Abstract

The quality of dried Bilih fish can be determined on the basis of its water and protein content. The dried Bilih fish produced by Small Medium Enterprise (MSE) Mina Lestari has a high water content of 24% and a low protein content of 35%. These problems were addressed using a proposed parabolic-type drying machine, whose operating system is affected by drying duration, drying tray height, tray rotation, drying layer material and rack quantity and capacity. The results showed that water content decreased to 11.98% and that protein concentration increased to 64.02%. The sensitivity analysis indicated that changes in the values of quality attributes were minimally sensitive to alterations in the weights attached to water and protein content. The optimal combination of factor levels would remain consistent even under a weight of ≤0.83286 ascribed to water content, indicating that a weight ranging from 0 to 0.83286 for this substance exhibits little sensitivity to the initial decision on level factors.
