Abstract:
The demand for amplang crackers is now increasing. However, the price of its raw material,
mackerel fish, is generally higher compare to other fishes, causing the higher cost of this type crackers
production. Effort to explore other fish as an alternative raw material is required to overcome the
problems. Catfish is one of the choices to be used as raw material since this fish is more available in a
market in a lower price, but the protein properties of this fish is different to mackarel, which will be
possible to affect the nature of the crackers obtained. To produce catfish amplang crackers to be similar
to common amplang product, it is necessary to find out the right composition of catfish and tapioca
flour used. Therefore, the purpose of this research was to characterize physico-chemically and
organoleptically, the catfish amplang crackers made under different ratio of fish flesh and starch. The
experiment was designed using completely randomized design. Physico-chemical data obtained were
analyzed using ANOVA, while the organoleptic test data were examined using chi-square method. The
effectiveness test was carried out to find the proper ratio of raw materials composition used. The results
showed that the higher the ratio of the fish flesh and the starch composition, the lower the texture value
of the crackers as an indication of the decrease of its crispness. Although the lightness of the crackers
was lowered by the addition of more starch to the dough, its linear expansion and hygroscopicity were
not affected. The results of organoleptic test showed that the panelist was prefer to a higher crispness
of crackers. The most preferable cracker was the one with 1:2.25 ratio of catfish flesh and starch,
showing the characteristic of 1.80% moisture, 2.08% ash, 5.75% protein, 23.55% fat, and 66,93%
carbohydrate.
