ABSTRAK
Biology reductions of coffee residue, waste
from PT. Torabika industry, Tangerang using earthworm have been carried
out. The aim of experiment is to know the ability of earthworm to
decompose the waste become verrnicompost and to evaluate it quality. The
experiment was used earthworms Eisenia foetida species and 25 - 75 % of
cow manure as a medium mixture. The result showed that the structure of
vermicomost is soft andblack colors with cation capacity is 17.49 -
21.32 megll00. The mineral content were determined using X-ray
Fluorescence Spectrometer (XRF), UV-Vis Spectrophotometer and Kjeldahl,
the result showed that the concentrations of N are 0.93 - 0.94 %, CI N
11.26 - 15, K 6.64 - 6.95 %, Ca 12.1 - 17.3 %, P 0.09 - 0.16 %, Mn 0.11 -
0.19 %, Fe 2,01 - 2,69 %, Zn 538 - 779 mgl kg. The earthworm biomass
was increased until thirdweeks of vermicomposting.
