi
gogo dan rumput teki (C. rotundus) di lapangan. Penelitian ini dilaksanakan di
Rumah Kasa Fakultas Pertanian Universitas Sumatera Utara padabulan Juni
sampai Agustus 2015. Penelitian ini menggunakan metode Rancangan Acak
Kelompok (RAK) non faktorial yang terdiri dari 3 perlakuan, yaitu: Padi Sawah,
Padi Gogo dan Rumput Teki dengan 9 ulangan. Hasil penelitian menunjukkan
bahwa populasi imago tertinggi pada perlakuan Padi Sawah (±6.00) dan terendah
pada perlakuan Rumput Teki (±1.11). Populasi nimfa tertinggi terdapat pada
perlakuan Padi Sawah (±25.56) dan terendah pada perlakuan Rumput Teki
(±0.00). Kemudian persentase serangan hama N. lugens tertinggi terdapat pada
perlakuan Padi Sawah (33.65%) setelah itu diikuti perlakuan Padi Gogo (8.51%)
dan terendah pada perlakuan Rumput Teki (1.17%).
Kata Kunci: Preferensi, N. lugens, padi sawah, padi gogo, rumput teki
