The Aloe vera plant, also known as the Lidah buaya plant, has antibacterial properties due to its secondary metabolites, which include alkaloids, flavonoids, tannins, and saponins. In this study, endophytic fungi from Lidah Buaya (Aloe vera) were isolated against bacteria that cause gastrointestinal tract infections using TLC-Bioautography and Agar Diffusion. In this study, 7 isolates of endophytic fungi were obtained, one of which was IFLB 1 which had potential as an antibacterial, purification of the endophytic fungi was carried out and then macroscopic examination was carried out on the fungi to see the colonies formed. After that, a screening test was carried out for isolates of endophytic fungi. Then the isolates that gave the best activity were reproduced and continued with the fermentation process for 14 days. The extraction results were then evaporated to obtain a thick extract and a Thin Layer Chromatography (TLC) Identification test was carried out in which the eluent used was chloroform: methanol (5:1). Then continued the TLC-Bioautographic Antibacterial Activity Test on Escherichia coli, Salmonella thypi, Shigella dysentriae and Vibrio cholerae bacteria and obtained 2 active spots with Rf1 = 0.78 and Rf2 = 0.30.

Prevention of the transmission of covid 19 can be done by implementing the health protocol, namely 3M (wearing masks, washing hands and social distance). Based on research, the use of masks can reduce the risk of transmission of COVID-19 by 45 percent as well as hand washing reduces the risk by 35 percent. WHO recommends washing hands with soap/antiseptic for 20-30 seconds and applying the right steps. Another effort is to maintain a distance of at least 1 meter and avoid crowds. To assist the government in preventing the transmission of covid 19, socialization of the 3M activity was carried out at the Darul Istiqamah Maros Islamic Boarding School which is located on the Maros-Makassar Street, Mandai District, Maros Regency. This location was chosen because Maros was the third highest area with the number of people who are positive for the corona virus in South Sulawesi. Islamic boarding school students are a partner group that is expected to apply the 3M health protocol so as to prevent the transmission of covid 19. The activity is carried out by providing counseling about the importance of implementing 3M, how to implement 3M and also by distributing masks, soap and disinfectants needed to implement health protocols. The activity was carried out well and received a good response from the participants with 33 participants from various classes who were students of the Darul Istiqamah Islamic Boarding School Makassar.
