Abstract
Pineapple is known to produce waste in form of pineapple skin with total
production of 60% every year. There are four provinces in Indonesia that has the
highest level of pinapple fruit production such as Palembang, Pemalang, Subang
and Sunpride. The phytochemical components of pineapple fruit like
carbohydrate, vitamin, polyphenols and minerals, are also found in pineapple
skin. Therefore it can be used as a source of antioxidant compounds, dietary fiber
and nutrition for microbes, in the making of cider. Cider was made using three
different sugar concentrations of 15, 20 and 25%, then was fermented for 3 days.
Between those four pineapple skin ciders, sugar concentration of 15% was chosen
as the best formulation in cider making, which produced alcohol of 7.56, 7.56,
7.59 and 7.91%; pH of 3.73, 3.64, 3.54 and 3.57; total titratable acidity of 0.54,
0.53, 0.56 and 0.59%; total soluble solid of 9.60, 10.60, 8.37 and 9.93 oBrix.
These results show that cider that was made from Pemalang skin pineapple has
the highest antioxidant activity with IC¬50 of 10753.87 mg/L and phenolic
compounds of 282.13 mg/L. However, the highest dietary fiber was found in
Palembang skin pineapple cider.
