Abstract

Anthocyanin is pigments are red, purple and blue that commonly found in plants and can be used as a natural dye. One kind of plant that can be extracted as a source of natural dyes and contain anthocyanin is rosella petals flower. The use of solvents and acids are the factors that determine the quality and quantity of anthocyanin that extracted from rosella petals flower. Therefore in this study will be assessed the influence of the use of appropriate solvents and acids in the process of extraction of anthocyanin from rosella petals flower. Types used are varieties rosella sabdariffa. This research was conducted using Randomized Block Design Factorial consisting of 2 factors that is the type of solvent (J) consisting of ethanol and methanol, as well as the second factor which is the type of acid (P) consisting of tartaric acid, citric acid, and acid acetate. Based on the analysis it was found that the anthocyanin pigment (in red) in rosella petals flower is more stable in the acidic conditions (low pH). Type of acid (P) gives a very significant influence (P ≤ 0.01) toward pH values and significant influence (P ≤ 0.05) toward the intensity of the color. Type of solvent (J) that used gives a very significant influence (P ≤ 0.01) toward the intensity of the color, as well as a significant influence (P ≤ 0.05) on yield and levels of anthocyanin

Abstract

Standardization of Working Time at Cocoa Processing Unit, Rimbun Cooperative, Pidie JayaABSTRACT. Rimbun Cooperative is a business unit operating a chocolate factory producing several chocolate products such as cocoa fat, cocoa powder, 3 in 1 instant drinks (sachets), and chocolate bars. This research aims to measure standard times of operators in all working stations of the chocolate factory. These standards comprised the standards in roasting, peeling, pasting, pressing, powdering, powder sieving, powder mixing, dough mixing, refining, and chonching working stations. The data were directly collected using Time Study method with Stop Watch. The samples were randomly selected with five (5) repetitions; and the standard times were measured using Westinghouse Method to quantify performance and allowance factors. The result shows that standard times of operators in each working station are as follows: roasting (36 minutes), peeling (193 minutes), pasting (276 minutes), pressing (78 minutes), powdering (17 minutes), powder sieving (14 minutes), powder mixing (36 minutes), dough mixing (17 minutes), refining (30 minutes), and chonching (30 minutes). In peeling, pasting, powdering, powder sieving working stations, standard times of operators cannot be separated with working times of machines because the operators are required to run the machines (sequence). In general, standard times of operators, after calculation, are larger than direct records because during the working times, operators would not or could not use allowance factors for personal uses, such as for going to bathroom, drinking, and socializing with their colleagues as means to reduce stress or boredom.
