Abstract

Padina australis is a brown algae that has secondary metabolites such as phenols, tannins, flavonoids, saponins, and alkaloids that have antibacterial potential. This study aims to determine the antibacterial activity of Padina australis extract against spoilage bacteria of tuna (Euthynnus affinis) from genus Staphylococcus sp. and Bacillus sp. through disc diffusion method. Data on the diameter of the inhibition zone were analyzed statistically. The results showed that Padina australis extract was able to produce an inhibition zone in both isolates, but the antibacterial activity was relatively weak (≤ 5mm). The 60% extract concentration produced the highest inhibition zone of 2.07 mm in Staphylococcus sp. and 2.23 mm Bacillus sp. isolates, while the positive control produced strong to very strong antibacterial activity, with diameters of 19.28 mm and 33.76 mm. The results of statistical analysis showed that variations in extract concentration did not significantly affect the inhibition zone in both isolates (p = 0.119 and p = 0.160). The low antibacterial activity is likely due to limited content of bioactive compounds, the extraction method, and suboptimal diffusion of the extract on the agar medium. Padina australis extract has the potential as a natural antibacterial, but its effectiveness still needs to be improved with further optimization.

Abstract

Based on data from the non-communicable disease programmer at the Wajo Health Center in Baubau City, the risk of diabetes mellitus occurs from the age of 15 years and above, in 2020 the number of sufferers was 296 cases and in 2024 it increased with the number of sufferers being 301 cases. In this case the number of cases of diabetes mellitus increased from 2020 to 2024. The aim of the study was to determine the related factors such as knowledge, obesity, physical activity and diet with type 2 diabetes mellitus in productive age (15-64 years) in the Wajo Community Health Center Working Area, Baubau City in 2025. This study employed a quantitative cross-sectional study design. The population comprised 301 productive-age individuals (15-64 years) in Lamangga, Tanganapada, and Wajo sub-districts, with a sample size of 72. The sampling technique used was random sampling with univariate and bivariate analysis. The chi-square test was used. The results showed a relationship between knowledge (p-value = 0.029 < 0.05), obesity (p-value = 0.012 < 0.05), physical activity (p-value = 0.002 < 0.05), and dietary patterns (p-value = 0.000 < 0.05) and the incidence of type 2 diabetes mellitus in the Wajo Community Health Center, Baubau City.
