Abstract

As a basic human need, the development of textiles still needs to be studied. At first, the textile dyeing process used natural dyes. However, along with the development of technology with the discovery of synthetic dyes for textiles, the use of natural dyes began to be abandoned. Natural color fabrics have many advantages, while promoting disadvantages, such as the appearance of microorganisms on the fabric. To improve the function of the fabric, the addition of antibacterial agent to the fabric is important. This study aims to investigate the optimum condition for producing natural color fabric from Terminalia Belerica’s peel with the application of TiO2 as an antibacterial agent, using the pad dry cure method. The results of the TiO2 coating process on natural dye fabrics are based on its antimicrobial activity. SEM EDX, color strength, and fabric stiffness were also characterized by its physical properties. The analysis results show that the most optimum condition for the stability of color aging was in the 2nd experiment at a concentration of TiO2 at 1%, without curing and sizing of 75%. For stiffness stability analysis, the optimum result was obtained in the third experiment, namely the concentration of TiO2 at 0.5%, with curing and without sizing of 98%. The most influential effects on the antibacterial test include aging, brightness, and stiffness, namely variable sizing with a negative effect. The results of testing antibacterial activity on natural color fabrics of jolawe fruit peel extract applied with TiO2 show that the assessment process caused the fabric to be easily contaminated by bacteria, where the inhibition zone value was 0 mm. The SEM-EDX test did not show any damage to the fabric, and there were grains or lumps on the fabric fibers due to TiO2 coating.

Abstract

Incorporation of omega-3 polyunsaturated acids (n-3 PUFA) into Tuna (Thunnus thynnus) fish oil was investigated by using acidolysis enzimatis Process. The product of this modification is expected to be used as an ingredient nutrifition food products, especially in milk and baby food as well as pregnant and lactating The purpose of this study was to optimizing the used of lipased papaya latex (Carica papaya latex) in the product to incorporation fatty acids rich in omega-3.Bioreactor acidolysis enzematik development and Optimization of process the productivity of fatty acids rich in omega-3. Reaction Acidolysis was conducted between tuna (thunnus thynnus) fish oil by microbial lipase (5% of the weight of the substrate mixture) or vegetable lipased (Carica papaya latex) (6-10% by weight subtract mixture) as biocatalist.Acidolysis mixture the bioreactor at 40 o C for (2-6 hours) and the stirring speed of 200 rpm, pH (4.5 to 6.5). to eliminate free fatty acids from the product acidolysis performed neutralization with NaOH The results are expected to show that the lipase papaya latex (Carica papaya latex) can be used as biocatalyst incorporated omega-3 fatty acids in   tunaIthunnus thunnyl) fish oil . In this study sought conditions for optimum incorporation rate, ie the use of papaya latex lipase concentration of 8%, the ratio of concentrations of omega-3 fatty acid and palm oil (1:1), pH = 5.5, Optimal time of 4 hours and the temperature (40oC) . The results were analyzed incorporation of omega-3 (EPA and DHA) with GC.EPA generated: 3.57% and DHA = 3.91% Key word:Acidolysis,Tuna fish oil
