Abstract

ABSTRAK   The development of colored label indicator is increasingly necessary to ensure food safety with a rapid method to evaluating historical real-time of the freshness of the product. The objective of this research is to design labels/film color indicator with natural and synthetic dyes. In this study, the label/film indicators was made of chitosan as a film base and natural dyes of rosella flower, bit fruit and red spinach leaf extract as dyes. This indicator label sware compared with labels made of synthetic dyes. Evaluation the performance of the label in color changes during storage as visual looking was tested  The results showed that natural dyes are very sensitive to temperature, thus it is not appropriate if in the film making, it involves a process that uses high temperatures. Unfortunately, in general, chitosan film typically used a temperature of 70oC to disolve and homogenize the flour of chitosan. Furthermore, natural dyes are also sensitive to acid. As a result, the addition of acetate acid in the chitosan film is undesirable on the filming. Process synthetic dyes provide constant color film. The changing of color in the films with synthetic dyes can be occured due to changes in pH. Therefore, this film/label is very suitable to be applied for products which is decreased in pH if it is deterioration, such as fruits or dairy product.   Keywords : Film/label, color indicator, chitosan, natural dye, synthetic dye

Abstract

ABSTRACT   Currently, the majority of the world’s pulp and paper is manufactured from raw materials, either wood from industrial forest plantations or natural forests. The rate deforestation in Indonesia increases by 2% per year. The study was conducted to combine microbial cellulose of nata de cassava and coconut husk to reduce the use of wood cellulose in manufacturing pulp and paper. Two factors of experiment are the addition of additives and a combination of microbial cellulose and pulp of coconut husk (100:0, 75:25, 50:50 and 25:75). The yields of microbial cellulose and of coconut-husk pulp were consecutively (dry basis) 80.03% and 39.72%.  Physical and strength properties of paper varied, i.e. water content (7.22-10.46%), grammage/basis weight (53.72-68.56 g/m2), tensile index (0.003-0.029 kNm/g), tear index (2.58-16.59 mNm2/g), brightness (8.15-35.1%), printing opacity (45.99-97.08%), and Cobb size60 (46.79-168.17 g/m2 for the smooth/upper surface; and 28.22-183.92 g/m2 for the rough/lower surface). The result of the analysis assuming the conversion of biomass to paper made with 50% pulp of nata de cassava and 50% pulp of coconut husk indicated that the expansion of production of 200 ha can substitute 8,808,356.438 trees per year. With the ammount of this saving trees, 1,233,169.901ton CO2 from the air can be absorbed each year.   Keywords: Nata de cassava, coconut fiber, paper, biomass conversion analysis
