Abstract

A variety of plants are found in the Medan State University (Unimed) campus area which is in the border area of Medan city, precisely in Deli Serdang Regency with an area of ± 495,000 m2. Flowering plants (Angiosperms) are one of the groups of plants that make up the vegetation on the Unimed campus with various types, characteristics (habitus) and various benefits. These flowering plants not only have aesthetic and ecological value but can also be a learning resources. However, there is no data yet on what types of flowering plants (Angiosperms) are found in the campus area. An inventory carried out in the Unimed campus area obtained 80 species of flowering plants belonging to 71 genera and 33 families. The diversity of flowering plants is dominated by the Arecaceae family with 7 species from the monocot group and 13 species from the Fabaceae family which are included in the Dicot group. The various forms of appearance (habitus) of these flowering plants are herbs, bushes, shrubs and trees and their various uses include ornamental plants, shade plants, fruit-bearing plants and medicinal plants.

Abstract

Antibiotic resistance has the greatest impact on human health, at least 2 million people are infected by antibiotic-resistant bacteria. The use of natural medicines is increasingly in demand by the public, one of which is often used to treat diseases is trigona honey. This study aims to determine the antibacterial activity of Trigona honey against Escherichia coli and Klebsiella pneumoniae bacteria. The test bacteria used were Multidrug Resistant Escherichia coli and Klebsiella pneumoniae bacteria obtained from the collection of the Microbiology Laboratory of the University of North Sumatera Hospital. Antimicrobial activity testing was carried out using the hole / well diffusion method on Mueller Hinton Agar (MHA) media with chloramphenicol as a positive control, acetone as a negative control and trigona honey with a concentration of 500 ppm. Antibacterial activity was seen by measuring the inhibition zone formed. The results showed that Trigona honey was able to inhibit the growth of Escherichia coli and Klebsiella pneumoniae bacteria with inhibition zone activity included in the weak category, while the positive control showed antibacterial activity in the strong category.
