Abstract

This study aims to develop a solid soap formulation using natural ingredients by combining cinnamon (Cinnamomum burmanii) extract and Aloe vera peel extract, which are known for their antibacterial, antioxidant, and moisturizing properties. The research involved several stages, including the extraction of cinnamon and Aloe vera, soap formulation with varying cinnamon and Aloe vera extract concentrations, and testing of physicochemical properties and antibacterial activity against Escherichia coli. The formulated soaps were evaluated for moisture content, free alkali levels, pH, foam stability, antibacterial inhibition zones, and skin irritation. The results showed that increasing the concentrations of cinnamon and Aloe vera peel extracts significantly affected the soap’s characteristics. The optimal formulation was obtained with 15% cinnamon extract and 6% Aloe vera peel extract (A3B3), yielding a moisture content of 2.44%, free alkali content of 1.70%, pH of 11.8, and an antibacterial inhibition zone of 1.28 mm, without any skin irritation. FTIR analysis identified functional groups such as aldehydes, alkanes, aromatics, and hydroxyls, which were associated with the bioactive compounds responsible for antibacterial and moisturizing effects. The presence of cinnamaldehyde in cinnamon and saponins in Aloe vera contributed to the soap’s enhanced antimicrobial and skin-conditioning properties. Furthermore, Fourier-transform infrared spectroscopy (FTIR) analysis identified key functional groups responsible for the soap’s bioactivity. These findings suggest that incorporating herbal extracts into soap formulations can improve their functional benefits, making them a promising alternative for natural skincare products with antibacterial protection and skin health benefits.

Abstract

This study aims to analyze the effects of lime (Citrus aurantifolia) concentration and stirring time on the quality of palm oil-based margarine. The treatments included lime concentrations of 1%, 2%, and 3%, with stirring times of 5 minutes and 10 minutes. The observed parameters included moisture content, fat content, free fatty acid levels, emulsion stability, spread ability, color, texture, aroma, and taste. Analysis of variance (ANOVA) results indicated that lime concentration and stirring time significantly influenced most margarine quality parameters. Increasing lime concentration and stirring time resulted in a rise in moisture content, ranging from 1.7249% to 3.1094%, and an increase in free fatty acid levels from 0.2543% to 0.4195%. Conversely, fat content decreased, ranging from 88.4387% to 81.3954%. Emulsion stability was within 99.6927%–99.8795%, while spread ability varied from 2.6335 g/mm² to 3.6473 g/mm². In terms of organoleptic properties, margarine color showed significant differences, with the highest value of 3.0000 (yellow) observed in the 3% lime concentration with a 5-minute stirring time, and the lowest value of 1.9524 (very yellow) found in the 2% lime concentration with a 10-minute stirring time. Margarine texture varied from firm to slightly firm, with the highest score of 2.6667 recorded for the 1% lime concentration with both 5- and 10-minute stirring times. Aroma intensity increased with higher lime concentrations, with the strongest aroma recorded at 2.9524 in the 3% lime treatment with a 5-minute stirring time. Meanwhile, taste remained mostly neutral, with the highest score of 3.3333 observed in the 2% lime concentration with a 10-minute stirring time. This study highlights that the appropriate combination of lime concentration and stirring time can produce margarine with improved quality characteristics

Abstract

Polystyrene foams populer digunakan sebagai pengemas makanan, namun sulit terdegradasi secara alami, sehingga digantikan dengan pati dan serat yang biodegradable (biofoam). Biofoam dari pati dan serat mempunyai ketahanan terhadap air yang buruk sehingga ditambahkan polyvinil alcohol (PVA). Tujuan penelitian ini adalah menganalisis pengaruh penambahan PVA terhadap karakteritistik biofoam berbasis pati sagu dan ampas tebu yang dibuat dengan menggunakan metode baking process. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan penambahan PVA sebanyak 0, 5,10 dan 15% pada biofoam berbasis sagu dan ampas tebu. Penambahan PVA memengaruhi kadar air, daya serap air, biodegradasi, morfologi permukaan biofoam, warna dan tekstur biofoam, sedangkan aroma tidak dipengaruhi oleh penambahan PVA. Semakin besar penambahan PVA, kadar air dan daya serap air semakin rendah, morfologi permukaan biofoam dan tekstur semakin halus, namun penambahan PVA mengurangi biodegradasi biofoam meskipun masih sesuai dengan standar. Penambahan PVA 15% menghasilkan biofoam dengan kadar air 9,54%, daya serap air 8,11%, biodegradasi 81,34 % selama 7 hari pada tanah gambut, warna putih kecoklatan sampai agak putih, dan tekstur halus sampai sedikit halus.

Abstract

Edible films represent biodegradable food packaging. Potential material used as an edible film is biocellulose nata de coco, but flour made from purple yams needs to be added to increase the solubility of composites in water. The purpose of this research was to study the effects of purple yam flour and glycerol concentrations on moisture, ash content, thickness, barrier properties (WVTR), and mechanical properties biocellulose based edible film. Edible films made with the proportion of slurry biocellulose and purple yam flour were 100: 0; 98: 2; 96: 4% and glycerol were added 0, 1, and 2% and aquades was added to the total volume of 200 ml. The suspension is put in a mould and dried in a 40 ° C oven for 24 hours. Increased concentrations of purple yam flour at biocomposite and glycerol reduce tensile strength and modulus of elasticity, increase the thickness of the edible film. Interaction between biocellulose-purple yam flour and glycerol at high concentrations reduced mechanical strength as a result of network integrity disruption. Interaction between biocellulose-purple yam flour and glycerol reduced moisture content but increased ash content. Glycerol concentrations that were too low and high cause antiplastizicer properties that affected the elongation at break and WVTR edible film. This study demonstrated that proportion of biocellulose-purple yam flour 98:2% and glycerol 1% has good potential for producing the edible films
