Rozikin, Khairur (2019) Keanekaragaman Jamur Entomopatogen pada Rizosfer Pertanaman Padi Dataran Tinggi dan Rendah di Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Tanaman padi (Oryza sativa L.) merupakan tanaman pangan penting, karena menghasilkan beras yang menjadi sumber bahan makanan pokok. Dalam memenuhi kebutuhan beras terdapat beberapa kendala, salah satunya adalah serangga hama. Salah satu alternatif pengendalian hama adalah memanfaatkan peran agens hayati yaitu jamur entomopatogen. Tujuan dari penelitian ini adalah mengetahui keanekaragaman jamur entomopatogen dari rizosfer pertanaman padi pada dataran tinggi dan rendah di Kabupaten Malang. Penelitian dilaksanakan pada bulan Agustus sampai bulan Oktober 2018 di Laboratorium Pengendalian Hayati Jurusan Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya Malang. Penelitian ini dilakukan dengan mengambil sampel tanah rizosfer pertanaman padi pada dataran tinggi di Kecamatan Pujon, dan Kecamatan Ngantang, dataran rendah di Kecamatan Sumberpucung dan Kecamatan Kepanjen untuk dianalisis keanekaragaman jamur entomopatogennya. Dilakukan pengamatan suhu dan kelembaban udara menggunakan alat termohigrometer HTC-2. Isolasi Jamur dari tanah dilakukan dengan metode umpan serangga (insect bait methode) menggunakan larva Tenebrio molitor. Isolat jamur entomopatogen yang diperoleh dianalisis secara deskriptif berdasarkan hasil identifikasi makroskopis dan mikroskopis menurut buku Gandjar et al. (1999) dan Watanabe (2002). Hasil isolasi jamur entomopatogen dari rizosfer tanaman padi pada dataran tinggi dan rendah diperoleh 11 isolat jamur yang terdiri dari 5 genus yaitu, Metarhizium sp. 1, Metarhizium sp. 2, Fusarium sp., Chaetomium sp., serta Mortierella sp.. Pada lahan padi dataran tinggi jumlah jamur entomopatogen yang di temukan yaitu 8 isolat yang terdiri dari 5 genus sedangkan pada dataran rendah jumlah jamur entomopatogen yang ditemukan yaitu 3 isolat yang terdiri dari 2 genus. Jamur Fusarium sp., Metarhizium sp.2, dan Chaetomium sp. hanya ditemukan pada dataran tinggi. Jamur Metarhizium sp.1 dan Mortierella sp. ditemukan pada dataran tinggi dan rendah.
English Abstract
Rice plants (Oryza sativa L.) are important food crops, because they produce rice which is a source of main food. In fulfilling the needs of rice there are several obstacles, one of which is insect pests. One alternative to pest control is utilizing the role of biological agents, namely entomopathogenic fungi. The purpose of this study was to determine the diversity of entomopathogenic fungi from rice plant rhizosphere in the high and low plains in Malang Regency. The study was conducted in August to October 2018 at the Biological Control Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Brawijaya University Malang. This research was carried out by taking samples of rhizosphere soil in rice fields in the highlands in Pujon Subdistrict, and Ngantang Subdistrict, in the lowlands in Sumberpucung Subdistrict and Kepanjen Subdistrict to analyze the diversity of entomopathogenic fungi. Observations of temperature and humidity were carried out using the HTC-2 thermohigrometer. Isolation Fungis from the soil were carried out by insect bait method using Tenebrio molitor larvae. The entomopathogenic fungi isolates obtained were analyzed descriptively based on the results of macroscopic and microscopic identification according to Gandjar et al. (1999) and Watanabe (2002). The results of the isolation of entomopathogenic fungi from the rhizosphere of rice plants in the highlands and low were obtained by 11 fungal isolates consisting of 5 genera, namely, Metarhizium sp. 1, Metarhizium sp. 2, Fusarium sp., Chaetomium sp., and Mortierella sp.. In the highland rice fields the number of entomopathogenic fungi found was 8 isolates consisting of 5 genera whereas in the lowlands the number of entomopathogenic fungi found was 3 isolates consisting of 2 genera. Fusarium sp., Metarhizium sp. 2, and Chaetomium sp. only found in the highlands. Metarhizium sp. 1 and Mortierella sp. found in the highlands and lowlands.
