Laju Pertumbuhan Jamur Rhizopus sp. pada Tempe Kacang Hijau (Phaseolus radiatus L.)
Abstract: This research
was a descriptive
study, which aims
to determine the
rate of growth
of the fungus Rhizopus sp.
the green bean
tempe. This research
was conducted by
growing the fungus
on PDA medium using fungus inoculum of 1 gram of
green beans with tempeh making
dilutions, starting from the dilutions 10-2
, 10-3 and 10-4 are
plated on a
petri dish of
0.1 mL and
incubated for 24
hours. Variation of
time of fermentation used without
fermentation (0 h), 12 hours, 24 hours, 36 hours, 48 hours, 60 hours and 72
hours for each serial dilution. The number of fungi indirectly calculated using
the count method bowls. The results of
this study indicate
that optimum growth
is shown in
36 hours fermentation
time with the
number of colonies on
the 10-2 dilution
of 69 colonies
(6.9 x 103
colonies / g)
and 10-3 dilutions
of the 27
colonies. While the 10-4 dilution only at the time of fermentation 36,
48 and 60 hours of growth of 2 colonies and each colony 1. The longer the
fermentation time decreased the amount of mushrooms.
