Abstract

Liquid soap is a liquid skin cleansing preparation made from soap base with the addition of other permitted ingredients and is used to cleanse the skin without causing irritation to the skin which can be caused by bacteria. This study aims to determine the effect of the addition of ethanol extract of kersen leaves in liquid soap preparations against Staphylococcus aureus bacteria. Liquid soap formulation of ethanol extract of kersen leaves (Muntingia calabura) was formulated in 3 (three) formulations, namely F1 soap preparation with 25% extract concentration, F2 with 30% kersen leaf ethanol extract concentration, and F3 with 35% kersen leaf ethanol extract concentration. Antibacterial testing was carried out using the disc diffusion method. The results of the antibacterial activity test of antiseptic liquid soap preparations F1 soap preparation has an inhibition of 16.82 mm, formulation 2 30% extract concentration has an inhibition of 19.52 mm, F3 extract concentration has an inhibition of 21.90 mm and positive control Dettol soap has an inhibition of 22.22 mm against Staphylococcus aureus bacteria. The conclusion of this study is that ethanol extract of kersen leaves has antibacterial activity against Staphylococcus aureus bacteria and the most optimal inhibitory concentration is kersen leaf extract soap preparation with a concentration of 35% with a very strong inhibition zone category.

Abstract

Wild edible mushrooms are important components of terrestrial ecosystems, particularly in decomposition processes and nutrient cycling. This study aimed to analyze species diversity, distribution, and community structure of wild edible mushrooms in Aceh Selatan, Aceh Tengah, and Aceh Tamiang districts, Aceh Province. Mushroom inventories were conducted using a field walk survey with transect routes as sampling units in potential mushroom habitats. Species diversity was analyzed based on occurrence frequency using the Shannon–Wiener (H’), Margalef (DMg), and Pielou (J’) indices, while beta diversity was assessed using the Jaccard similarity index based on presence–absence data. A total of 10 wild edible mushroom species belonging to 9 families were recorded, exhibiting cosmopolitan, restricted, and unique distribution patterns. The highest species diversity was observed in Aceh Tengah (H’ = 1.963). Beta diversity analysis showed moderate to relatively high similarity among districts (J = 0.50–0.63), with the highest similarity between Aceh Tengah and Aceh Tamiang. Differences in community composition were associated with habitat characteristics, organic substrate availability, and microclimatic conditions.
