Abstract

This study aimed to evaluate the antioxidant activity of collagen extracted from catfish (Clarias sp.) using DPPH and ABTS assays. The research procedures included sample preparation, collagen extraction using an acid-based method, and antioxidant analysis at concentrations ranging from 20–100 ppm. The degree of hydrolysis (DH) was measured to determine the effectiveness of Alkalase in producing bioactive peptides. The results showed that higher enzyme concentrations led to increased DH, with the highest value of 62.42% obtained at 3% Alkalase. Antioxidant activity increased with sample concentration, with maximum inhibition values of 78.57% (DPPH) and 85.00% (ABTS) at 100 ppm. The ABTS assay exhibited higher sensitivity than DPPH. These findings indicate that catfish collagen has strong potential as a safe and natural antioxidant source suitable for further development in food, pharmaceutical, and cosmetic applications.

Abstract

Lavender flowers are widely used in aromatherapy because their principal constituents, linalyl acetate and linalool, are associated with relaxing effects. Aromatherapy preparations contain volatile aromatic substances intended to promote calmness and relaxation. This study aimed to formulate and physically evaluate aromatherapy candles containing lavender (Lavandula angustifolia) essential oil. An experimental laboratory design was employed, with lavender essential oil as the active ingredient and variations in beeswax and stearic acid concentrations. Formula I contained 50% soy wax, 50% beeswax, and 25% stearic acid, whereas Formula II contained 50% soy wax, 60% beeswax, and 30% stearic acid. The formulations were evaluated for organoleptic characteristics, burning performance, melting point, and hedonic acceptance. Both formulations met the specified physical-evaluation criteria, demonstrating that lavender essential oil can be successfully incorporated into aromatherapy candle formulations

Abstract

Nanoemulsions are nanometer-scale dispersion systems used as bases for pharmaceutical and cosmetic preparations because they can improve the solubilization and physical stability of lipophilic ingredients. This study evaluated the physical stability of a grape seed oil nanoemulsion base containing Tween 80, PEG 400, Poloxamer 407, and Transcutol HP using an accelerated centrifugation test. Four formulations with different surfactant and co-surfactant concentrations were prepared and centrifuged at 2,000, 4,000, 6,000, and 8,000 rpm. Homogeneity, clarity, turbidity, and phase separation were assessed visually after each treatment. All formulations remained homogeneous without visible phase separation at 2,000 and 4,000 rpm. At 6,000 rpm, several formulations showed increased turbidity but no phase separation. At 8,000 rpm, the formulations remained homogeneous and showed no visible phase separation. The stability of the system may be associated with Tween 80 reducing interfacial tension, PEG 400 and Transcutol HP supporting solubilization of the oil phase, and Poloxamer 407 providing steric stabilization. These results demonstrate satisfactory physical stability under the applied centrifugation conditions and support further evaluation through droplet-size analysis, polydispersity index, zeta potential, rheology, and long-term storage studies.

Abstract

Bromelain is a proteolytic enzyme derived from pineapple (Ananas comosus) and has potential as an active ingredient in topical preparations. The development of bromelain in gel form requires a suitable base to produce a preparation with good physical characteristics and stability. Hydroxypropyl methylcellulose (HPMC) was selected as the gel base because it can form a stable, homogeneous gel suitable for topical use. This study aimed to formulate and evaluate the physical characteristics and stability of an HPMC-based bromelain enzyme gel preparation. The study was conducted experimentally by optimizing HPMC gel bases at concentrations of 1%, 2%, and 3%. The selected base was used to prepare bromelain enzyme gel with bromelain concentrations of 2% (F1), 4% (F2), and 8% (F3). The evaluation included organoleptic properties, homogeneity, pH, viscosity, spreadability, adhesiveness, qualitative identification of bromelain, and stability using the temperature stress test method. The optimization results showed that 2% HPMC was the most suitable base, as it produced a homogeneous gel with pH, viscosity, spreadability, and adhesiveness values that met the requirements. The Biuret test was positive in pure bromelain and all gel formulas, indicating that bromelain protein remained detectable after formulation. Physical evaluation showed that all formulas were homogeneous, had a characteristic bromelain odor, and met the requirements for pH, viscosity, spreadability, and adhesiveness. The stability test showed no noticeable organoleptic changes in all formulas. However, pH and viscosity decreased as temperature increased, with the greatest viscosity reduction observed in F3. Based on the results, the HPMC-based bromelain enzyme gel preparation showed good physical characteristics, with 2% HPMC as the most suitable gel base. However, storage temperature should be considered to maintain the physical stability of the preparation.

Abstract

Air is the most critical factor for human survival, which must and must always be maintained for quality. If the air quality changes from normal, the air has been polluted. Transportation activities are one of the contributing factors to air pollution. UNG is one of the largest campuses in Gorontalo Province, which involves students in increasing the number of residents outside the area who have an impact on campus activities and an increase in the number of vehicles. In the UNG area, street vendors sell from 6 in the morning to midnight. This makes street vendors a group at risk of experiencing health problems due to exposure to NO2 from vehicle exhaust emissions. This type of research is observational with a descriptive study design. This research was conducted on Jalan Jendral Sudirman, around the UNG campus. The population in this study were all street vendors selling around the UNG campus, totaling 58 traders. The sampling technique uses the Total Sampling technique; the entire population is used as a sample. The results showed that the average concentration of NO2 around the UNG campus did not exceed the quality standards set by Government Regulation No. 22 of 2021, namely 0.2 mg/m3, and the most common health complaints experienced by respondents were coughing 43 people (74.1%), body aches and headaches 36 people (62.1%), runny nose 32 people (55.2%), sore throat 12 people (20.7%). Moreover, the least experienced was eye irritation in 2 people (3.4%). It is suggested that there should be monitoring of pollutant concentrations, and it is hoped that street vendors will use masks when selling and reduce selling time.
