Abstract

Developments in the cosmetics industry, particularly in hair care products, have driven the creation of innovative, natural-based formulations that are safe and environmentally friendly. One of the most popular products is pomade, especially among men. However, many pomades available on the market still contain synthetic ingredients that can cause long-term side effects. This study aims to formulate pomade using natural active ingredients, namely virgin coconut oil (VCO) and aloe vera (Aloe vera L.), and to evaluate the effect of varying the volume of these two ingredients on the physical characteristics and total antioxidant content of the product. VCO was used in volume variations of 0; 5; 10; 15; and 20 ml, while aloe vera was used in variations of 0; 2.5; 5; 7.5; and 10 ml. The parameters tested included pH, melting point, ash content, homogeneity, organoleptic properties, and total antioxidants using the DPPH method. The results showed that the addition of VCO and aloe vera affected the physical properties and antioxidant content of the pomade. The best formula was obtained from a combination of 15 ml of VCO and 10 ml of aloe vera, with a pH of 6.5; melting point of 43°C; ash content of 0.08%; and the highest antioxidant content of 1.5350 mg of vitamin C equivalent per gram. Most samples were homogeneous and organoleptically acceptable, except at the highest concentration, which showed heterogeneity. The combination of VCO and aloe vera proved effective in producing a stable pomade. Keywords: Aloe vera, Antioxidant, Natural cosmetics, Pomade, Virgin coconut oil

Abstract

This study aims to examine the effect of coagulant volume and the addition of corn on the characteristics of tofu. The method used is Central Composite Design (CCD), which is part of the Response Surface Methodology (RSM), along with organoleptic testing to assess consumer acceptance. The raw material variations consist of combinations of soybean and corn in the ratios of 900 g:100 g, 800 g:200 g, 700 g:300 g, 600 g:400 g, and 500 g:500 g, as well as coagulant volumes of ie asam sunti and ie kuloh sira ranging from 100 to 300 ml. The results showed that the best combination was 700 grams of soybean and 300 grams of corn with 250 ml of ie asam sunti, producing a texture of 200 mm/second, pH 5.6, protein content of 5.6%, and a yield of 75%. Meanwhile, 250 ml of ie kuloh sira produced a texture of 240 mm/second, pH 5.8, protein content of 5.8%, and a yield of 75%. Organoleptic testing was conducted using a hedonic scale to determine consumer preference for the resulting tofu. The evaluation covered aroma, taste, and color, which are important indicators of the acceptability of corn tofu products..Keywords: ie asam sunti, ie kuloh sira, soybean, corn tofu

Abstract

Peat water is brown in color, acidic, and contains high levels of organic matter, meaning it does not meet clean water standards. This study used kaolin-based microfiltration ceramic membranes and activated carbon for peat water purification. The membrane composition varied from kaolin (80, 85, 90, 95, 100)% and activated carbon (20, 15, 10, 5, 0)%, sintering at temperatures of 900, 950, 1000, 1050, and 1100°C to determine the effect of composition and sintering temperature on membrane characteristics and filtration performance. Characterization was performed through density, porosity, flux, surface morphology (SEM), and water filtration tests for pH, TDS, and turbidity. The best results were obtained with a membrane composed of 90% kaolin and 10% activated carbon sintered at 1100°C, with a porosity of 40.08%, density of 1.40 g/cm³, flux of 272.38 L/m²·hour, and pore size of 0.56–3.44 µm. Filtration tests showed a 94% reduction in turbidity, an increase in pH from 4.5 to 6.8, and a 41% reduction in TDS. Keywords: Ceramic Membrane, Kaolin, Microfiltration, Peat Water, Sintering
