“…Both sodium alginate and potassium alginate can be extracted from species of multicellular brown algae, including Sargassum sp., Turbinaria sp., Hormophysa sp., and Padina sp. [15]. The brown macroalgae are characterized architecturally by an alginophyte cell wall structure composed of ß-D-mannuronic acid and α-L-guluronic acid [16].…”

“…Most of the species of brown algae are prevalent in a number of maritime countries, including Indonesia [17]. Unfortunately, even though Indonesia is surrounded by a Sargassum-rich coastline and considered to have the potential to fulfill all the demand for an alginate-based irreversible hydrocolloids impression material, these resources are still under-cultivated [15]. Against this background, in the present study we aimed to investigate the implementation of alginates from brown algae Sargassum polycystum as dental impression material and compare it with commercially available alginate product.…”

This study aimed to investigate the potential use of brown algae Sargassum polycystum as irreversible hydrocolloid (alginate) impression material. Potassium alginate extracted from Sargassum polycystum was prepared in three different compositions (14%, 15%, and 16%) and mixed with other standard components to form an alginate impression material. Prior to that, the purity of potassium alginate was quantified with Fourier Transform Infrared Spectroscopy (FTIR) analysis. As a control material, the alginate impression material from a commercially available product was used. All alginate impression materials were then applied to a die stone model. Dimensional accuracy was measured by calculating the mesiodistal width of incisors in the generated dental cast using a digital caliper 0.01 accuracy (five replications). In addition, to evaluate the dimensional stability, the impression results were poured at four different periods (immediately, 5 min, 10 min, and 15 min). An independent t-test was performed to compare the measurement results with p < 0.05 considered significant. Analytical results confirm that the impression material containing 15% potassium alginate gives the best dimensional accuracy similar to control (p > 0.05). Meanwhile, the optimal dimensional stability was produced in the impression material containing 16% potassium alginate. Our study suggested that brown algae Sargassum polycystum has a promising potential to be used as an alginate impression material in clinical application.

“…One identified type of brown algae was Padina sp. This species is also found in several Indonesian Waters such as in the Makassar Strait (Hamrun et al 2019), Parigi Moutong Coast, Padang (Dharmayanti et al 2019) and Belitung Lengkuas Coast (Jannah et al 2021). According to Aulia et al (2021), Padina sp., is fan-shaped with a diameter of 3-4 cm, yellowish-brown or whitish due to calcification, consisting of flexible rhizoids for attaching themselves to a surface.…”

Pathogenic bacterial contamination was a serious matter due to its capability in reducing food quality and health. This study aimed to select various types of algae in Luk Coast, Sumbawa Regency that have the potential to produce antibacterial compounds for natural food preservatives. Algae on Luk Coast was identified by means of morphological characters, followed by sample preparation and extraction of secondary metabolites (bioactive compounds). Algae extracts were used in antibacterial tests against food spoilage bacteria, such as Escherecia coli, Staphylococcus aureus, Salmonella thypi, Enterobacter cloacae and Pantoea agglomerans. Five types of algae identified were Padina sp., Halimeda opuntia, Sargassum horneri, Sargassum crassifolium and Galaxaura rugose. The five algae have the growth-inhibiting ability toward the tested bacteria. The highest inhibition zone was obtained from the 100% algae extract concentration.

“…29,30 Baik natrium alginat maupun kalium alginat dapat diekstraksi dari spesies alga coklat multisel, termasuk Sargassum sp., Turbinaria sp., Hormophysa sp., dan Padina sp. 31 Sargassum sp sendiri mengandung alginat dalam kadar tinggi yang cukup untuk memproduksi natrium alginat sebagai komponen utama bahan hidrokoloid ireversibel. Alginat yang diekstraksi dapat dihomogenisasi dalam air untuk membentuk larutan alginat, yang dapat bereaksi dengan kalsium sulfat untuk menghasilkan alginat yang tidak mudah larut.…”

ABSTRACT Two-thirds of Indonesia's territory is mostly waters. The United Nations Convention on the Law of the Sea in 1982 stated that the area of Indonesian waters is 5.8 million km2 and there are 27.2% of all flora and fauna species. Algae is one of the most abundant biological resources in Indonesian waters, which is about 8.6%. In Indonesian waters, there are about 28 species of brown algae from six genera including Dyctyota, Padine, Hormophysa, Sargassum, Turbinaria andHydroclathrus. Brown al-gae have a large alginate content in their cell walls, approximately 40% of their dry weight. The alginate contained in brown al-gae canbe used in industrial fields, such as the dental impression material industry. The main active ingredients in the manufac-ture of irreversible hydrocolloid impression materials are sodium alginate, potassium alginate, and triethanolamine alginate. Sodium alginate and potassium alginate can be extracted from brown algae species such as Sargassum sp.
