Abstract

Sawo (Manilkara zapota) is a fruit plant that belongs to the Sapotaceae family. Sapodilla plants are tropical plants that are easily adaptable to various temperatures, rainfall, soil, and soil salinity. This plant has been widely cultivated and used traditionally as medicine. Sapodilla plants are widely cultivated in yards, gardens and are very easy to find in the market. Staphylococcus aureus bacteria are gram positive bacteria, immobile, not spore-forming and capable of forming capsules, cocci-shaped and arranged like grapes, one of the causes of diarrhea is Staphylococcus aureus bacteria. To overcome this disease by providing antimicrobial agents of natural origin that can inhibit the growth of these bacteria. This study was conducted with the aim of knowing the antibacterial activity of the ethanol extract of rambutan seeds with concentrations of 45%, 50%, 55% and 60% against the growth of Staphylococcus aureus bacteria. This research method uses an experimental method, namely to determine the antibacterial activity of ethanol extract from sapodilla leaves against the growth of Staphylococcus aureus bacteria. This research used 96% ethanol as solvent. The test was carried out through several stages including material collection, preparation of simplicia, manufacture of ethanol extract from sapodilla leaf simplicia by maceration and testing of antibacterial activity against Staphylococcus aureus bacteria. Based on the identification of sapodilla leaf simplicia powder, there are trichomes or hair coverings, stomata and calcium oxalate crystals. Phytochemical screening test of the thick extract of sapodilla leaves contains a group of alkaloid compounds, flavonoids, saponins, steroids/triterpenoids and tannins. The results of the antibacterial activity test of sapodilla leaf extract against Staphylococus aureus bacteria had an average inhibitory activity at concentrations of 45% (9.4 mm), 50% (12.2 mm), 55% (14.8 mm) and 60% (16.3mm). As a comparison, Cloramfenocol 30 g was used to produce an inhibitory power of 20,18 mm and the best results obtained were at a concentration of 60% which had an inhibitory power of 16.3 mm

Abstract

Porang tuber (Amorphophallus oncophyllus Prain) contains carbohydrates, fats, proteins, minerals, vitamins, and dietary fiber which are thought to be alternative growth media. This study aims to determine the growth of alternative media for microorganisms with Porang tubers. This research was conducted in the Pharmaceutical Chemistry laboratory, at Sari Mutiara University, Indonesia. Samples of Porang tubers were obtained from Porang plantations in the Amplas area, North Sumatra. This study uses an experimental method. Characterization of Porang tuber powder was found 9.54% water content, 9.09% water soluble extract content, and 1.43 total ash content.to contain%Secondary metabolites contained in Porang tuber starch were alkaloids and carbohydrates. The process of making starch begins with soaking with NaCl to remove the sap on the Porang tubers. Furthermore, the grating process is carried out until a precipitate of Porang tuber starch is found which will then be dried into Porang tuber starch. The manufacture of starch media respectively used a concentration of 5% (F1); 7.5% (F2) and 10% (F3). Then added agar, NaCl, and milk. Furthermore, microbiological tests were carried out using Staphylococcus aureus, Escherichia coli, and Candida albicans with the pour method. The comparison used is Nutrient agar and Potato dextrose agar. Furthermore, observations of the growth of these microorganisms were carried out. The results of the test Porang tuber starch showed yeast and bacteria growth media. The result of colony growth was found that the most colonies were found in formula 3 with Candida albicans as many as 297 colonies. The number of Staphylococcus aureus was found to be in formula 2 with 251 colonies, and for Escherichia coli, the most colonies were found in formula 3 with 143 colonies. Conclusion From the results of the study, it was found that Porang tubers can be used as growth media, Staphylococcus aureus, Escherichia coli, and Candida albicans.

Abstract

HIV/AIDS is a disease that continues to grow and becomes a global health problem in both developed and developing countries. The number of cases of HIV/AIDS in adolescents has increased, where adolescents are a group at risk for HIV/AIDS transmission. High social mobility of adolescents causes social, cultural, cultural, and physical and psychological changes. As a result, adolescents have a high vulnerability to transmission of various types of diseases, especially HIV/AIDS. Good knowledge about the disease will help adolescents to make efforts to prevent HIV/AIDS. The purpose of this study was to describe the knowledge of adolescents about HIV/AIDS in SMP Madya Utama Medan. This research method is a research with quantitative approach with descriptive type and cross sectional design. The sampling technique used was purposive sampling. The sample in this study were students of class VIII and IX SMP Madya Utama Medan, as many as 45 respondents. The statistical test used is a univariate test which produces a variable frequency distribution. Data collection by using a knowledge questionnaire. The results showed that from 45 respondents, 34 respondents (53.33%) had less knowledge about HIV/AIDS, 12 respondents (26,67%) had good knowledge and 9 respondents (20,0 %) had sufficient knowledge. Most teenagers have less knowledge about HIV/AIDS, so it is necessary to increase knowledge through the provision of health education related to HIV/AIDS and its prevention.

Abstract

Knowledge about HIV/AIDS is considered important in the formation of stigma because it plays a role in correcting the wrong perceptions circulating in society including information about people who are at high risk of contracting HIV/AIDS, prevention of HIV/AIDS transmission, transmission mechanisms and what intermediaries can transmit HIV/AIDS. Knowledge about HIV/AIDS can be increased through information sources such as the role of health workers, the role of school education and the role of information media. HIV/AIDS (Human Immunodeficiency Virus/Acquired Immuno Deficiency Syndrome) stigma is part of the cognitive component of a person or community group that judges PLWHA (People with HIV/AIDS) negatively so that society takes a stance of rejection or discrimination against PLWHA. The stigma of PLWHA can be seen from the poor mindset of society that avoids sufferers due to excessive fear and unfair treatment of PLWHA. Lack of understanding of HIV/AIDS knowledge is the main cause of the formation of this stigma in society. Knowledge about HIV/AIDS (Human Immunodeficiency Virus/Acquired Immuno Deficiency Syndrome) is one of the factors that play a role in the formation of stigma towards HIV/AIDS. This study aims to determine the relationship between the level of knowledge about HIV/AIDS and the stigma of HIV/AIDS in high school students. This study is a descriptive study. The measuring instrument used was a closed questionnaire to obtain data in the form of knowledge and stigma values ​​that have been categorized in 60 grade XI students of SMA Negeri 17 Medan. The results of the study found that the level of knowledge in the low category was owned by 10 students (16.7%), sufficient 9 students (15%), good 41 students (68.3%) and high stigma category was owned by 4 students (6.7%), moderate 32 students (53.3%), low 24 students (40%).
