When addition NPK solution as a nutrition was increased
to 0.4% (P-2), the sugar reduction also increases. During
24 hours incubation, the sugar content reduction is approx
37.5%. The result of fermentation activity is shown in
Figure 5. The treatment of P-3 is almost similar with P-2.
The difference between them is on the starter addition. The
starter for P-3 is increased to 14%. However after 24 hours
of fermentation the reduction of sugar increased slightly.
The reduction of sugar is 43% (see Figure 6).
