| Judul Artikel | APLIKASI METABOLIT SEKUNDER GABUNGAN DUA ISOLAT Trichoderma harzianum DAN TIGA ISOLAT Pseudomonas fluorescens TERHADAP PENYAKIT BUSUK BUAH KAKAO |
| Abstrak | Penelitian bertujuan mengkaji keefektifan metabolit sekunder gabungan dua isolat Tricoderma harzianum Rifai dan tiga isolat Pseudomonas fluorescens Migula terhadap penyakit busuk buah kakao serta pengaruhnya terhadap komponen produksi kakao. Penelitian dilaksanakan di perkebunan kakao rakyat, Dusun Gumiwang, Desa Putat, Kecamatan Patuk, Kabupaten Gunung Kidul, Yogyakarta, mulai November 2016 sampai Januari 2017. Penelitian menggunakan Rancangan Acak Kelompok dengan 4 ulangan dan 7 perlakuan terdiri atas kontrol, gabungan metabolit sekunder T. harzianum bawang merah+P. fluorescens P8, T. harzianum bawang merah+P. fluorescens P20, T. harzianum bawang merah+P. fluorescens P60, T. harzianum jahe+P. fluorescens P8, T. harzianum jahe+P. fluorescens P20, dan T. harzianum jahe+P. fluorescens P60. Variabel yang diamati meliputi: kejadian penyakit, intensitas penyakit, jumlah bunga dan jumlah bunga jadi buah. Hasil penelitian menunjukkan bahwa perlakuan bawang merah+P8, jahe+P8, bawang merah+P20, jahe+P20, jahe+P60, bawang merah+P60 mampu menekan kejadian penyakit berturut-turut sebesar 80,19; 66,42; 51,37; 45,93; 45,29; dan 42,31%, serta menekan intensitas penyakit berturut-turut sebesar 81,99; 75,63; 59;14; 62,43; 54,41; 47,05%. Perlakuan Jahe+P20, jahe+P8, jahe+P60 dan bawang merah+P8 mampu meningkatkan jumlah bunga jadi buah berturut-turut sebesar 27,38; 23,44; 4,90; 5,26%. Namun, semua perlakuan belum mampu meningkatkan jumlah bunga. Perlakuan jahe+P20, bawang merah+P20 dan bawang merah+P60 mampu mengingkatkan senyawa fenol buah kakao. |
| Abstrak (Inggris) | This research aimed to study the effectiveness of secondary metabolites combined from two Tricoderma harzianum Rifai isolates and three Pseudomonas fluorescens Migula isolates towards pod rod disease of cocoa and their influence on cocoa production components. The research was conducted in the cocoa plantations at Gumiwang hamlet, Putat Village, Patuk Sub-District, Gunung Kidul Regency, Yogyakarta from November 2016 up to January 2017. Randomized block design was used with 4 replicates and 7 treatments consisted of control, combined secondary metabolites from T. harzianum shallot+P. fluorescen P8, T. harzianum shallot +P. fluorescens P20, T. harzianum shallot +P. fluorescens P60, T. harzianum ginger+P. fluorescens P8, T. harzianum ginger+P. fluorescens P20, and T. harzianum ginger+P. fluorescens P60. Variables observed were disease incidence, disease intensity, number of flower and number of flower become fruit. Research of the result indicated that the secondary metabolites of T. harzianum shallot+P8, ginger+P8, shallot+P20, ginger+P20, ginger+P60, shallot+P60 could suppress the disease incidence as 80,19; 51,37; 45,93; 45,29; and 42.31%, respectively, and suppress the disease intensity as 81,99; 75,63; 59,14; 62,43; 54,41; 47,05%, respectively. Secondary metabolites of T. harzianum ginger+P20, ginger+P8, ginger+P60, and shallot+P8 increase the number of flower become fruit as 27,38; 23,44; 4,90; 5,26%, respectively. However, all the tratment could not increase the number of flower. The secondary metaboluites of T. harzianum ginger+P20, shallot+P20 and shallot+P60 increase phenolic compound in cocoa fruit. |
