Pengaruh Jarak Pisau Atas Pisau Bawah dan Diameter Pinang Muda terhadap Kualitas Hasil Pengupasan

Abstract

The aim of this research was to find the effect of young areca fruit diameter and distance of upper and under knifs quality of peeled product. The research had been performed using completely randomized design with two factors i-e : diameter of areca fruit (D1= <3,50 cm ; D2 = 3,50 – 3,60 cm; D3 = <3,60 – 3,70; D4 = <3,70 cm) and the distance of upper and under knifes (P1 = 1,5 cm; P2 = 1,7 cm; D3 = 1,9 cm; P4 = 2,1 cm). Parameters analyzed were machine capacity , percentage of peeled fruit, percentage of nut on the peel, percentage of loosed nut percentage of fruit unpeeled, percentage of intact nut, percentage of defect areca nut. The result showed that the fruit diameter had significant effect on all parameters except the percentages of deffect nut and intact nut . The distance of upper and under knifes had highly significant effect on all parameters except percentage of nut on the peel, percentage of loosed nut which were significantly diffect. The interaction of diameter of young areca fruit anf distance of upper and under knifes had highly significant effect on all parameters except machine capacity which were significantly diffect. The best result for young areca fruit diameters was on D4 = (> 3,70 cm) and the distance between upper and under knifes J3 = (1,9 cm).
