Abstract

Bread is a food made from flour and yeast. Bread made using conventional yeast only has limited shelf life because it is susceptible to the growth of fungi such as Aspergillus niger and Rhizopus stolonifer. One way to increase the shelf life of bread is to use Lactic Acid Bacteria (LAB) as a starter for making bread. This research aims to determine the ability of LAB yakult and yoghurt as an antifungal and to test the organoleptic and shelf life of sourdough with LAB formulation. The method used in this research is an experimental methode. The parameters observed were the antifungal activity of yakult and yoghurt with LAB formulation, organoleptic test of sourdough with LAB formulation, and shelf life test of sourdough with LAB formulation. The result showed that yoghurt LAB had antifungal activity, while yakult LAB did not have antifungal activity. Based on organoleptic test, sourdough with the additional of LAB yoghurt has better organoleptic test result compared to white bread without the additional of LAB yoghurt, and sourdough with the addition of LAB yoghurt has a longer shelf life compared to white bread without the additional of LAB yoghurt.

Abstract

The peel of the kepok banana (Musa paradisiaca L.) has been found to contain bioactive compounds that have the potential to accelerate wound healing. The objective of this study was to ascertain the efficacy of a cream formulated from kepok banana peel extract in the healing of incision wounds in mice (Mus musculus). The present study employed a completely randomised design (CRD), with 21 mice divided into seven treatment groups: control cream, sulfadiazine, and banana peel extract cream at concentrations of 3%, 6%, 9%, 12%, and 15%. The treatment was administered for a period of seven days, after which the thickness of the epithelial layer and the density of collagen were measured. The data were analysed using a one-way analysis of variance (ANOVA) and Duncan's test. The results demonstrated that the banana peel extract cream had a significant effect on wound healing (p<0.05). The greatest epithelial thickness was observed at a 3% concentration (69.42 ± 4.45 µm), while the highest collagen density was observed at a 15% concentration (44.10 ± 1.80%). The study concluded that banana peel extract cream is effective in accelerating the healing of incision wounds in mice.
