Abstract

Pathogenic Escherichia coli infect fruit through irrigation contaminated water. Bacteriophage ϕPT1b has ability to infect E. coli and act as food security. Bacteriophage formulations as emulsion preparations increase the efficiency of application and the stability of long-term storage, one of it is W/O/W emulsions. The objective of this study was to examine the effect of cremophor RH 40, span 80 and their interaction on viscosity, droplet size and inhibition of bacteriophage ϕPT1b W/O/W emulsions against pathogenic E. coli. Factorial design method was used to get the optimum formula. The results showed that the cremophor RH 40, span 80, and their interactions increased the viscosity response, decreased the emulsion droplet size, and increased the inhibition against E. coli. FB is the optimum formula for ϕPT1b W/O/W emulsions which has 1% cremophor RH 40 and 4.5% span 80. The formula produced a viscosity of 29 dPas, an average emulsion droplet diameter size of 10.483, and an inhibition against E. coli of 8.65 m. The desirability index value of 0.905 indicates that FB meets 90.5% of the specified criteria.

Abstract

This study aims to determine how strong the relationship is between leg muscle strength and 100-meter running speed in class XI students at SMA Negeri 3 Gorontalo. The hypothesis in this study is "There is a relationship between leg muscle strength and 100-meter running speed in class XI students at SMA Negeri 3 Gorontalo." The method used in this study is the experimental method, which follows the steps "Pre Test (X1), Treatment (T), and Post Test (X2). The sample determined for this study consisted of 20 class XI students at SMA Negeri 3 Gorontalo, who were selected by Purposive Sampling. The data obtained showed that r count (0.866) was greater than r table (0.444). So, there is a significant relationship between the independent variable and the dependent variable. The data can prove that there is a relationship between leg muscle strength and 100-meter running speed in class XI students at SMA Negeri 3 Gorontalo.

Abstract

Diabetic ulcers are frequently complicated by infections from multidrug-resistant bacteria such as Alcaligenes faecalis, necessitating the development of alternative therapeutic strategies. Bacteriophage therapy presents a promising approach due to its specificity and efficacy against antibiotic-resistant pathogens. This study aimed to formulate and evaluate a bacteriophage-based topical cleanser using the phage ϕAFaV1 for treating A. faecalis infections, focusing on high antibacterial efficacy and low dermal toxicity. Three suspension formulas (F1, F2, F3) were prepared with varying chitosan concentrations (0.5; 0.75, and 1.0%) as a suspending agent. These formulations underwent physical stability testing over 28 days, including assessments of viscosity, pH, zeta potential, and homogeneity. Antibacterial efficacy was determined through inhibition zone assays. All three formulations effectively inhibited bacterial growth, forming clear zones. The F2 formula (0.75% chitosan), containing 200 µL of active phage ingredient, was identified as the optimum formulation. It demonstrated superior physical stability and the most effective bactericidal activity against A. faecalis, as confirmed by statistical analysis. These results indicate that a bacteriophage suspension stabilized with 0.75% chitosan is a highly promising and stable topical agent for combating multidrug-resistant A. faecalis in diabetic wound care.
