Abstract

Gelatin is a protein produced through the partial hydrolysis of collagen and is widely used in the food, pharmaceutical, and cosmetic industries because of its functional properties as a gelling, thickening, and stabilizing agent. Chicken skin has the potential to be developed as an economically valuable alternative source of halal gelatin, but information regarding the effect of ultrasonication temperature on the viscosity of chicken skin gelatin remains limited. This study aimed to evaluate the effect of ultrasonication temperature on the viscosity of gelatin extracted from chicken skin using the Ultrasound-Assisted Extraction (UAE) method. Chicken skin was pretreated using a 2% acetic acid solution and then extracted through ultrasonication at temperatures of 35°C, 45°C, and 55°C for 90 minutes with a material-to-solvent ratio of 1:10 (w/v). The viscosity of the extracted gelatin was measured using an Ostwald viscometer. The results showed that ultrasonication temperature affected the viscosity of chicken skin gelatin. The highest viscosity was obtained at 45°C, namely 3.28 cP, whereas treatments at 35°C and 55°C produced viscosities of 2.36 cP and 1.72 cP, respectively. The increase in viscosity at 45°C indicated that this condition optimized the extraction process without causing excessive degradation of the protein chains. In contrast, ultrasonication at 55°C was presumed to reduce the molecular weight of the gelatin, thereby decreasing its viscosity. This study concluded that an ultrasonication temperature of 45°C was the most suitable condition for producing chicken skin gelatin with better viscosity characteristics. These findings provide a basis for developing a more efficient process for extracting halal gelatin from chicken skin.

Abstract

Residual-waste accumulation and open burning remain problems in areas with limited treatment services. This study reviews 26 sources to assess a simple incinerator concept for Nagari Koto Gadang Anam Koto. Nine studies with original input and residue data reported batch mass or volume reductions of 62.88% to 96.94%. A material-flow evaluation showed that incineration handled 25% to 30% of total waste input within an integrated system. Waste type, moisture, chamber loading, temperature, residence time, air supply, and flue-gas control affected residue and smoke. Smoke colour alone did not demonstrate emission safety. All numerical findings are secondary data, not local measurements. The concept requires waste sorting, trained operators, mass recording, and emission testing before field implementation.

Abstract

Lip balm is a cosmetic product used to maintain moisture and protect the lips from dryness; therefore, the development of formulations using natural ingredients needs to consider the physical and organoleptic characteristics of the preparation. This study aimed to analyze the effect of adding mint leaf extract on the physical and organoleptic characteristics of lip balm based on red guava extract. The study employed an experimental method with three variations in mint leaf extract concentration, namely 2%, 4%, and 8%, while the concentration of red guava extract was maintained at 20%. The observed parameters included organoleptic characteristics, homogeneity, pH, melting point, and spreadability. The results showed that all formulations produced homogeneous preparations with a pink color and semisolid texture. Increasing the concentration of mint leaf extract produced an increasingly dominant mint aroma. All formulations had pH values ranging from 4 to 5, melting points of 50–55°C, and good spreadability. This study showed that the addition of mint leaf extract at concentrations of up to 8% could produce red guava extract-based lip balm with good physical and organoleptic characteristics. These findings provide practical implications for the development of natural ingredient-based lip balm formulations by considering the concentration of mint leaf extract as one of the components influencing the characteristics of the preparation.

Abstract

A ZnO-impregnated activated carbon (AC–ZnO) composite derived from oil palm fronds was successfully synthesized and exhibited high photocatalytic activity toward Congo Red degradation. Congo Red is a persistent azo dye frequently detected in textile wastewater and poses serious environmental and health risks. This study aims to synthesize ZnO-impregnated activated carbon derived from oil palm fronds and to evaluate its photocatalytic performance for Congo Red degradation under UV irradiation. Activated carbon was prepared from oil palm fronds and impregnated with ZnO using a wet impregnation method with ZnO loadings of 5–25% and impregnation times of 6 and 12 h, followed by calcination at 400 °C. The composite materials were characterized by FTIR, XRD, and UV–DRS. Photocatalytic activity was assessed using a 10 ppm Congo Red solution and catalyst dosages of 25–75 mg under UV light. The highest degradation efficiency of 93.87% was achieved using 75 mg AC–ZnO with 15% ZnO loading and 6 h impregnation time. Enhanced performance was attributed to the synergistic effect between adsorption by activated carbon and photocatalytic oxidation by ZnO. The biomass-derived AC–ZnO composite demonstrates strong potential as a sustainable and low-cost photocatalyst for the treatment of dye-contaminated wastewater.

Abstract

Gelatin, a collagen-derived biopolymer, has attracted increasing interest as a sustainable material for advanced engineering applications owing to its biodegradability, biocompatibility, and tunable physicochemical properties. However, understanding of how microwave-assisted extraction (MAE) influences the structural evolution and material characteristics of chicken skin-derived gelatin remains limited. This study investigates the effect of MAE on the physicochemical, structural, and morphological properties of chicken skin gelatin in comparison with conventional waterbath extraction. Gelatin samples were produced under different extraction conditions and characterized in terms of yield, moisture content, ash content, pH, viscosity, Fourier Transform Infrared Spectroscopy (FTIR), UV–Visible spectroscopy, Sodium Dodecyl Sulfate–Polyacrylamide Gel Electrophoresis (SDS-PAGE), and Scanning Electron Microscopy (SEM). The highest gelatin yield obtained by MAE reached 21.19% at 200 W for 10 min, compared with 12.39% obtained by conventional waterbath extraction under the optimum condition. Microwave treatment also produced observable differences in molecular structure and surface morphology compared with conventional extraction. FTIR and UV–Vis analyses indicated changes in molecular organization, while SDS-PAGE suggested broader peptide distribution following microwave treatment. SEM observations revealed a denser and more compact microstructure in the microwave-extracted gelatin. These findings suggest that microwave-assisted extraction may provide an energy-efficient approach for producing chicken skin-derived gelatin while influencing its structural and physicochemical characteristics. The study contributes to understanding the process–structure–property relationship of gelatin biopolymers and provides useful information for future development of sustainable biomaterials and advanced material processing technologies.
