AB  - Problems using straw directly include the contamination of germs on the 
straw from the previous crop.  Alternatives that can be done are giving 
inoculant of biological decomposers The purpose of the research to test 
isolates decomposer in the rate of straw decomposition in soil and to 
test isolates biofertilizer on rice plants in soil treated straw 
compost. Greenhouse experiment was conducted for selecting isolates and 
formulations decomposer consortium and biological agents as well as the 
selection and formulation of biological fertilizers isolates. This 
experiment was consisted of treatments, i.e. incubation time composting 
(1, 2, 3, and 4 weeks) and inoculant (formulation A containing microbes 
T. harzianum, Bacillus subtililis, Cytophaga sp. and Bacillus 
licheniformis; i2 = Formulation B containing microbes B. subtililis, 
Cytophaga sp., and B. licheniformis, Streptomyces sp.) The field 
experiment was conducted to determine the effect of straw compost and 
biofertilizer inoculants (nitrogen fixation bacteria and phosphate 
solubilizing bacteria) on rice. Research at this stage using split plot 
experimental design was repeated three times. The main plot was the 
doses of straw compost + biofertilizer consisting of 8 treatments (0; 
2.5; 5.0; 7.5 t ha-1 without and with biofertilizer 400 g ha-1). The 
subplot was doses of  inorganic fertilizer N, P and K consisting of 5 
levels   (100%, 90%, 80%, 70% and 60% of recommendations dosages). The 
results showed that the A formulation containing T. harzianum, B. 
subtililis, Cytophaga sp. and B. Licheniformis whereas B formulation 
contains B. subtililis, Cytophaga sp., and B. Licheniformis, 
Streptomyces sp. B formulation capable of decomposing straw is better 
than A formulation. Application of straw compost and biofertilizer (5,0 
 t ha-1 + 400 g ha-1) could increase the yield of rice to 13.3%  and  
substitute 20% of inorganic fertilizer (N, P and K).
