A. Feedstock
The tapping from fruit of Arenga pinnata palm that
produces the sap is a good substance for alcohol
fermentation due to its high sugar and low ash contents.
The sugar content of Arenga pinnata palm is capable as
feedstock for alcohol fermentation. The content of sugar is
almost 60%. The total sugar is dominated by sucrose and
glucose compounds. During process fermentation, the
sugar was converted to alcohol compounds by microbial
activities. The characteristic of the sap is acid with pH
value is approx 4 (see Table 2).
