Abstract

Antibacterial is a compound used to control the growth of harmful bacteria. Mangrove plants are strongly suspected to have bioactive content, the bioactive content contained in mangrove plants is useful in the pharmaceutical field as a medicinal ingredient. Sonneratia alba root contains secondary metabolite compounds Flavanoids, tannins and alkaloids that act as antibacterials. The purpose of this study was to determine the antibacterial activity of S.alba ethanol extract against Staphylococcus aureus bacteria and Escherichia coli bacteria. Extraction method by maceration, long extraction time 3 days. The extract obtained is then evaporated solvent in the rotary evaporator then the extract results are made concentrations of 25?g, 50?g, 100?g, and 150?g. antibacterial testing using the Kirby-Bauer method. The results showed that at concentrations of 25?g, 50?g, 100?g, and 150?g Sonneratia alba mangrove roots had antibacterial activity. But those that have strong antibacterial activity in Escherichia coli bacteria are at a concentration of 50? with while in Staphylococcus aureus bacteria are at a concentration of 150?g with an inhibitory zone of 18.6mm, and in Escherichia coli bacteria with an inhibitory zone of 18,3mm.

Abstract

Sea grapes (Caulerpa racemosa) contain various secondary metabolites with bioactive compounds that function as antibacterial agents. This study aimed to evaluate the antibacterial activity of ethanol extract from sea grapes (Caulerpa racemosa) against Helicobacter pylori. The method used was the agar diffusion technique with paper discs at four different extract concentrations: 500 µg, 600 µg, 700 µg, and 800 µg per disc. Extraction was carried out through maceration using 96% ethanol as the solvent, and antibacterial activity was assessed based on the formation of inhibition zones around the discs. The results showed that all extract concentrations exhibited very strong inhibitory effects on the growth of H. pylori, with inhibition zones of 27.23 mm, 28.51 mm, 29.91 mm, and 31.51 mm, respectively. The higher the extract concentration, the larger the inhibition zone formed. Based on antibacterial activity categorization, Caulerpa racemosa extract demonstrates potential as a strong antibacterial agent against Helicobacter pylori.

Abstract

Mokoditek Village in North Bolaang Mongondow has great agricultural potential, especially in corn and rice production. However, low productivity and limited technology have caused local farmer groups, especially the Singkanaung Farmers Group, to be unable to optimize their agricultural output. This research aims to increase the production capacity and management of farmer groups through the application of appropriate technology and intensive training. The results of the program showed an increase in corn productivity from 3 tons/ha to 4 tons/ha. In addition, financial management training has strengthened the capacity of farmer group members to manage agricultural businesses more efficiently and sustainably.
