Abstract

Aloe vera is one species of Liliaceae that is able to grow in tropic area such as Indonesia. Aloe verahas potential as food, such as sweets. The slimy and soft texture of Aloe vera makes the problem of producing quality sweets products so it needs soaking with Ca(OH)2 solution.This study aims to determine the content of vitamin C and organoleptic in Aloe vera sweets with various concentrations of Ca(OH)2 solution. The research was conducted in March 2017 at Biology and ChemistryLaboratory,FTIKRaden Fatah State Islamic University. This research use experimental method, through experiment design used RAL one factor with concentration of Ca(OH)2 solution, consist of K1 = 1%, K2 = 2%, K3 = 3% and K4 = 4% (5 repetitions). Research method using titration and hedonic method. The highest vitamin C levels were found in the treatment with the concentration of Ca(OH)2 1% solution ie 323.84 mg/100gr. Organoleptic test results obtained concentration of Ca(OH) 24% solution preferably by panelist.

Abstract

Bacteriophages, or phages, are viruses that can infect and replicate within bacterial cells, such as Escherichia coli. Phages demonstrate a strong ability to lyse host bacteria and exhibit high survivability, making them a promising innovation for use in non-alcoholic antiseptic products, such as hand sanitizer sprays and bacteriophage gels. This study aims to evaluate the effectiveness of bacteriophage-based hand sanitizer sprays and gels in reducing E. coli growth and total microbial colonies on palms, compared to commercial alcohol-based hand sanitizers. The method used in this study is a descriptive quantitative approach using an experimental method, specifically the Hand Sanitizer Spray and Bacteriophage Gel Test as Non-Alcohol Antiseptics. The average total bacterial colonies on male palms for the control treatment, phage gel sanitizer and commercial gel hand sanitizer were 1.95 x 104 CFU/mL; 1.15 x 103 CFU/mL; 2.55 x 103 CFU/mL, respectively,  while on female palms, the values were 2.35 x 104 CFU/mL; 3.05 x 103 CFU/mL; 1.65 x 103 CFU/mL. The average total bacterial colonies on male palms for control treatment, phage sanitizer spray and commercial sanitizer spray were 1.30 x 105 CFU/mL; 2.05 x 103 CFU/mL; 9, 04 x 104 CFU/mL, respectively, while on female palms, the value was 1.58 x 105 CFU/mL; 8.36 x 103 CFU/mL; 8.79 x 104 CFU/mL. The results demonstrated that both bacteriophage hand sanitizer gel and spray significantly reduce bacterial colonies on palms, with phage-based hand sanitizer showing greater efficacy than commercial alcohol-based hand sanitizer.
