Cristanti, LindaDeviana (2013) Pertumbuhan Padi Hitam dan Serangan Beberapa Herbivor Di Sawah Padi Organik Kecamatan Kepanjen. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk menentukan diversitas herbivor pengunjung padi hitam varietas Toraja di sawah padi organik di Kecamatan Kepanjen, Malang, menentukan gejala gangguan pertumbuhan padi hitam akibat serangan ringan herbivor, serta membandingkan pertumbuhan padi hitam akibat serangan tikus dengan tanaman tidak terserang. Pengamatan dilakukan di tiga petak sawah padi hitam organik pada empat umur yaitu 28, 48, 88, dan 112 hari setelah tanam (hst). Pertumbuhan padi hitam diamati tinggi rumpun, jumlah anakan, malai, spikelet dan biomassa. Pengamatan diversitas hewan pengunjung dengan metode jelajah dan visual encounter di sisi tiap petak sawah padi hitam organik menggunakan skor kelimpahan 0-4 pada jam 06.00-10.00 WIB. Diversitas hewan pengunjung ditentukan dengan kekayaan spesies, famili, dan ordo. Data pertumbuhan padi hitam yang terserang tikus dianalisis menggunakan software PAST dan SPSS. Hasil penelitian menunjukkan telah diamati enam famili herbivor pada fase vegetatif dan generatif yang mengunjungi sawah padi hitam di antaranya tikus (Muridae), burung pipit (Estrildidae), ulat penggerek batang (Pyralidae), lalat (Muscidae), lalat pucuk padi (Ephydridae) dan ngengat (Arctiidae). Serangan herbivor pengunjung terbesar pada umur 26 hst diakibatkan oleh Muride, dan fase generatif oleh Estrildidae. Walaupun pasca serangan tikus terjadi recovery pada pertumbuhan tinggi padi, namun jumlah malai dan spikelet padi menurun 10 %-55 % pada saat panen.
English Abstract
The aims of this study were to determine diversity of visiting herbivores of Toraja black rice in Kepanjen organic rice field, to determine black rice symptoms caused by herbivores attacks, to compare the normal and rat attacked black rice growth. Observations were held on three rice fields on 28, 48, 88, and 112 days after transplanting (dat). We measured plant height, number of tillers, panicle, spikes and biomass. Herbivores visitors were observed at 06.30 to 10.30 am using cruising method, visual encounter in each plot and abundance score 0 to 4. Herbivores visitor diversity was determined by species, families and orders richness. Rat attack impacts to black rice growth were analyzed using PAST and SPSS software. Results showed that there were six herbivore families found in vegetative and generative growth in black rice field, including rat (Muridae), sparrow (Estrildidae), moth borer (Pyralidae), flies (Muscidae), flies seeds (Ephydridae) and moth (Arctiidae). Significant attacks by rat were recorded on black rice grown after 26 dat, while Estrildidae attacks were taken place during generative period. Even though there was a height recovery, however rat attack in early growth decreased panicle and spikes number until 10 % to 55 % during harvesting.
