Abstract

Kepok banana peel contains tannin as antibacterial activity and saponin acts like a surfactant. Detergent is a cleaning agent commonly used by the community. Banana peel is extracted with ethanol solvent to produce antibacterial activity and can be used as a bioadditive. Knowing the antibacterial activity, the extract requires incubation. Because the nature of saponin is the same as surfactant, banana peel extract can be compared with mes surfactant to make liquid detergent. This study was conducted to identify tannin and saponin in banana peel extract, obtain the best banana peel extract yield with the best solvent concentration and the best incubation time for bacterial inhibition, and the best formulation with the addition of extract to the liquid detergent application. The banana peel extraction process with ethanol uses the Ultrasonic Bath Extraction method. The independent variables in this study were the concentration of extraction solvent (50%, 60%, 70%, 80% and 96%) and the formulation of adding banana peel extract (0%, 5%, 10%, 15% and 20%). The best extraction results were obtained with a solvent concentration of 96% which produced a brown liquid with a strong aroma containing tannins and saponins with the best yield of 11.27% and the best antibacterial activity test with a time of 72 hours, then the extract was made into a liquid detergent formulation as a surfactant and compared with MES surfactant so that the best formulation was obtained in formulation F2 (5% banana peel extract 15% methyl ester sulfonate surfactant) and formulation F3 (10% banana peel extract 10% methyl ester sulfonate surfactant).

Abstract

Kasumba turate (Carthamus tinctorius Linn) or safflower is a traditional medicine used by South Sulawesians. Polyphenol compounds and antioxidant activity are active components of kasumbu turate. This component can be obtained through extraction. The goal of this study was to find the best conditions for extracting kasumba turate with high total phenol levels and strong antioxidant activity, as well as encapsulating the resulting extract. The ultrasonic assisted extraction (UAE) method was used to extract Kasumba turate with methanol, and the Responses surface Methodology method was used to optimize the extraction. Behnken Box Variations in composition solutions of 50, 60, 70, 80, and 90%, as well as time variations of 20, 30, 40, 50, and 60 minutes. A solvent ratio of was used for sample extraction 1: 1 using Methanol solvent and water, determined which is the best result of this variable, and continued by analyzing is a test analysis with Spectrophotometry, DPPH, and the best results of the variable are analyzed using Spectofotometry to see the content of flavonoid compounds in Kasumba Turate Flowers.

Abstract

Chicken eggshells, commonly discarded as household and industrial waste, present a valuable opportunity for sustainable use due to their abundant quantity. This study explores the potential of utilizing chicken eggshells as a natural protein source to create eco-friendly skincare products, particularly peel-off gel masks, which can combat free radicals and enhance skin elasticity and moisture. The research focused on determining the optimal conditions for protein extraction from chicken eggshells using acetic acid solvent and varying extraction times. Response Surface Methodology (RSM) was employed to optimize these conditions. The protein extraction process involved testing the extracted protein for biuret reaction using spectrophotometry, determining protein content with Ultra Performance Liquid Chromatography (UPLC), and evaluating the physical properties of the resulting peel-off gel mask. The results indicated that both solvent concentration and extraction time significantly impact the yield of protein. The optimal conditions were found to be an acetic acid concentration of 0.5 M and an extraction time of 24 hours, which produced a yield of 5.064%. The RSM model validation showed a p-value 0.05, a desirability index of 0.887, and a predicted yield of 3.080%, with a deviation of 1.98% from the actual yield. These findings suggest that the model is accurate and reliable for further development of the peel-off gel mask. This approach not only provides a sustainable use for eggshell waste but also contributes to the development of high-quality, natural skincare products.
