Sargassum sp. is a known genus of brown seaweed whose dominant component is alginic acid or alginate. Various studies found that alginate having proinflammatory activity, so it may have potential to improve the wound healing process. This study aimed to obtain sodium alginate extract and to know the potency of the sodium alginate extract in incision wound treatment in mice abdomen. Lotion application was performed once a day in a span of five consecutive days. Observation on the wound was carried out to obtain data on blood coagulation, tissue reparation, and fibroblast development rate on the wound using histology. The results showed that the average yield from the Sargassum sp. extraction process was 31.3%. Quality control of the prepared lotion included organoleptic test; light brown coloration, lotion specific odor, semi- solid texture. The acidity of the lotion was measured as 6.61 with 6.731 cp of viscosity. The lotion adhesiveness test showed 0.21 seconds and the lotion was shown to be oil-in-water. Application of the lotion on incision wounds made in the abdomen of rats showed blood coagulation on the first day and onset of wound reparation process on the second day. Wound observation by the third day showed that the inflicted area had undergone a near-complete reparation. The study also showed that on the fifth day of reparation Sargassum sp. extract lotion treatment group showed fibroblast formation, as opposed to the non-extract lotion treatment group. Previous study use alginates as wound dressing material, but in this study alginate used as active ingredient in wound healing treatment. Therefore, this study concludes that sodium alginate in Sargassum sp. seaweed has a potential application in the field of medicine.

The water quality found on the surface is usually better than that accumulated at the seabed and more bottomless sea. When recycled, water usually brings many materials along the path, all the way to reaching its end. Water quality varies from place to place, season, and different types of rock and soil it passes through also influences the possessed quality. By employing Penaeus merguiensis larvae produced by the Marine Research Center Hatchery owned by Jepara's government, this study analyzes varying effects in three nominal salinities (28, 32, and 36 ppt) and types of diets (Diet A: 100% live feed; Diet B: 100% FRIPPAK; Diet C: a combination of Diet A and Diet C, 50 % each) and finds the optimum water quality parameters such as dissolved oxygen, pH, and temperature on the growth of the newly introduced Penaeus merguiensis larvae. The results show that two nominals of water salinities (28 and 32 ppt) with Diet A works well, supporting the growth from most Zoea to Postlarvae-1: Zoea-1 at 28 ppt with Diet A; Zoea-2 at 32 ppt with Diet A; Zoea-3 at 32 ppt with Diet A; Mysis-1 at 28 ppt with Diet A; Mysis-2 at 28 ppt with Diet C; Mysis-3 at 28 ppt with Diet A; Postlarva-1 at 28 ppt with Diet A. All shrimp prefers temperature ranging from 31-32.4 °C with dissolved oxygen of 4.9-5.74 ppm and pH 7.0-8.1.

Vibrio vulnificus, Vibrio parahaemolyticus and Vibrio harveyi have been found in aquatic environments and suspected as the primary trigger of WFD (White Feces Disease) outbreaks in aquaculture. This Vibrio spp. has an antibiotic resistance to Ampicillin, Co-Amoxiclav, Amoxicillin, Azithromycin, Actinobacteria and Ciprofloxacin HCL. Actinobacteria and alginate have been reported to increase the marine biota resistance against diseases through prebiotic and probiotic mechanisms. This study aims to discover and increase the secondary metabolite production of Actinobacteria-Alginate and its ability as anti-vibrio. Alginate extraction in the samples dated September 2020 originally from Teluk Awur Bays, Jepara, Central Java, Indonesia (33.73±1.84%) was considerably higher than in May 2021 (22.67±0.3%). Samples were taken from sediment and mangrove root. Actinobacteria strains are macroscopically and microscopically similar to the genus Streptomyces. The most well-known antibiotics were produced by Streptomyces spp. The anti-vibrio test was carried out by Kirby-Bauer disc diffusion. The results were observed by measuring the inhibition zone surrounding the paper disc using a digital calliper. Co-culture strain 90 together with alginate have an approved antibacterial activity against all Vibrio spp. in the concentration of 10.disc-1 mg and 5 mg.disc-1. Co-culture Actinobacteria with alginate has remarkably changed the green-yellow color to olive green/dark red-orange (strains 3, 62, 63, 72, and 90), indicating the transformation of the formation alginate with pigments into other compounds through the biosynthetic pathway. Therefore, alginate enables to support of Actinobacteria by induction the active secondary metabolite as an anti-vibrio to counteract the bacterial pathogen diseases.
