Abstract

Abstrak Salah satu gangguan pertanaman tebu adalah lapuk akar dan lapuk pangkal batang tebu yang disebabkan oleh Xylaria sp. Walaupun Xylaria sp merupakan cendawan saprofit namun perlu pengendalian berupa aplikasi agensia hayati. Tujuan penelitian adalah menyeleksi cendawan yang dapat berpotensi sebagai cendawan antagonis yang mampu menghambat pertumbuhan Xylaria sp. Penelitian dilaksanakan di Laboratorium Bioteknologi Fakultas Pertanian Universitas Lampung bulan Mei sampai Agustus 2016. Penelitian tahap pertama berupa seleksi cendawan yang berpotensi sebagai antagonis berdasarkan daya hambat penelitian menggunakan rancangan acak lengkap (RAL). Penelitian tahap dua adalah seleksi isolat cendawan yang berpotensi sebagai antagonis berdasarkan pertumbuhan koloni, kerapatan spora dan viabilitas spora menggunakan rancangan acak kelompok (RAK) yang dikelompokkan berdasarkan ulangan sebanyak tiga kali. Data yang diperoleh kemudian dianalisis dengan menggunakan sidik ragam dan dilanjutkan dengan uji Duncan pada taraf 5%. Hasil penelitian diperoleh 34 isolat cendawan yang berpotensi sebagai agensia hayati dan terdapat 3 isolat unggulan dari genus Trichoderma sp. Kata kunci: Cendawan antagonis, Trichoderma sp., Xylaria sp. Abstract One of the problems found in sugar cane plantation is root and basal stem rots caused by Xylaria sp. Even though it belongs to saprophpyte fungi, Xylaria sp., needs to be controlled through life agenct application. The purpose of the present study was to select potential fungi to supress the growth of Xylaria sp. The study was conducted in the Laboratory of Biotechnology of Agriculture Department, Lampung Universiy, from May to August 2016. The first stage of this research was selection of potential fungi based on supressive ability. At this stage, the research was designed using complete randomized design (CRD). The second stage was selection of isolates in fungi potential to be antagonyst based on growth of the colony, and density and viability of spore. At this stage, the research was designed using complete randomized block design and conducted in three replications. The collected data were then analysed using ANOVA and continued with Dunncan test at 5% confidence. The research showed that there were 34 isolates of fungi
