Abstract

The growth of micro-organisms that acquire resistance to most commercially available antibiotics is occurring rapidly. Consequently, a pressing necessity exists to identify and detect new antimicrobial substances. This study aimed to analyze the antioxidant and antibacterial activity of nanoemulsion clove extract and grape seed oil. This research was conducted in June 2023 using experimental methods at the Research Laboratory of the Universitas Islam Bandung Pharmaceutical Study Program by developing a nanoemulsion preparation containing clove extract (Syzygium aromaticum L.) and grape seed oil (Vitis vinifera L.). Antioxidant activity was tested using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Antibacterial activity was tested using the agar diffusion method by measuring the growth inhibitory diameter of Staphylococcus aureus and Streptococcus mutans bacteria and divided into four groups formulas based on the addition of clove extract with different concentrations in the nanoemulsion base (FA=0.25%, FB=0.5%, FC=0.75%, and FD=1%) to see the best results. The result shows nanoemulsion preparations have antioxidant properties in the DPPH test. The FA formula has the highest IC50, namely 1,117.56 ppm. The antibacterial activity of Staphylococcus aureus and Streptococcus mutans has an inhibition zone, although it is still in the category of inhibiting bacterial growth, but does not kill growth. The nanoemulsion formulation, comprising clove extract and grape seed oil, has exhibited exceptional antioxidant properties and substantial antimicrobial efficacy against prevalent oral bacterial strains.

Abstract

Health reproduction knowledge is a crucial factor in preventing acts of early sexual behavior. Early sexual behavior is reflected in many ways, from attraction to different sexes to building a relationship and making physical contact. Adequate knowledge of sexuality in teenagers especially in health reproduction would prevent teenagers from acting in early sexual behavior. This activity aims to increase knowledge about the health of reproductive organs and the prevention of early sexual intercourse among Madrasah Aliyah students. The method used is education regarding the health of reproductive organs, pre-marital sexual psychology, and social jurisprudence approaches. All material is presented interestingly and interactively. This activity found that 63 percent of the participants had previous knowledge of this topic. More than 50 percent of respondents were students, and students had quite good knowledge about reproductive health. Madrasah Aliyah students already have sufficient knowledge about reproductive health, but it has not yet been seen whether it is enough to prevent students from premature sexual behavior. However, we do not have any data regarding the act of early sexual behavior among respondents or how knowledge in health reproduction would relate to the act of early sexual behavior.
