RESISTENSI BIOKIMIA BIBIT JABON PUTIH (Anthocephalus cadamba (Roxb.) Miq.) TERHADAP Botryodiplodia theobromae Pat. PENYEBAB PENYAKIT MATI PUCUK Lola Adres Yanti; Ahmad Ahmad Ahmad; Nurul Khumaida

Dieback disease on white jabon seedlings is caused by Botryodiplodia theobromaedecreased seedlings quality, economic benefits of nurseries, and seedling death. There is no research for resistance of white jabon to pathogen attacked. This research aimed to study the biochemical resistance of white jabon to B. theobromae attacked. The biochemical resistance was done with studying the chemical compound of white jabon seedlings’ stem used phytochemistry analysis. The results showed that the biochemical resistance before pathogen attacked for white jabon seedlings were found alkaloids, flavonoid, phenol hydroquinone,tannin, saponins, and steroids. After pathogen attacked, the biochemical resistance of white jabon seedlings had the increase in the content of flavonoid, tannin, saponins, triterpenoid and steroids. Keywords: Botryodiplodia theobromae, stem infection methods, the increase of secondary metabolite content, white jabon seedling

PENGARUH VARIETAS KACANG TANAH (Aracis hypogaea L.) DAN DOSIS PENGAPURAN TERHADAP PENYAKIT BUSUK BATANG Sclerotium rolfsii Sacc. PADA LAHAN GAMBUT Chairudin Chairudin; Lola Adres Yanti; Paulina Zalukhu

Peanut has high economic value because has high nutritions especially protein and fat, but the development of broad harvesting and peanut production for the last five years (2008-2012) continues to decrease. The main problem of the peanut low production are disease attacks S. rolfsii and the low broad harvesting. The drop of peanut production in Nusa Tenggara Barat causing harm caused by fungi S.rolfsii can reach 58,3 % per year. Peat is potential land to be developed to farming land. Peat has high acidity so fungi S. rolfsii would be easy to develop and resulted disease severity of peanut disease. Solution of this problem is the gift of lime. This study aims (1) to test the effect of dosages of lime to peanut resistance which was infected by rot stem S. rolfsii on peat land; (2) to study interaction of peanut varieties and dosage of lime to rot stem disease attacks S. rolfsii on peat land. This study used factorial block randomized design 2 x 3 with 3 replications. The studied factors were peanut varieties and the dosage of lime. The result showed that on the effect of varieties, the widest disease percentage was on Takar 2 variety on age 21, 28, 42, and 49 day after planting (DAP) that significant difference with Bison variety. The worth disease intensity was on Takar 2 variety that significant difference with Bison variety (on age 45 and 60 DAP). Key words: dosage of lime, peanut varieties, peat land, the sclerotia of Sclerotium rolfsii

EKSPLORASI DAN IDENTIFIKASI Trichoderma spp. DI UNIVERSITAS TEUKU UMAR Lola Adres Yanti; Miru Ajro Love Frianos

<Trichoderma sp. is land microorganisms which saprophyte and naturally strike pathogens and beneficial for the plant. Trichoderma sp. could hinder the growth of some plant diseases such as Rigidoporus lignosus, Fusarium oxysporum, Rhizoctonia solani, Sclerotium rolfsi. In addition, as the ability to control pathogen, Trichoderma sp. give positive effect on rhizosfer, the growth of plants, and plants production. This research aimed to identifying Trichoderma spp. in University of Teuku Umar. The methodology are exploration, isolation, and macroscopic and microscopic observation. The research showed that the similarity of Trichoderma spp. at FKM, FP, FT, and Rectorat were Trichoderma sp. 1 and Trichoderma sp. 2. On UF of peat and alluvial land only had Trichoderma sp. 1. Keywords: Different location, exploration and identification, Trichoderma spp.

EKSPLORASI DAN IDENTIFIKASI CENDAWAN ANTAGONIS TERHADAP JAMUR AKAR PUTIH (Rigidoporus lignosus) PADA TANAMAN PALA (Myristica fragrans Houtt) Nana Ariska; Lola Adres Yanti; Chairudin Chairudin

Nutmeg (Myristica fragrans Houtt) is a multipurpose plantation commodity crop that almost all parts of the plant have strategic economic value to be cultivated. In Indonesia there are the largest nutmeg commodity centers, including the Maluku islands, North Sulawesi and Aceh. The biggest problem with nutmeg plants is the attack of pests and diseases. One of the most severe diseases in nutmeg is white root mushroom (Rigidoporus lignosus). This study aims to 1) determine the fungus of white root fungus antagonists (Rigodoporus lignosus) from the Aceh nutmeg rhizosphere (Myristica fragrans Houtt), 2) identify the content of antibiotic fungus JAP antagonist compounds in Aceh nutmeg plants. The study was conducted by taking soil samples from nutmeg plants at three nutmeg plantations in South Aceh. The antagonist fungus isolation activity uses a dilution method. Isolation of JAP from infected roots using direct planting method. Furthermore, it is identified macroscopically and microscopically. The antagonist test was carried out using the dual culture method with RAL. From the rhizosphere in the nutmeg area, 5 candidate antagonist isolates were obtained, having high in vitro antagonism ability to the pathogen R. lignosus. Identification results showed that isolates 1, 2 and 3 were Trichoderma spp, and isolates 4 and 5 were Gliocladium virens. Keywords: In vitro, the content of antibiotic compounds, Aceh nutmeg, Rigidoporus lignosus, antagonistic test
