Abstract: Infection usually caused by microorganism such as bacterial. One example of infection is abscess which caused by Staphylococcus aureus. Staphylococcus aureus is a pathogenic bacterial in mouth. Seaweed is a part of sea plants. Nowadays, seaweed has been used as material of agar-agar, alginate, and even medicine. Indonesia has good potential to develop and use its richness at the sea. One of species that has been cultivated is Gracilaria verrucosa or known with local name “bulung rambu” (Bali) or “sango-sango” (Sulawesi). The characteristics of Gracilaria verrucosa is thallus silindris, slick, and has yellowish-brown or yellowish-green. Green, red, or brown seaweed is a potential source of bioactive compound that useful for pharmacy industry improvement like antibacterial, antivirus, antifungal, and cytostatic. This study purpose was to find out if seaweed extract (Gracilaria sp.) can inhibit growth of Staphylococcus aureus. This study was an experimental laboratory with true experimental design and posttest only control design. study subject are seaweed extract Gracilaria sp. that dissolved with 95% ethanol which evaporated in oven. Inhibition zone of Gracilaria sp. extract evaporated in the oven at each repeated were 2.5mm, 3.5mm, 3mm. Inhibition zone created from Gracilaria sp. extract that evaporated with vacuum rotary evaporator in each repeated were 2mm, 2mm, and 2.5mm. Study results showed that seaweed extract (Gracilaria sp.) didn’t have exhibition zone against Staphylococcus aureus.Keywords: inhibition test, seaweed (gracilaria sp), staphylococcus aureus.Abstrak: Penyakit infeksi yang biasanya disebabkan oleh mikroorganisme yaitu bakteri. Salah satu contoh penyakit infeksi tersebut yaitu abses yang disebabkan oleh bakteri Staphylococcus aureus. Staphylococcus aureus adalah patogen utama dalam rongga mulut. Rumput laut merupakan bagian dari tumbuhan laut perairan. Saat ini rumput laut telah dimanfaatkan sebagai bahan baku industri agar-agar, dan alginat bahkan obat-obatan. Indonesia mempunyai potensi yang baik untuk mengembangkan dan memanfaatkan kekayaan lautnya. Salah satu jenis yang sudah banyak dibudidayakan adalah Gracilaria verrucosa atau dikenal dengan nama daerah bulung rambu (bali) atau sango-sango (sulawesi). Ciri-ciri dari Gracilaria verrucosa, yaitu thallus silindris, licin, dan berwarna kuning-coklat atau kuning-hijau.Rumput laut hijau, merah ataupun coklat merupakan sumber potensial senyawa bioaktif yang sangat bermanfaat bagi pengembangan industri farmasi seperti sebagai antibakteri, antivirus, antijamur dan sitotastik. Penelitian ini bertujuan untuk mengetahui apakah ekstrak rumput laut (Gracilaria sp.) dapat menghambat pertumbuhan bakteri Staphylococcus aureus. Penelitian ini merupakan penelitian eksperimental laboratorium, menggunakan rancangan eksperimental murni (true experimental design) dengan rancangan penelitian posttest only control design. Subjek dari penelitian ini ialah ekstrak rumput laut Gracilaria sp. yang dilarutkan dengan etanol 95% yang dievaporasi menggunakan rotary vacuum evaporator dan dipanaskan dalam oven. zona hambat dari ekstrak Gracilaria sp. yang dievaporasi dengan oven pada masing-masing pengulangan ialah 2,5 mm, 3,5 mm, 3 mm. Demikian juga zona hambat yang terbentuk dari ekstrak Gracilaria sp. yang dievaporasi dengan vacuum rotary evaporator pada masing-masing pengulangan ialah 2 mm, 2 mm, dan 2,5 mm. Hasil penelitian menunjukkan bahwa ekstrak rumput laut (Gracilaria sp.) tidak memiliki daya hambat terhadap bakteri Staphylococcus aureus.Kata kunci: uji daya hambat, rumput laut (gracilaria sp.), staphylococcus aureus.

AbstractSeveral seaweed extracts have been reported to have potential antimethanogenic effects in ruminants. In this study, the effect of three brown seaweed species (Undaria pinnatifida, UPIN; Sargassum fusiforme, SFUS; and Sargassum fulvellum, SFUL) on rumen fermentation characteristics, total gas, methane (CH4), carbon dioxide (CO2) production, and microbial populations were investigated using an in vitro batch culture system. Seaweed extract and its metabolites, total flavonoid and polyphenol contents were identified and compared. For the in vitro batch, 0.25 mg∙mL−1 of each seaweed extract were used in 6, 12, 24, 36 and 48 h of incubation. Seaweed extract supplementation decreased CH4 yield and its proportion to total gas production after 12, 24, and 48 h of incubation, while total gas production were not significantly different. Total volatile fatty acid and molar proportion of propionate increased with SFUS and SFUL supplementation after 24 h of incubation, whereas UPIN was not affected. Additionally, SFUS increased the absolute abundance of total bacteria, ciliate protozoa, fungi, methanogenic archaea, and Fibrobacter succinogenes. The relative proportions of Butyrivibrio fibrisolvens, Butyrivibrio proteoclasticus, and Prevotella ruminicola were lower with seaweed extract supplementation, whereas Anaerovibrio lipolytica increased. Thus, seaweed extracts can decrease CH4 production, and alter the abundance of rumen microbial populations.

‘Hamlin’ sweet orange trees on ‘Carrizo’ citrange and ‘Swingle’ citrumelo rootstocks were treated weekly with a commercial extract of the brown seaweed Ascophyllum nodosum at 5 and 10 mL·L−1 as either a soil drench or foliar spray. Half of the trees in each treatment were subjected to drought stress [irrigated at 50% of evapotranspiration (ET)], whereas the other half remained fully irrigated (100% ET). Drought stress reduced shoot growth and leaf photosynthesis but increased root and total plant growth relative to the amount of water applied, thus increasing whole plant water use efficiency. Trees treated with seaweed extract and drought-stressed had significantly more total growth than untreated drought-stressed trees for both rootstocks. The maintenance of growth by the seaweed extract under drought stress conditions was unrelated to photosynthesis. However, the seaweed extract treatment did have a significant effect on plant water relations. Soil drench-treated trees had more growth and higher stem water potential than foliar-treated or control trees after 8 weeks of drought stress. These results indicate that seaweed extract may be a useful tool for improving drought stress tolerance of container-grown citrus trees.
