Abstract

Cosmetics are needed by the public, such as hand and body lotions and face brightening creams, and there are many misuses of hazardous chemicals in cosmetics, including lotions and face brightening creams. Sodium hypochlorite, a  hazardous chemical, can cause skin damage, such as irritation, rash, hypersensitivity, and burns. The purpose of this study was to determine the presence of sodium hypochlorite compounds and sodium hypochlorite in hand and body lotion cosmetics and face brightening cream. The method used in this research was qualitative analysis with color reaction and quantitative analysis with iodometric titration. The results qualitatively showed that color changes occurred in all samples. NaOCl concentration in hand and body lotion at 0.2% concentration showed an average NaOCl concentration of 3.263 % ± 0.25 and face brightening cream concentration at an average concentration of 10 mg showed NaOCl levels of 88.933 % ± 7.57. Based on this, it was concluded that in the samples of hand and body lotion and face brightening cream, sodium hypochlorite compounds with different levels. Therefore, these samples could have side effects and toxicity in their usefulness as cosmetics. Keywords: Hand & body lotion, face brightening cream, sodium hypochlorite (NaOCl), iodometric titration

Abstract

Antibiotics are drugs used to treat bacterial infections. Irrational use of antibiotics without a doctor's prescription causes antibiotic resistance. West Nusa Tenggara province is ranked sixth with the largest number of antibiotic consumption without a doctor's prescription so the incidence of antibiotic resistance increases. This community service aims to provide antibiotic resistance education to high school students in Selong District. The community service method was carried out at SMAN 1 Selong and SMAN 2 Selong which started with pretest, socialization, and posttest activities to measure students' knowledge of antibiotic resistance before and after socialization. The significance test of changes in students' knowledge levels before and after socialization was conducted using a paired sample t-test. The socialization participants from SMAN 1 Selong and SMAN 2 Selong consisted of 141 high school students in grade XI with an average age of 16. The pretest and posttest data analysis showed that students' knowledge levels regarding antibiotic resistance increased from 41% to 59% at SMAN 1 Selong and 42% to 58% at SMAN 2 Selong after socialization. The average value of students' knowledge about antibiotic resistance increased from 10.04 points to 14.73 points for SMAN 1 Selong and 10.33 points to 14.16 points for SMAN 2 Selong after the socialization was given from a total of 17 maximum points that could be obtained. The results of data analysis using paired sample t-test showed a significant difference (p<0.05) in the average level of student knowledge before and after the socialization activity was carried out. Thus, the antibiotic resistance socialization activity has successfully increased student knowledge in Selong District, especially at SMAN 1 Selong and SMAN 2 Selong effectively.

Abstract

Antioxidants play an active role and are responsible for counteracting free radicals in the body through the process of inhibiting oxidation reactions. Secondary metabolite compounds of phenolic and flavonoid groups are compounds that are widely found in Annona muricata plants that have potential as antioxidants. The purpose of this study was to determine the antioxidant activity of soursop (Annona muricata) leaves using two methods, namely Ferric Reduction Antioxidant Power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH). The extraction method used is maceration method with 70% ethanol solvent, then fractionation using liquid-liquid extraction method, antioxidant test using DPPH and FRAP methods with measurement of levels using UV-Vis spectrophotometry. From the results of maceration, the yield of ethanol extract was 21% from 500 g dry simplisia of soursop leaves and the yield of ethyl acetate fraction was 32.78% from 50 g thick ethanol extract. The results of antioxidant activity test by FRAP method on ethanol extract and ethyl acetate fraction samples were 7.790 and 10.026 mgAAE/g, respectively. Both samples showed very strong antioxidant activity. In DPPH method, ethanol extract showed strong antioxidant activity with IC50 value of 63.947 µg/mL and ethyl acetate fraction showed very strong antioxidant activity with IC50 value of 6.702 µg/mL. From the results, it can be concluded that the ethyl acetate fraction showed very strong antioxidant activity in the DPPH and FRAP test methods, while the ethanol extract showed very strong antioxidant activity in the FRAP test method and strong antioxidant activity in the DPPH test method.
