Abstract

Cempedak is a tropical native fruit from Indonesia and can be consumed by fermenting the skin fruit using a salt solution. The results of the fermentation called Mandai. Fermentation will be successful if there is a role of Lactic Acid Bacteria (LAB). Therefore, this study was conducted to determine the content of LAB in Mandai and isolates when fermented at different times. This study was carried out by dilution and the Pour Plate method, identifications such as morphological identification by gram staining and biochemical test by catalase t and TSIA test. Identification of this study was the observation of clear zone around the bacteria grown on MRSA media as a selective medium for LAB plus CaCO3. In this study, 5 samples of Mandai were used with different fermentation times. The results of the LAB isolation study in Mandai showed that the longer the Mandai fermentation was carried out, the more colonies there would be. While the LAB type was only found in sample 5 which was fermented within 20 weeks. The results obtained were following the characteristics of LAB, including gram-positive bacteria in the form of bacilli or cocci, not having catalase enzyme, and being able to ferment carbohydrates.

Abstract

Bangkal (Nauclea subdita) is a typical plant in the southern part of the island of Borneo. In everyday life, bangkal leaves are used to treat wounds, ulcers, toothache, fever and diarrhea. The purpose of this study was to measure and determine the antibacterial activity of the ethanol extract of bangkal leaves against Staphylococcus aureus using the Ultrasonic Assisted Extraction (UAE) method. Bangkal leaves were extracted by UAE using 96% ethanol. The antibacterial inhibition test was carried out using the Kirby-Bauer disc diffusion method. Testing of antibacterial inhibition zones of Bangkal leaf extract against Staphylococcus aureus bacteria had an effect or significantly different with concentrations of 40%, 60%, 80%, 100% respectively and produced antibacterial activity with inhibition zones of 12.7±0.06 respectively. mm, 13.9±0.00 mm, 15±0.00 mm, 16±0.00mm. The results of the antibacterial activity examination showed that the ethanolic extract of bangkal leaves could inhibit the growth of Staphylococcus aureus at a concentration of 40% with an inhibition zone diameter of 12.7 mm and the highest concentration at 100% with an inhibition zone diameter of 16.00 mm. This indicates that the extract of bangkal leaves has antibacterial activity against Staphylococcus aureus which has an inhibition zone with a moderate to strong category.
