Abstract

The schools have been allowed for doing face-to-face learning process with many requirements.Making own hand sanitizer will help schools to keep applying health protocol beside washing hands. Essential oils have been trusted for a long time give a calm effect and reduce stres. This activity have purpose to assistance hand sanitizer production with essential oils fragrance at SMP Muhammadiyah 1 Prambanan Yogyakarta. Knowledge have been transfered by team followed with demo and training to produce hand sanitizer with lemongrass fragrance at first activity. Knowledge score was determined from pre-test and post test answer score from multiple choice questions about hand sanitizer. Follow up became the next activity to ensure school can make their own hand sanitizer independently. The result showed knowledge score was increased from 52,11 to 92,11. School also have been made hand sanitizer independently with another essential oil varians. This products were limited used for school. Communication between team and school still continues.

Abstract

Parijoto (Medinilla speciosa, Reinw. ex. Bl.), a tropical plant native to Southeast Asia, contains flavonoids, tannins, and saponins, which have the potential as an anticancer. Gold nanoparticle-based drug formulations are applied to increase the anticancer effectiveness of herbal medicines. The compounds in the stalk of parijoto have the potential to be bioreductor in the biosynthesis of gold nanoparticles. This study aims to determine the physicochemical characterization, cytotoxic activity, and expression of protein caspase-9 after treatment with nanogold parijoto (AuNPs-PR) on HeLa cell. The nanogold biosynthesis process was done by reacting 1 mM HAuCl4 with parijoto aqueous extract (EP). Physicochemical characterization measure of particle size, Polydisperse Index (PdI), and zeta potential of AuNPs-PR was carried out using a particle size analyzer. The cytotoxic effect and viability cell of AuNPs- PR were carried out using the MTT assay. The expression of caspase-9 was observed by immunocytochemistry assay. Physicochemical characterization of AuNPs-PR shows that the particle size value is 160.8 nm with PdI and zeta potential values of 0.430 and -4.56 mV respectively. In the MTT assay, both AuNPs-PR and EP demonstrated a reduction in the viability of Hela cells after 24 h in a dose-dependent manner, yielding IC50 values of 3.28 μg/mL and 19.22 μg/mL, respectively. AuNPs-PR and EP showed low cytotoxic activity against Vero normal cells, with IC50 values of over 500 μM. Further, the immunocytochemistry assay indicated that there was upregulation of caspase-9 by their expression. These results indicate that AuNPs-PR could effectively induce apoptosis in HeLa cells by upregulating caspase-9.Keywords: caspase-9, HeLa cells, MTT, nanogold, parijoto.

Abstract

One of the effective ways to stay healthy is maintaining cleanliness, including hand hygiene. Various diseases can be easily transmitted through the hands. However, modern developments have changed the habit of handwashing with water to using hand antiseptics. Hand sanitizer is an alternative to overcome this problem. Unfortunately, some hand sanitizer gels on the market still contain alcohol as an antibacterial ingredient. It is necessary to innovate in making hand sanitizers using non-alcoholic ingredients as antibacterials, for example, natural ingredients like garlic. Garlic contains allicin that functions as an antibacterial. Meanwhile, VCO contains high lauric acid with antibiotic properties that function as antiviral, antibacterial, and antiprotozoal. It also contains capric acid, with antiviral and antibacterial functions. This study aims to examine the effect of concentration variation of VCO on the physical stability of garlic extract emulgel preparation and antibacterial effectiveness against the growth of Staphylococcus aureus. The concentration variation of VCO in this study was 3%, 5%, and 7% for 3 types of formulas. The results showed that the concentration variation of VCO in emulgel preparations gave differences in the physical properties of the gel, including pH, viscosity, adhesive strength, and spreadability. It can be concluded that the higher the VCO concentration, the higher the pH, viscosity, and adhesive power, and the lower the spreadability and antibacterial inhibition power against Staphylococcus aureus. The best result from the evaluation of physicochemical properties and antibacterial tests was Formula 1, although it was still in the weak inhibitory power category.
