Biodiversity and Potential Use of Macro Algae in Pesisir Barat Lampung

Abstract

Pesisir Barat Regency in Lampung has abundant marine biological wealth that has not been widely known and utilized by the community, one of them is macro algae. The objectives of the research were to identify the types of macro algae and to explains the potential use of macro algae in the Pesisir Barat Lampung Region. The study used cruise method. The findings were identified by experts to validate the results of classification, morphology, and qualitative studies regarding the potential use and benefits of macro algae. From the results of this study, 15 species of macro algae were found on Tanjung Setia Beach included; 3 species of green algae (Chlorophyta) consist of Halimeda opuntia L., Caulerpa racemosa F., Ulva lactuca L .; 7 species of brown algae (Phaeophyta) consist of Padina pavonica L., Padina australis H., Sargassum vulgare C.A., Sargassum polycystum C.A., Turbinaria ornata J.A., Turbinaria ornata J.A., Fucus vesiculosus L.; and 5 species of red algae (Rhodophyta), consist of Corallina officinalis L., Gigartina pistilla S., Gigartina disticha S., Gracilaria verrucosa, H., Rhodymenia pseudopalmat J.V.L.The benefits of this research for society to provide insight into the potential use of macro algae which can be utilized in many fields. For students, provide information on the biodiversity of macro algae in the sea.

Physical and Chemical Characteristics of Green Algae Halimeda opuntia Calcium Powder Extracted Using Hydrochloric Acid

“…Kusumawati et al (2022) and Zainol et al (2019) mentioned that using HCl in calcium extraction will dissolve the calcium and the organic compounds, such as protein. The existing correlation between the extraction method and using HCl to extract will benefit the calcium food enrichment (Asih et al 2019). Rosnah et al (2021) reported that 4% HCl could be used for calcium extraction in chicken egg cells.…”

Characteristics of Powder Agar Extracted from Different Seaweeds Species and Locations

“…Agar, having the ability to form a gel, can be used as an emulsi er, stabilizer, gelling agent, or thickener. This product is usually extracted from seaweed using the hot water extraction method in acidic conditions (Asih et al 2019).…”

The Agar Production, Pigment and Nutrient Content in Gracilaria sp. Grown in Two Habitats with Varying Salinity and Nutrient Levels

“…serves as an excellent source of polysaccharide, i.e. agar also rich in pigmented antioxidants such as chlorophyll and carotenoids (Stengel et al, 2015;Asih et al, 2019). Polysaccharides from seaweed are frequently related to pharmacological activities (Hamed et al, 2015) such as anticoagulant, antioxidant (Yudiati et al, 2018a;2018b), antitumor, and immunomodulatory of shrimp (Litopenaeus vannamei) (Yudiati et al, 2016(Yudiati et al, , 2019 as well as Zebrafish (Yudiati et al, 2020) Common salinity at sea in marine waters is around 35 ppt.…”
