Abstract

This study aims to determine the effectiveness of the brown algae extract Padina australis in inhibiting the growth of Bacillus cereus and Eschericia coli bacteria. Samples were taken from the waters of Osi Island, West Seram, Maluku Province as much as 1 kg, the sample was then dried using the sundrying method. The dried sample was then soaked for 24 hours and extracted. The extract results were then tested for phytochemicals and antibacterial activity tests carried out in the Microbiology Laboratory of Pattimura University, Ambon. The results showed that (1) The brown algae extract Padina australis contains secondary metabolites in the form of flavonoids, terpenoids, steroids, saponins and alkaloids; (2) The combination of these various compounds provides a synergistic effect that can increase the effectiveness of antimicrobials in inhibiting the growth of Bacillus cereus and Escherichia coli bacteria; (3) The minimum inhibitory concentration (MIC) of Padina australis algae extract has different abilities in inhibiting test bacteria. The MIC of Bacillus cereus bacteria at a concentration of 10% has an inhibition zone of 7 mm and the MIC of Escherichia coli bacteria at a concentration of 60% has an inhibition zone of 11 mm.

Abstract

Sorghum is a potential alternative food source due to its high carbohydrate, fiber, and protein content, which surpasses that of rice, as well as its greater adaptability to marginal land and dry weather conditions. However, sorghum productivity is often hindered by suboptimal fertilizer use, necessitating additional solutions like biostimulants. Seaweed-based biostimulants, such as Padina minor, hold promise in enhancing plant growth by stimulating nutrient absorption, improving resistance to abiotic stress, and enriching soil quality. This study aimed to evaluate the effectiveness of P. minor extract in increasing chlorophyll levels in sorghum plants. The experiment was conducted using a Completely Randomized Design (CRD) with varying concentrations of P. minor extract (20%, 30%, and 40%) and application frequencies (1, 2, and 3 times). The research results showed that (1) a concentration of 20% with administration of the extract once gave a significant increase in chlorophyll levels compared to other concentrations and frequencies; (2) administration of biostimulants in low concentrations and with fewer administration frequencies has proven to be more effective; (3) higher concentrations and frequencies of biostimulants can cause toxicity to plants; (4) the use of P. minor extract as a biostimulant can be a sustainable alternative in agricultural practices to improve the quality and productivity of sorghum.
