Abstract

Polysaccharides such as carrageenan are potential materials that can be used as bioplastics. Modified starch is a material that can reduce the hydrophilic properties and increase the hydrophobic and mechanical properties of bioplastics. The purpose of this study was to determine the effect of the application of modified starch on carrageenan-based bioplastic spoons from seaweed Eucheuma cottonii on the biodegradability and water resistance, and to determine the best formulation of bioplastic spoons that could produce the best biodegradability and water resistance. The experimental method in this study used a completely randomized design. The treatment given was the concentration of modified starch (0; 2; 2.5; and 3 grams). The results showed that the addition of modified starch would slow down the rate of biodegradation and improve water resistance, but produced fluctuating values caused by various factors.

Abstract

Anadara granosa are one of the benthic organisms that are frequently reported because contained heavy metals because of water pollution. This is because A. granosa is a feeder filter so that accumulates heavy metals in its body. Reduce the levels of heavy metals with activated charcoal from coconut shells in the absorbance process using the depuration method. It is re-optimized with the use of nano-active charcoal. The goal was to determine the effect of concentrations of nano-active charcoal from coconut shells on the heavy metal content of A. granosa. Stages of this reserch, namely charcoal activation, ultrasonication, SEM testing, blood shell depuration, and heavy metal testing. Based on the results of the Scanning Electron Microscope (SEM) Test it is known that the charcoal particles are sized 10-9 nm. The types of heavy metals found included hydrargyrum (Hg) 0.0009 mg/kg, cadmium (Cd) 0.62 mg/kg, and plumbum (Pb) 1.82 mg/kg. Heavy metals with lowest content is found in P5 (active charcoal concentration of 15% of the sample weight) of mercury (Hg) 0.0002 mg/kg; cadmium (Cd) 0.1 mg/kg; and lead (Pb) 0.373 mg/kg. This shows that the higher concentraion of activated charcoal given, the lower heavy metal content.

Abstract

Green mussels is one of Indonesia's fisheries commodities that has a high export value. The high export activity of shellfish products will have an impact on the environment due to shell waste produced. Utilization of shell shell waste is a solution to overcome environmental pollution and can be in the form of diversification of food products that can be used as raw materials for food flavorings. Making a food flavor or natural flavor requires an emulsifier. One ingredient that can be used as an emulsifier is cornstarch. The purpose of this study was to determine the effect of adding cornstarch to the chemical characteristics of the green mussel paste flavor. This study used a Completely Randomized Design (CRD) consisting of 5 treatments with cornstarch concentration of 0%, 2.5%, 5%, 7.5%, and 10% with 4 replications. Protein and fat content are the main components of making flavors. The main parameters used in this study are flavor paste with emulsifier having proximate levels (protein, water content, and fat content) and supporting parameters are yield, VRS levels, water solubility, and pH levels. The results of this study indicate that the addition of gelatin has a significant effect (P <0.05) on the chemical characteristics of protein, fat, water content, yield, water solubility, VRS, and pH. Pasta flavor with a concentration of 10% has good levels of protein, fat, water content, yield value, water solubility , and VRS.

Abstract

Polysaccharides from carrageenan have potential as bioplastics that is resistance to waters (hydrophobic), alsocan be improved by using modified starch. Modified starch is a material that can reduce the hydrophilic properties of bioplastics. The objectives of this study were to determine the effect of modified starch application on carrageenan-based bioplastic’s cup on biodegradability and water resistance and to determine the best bioplastic formulation for biodegradability and water resistance. This study was conducted using experimental methods in the biodegradation test and the resistance or swelling test. The experimental method in this study used a completely randomized design (CRD) at a significance level of 5% (α = 0.05). The results of this study indicate that the addition of high modified starch can increase the water resistance of bioplastics but the addition of high modified starch will result in slower biodegradability.

Abstract

The use of seaweed (Eucheuma spinosum) as a source of bioactive ingredients from algae has not been widely carried out, even though it has secondary metabolites that are thought to have antibacterial activity. The purpose of this study was to determine the inhibitory activity of the crude extract of red algae E. spinosum on the growth of Staphyloccus epidermidis bacteria in vitro. The working method used is an experimental and qualitative research design. Extraction of E. spinosum used maceration with 96% ethanol solvent and evaporated using a rotary evaporator to obtain a crude extract yield of 1.54%. The phytochemical screening test used thin layer chromatography and precipitation tests. The results of phytochemical screening showed that crude extract of Eucheuma spinosum contained alkaloids, flavonoids, terpenoids and saponins. These compounds are thought to have the potential to have antibacterial activity. The antibacterial test was based on a comparative study of the literature using the disc diffusion method (Kirby-Bauer test) with a positive control of Clindamycin 10μl/ml and a negative control of distilled water. Comparison of the literature on the results of the antibacterial activity test is thought to be effective for treating acne-causing bacteria, namely Staphylococcus epidermidis with an average inhibition of 26.5 mm (30 μl). The antibacterial activity is because seaweed contains secondary metabolites such as flavonoids, alkaloids, terpenoids, and saponins. The need for herbal therapy to treat diseases caused by Staphylococcus epidermidis bacteria to reduce bacterial resistance to antibiotics.
