The Distribution, Habitat Characteristics, and Bioenergy Potential of Sargassum sp. in Indonesia
Summary
Researchers mapped the distribution of Sargassum, a brown seaweed, across Indonesia's coastal waters, identifying dozens of key growth sites from Sumatra to Papua. This algae holds potential as a bioenergy source and its mapping is also relevant to understanding how floating marine organisms interact with microplastic debris in tropical ocean environments.
Sargassum sp. is a brown macroalgae that has a habitat in tropical marine environments, including Indonesia.Sargassum sp.contains carbohydrate, alginate and bioactive compounds that have the potential to be used for bioenergy.The purpose of this study is to analyze water data to identify conditions suitable for the growth of Sargassum sp. and to pinpoint existing growth locations.The method of this activity is a descriptive method by reviewing articles and references related to the potential of Sargassum sp. and the location of growth points.The result of the study is the potential of Sargassum sp.found in Sumatera, in Lhok Bubon, Simeulue, and Tarahan.In Java, the habitat points of Sargassum sp. are in Karimunjawa, Rembang and Probolinggo.Madura has potential in Saronggi, Talango, Ponjuk, and Gili Genting.Kalimantan can also be found in Singkawang, Lemukutan and Bontang.Sulawesi has potential for Sargassum sp. in Bonerita, Takalar and Barrang Lompo.East Nusa Tenggara has potential in Katundu, Hansisi, Alor, and Netbaun.West Nusa Tenggara is located in Ekas, Gerupuk, Labuan Ijuk, Wane and Cempi.Bali has potential in Sanur, Sawangan, and Serangan.Maluku has potential in Weda, Hatumuri, and Tapi.Papua has potential in Raja Ampat and Manokwari.Environmental parameters that support the growth of Sargassum sp.include a bottom substrate of coral, temperatures ranging from 29.5 -32.7, a salinity of 29-30 ppt, a pH 7.9-8.15,dissolved oxygen levels from 6.7 ppm -8.5 ppm, and light intensity obtained ranged from 590100 Lux to 772100 Lux.

Microplastics Content of Seaweeds in the Mariculture Potential Zone at The Southwest of Coastal Bawean Island
Researchers investigated microplastic contamination in seaweeds from Bawean Island, Indonesia, finding that even sheltered coastal waters contained microplastics in red, green, and brown seaweed species collected from mariculture potential zones.
Pelagic Sargassum as a Potential Vector for Microplastics into Coastal Ecosystems
This research assessed microplastics entrapped within pelagic Sargassum seaweed collected from the Mexican Caribbean coast. The study suggests that Sargassum mats act as vectors transporting microplastics from the open ocean to coastal ecosystems, amplifying plastic pollution in affected shoreline environments across more than 30 nations.
The environmental impact and economic feasibility assessment of composite calcium alginate bioplastics derived from Sargassum
Researchers assessed the environmental impact and economic feasibility of producing calcium alginate bioplastics from Sargassum seaweed, presenting a novel approach that could address both plastic pollution and invasive seaweed problems in the Caribbean.
A new look at the potential role of marine plastic debris as a global vector of toxic benthic algae
Researchers examined marine plastic debris as a global vector for toxic benthic algae, finding that floating plastics provide colonization surfaces that may expand harmful algal distribution and intensify toxic blooms across ocean regions.
Effects of microplastics on typical macrobenthos in sargassum ecosystems
Researchers studied the distribution and toxic effects of microplastics on macrobenthos organisms living in Sargassum seaweed ecosystems. They found that microplastic accumulation in these organisms increased in a concentration-dependent manner, though no significant bioaccumulation was observed up the food chain. The study revealed that microplastics induced oxidative stress and altered intestinal microflora composition in the exposed organisms.
