| Judul Artikel | KAJIAN APLIKASI METABOLIT SEKUNDER DUA ISOLAT Trichoderma sp. TERHADAP PERTUMBUHAN VEGETATIF BIBIT LADA PERDU |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengkaji pengaruh metabolit sekunder dua isolat Trichoderma sp., yaitu isolat jahe dan bawang merah maupun gabungannya, terhadap pertumbuhan vegetatif, serta pengaruhnya terhadap kandungan senyawa fenol pada bibit lada perdu. Penelitian telah dilaksanakan di Laboratorium Perlindungan Tanaman dan Desa Banteran Kecamatan Sumbang, Kabupaten Banyumas, mulai Oktober 2015 sampai Januari 2016. Penelitian menggunakan Rancangan Acak Kelompok dengan 6 ulangan. Perlakuan terdiri atas kontrol, metabolit sekunder Trichoderma sp. isolat jahe, isolat bawang merah, gabungan isolat jahe dan bawang merah, serta fungisida berbahan aktif benomil. Variabel yang diamati adalah tinggi tanaman, diameter batang, jumlah daun, panjang daun, luas daun, jumlah cabang, bobot tanaman segar dan kering, bobot akar segar dan kering, panjang akar dan analisis senyawa fenol secara kualitatif. Hasil penelitian menunjukkan bahwa penerapan metabolit sekunder Trichoderma sp. isolat jahe, isolat bawang merah dan gabungan keduanya memberikan nilai penambahan tinggi tanaman 36,18-48,21%, diameter batang 8,33-13,72%, jumlah daun 43,67-47,02%, bobot tanaman segar 20,02-21,57%, bobot akar segar 31,99-33,95%, bobot akar kering 30,76-33,33%, panjang akar 17,07-18,26% dibanding kontrol dan mampu meningkatkan senyawa fenol.Penerapan gabungan metabolit sekunder Trichoderma sp. isolat jahe dan isolat bawang merah memberikan potensi terbaik dalam meningkatkan penambahan tinggi tanaman (48,21%), lebar diameter batang (13,72%), bobot tanaman segar (21,57%) dan bobot akar segar (33,95%). |
| Abtrak (Bhs. Inggris) | This study aimed to assess the effect of secondary metabolites from two Trichoderma sp. Isolatesthat were ginger and shallot isolates or their combination, on the vegetative growth of non climbing pepper seedling, as well as its influence on the content of phenolic compounds in the seedlings. This research was carried out at the Laboratory of Plant Protection and at Banteran Village, Sumbang Sub-District, Banyumas Regency, from October 2015 to January 2016. Randomized block design was used with five treatments six replicates. The treatments were control, secondary metabolit of Trichoderma sp. ginger and shallots isolates, their combination and fungicide with active ingredient of benomil. Variables observed were plant height, stem diameter, number of leaves, leaf length, leaf area, number of branches, weight of fresh and dry plants, weight of fresh and dry roots, root length and analysis of phenolic compounds qualitatively. Results of theresearch showed that the application of secondary metabolites from Trichoderma sp. ginger and shallots isolates, and their combination provided value addition of plant heightas 36.18-48.21%, stem diameter as8.33-13.72%, number of leaves as 43.67-47.02%, fresh weight of plant as 20,02-21.57%, fresh weight of root as 31.99-33.95%, dried weight of rootas 30.76-33.33%, and root length as 17.07-18.26% compared to control and able to increase phenolic compounds. The combined application of secondary metabolites from Trichoderma sp. ginger and shallot isolates was the best potential to increase plant height (48.21%), stem diameter (13.72%), fresh weight of plants (21.57%), and fresh weight of root (33.95%). |
