Abstract

This research was conducted to assess the antimicrobial activity of Dettol, Betadine, and Harpic against the bacterial growth of Staphylococcus aureus using the disk diffusion technique. The method involved placing sterile paper disks soaked with each test agent onto agar media previously inoculated with S. aureus. Observations revealed that Harpic formed the widest inhibition zone, measuring 15 mm, followed by Dettol with a 12 mm zone, and Betadine with the smallest at 8 mm. Meanwhile, the control disk exhibited no inhibitory effect (0 mm). These results suggest that Harpic has the highest antimicrobial potential among the three products tested in suppressing Staphylococcus aureus growth.

Abstract

This study aims to design and evaluate lipstick preparations by utilizing solid paraffin as the base ingredient and lanolin as an emollient and stabilizer. Solid paraffin was chosen because of its dense properties at room temperature and having the ability to form a stable lipstick structure. In addition, paraffin can provide a smooth, durable surface, and provide good smearing power. On the other hand, lanolin is known as a natural emollient ingredient that functions to moisturize and protect the lips from dryness. Lanolin also has water-retaining properties (occlusive) so that lip moisture is maintained even if the lipstick is used for a long time. The process of making lipstick is carried out by the melting method using indirect heating to maintain the stability of the material and prevent color and aroma degradation. All materials are accurately weighed, then put into beaker glass and heated over three legs using a Bunsen lamp. During heating, the ingredients are gently stirred so that all the components, including solid paraffin and lanolin, melt and mix homogeneously. Once the mixture reaches the desired consistency, the formula is poured into the lipstick mold and allowed to set at room temperature until ready for use. The results of the evaluation test showed that the combination of solid paraffin and lanolin was able to create lipstick with an optimal solid texture, even color, not easy to crack, and had a smooth application power on the surface of the lips. Lanolin plays a big role in providing a soft, moisturizing effect and adding a natural shine to the lips. Meanwhile, solid paraffin helps maintain the shape of the lipstick so that it doesn't break easily when applied. This study also highlights the importance of comparing the composition of ingredients to produce lipsticks that have a stable melting point, good application power, and appropriate adhesion.

Abstract

Understanding the evolution of cells is very important, which means studying the development of living things. The smallest structural elements of living things are cells. These cells gradually change both their structure and function. It can be said that almost all biologists can accept the theory of biological evolution or the theory of evolution that continues to develop , even though the theory is based on circumstantial evidence . The principle of this evolutionary theory is that humans, animals, and plants all evolve continuously. This journal is based on the narrative review method and displays a narrative review design from research journals related to the theory of prokaryotic, eukaryotic, and cell membrane-related evolution. The importance of cells continues to develop along with advances in technology and the discovery of sophisticated tools. Until now it is known that the structure and activities of cells are not as simple as previously thought. Cells that exist today are the result of evolution towards more refined cells. and There are many details in cell evolution that cannot yet be explained.
