Local Microorganism From “Tape” (Fermented Cassava) In Composition and Its Effect on Physical, Chemical And Biological Quality in Environmental
2020
The purpose of this study is to identify the potential of microbes, physical,
chemical, biological qualities. Local Microorganism Solution (MOL) from tape
(Fermented Cassava) as composting bio-activator and physical, chemical, biological
quality. Compost based on concentration and fermentation time. The design of this
study used true experiments with factorial patterns of randomized block designs. The
first factor was tape (Fermented Cassava) concentration which consisted of 100
grams; 150 gram; and 250 grams. The second factor was the fermentation time
consists of 10 days and 20 days. The parameters observed were: biological, physical
and chemical quality of local microorganisms and compost. Physical quality included,
temperature, color and odor, biological quality which included the total population of
bacteria and fungi. Chemical quality included pH, total-N content, total-P, K, Corganic
and
C
/
N
ratio.
Data
were
analyzed
using
ANOVA.
The
results
of
this
study
indicated
that the microorganism of the mole solution of tape (Fermented Cassava)
was Saccharomyces sp. as much as 9.6 x 105. The highest total bacterial population in
the tape (Fermented Cassava) treatment was with a concentration of 250 grams for 20
days, while compost was found in the treatment of 250 grams for 20 days, which is
1x102. The highest degree of acidity in the same mole and compost solution is found
in the treatment of 250 grams for 20 days. The results of this study fermentation
process occur due to microbial activity, especially bacteria in remodeling the
ingredients contained in MOL solution. Changes that occur in the fermentation
process include changes in color and odor. For chemical changes showed that the best
solution quality for Mol solutions is (N-total 0.99%), (P-0.33 mg kg-1), (K 0.71), (Corganic
7.56),
(C
/
N
12),
meanwhile
for
compost
(N-total
0.38%),
(P-0.20
mg
kg-1),
(K
0.208),
(C-organic
7.50),
(C
/
N
35).
