| Judul Artikel | APLIKASI METABOLIT SEKUNDER DUA ISOLAT Trichoderma sp. SECARA TUNGGAL DAN GABUNGAN TERHADAP PENYAKIT ANTRAKNOSA PADA PISANG ULI LEPAS PANEN |
|---|
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui daya hambat metabolit sekunder Trichoderma sp terhadap Colletotrichum musae in vitro, kemampuan metabolit sekunder Trichoderma sp. dalam mengendalikan penyakit antraknosa serta pengaruhnya terhadap mutu buah dan uji organoleptik pada buah pisang. Penelitian dilaksanakan di Laboratorium Perlindungan Tanaman, mulai November 2015 sampai dengan Maret 2016. Pengujian in vitro menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 6 ulangan, sedangkan pengujian in vivo menggunakan Rancangan Acak Kelompok dengan 4 perlakuan dan 6 ulangan. Perlakuan terdiri atas kontrol, metabolit sekunder Trichoderma sp. isolat bawang merah, metabolit sekunder Trichoderma sp. isolat jahe, serta gabungan metabolit sekunder Trichoderma sp. isolat bawang merah dan jahe. Variabel yang diamati yaitu daya hambat antagonis, masa inkubasi, luas serangan, dan intensitas penyakit. Variabel pada mutu buah meliputi kadar gula dan tingkat kekerasan buah. Variabel pada uji organoleptik meliputi tekstur, warna, dan rasa. Hasil penelitian menunjukkan metabolit sekunder Trichoderma sp. isolat bawang merah, jahe dan gabungannya mampu menekan pertumbuhan jamur patogen sebesar 13,70; 12,96 dan 11,48% secara in vitro, sedangkan pada uji in vivo metabolit sekunder Trichoderma sp. isolat bawang merah, jahe dan gabungannya mampu menunda masa inkubasi sebesar 15,55; 14,02 dan 10,49%. Metabolit sekunder Trichoderma sp. isolat bawang merah mampu menekan luas serangan sebesar 15,43%, serta mampu menekan intensitas penyakit sebesar 18,75%. Semua perlakuan tidak berpengaruh terhadap mutu buah pisang lepas panen dan uji organoleptik. |

| Abtrak (Bhs. Inggris) | This research aimed to know the inhibition of secondary metabolites of Trichoderma sp toward Colletotrichum musae in vitro, the ability of the secondary metabolites of Trichoderma sp. in controlling anthracnose and the effect on fruit quality and organoleptic tests on a banana. Research conducted at the Laboratory of Plant Protection, from November 2015 to February 2016. Testing in vitro using Completely Randomized Design with 4 treatments and 6 replications, whereas the in vivo test using a Randomized Block Design with 4 treatments and 6 replications. The treatment consisted of control, secondary metabolites of Trichoderma sp. isolates onion, secondary metabolites of Trichoderma sp. isolates ginger, and a combination of secondary metabolites of Trichoderma sp. isolates onion and ginger. Variables observed that inhibition of the antagonist, the incubation period, attack area, and the intensity of the disease. Variables on the quality of the fruit include sugar levels and the level of violence fruit. Variables in the organoleptic tests include texture, color and flavor. The results showed secondary metabolites of Trichoderma sp. isolates onion, ginger and mix were able to suppress the growth of pathogenic fungi by 13.70; 12.96 and 11.48% in vitro, while in vivo test of secondary metabolites of Trichoderma sp. isolates onion, ginger and mix were able to delay the incubation period amounted to 15.55; 14.02 and 10.49%. Secondary Metabolites of Trichoderma sp. isolates onion able to suppress the broad attacks by 15.43%, and is able to suppress the disease intensity of 18.75%. All treatments had no effect on the quality of bananas off the harvest and organoleptic tests. |
