| Judul Artikel | APLIKASI METABOLIT SEKUNDER TIGA ISOLAT Pseudomonas fluorescens TERHADAP PENYAKIT BUSUK BUAH KAKAO DI LAPANG |
| Abstrak | Penelitian ini bertujuan untuk mengkaji keefektifan metabolit sekunder Pseudomonas fluorescens isolat P60, P20 dan P8, untuk menekan penyakit busuk buah kakao dan pengaruhnya terhadap komponen produksi. Penelitian dilaksanakan di Laboratorium Perlindungan Tanaman, Fakultas Pertanian, Universitas Jenderal Soedirman, Purwokerto dan perkebunan kakao rakyat Dusun Plumbungan, Desa Putat, Kecamatan Patuk, Kabupaten Gunung Kidul, mulai November sampai Januari 2017. Penelitian menggunakan Rancangan Acak Kelompok dengan 6 ulangan dan 4 perlakuan yang terdiri atas kontrol, metabolit sekunder P. fluorescens P60, P. fluorescens P20, dan P. fluorescens P8. Variabel yang diamati adalah kejadian penyakit, intensitas penyakit, jumlah bunga, jumlah buah baru, jumlah bunga jadi buah, dan analisis senyawa fenol. Hasil penelitian menunjukkan bahwa perlakuan metabolit sekunder P. fluorescens P20 dan P8 menekan kejadian penyakit masing-masing sebesar 28,86 dan 48,97%, serta intensitas penyakit masing-masing sebesar 12,31, 35,87, dan 40,21%. Perlakuan P. fluorescens P60, P20, dan P8 belum mampu meningkatkan jumlah bunga, buah baru. Perlakuan P. fluorescens juga mampu meningkatkan kandungan senyawa fenol pada tanaman kakao. |
| Abstrak (Inggris) | This study aims to study the secondary metabolites effectiveness Pseudomonas fluorescens isolates P60, P20 and P8, to supress the cocoa pod rot and to their effect production component. The research conducted at the Laboratory of Plant Protection, Faculty of Agriculture, Jenderal Sudirman University, Purwokerto and cocoa plantation at Putat Village, Patuk Subdistrict, Gunung Kidul Regency, from November 2016 up to January 2017. Randomized block design was used sixth replicants and fourth treatments consist of control, secondary metabolites of P. fluorescens P60, P. fluorescens P20, and P. fluorescens P8. Variables of served were disease incidence, disease intensity, number of flower, number of new poats, number of flower become poats, and compounds phenolic. Result of the reseach showed that secondary metabolites of P. fluorescens P20, and P8 surpress the disease incidence as 28.86 and 48.97%, respectively and disease intensity as 35.87 and 40.21% respectively. All treatment did not affect significantly on number of flower and number of new poats. All treatment of P. fluorescens secondary metabolites were also able to increase the content of phenolic compounds in the cocoa plant. |
