Effect of Rosella (<em>Hibiscus Sabdariffa</em> Linn) Extract and Surimi Dumbo catfish (<em>Clarias gariepinus</em>) addition on Starch-Based Edible Film-Glycerol Mechanical Properties has been done. The purpose of this study is to create an active environment-friendly packaging material. Surimi additions are intended to improve the mechanical properties of bioplastics and additions of Rosella extract intended as a bio-indicator of acidity. The method used was Solvent Casting. An amount of surimi and rosella extract varied to obtain the best mechanical properties. The results shows that the addition of surimi and rosella flower extract significantly effect the elongation of Edible films produced up to 27%.

Along with the needs of quality preparations, of course the ingredients needed must be good, except  the coloring preparations. Dyes that are widely used in practical activities are synthetic dyes.  However, natural dyes from plants are preferred due to the efficiency in their use while working with the same function. Natural dyes are safer to use even though the degree of stability to heat, light and acidity is uncertain. The purpose of this study was to determine if rosella flower extract (Hibiscus sabdariffa) could be used as a substitute for fuchsin in Gram staining. This research was conducted by the experiments with laboratory scale using in vitro method. The results of the study concluded that rosella flower extract could not be used as natural dye for bacterial staining particularly for Staphylococcus aureus and E.coli bacterial preparations.

Introduction: Rosella is well known as health drink that contains anti bacterial compounds. The purpose of this research is to examine the anti bacterial potential of rosella calyx ethanol extract towards Streptococcus sanguis. Methods: Streptococcus sanguis was obtained from students’ saliva in the clinic of the Faculty of Dentistry, Universitas Padjadjaran. It was cultured in blood agar and incubated for 18 to 24 hours at 37°C in a facultative anaerobic environment. Streptococcus sanguis was isolated based on the characteristics of the colonies formed, Gram staining, inulin and rafinose fermentation tests. The anti bacterial test was performed using agar diffusion method (Kirby Bauer Method) by making agar holes in the agar and filling them with rosella extract with concentrations at 0.20 g/ml, 0.10 g/ml, 0.05 g/ml and 0.025 g/ml. Results: The results of this research show that there was anti bacterial activity from the ethanol extract of rosella calyx with the inhibition zones of 19.85 mm, 12.05 mm, 8.45 mm and 3.65 mm under rosellas’s extract’s concentration of at 0.20 g/ml, 0.10 g/ml, 0.05 g/ml and 0.025 g/ml respectively. Conclusion: The conclusion of this research is rosella calyx ethanol extract has the greatest anti bacterial activity at concentration 0.20 g/ml.

This study aims to determine the physical and chemical characteristics of the edible film of jackfruit seed starch (Artocarpus heterophyllus) added with antioxidant rosella flower extract (Hibiscus sabdariffa). The type of plasticizer used is glycerol. The best treatment in this study was the jackfruit seed edible film with the addition of rosella flower extract 3% (v/v) with the results obtained respectively for a thickness of 0.09 mm, tensile strength 0.003332 N/mm2, elongation percentage 126.36%, elasticity 0.002637 Kgf/mm2, pH 6.122, water absorption 61.67%, solubility 40%, water vapor transmission speed 0.6714 gram/hour m2, FTIR test results show that the process of making edible film in this research is the mixing process Physics, the shelf life of edible film at room temperature is 6 days and at cold temperatures is 8 days, and has antioxidant activity with an IC50 value 219.948 ppm. The addition of rosella flower extract enhances another benefit of edible film which functions as a food protector from the oxidation process (antioxidant).
