Abstract

Penelitian     mengarah     pada     evaluasi     kemampuan     dari      pupuk     hayati     kalbar     untuk meningkatkan   produktivitas  dari  tanaman  kedelai.  Percobaan  pada  plot  percobaan  lapangan  di  LIPI Cibinong.  Kacang  kedelai(  Glycine  max )   variasi  Baluran  diperlakukan  dengan  satu rangkaian  pupuk yaitu: Nitrogen berisi kompos mikroba perbaikan, Fosfat berisi kompos mikroba solubilizing, kompos mengandung lignocelullosic menurunkan populasi jamur, Pupuk hayati Kalbar (Kompos memperbaiki kandungan  nitrogem, Fosfat solubilizing  dan lignocellulosic  mengurangi  derajat mikroba), pupuk kimia, kompos  dan  kontrol.  Kenaikan  pupuk    berat  segar  dari  biomass,  angka  dari  daun-daun,  angka  buah polong, dan berat dari biji diamati. Nitrogen, Fosfat dan Karbon yang berada pada tanah sebelum tanaman, saat   fase  generatif   pembungaan   dan   saat   panen.   Hasil   aplikasi   pengujian   pupuk   kalbar   mampu meningkatkan  Karbon  (C  ), Nitrogen  (N  ) dan  Phosphor  (P  ) konten  pada  tanah.  Perlakuan  ini  juga meningkatkan berat segar dari biomass (22%), buah polong (11, 11%) dan berat dari biji (12,22%).

Abstract

Some of soil fungi capable in degrading pesticide deltamethrin, therefore they can be used as fertilizer in organic farming. As a biofertilizer ,fungus also must be able to provide nutrients for plants. The purpose of the study was to obtain fungal isolates that have the ability to decompose pesticides deltamethrin and lignocellulose compounds, dissolved inorganic phosphate compounds and produce growth hormone IAA (Indole Acetic Acid) . The fungal isolates will then be used in the manufacture of bio-fertilizers. Soil samples were put into mineral medium containing deltamethrin, fungus that grew on this medium would then be isolated. The ability of fungus in decomposing deltamethrin was observed using GC. While the ability of fungi to decompose lignocellulose, to dissolve inorganic phosphate compounds and to produce IAA was observed using a spectrophotometer. The results showed that the fungus Aspergillus niger TR1 had the ability to degrade 90.68% of deltamethrin 500 ppm after 1 h incubation and to degrade 0.46% of Poly R - 478 by after 30 min incubation. In addition, this fungus had cellulase activity of 0.029 units/ml and were able to dissolve inorganic phosphate compounds and produce IAA.
