Abstract

KNOWING MACROALGAE Turbinaria AND THEIR USAGES. Turbinaria is a member of brown macroalgae that can be found in almost all Indonesian waters. Turbinaria is often regarded as Sargassum because they have a similar morphology and both belong to the Family Sargassaceae. There are 35 species of Turbinaria in the world and 11 of which can be found in Indonesia. Turbinaria conoides, T. decurrens and T. ornata are the most common ones in Indonesian waters. Turbinaria grows on rocky intertidal coastlines, tidepools and reef flats. The life cycle of Turbinaria occurs through alternations between sexual and asexual. Their biphasic life cycle contains gametophytes and sprorophytes. In their sexual reproduction, sporophytes resulted from the germination of zygotes formed by fusion (fertilization) of male and female gametes. Asexual spores develop from both sporophytes and gametophytes. Turbinaria was commonly used as a source of alginate, fucoidan and other bioactive polysaccharides (antioxidant, anticancer, antibacterial, anticoagulant, antiploriferative and antivirus activities).

Abstract

ECOLOGICAL ROLE OF MACROALGAE FOR MARINE ECOSYSTEM. Macroalgae is an ecologically and economically important component in marine ecosystem. Ecologically, macroalgae has a role as a primary producer, food for other marine biota, provide shelter, nursery ground and carbon sink. Macroalgae contains photosynthetic pigments to be able to provide their own food and produce carbon dioxide for other marine biota (called primary productivity). Macroalgae is a food source, provide shelter and nursery ground for fish, gastropods (mollusks), crustaceans and sea urchins. Macroalgae also has the ability to to reduce the effects of global warming through carbon sink. Absorption of carbon emissions of anthropogenic activity by marine organisms are called as blue carbon. Therefore, macroalgae is ecologically importantfor the balancing of marine ecosystems sustainability.

Abstract

Rocky shore intertidal occurs at the interface of the land and sea, which regularly exposed with tidal waves. In general, rocky shore intertidal is influenced by extreme physical factors, so organisms need to adapt well. Macroalgae on rocky shore intertidal are mostly macroalgae that have epilithic life foam, for example, Sargassum, Turbinaria, Hypnea, Gracilaria, Amphiroa, Chaetomorpha, Ulva, Acanthophora, and Gelidium. The role of macroalgae on rocky shore intertidal are as a primary producer/primary productivity, food for other organisms (fish, mollusc, sea urchin, crab), nursery ground for other organisms (fish, sea urchin, sea cucumber, and crab), and provide shelter for benthic fauna (crabs, sea urchin, molluscs, polychaeta and sea star). The adaptation of macroalgae on rocky shore intertidal was through morphological changes. Gracilaria salicornia on rocky shore intertidal has slimmer thallus than G. salicornia on non-rocky shore intertidal.

Abstract

FUCOXANTHIN: A HIGH VALUE CAROTENOID FROM BROWN MACROALGAE. Fucoxanthin is carotenoid that can be found in marine brown seaweed (macroalgae) and diatoms (microalgae). Fucoxanthin has been isolated from brown macroalgae for its bioactivities study, including: Cystoceira barbata, Sargassum aquifolium, Sargassum filipendula, Sargassum ilicifolium, Sargassum wightii, Alaria crassifolia, Cladosiphon okamuranus, Cystoseira hakodatensis, Eisenia bicyclis, Fucus serratus, Fucus vesiculosus, Hijikia fusiformis, Ishige okamurae, Kjellmaniella crassifolia, Laminaria japonica, Laminaria ochotensis, Myagropsis myagroides, Padina tetrastromatica, Petalonia binghamiae, Sargassum fulvellum, Sargassum heterophyllum, Sargassum horneri, Sargassum siliquastrum, Undaria pinnatifida, Sargassum longifolium, Padina sp, Turbinaria sp, and Undaria pinnatifida. The amount of fucoxanthin depends on the species of algae. Fucoxanthin has been reported to have bioactivities, i.e. antioxidant, antiinflammatory, anticancer, antiobese, antidiabetic, antiangiogenic, and pigmentation inhibitory.

Abstract

CHARACTERISTIC AND IMPACTS OF INTRODUCED MACROALGAE. An introduced macroalgae is species of macroalgae that have been introduced beyond its native range through human activities and has become successfully established in the new locale. Introduced macroalgae have an impact on ecology and evolution, i.e. direct and indirect competitions with native biota (space monopolization and change in community composition), effects on higher trophic levels (herbivores, associated fauna, toxicity), habitat change (changed structure, sediment accumulation), change of ecosystem processes (alteration of trophic structure) and genetic effects. Introduced macroalgae also have an impact on economy and social, i.e. costs of loss of ecosystem functions or values, impacts on environmental amenity, impacts on human health, management costs (government/non-government), costs of research into introduced species, costs for eradication and control measures and costs for education/extension campaigns. Management of impact and research are needed to minimize the impact of introduced macroalgae.
