Abstract

Carrageenan is a product produced from the extraction process of red seaweed (Rhodophyceae). Carrageenan can be used in various business fields, both in the food and non-food sectors, which function as a gelling additive, binder, emulsifier and stabilizer. The research method used is Literature Review with data collection and screening that has inclusion and exclusion criteria. The results obtained indicate that the quality characteristics and quality for water content and average gel strength have not met the established standards, while the yield value, ash content and average viscosity have met the quality standards set by FAO, FCC and EEC. . The factors that greatly affect the characteristics and quality of carrageenan from seaweed are alkaline concentration, seaweed harvesting age, temperature and extraction time as well as the type and environmental conditions where the seaweed grows.

Abstract

In this study used clay as raw material for making aluminum oxide using sulfuric acid as pelarut.Penelitian also aims to obtain sulfuric acid concentration and reaction time is best, where the variable used is the concentration of sulfuric acid ( 60 % , 70 % and 80 % ) and reaction time ( 40 minutes , 50 minutes and 60 minutes). The results showed that the greater the concentration of sulfuric acid , the levels of aluminum oxide obtained will be greater and greater the heating period , the levels of aluminum oxide obtained will also be greater . Optimum results obtained in 80% sulfuric acid concentration and reaction time 60 minutes.

Abstract

Indonesian people consider the Rubik plant (Calotropis gigantean) is only a wild plants that have no benefits. It is often felled and thrown away. This study was aimed to provide the information the utilized these crops. This research was conducted to determine the ability and characteristics of Rubik stems (Calotropis gigantean) as an addictive substance plasticizer filler, where the rubrik plant was taken at the seaside area of Banda Aceh. Preparation of plasticizers from the filler of this rubric stem was used as an antiseptic and biodegradable plasticizer. The results of FT-IR spectra measurements of the filler plastics of this rubrik plant have a distinct tannin functional group absorption, at 923.850 cm-1 strong buckling numbers were indicated the presence of a potent buckling C-H group due to the presence of the aromatic groups in the tannin compound. For the SEM test, the plasticizer has a porous surface morphology of the outermost layer, this indicates the density of particles smaller than the plasticizer 2 grams of water compared to plasticizer 1 gram of water. The test of biodegradable and Aspergillus Niger fungi on time variations about 10 days were resulted in significant degradation. The rate of degradation with soil was greater than the Aspergillus Niger. Toxicity was used of Escherichia coli bacteria in medium of nutrient agar at 37°C with 48 hours incubation where in plasticizer has antiseptic to Escherichia coli.

Abstract

Bioplastic is one step to reduce the use of plastics that are not environmentally friendly. The genus Metroxxlen, Sp is a bioplastic material that is easily degraded in the soil. Metroxxlen, Sp has a hydrophilic nature which results in its physical properties being low. Bioplastic Starch Genus Metroxxlen, Sp is made by mixing ZnO as a reinforcement, Genus starch Metroxxlen, Sp as a source of natural polymers, with the addition of glycerol as a plasticizer. The results of the spread of ZnO in bioplastics can be seen with SEM. Comparison of ZnO with Genus Metroxxlen Sp. starch 1-3% wt produced a strengthened mechanism characteristic from 0.40 kg/cm2 to 0.70 kgf /cm2; the change in the extension changed down from 120.4% to 99.00%. For glycerol composition with variations from 1-3% wt, the change in elongation changes to increase from 90.00% to 98.00%, the nature of the mechanism changes to decrease from 0.25 kg/cm2 to 0.20 kgf /cm2.
