Abstract

Sorgum (Sorgum bicolor L.) is a serelia plant which is potential to becultivated and grown in marginal areas. The advantages of sorghum lie in its extensive agroecological adaptability and resistance to drought. This commodity has a high nutrient content, so it is very good to be used as a source of food and alternative animal feed. Rhizoctonia sp. The cause of root rot is one of the important pathogens in sorghum plants. These pathogens can survive in the soil and can also survive in seeds. Microorganism that developed symbiosis with Zorgum is useful for growth stimulation and biocontrol. The objectives of the researcha re toidentify endofit mushroom that developed symbiosis on some varieties of zorgum and to make an antagonis test on Rhizoctonia sp, the cause of spoiled root disease. This research is conducted in several streas: firstly, take the sample of same varieties of zorgum lokal merah,lokal putih,and numbu in Naiola in Kecamatan Bikomi Selatan while the isolation and identification are held in Faculty of Agrociture of University of Timor and secendly, do antagonist test on Rhizoctonia sp. The study on lokal merah variety has found 7 izolats: Aspergilus sp 1, Aspergilus sp 2, Aspergilus sp 3, Fusarium sp 1, Fusarium sp 2, Trichoderma sp 2. Mushroom endofits found in lokal putih variety are Aspergilus sp.2, Aspergilus sp.3, Fusarium sp.1, dan Trichoderma sp.2. Mushrooms on numbu variety are Fusarium sp. 2, Aspergilus sp.2 dan Trichoderma sp.1. Endofit Mushroom from theroot ofzorgum has 3 genus Aspergilus sp, Fusarium sp dan Trichoderma sp. Trichoderma sp 1 has 20,1 % antagonist character.

Abstract

The fungal-related diseases were responsible as one of many reasons for low production of maize in Indonesia. Controlling fungal contaminants using chemical is hazardous for human nowadays. Thus the need of environmental friendly vegetative-based fungicide such as from the extract of Ampupu tree bark is important. The objective of this study was to investigate the antifungal effect from Ampupu tree bark crude extract in response to growth of Fusarium sp, which responsible as the causal agent of corncob rot. The inhibition test on growth of Fusarium sp. by Ampupu tree bark crude extract was performed with diffusion well method on PDA as media. The process involved the infusion of crude extracts at 1.5%, 3.0% and 4.5% concentration, respectively, into diffusion well on each Petri disk. The result showed that by in vivo treatment, crude extract of Ampupu tree bark with concentration of 1.5%, 3,0% and 4.5%, were able to inhibit the fungal growth of Fusarium miniliforme as the causal agent of corncob rot with diameter of inhibition zone 0.18 mm, 1.85 mm and 2.01 mm, respectively. The higher the concentration of the crude extract given, the larger the diameter of inhibition zone formed.

Abstract

Tujuan penelitian ini adalah untuk mengidentifikasi pengaruh faktor internal dan eksternal terhadap agribisnis jagung di Desa Tualene, Kecamatan Biboki Utara Kabupaten Timor Tengah Utara dan untuk merumuskan strategi perkembangan agribisnis jagung yang tepat untuk dilaksanakan di Desa Tualene Kecamatan Biboki Utara Kabupaten Timor Tengah Utara. Penelitian ini dilaksanakan di Desa Tualene Kecamatan Biboki Utara Kabupaten Timor Tengah Utara secara purposive sampling. Pengambilan sampel dilakukan secara purposive sampling dengan mengambil 80 sampel sebagai responden. Teknik pengumpulan sampel dilakukan melalui wawancara dan metode angket kuesioner. Analisis data menggunakan Matriks SWOT dengan melihat faktor internal (kekuatan dan kelemanhan dan faktor ekstenal (peluang dan ancaman) dan Analisis QSPM (Quantitatif Strategic Planning Matric) dengan mencari strategi alternatif terhadap rumusan strategi yang tepat.  Hasil analisis menunjukkan bahwa strategi pengembangan agribisnis berada pada kuadran I (agresif), di sini potensi agribisnis memiliki kekuatan yang besar dengan memanfaatkan peluang yang ada. Alternatif steategi yang diperoleh Matrics QSPM adalah harus adan dukungan lembaga keuangan dalam bentuk koperasi untuk membantu petani dalam mengembangkan kegiatan usahatani jagung di Desa Tualene, petani harus mencari peluang pasar sesuai kebutuhan konsumen dengan industri dalam bentuk kemitraan dalam pengolahan pakan ternak, peningkatan akses pasar bagi produksi jagung di Desa Tualene
