I received my Bachelor's Degree in 1999 in fishery science and I worked for my thesis on water plants by applying different conditions of shade and open field on duckweed, fertilizing effluent biodigester. After that year 1999 until January 2001, I worked for University of Tropical Agriculture Foundation and responded on farming system; consist of animal, crop and vegetable, and recycling as specification subject.
Year 2001 to 2003 I attended Master course, and did research on plastic tubular film biodigesters with different retention times and loading rates by utilizing pig manure charged to the 500 liters biodigesters liquid volume. As integrated system, it was measured on gas production and fertilizer value in effluent and then linked by utilized effluent to fishponds from effluent biodigesters at different hydraulic retention times.
On this research line I am doing more detail on the dimension of biodigesters and different pig and cattle manure proportions, and link with fish polyculture, and plants.
