DESAIN EKSPERIMEN TAGUCHI UNTUK MENINGKATKAN KUALITAS PUPUK ORGANIK BERBAHAN BAKU KOTORAN KELINCI
Abstract: Currently one
of the organic
fertilizer started being
used is organic
fertilizer from rabbit
feces. In Pesanggrahan Batu
area, there are
about 25 farmers
in each farmer
has about 50
rabbits and joinning
to "Paguyupan Ternak Karya
Bagus". The problem
is there still
no standard composition
of optimal organic fertilizer made
from rabbit feces, so it is
necessary to do a research to evaluate the composition of the organic
fertilizer made from rabbit feces to get the
high content of
nitrogen, phosphorus and
Kalium. Some factors
used in this
research related to
the raw material
for organic fertilizer are
rabbit feces, bran,
husk and probiotics
factor with 3
levels of each
factor, so then
we select experiment with orthogonal array 34 and 9
variations. The chosen orthogonal array table must have a minimum number of raw which is not less than the total number of
degrees of freedom- in this research the total degrees of freedom is 8. Then do
experiment in laboratory to check nitrogen (N), phosphorus (P) and kalium (K)
content in the soil chemistry laboratory UB
faculty of agriculture.
Based on data
analysis we get
the combination of
the level of
high N content
is by using
a composition of 3000 g rabbit feces, EM4 10 ml and the amount of chaff
200 gr. The combination of the level that has the effect of generating a high
phosphorus content value is the amount of rabbit feces at the level of 3000 g,
the amount of EM4 at the level of 20 ml and the amount of chaff at the level of
400 g and level combination that has the effect of generating a high kalium
content value is the amount of rabbit feces on level of 3000 g, the amount of
rice bran at a level of 200 g, the amount of chaff at the level of 400 grams
and the amount of EM4 on the level of 20 ml.
