Abstract

The purpose of this study was to determine the utilization of watermelon rind waste as an active ingredient in the manufacture of liquid soap preparations and to obtain the best formulation of watermelon rind extract liquid soap that is physically stable. Watermelon rind waste contains many nutritious substances, such as antioxidants, that are beneficial for skin health but have not been widely utilized. This study utilizes citrulline compounds in watermelon rind, which act as antioxidants and potential vasodilators, to be used as active ingredients in the manufacture of bath soap preparations with the aim of removing dirt and stimulating blood circulation. Research method includes the preparation of thick watermelon rind extract, the preparation of salt solution, and the preparation of liquid soap preparation formulas with varying concentrations of watermelon rind extract. Evaluation includes an organoleptic test, pH, viscosity, foam height, foam stability, homogeneity, and spreadability to obtain a liquid soap formula with stable physical properties. Result showed that watermelon rind extract has the potential to be an active ingredient in liquid soap preparations in order to utilize waste and provide benefits for skin health.

Abstract

This study aimed to evaluate the physicochemical properties and fatty acid methyl ester (FAME) profile of Hermetia illucens (BSF) maggot extract as a potential sustainable ingredient for animal feed. Lipid extraction was performed using a modified Bligh and Dyer method by substituting chloroform with n-hexane to ensure safer and environmentally friendly processing. Proximate analysis revealed that BSF maggots contained 29.36% crude protein, 43.76% crude fat, 9.27% ash, 19.94% crude fiber, and a low moisture content of 3.06%, indicating high nutritional density and storage stability. XRF and qualitative tests confirmed significant mineral content, particularly CaO, K?O, and P?O?, with no detectable heavy metals or harmful contaminants, supporting their safety for feed applications. Microscopic analysis showed particle sizes ranging from 2,000-10,000 nm, classifying the material as a nanostructured biomass. The FAME profile demonstrated a diverse composition dominated by 9-octadecenoic acid (10.92%), triacontane (8.87%), octadecanoic acid (7.65%), and heptacosanoic acid (7.17%). Key medium- and long-chain fatty acids such as dodecanoic acid (C12:0), elaidic acid (C18:1), and stearic acid (C18:0) were also detected, indicating the suitability of BSF lipids as an energy-dense feed component with oxidative stability. Overall, the biochemical and structural characteristics obtained in this study highlight BSF maggots as a promising, nutrient-rich, and environmentally sustainable ingredient for animal feed formulations.
