| Judul Artikel | KAJIAN APLIKASI METABOLIT SEKUNDER DUA ISOLAT Trichoderma harzianum TERHADAP PENYAKIT KUNING PADA TANAMAN LADA |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengkaji keefektifan metabolit sekunder T. harzianum isolat jahe, bawang merah, maupun gabungannya terhadap penyakit kuning dan pengaruhnya terhadap pertumbuhan serta senyawa fenol pada tanaman lada. Penelitian telah dilaksanakan di lahan pertanaman lada di Dusun Kleben, Desa Sidorejo, Kecamatan Godean, Kabupaten Sleman, Yogyakarta dan Laboratorium Perlindungan Tanaman Fakultas Pertanian Universitas Jenderal Soedirman, Purwokerto, pada bulan Oktober sampai Desember 2016. Penelitian menggunakan Rancangan Acak Kelompok dengan 6 ulangan dan 4 perlakuan yang terdiri atas kontrol, metabolit sekunder T. harzianum isolat jahe, metabolit sekunder T. harzianum isolat bawang merah, dan metabolit sekunder T. harzianum isolat gabungan jahe dan bawang merah. Variabel yang diamati adalah kejadian penyakit, daun sakit, daun sehat, daun baru dan analisis senyawa fenol. Hasil penelitian menunjukkan bahwa perlakuan metabolit sekunder T. harzianum isolat jahe (T1) dan bawang merah (T2) mampu menekan kejadian penyakit dan daun sakit masing-masing sebesar 27,56 dan 24,89% serta 56,34 dan 56,91%. Perlakuan metabolit sekunder T. harzianum isolat jahe (T1) mampu meningkatkan jumlah daun baru sebesar 43,02%, tetapi belum mampu memberikan pengaruh nyata terhadap selisih daun sehat. Perlakuan metabolit sekunder T. harzianum mampu meningkatkan kandungan senyawa fenol (tanin dan glikosida) pada tanaman lada. |
| Abtrak (Bhs. Inggris) | This study aimed to study the effectiveness of secondary metabolites of T. harzianum ginger and shallot isolates, or the combination, against yellow diseases and the effect on growth and phenolic compounds in pepper crops. Research has been conducted in the pepper crop area at the hamlet Kleben, Sidorejo Village, Godean Subdistrict, Sleman Regency, Yogyakarta and Plant Protection Laboratory, the Faculty of Agriculture, University of Jenderal Soedirman, Purwokerto, from October to December 2016. Randomized block design was used with 6 replicates and 4 treatments consisted of control, secondary metabolites of T. harzianum ginger isolate, shallot isolate, and combined ginger and shallots isolates. The variables measured were the incidence of the disease, sick leaves, healthy leaves, new leaves and analysis of phenolic compounds. Result of the research showed that treatment of secondary metabolites of T. harzianum isolates ginger (T1) and shallot (T2) was able to suppress the incidence of the disease and sick leaves respectively 27.56 and 24.89%, and 56.34 and 56.91%. Treatment of secondary metabolites of T. harzianum ginger (T1) can could increase the number of new leaves at 43.02%, but has not been able to give real effect to the difference between healthy leaves. Treatment of secondary metabolites of T. harzianum was able to increase the content of phenolic compounds (tannins and glycosides) on pepper plants. |
