Boro, Eugenius Leba (2017) Uji Ketahanan Beberapa Genotip Jagung Terhadap Serangan Hama Sitophilus oryzae Linn. (Coleoptera: Curculionidae). Sarjana thesis, Universitas Brawijaya.
Abstract
Tanaman jagung merupakan komoditas pangan terpenting kedua setelah padi. Tanaman jagung sangat bermanfaat bagi kehidupan manusia dan ternak. Jagung mengandung senyawa karbohidrat, lemak, protein, mineral, air dan vitamin. Salah satu permasalahan tanaman jagung yaitu hama gudang peyimpanan jagung. Kumbang beras (Sitophilus oryzae) ialah salah satu hama pasca panen utama dari ordo Coleoptera yang merusak biji-bijian yang disimpan termasuk jagung. Salah satu upaya pengendalian yang sehat dan ramah lingkungan yaitu penggunaan tanaman tahan yang digunakan untuk mengurangi serangan hama dan penyakit. Penelitian ini dilaksanakan di Laboratorium Hama Tumbuhan I, Jurusan Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya, mulai Oktober 2016 sampai Januari 2017. Metode Penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan enam perlakuan yaitu genotip BISI 2, BISI 16, BISI 18, BISI 22, BISI 816 dan BISMA. Penelitian ini bertujuan untuk (1) mendapatkan genotip yang tahan terhadap serangan hama S. oryzae dan (2) mengkaji ketahanan pada tiap gentotip dari enam perlakuan yang diuji. Hasil penelitian menunjukkan terdapat empat benih yang tergolong tahan yaitu BISI 2, BISI 18, BISI 22 dan dua benih yang tergolong cukup tahan yaitu BISI 16 dan BISI 816. Perbedaan tingkat ketahanan dipengaruhi oleh jumlah imago baru dan median waktu perkembangan. Jumlah imago baru dan median waktu perkembangan didapatkan melalui pengamatan pertumbuhan dan perkembangan S. oryzae. Selain itu, jumlah imago baru dan median waktu perkembangan juga dipengaruhi oleh tingkat kekerasan dan kandungan protein dalam pakan.
English Abstract
Maize is the second most important food commodity after rice. Maize very beneficial for human lives and livestock. Maize contains carbohydrates, fats, proteins, minerals, vitamins and water. One of the problems of maize is stored-product pests. Rice Weevil (Sitophilus oryzae) is one of the main post-harvest pest of the order Coleoptera which damage stored grain including maize. One of the healthy control effort and friendly environment that is the use of the resistant variety that used to reduce against the attacks of pests and diseases. This research was carried out in the laboratory of Pest, Department of Plant Pests and Disease, Faculty of Agriculture, University of Brawijaya, it was start from October 2016 until January 2017. The research method was used Completely Randomized Design (CRD) with six treatments that were BISI 2, 18, 22, 816 and BISMA. This research purposes (1) to get genotype which resistant to S. oryzae attack and (2) examine resistance in each genotype from six treatment. The results showed there were four seeds that belongs ressistant were BISI 2, 18, 22 and BISMA and two seeds that belongs enough ressistant were BISI 16 and BISI 816. The difference of the resistance level was affected by the number of new adult and the median development time. The number of new adult and the median development time were obtained through observation of the growth and development of S. oryzae. In addition, the number of new adult and the median development time were also influenced by hardness level of seed and the content of protein in diet.
