Abstract

The study was aimed to improve the physical characteristics of culled duck meat using marinationin ginger extract and aging. The material used were Magelang culled ducks (2.5 years old). Gingerextract was derived from the rhizome of fresh ginger (Zingiber officinale Roscoe). The experimentalused was a factorial design (3x3), with two main factors, namely the concentration of ginger extract andaging time in completely randomized design. Level of ginger extract concentrations were 0, 5, 10% andlong times of aging were 24, 48, 72 hours as combination treatments, and replication for each treatmentwere 3 times. There was a significant interaction between the factors of aging time with ginger extractconcentration in influencing moisture, pH , hardness and the water holding capacity of culled Magelangduck meat. The best treatment to improve the physical characteristics of culled duck meat weremarination in 5% ginger extract and aging for 48 hours.

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.
