Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
Abstrak Intensifnya budidaya tanaman lada tidak terlepas dari berbagai gangguan dalam kegiatan produksi. Salah satunya adalah serangan jamur P. capsici Leon. yang mengakibatkan penyakit Busuk Pangkal Batang Lada (BPBL). Penelitian ini bertujuan untuk mengkaji formulasi dan masa simpan T. harzianum dalam menghambat P. Capsici penyebab penyakit busuk pangkal batang lada secara in vitro. Hipotesis yang diajukan adalah formulasi dan masa simpan T. harzianum akan berpengaruh terhadap populasi dan kemampuan antagonistik T. harzianum dalam menghambat jamur patogen P. capsici penyebab penyakit busuk pangkal batang lada secara in vitro. Penelitian ini telah dilaksanakan di Laboratorium Penyakit Tanaman, Jurusan Proteksi Tanaman, Fakultas Pertanian, Universitas Lampung pada bulan Agustus sampai Desember 2009. Perlakuan terdiri dari masa simpan (2, 4, 6, 8, 10, 12 minggu) dan perlakuan formulasi (Pelet, Cair, Serbuk). Perlakuan disusun secara faktorial dalam rancangan acak lengkap dengan tiga ulangan. Data yang diperoleh dianalisis dengan sidik ragam dan dilanjutkan dengan Uji BNT pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa (1) formulasi dan masa simpan berpengaruh nyata terhadap populasi dan aktifitas antagonistik T. harzianum dalam menghambat P. capsici secara in vitro, namun interaksi antara keduanya tidak nyata, (2) pada perlakuan formulasi, populasi T. harzianum tertinggi terdapat pada formulasi cair (5,56 x 103 cfu) dan pada perlakuan masa simpan, kepadatan populasi T. harzianum tertinggi pada masa simpan 8 minggu (5,56 x 103 cfu), dan (3) kemampuan antagnositik T. harzianum paling baik terdapat pada formulasi cair dengan kemampuan antagonistik tertinggi (64,89%), kemudian formulasi serbuk (51,11%), dan tidak ada aktifitas antagonistik pada formulasi pelet (0%) setelah masa simpan 12 minggu. Kata Kunci: lada, P. capsici, formulasi dan masa simpan T. harzianum. Abstract Intensive cultivation of pepper plants could not be separated from the various disturbances in production activities. Among the various disturbance were a fungus attack of P. capsici Leon. that causes basal stem rot disease (BPBL). This research aimed to evaluate the formulation and saving period of T. harzianum in inhibiting P. capsici the causal agent of stem rot disease of pepper in vitro. The hypothesis of the study were the formulation and saving period of T. harzianum will affect the population and antagonistic activity of T. harzianum in inhibiting the pathogenic fungi P. capsici the causal agent of stem rot disease of pepper in vitro.This research was conducted in the Plant Pathology Laboratory, Department of Plant Protection, Faculty of Agriculture, Lampung University on August to December 2009. Treatments consisted of saving period (2, 4, 6, 8, 10, 12 weeks) and formulations treatment (Pellets, Liquid, Powder). The factorial experiment was arranged in completely randomized design with three replications. Data were analyzed with ANOVA followed by LSD test at 5% significance level. The result showed that (1) formulation and saving period significantly affected the population and antagonistic activity of T. harzianum in inhibiting P. capsici by in vitro, but the interaction between them is not real, (2) in the treatment of formulation, the highest populaton of T. harzianum contained in liquid formulations (5.56 x 103 cfu) and in the saving period treatment, the highest population density of T. harzianum were in 8 week of saving period (5.56 x 103 cfu), and (3) the best antagonistic ability of T. harzianum were showed in liquid formulation with the highest antagonistic ability (64.89%), then the powder formulation of T. harzianum (51.11%), and no antagonistic activity on the formulation of pellets (0%) after 12 weeks of saving period. Keywords: pepper, P. capsici, saving period, and formulation T. harzianum.
