Abstract

This research was aimed to study the influence of animal age and acetic acid solution concentration on physical and chemical properties. The experiment used Randomized Complete Design (RCD) with two factors and three replicates. The first factor was animal age consisted 3 levels (5, 7 and 9 months). The second factor was concentration of acetic acid solution consisted of 3 levels (2, 4 and 6 percents). The result showed that interaction of animal age period and concentration of acetic acid had no significant effect on gel strength, moisture content, ash content and fat content of pig skin gelatin. It was concluded that pigskin gelatin from ages of 5, 7 and 9 months and concentration acetic acid 2, 4 and 6 % had similar physical and chemical peoperties with the commercial gelatin.

Abstract

This research was aimed to study the influence of animal age and concentration of the acetic acidsolution on physical and chemical properties of pigskin gelatin. The experiment used CompletelyRandomized Design (CRD) with two factors. The first factor was animal age consisted of 3 levels (5, 7and 9 months). The second factor was concentration of acetic acid solution consisted of 3 levels (2, 4and 6 percents). The result showed that animal age had significant effect (P<0.01) on the yields, gelstrength, viscosity, protein content and pH value but interaction of animal age and concentration ofacetic acid had no significant effect (P>0.05) on the yields, gel strength, viscosity, protein content andpH value. It was concluded that pigskin gelatin from ages of 5, 7 and 9 months and acetic acidconcentration of 2, 4 and 6% had similar characteristics to the commercial gelatin, but the optimumproduction of gelatin was combination of pigskin gelatin from 7 months and of 2% acetic acid.

Abstract

in which the first stage aimed to evaluate sodium silica as batik wax releasing agent on chrome leather.Completely randomized design (CRD) was applied in this study. The concentration of sodium silica wastreated as treatments, in which Tl = 0, T2 = 2 g/L, T3: 4 g/L and T4 = 6 g/L. The second stage of thestudy was aimed to evaluate the type of dye used in batik method dyeing on chrome-tanned goat leather.CRD was used and the treatments were types of dye, i.e. T'1 = acid, T'2= indigosol, T'3 = napthol, T'4 =remazol. In both studies, 9 replicates were applied for each treatment. The use of sodium silicateconcentration of 2 g/L resulted in the percentage of release wax of 91.4% and did not degrade the qualityof chrome leather. The type of acid dyes and naphthol provided the best adhesion and color brightnessand resistance to washing treatment, water, sweat, bend, and rub at 4/5 to 5 on a scale of gray. Inconclusion, chrome tanned goat leather with batik dyeing method was recommended to become one ofthe raw materials of leather goods.
