| Judul Artikel | UJI KEMAMPUAN ENAM ISOLAT MIKROBA ANTAGONIS UNTUK MENGENDALIKAN PENYAKIT LAYU BAKTERI (Ralstonia solanacearum) PADA TANAMAN TOMAT |
| Abstrak (Bhs. Indonesia) | ABSTRAK Layu bakteri merupakan penyakit utama pada tanaman tomat yang disebabkan oleh bakteri Ralstonia solanacearum. Mikroba antagonis merupakan alternatif pengendalian yang ramah lingkungan. Tujuan penelitian ini adalah 1. Mengetahui kemampuan enam isolat mikroba antagonis dalam mengendalikan serangan bakteri penyakit layu bakteri pada tanaman tomat. 2. Mengetahui kemampuan enam asolat mikroba antagonis dalam meningkatkan pertumbuhan dan hasil tanaman tomat. Penelitian ini dilaksanakan di lahan percobaan milik Fakultas Pertanian Universitas Jenderal Soedirman, Kelurahan Karawangkal, Kecamatan Purwokerto Utara, Kabupaten Banyumas ( ± 110 m mdpl). Penelitian dilaksanakan sejak bulan Agustus 2014 sampai bulan Oktober 2014. Penelitian menggunakan Rancangan Acak Kelompok dengan 8 perlakuan dan 4 kali ulangan. Perlakuan yang dicoba meliputi: Kontrol (tanpa perlakuan), Trichoderma sp. TS1, Trichoderma sp. TS2, Gliocladium sp. TS32, Bacillus sp 42, Bacillus sp 64, Pseudomonas fluorescens 42 dan bakterisida. Variabel yang diamati meliputi masa inkubasi, intensitas penyakit, bobot buah, bobot akar segar, bobot tajuk dan tinggi tanaman. Hasil penelitian menunjukan mikroba antagonis Trichoderma sp. TS 1, Gliocladium sp. TS 32, Bacillus sp. 42, Bacillus sp. 64, P. fluorescens 42, mampu mengendalikan penyakit layu bakteri dengan penekanan berturut-turut, 91,37%, 61,17%, 83,63%, 71,24%, dan 71,13%. Enam mikroba antagonis belum mampu meningkatkan pertumbuhan dan hasil tanaman tomat. |
| Abtrak (Bhs. Inggris) | ABSTRACT Bacterial wilt is a major disease in tomato plants caused by the bacteria Ralstonia solanacearum. Antagonistic microbes are an environmentally friendly alternative control. The purpose of this research is 1. Knowing the ability of six isolates of antagonistic microbes to control bacterial wilt disease on tomato plants. 2. Knowing the ability of antagonistic microbes in improving growth and yield of tomato plants. This research was conducted at the experimental field of the Faculty of Agriculture, Jenderal Soedirman University , Karawangkal Village, District of North Purwokerto , Banyumas ( ± 110 m asl). This research was 2 conducted from August 2014 through October, 2014. Research using randomized block design with 7 treatments and 4 replications. The treatments were tested include : control ( no treatment ) , Trichoderma sp . TS1 , Trichoderma sp. TS2 , Gliocladium sp. TS32, Bacillus sp 42, Bacillus sp. 64, Pseudomonas fluorescens 42 , and bactericide. Observed variables include the incubation period , the intensity of the disease , disease suppression , fruit weight , fresh root weight , fresh weight and height of the plant canopy. The results showed antagonistic microbes Trichoderma sp. TS 1 , Gliocladium sp. TS 32 , Bacillus sp. 42 , Bacillus sp. 64 , P. fluorescens 42 , have able to control bacterial wilt disease, 91,37%, 61,17%, 83,63%, 71,24%, and 71,13%. Antagonistic microbes have not been able to increase growth and yield of tomato plants. |
