Abstract

Background: The coastal waters in the intertidal zone of Tulehu Village, Salahutu District,
Ambon Island are a good habitat for the growth of various types of macroalgae which ecologically
have an important role for the sustainability of various types of marine biota, because the growth
of various macroalgae is very fast with various thallus, allowing an ecosystem to form as a place
to live. live various marine biota.
Methods: This research is a descriptive study using sampling techniques for types of Algae by
survey in the intertidal zone of coastal waters in Tulehu Village, Ambon Island, Salahutu District,
Central Maluku Regency. The Algae sampling process was carried out during the tides from
January 6 to January 20 2024. . This research is a descriptive study using sampling techniques
for types of Algae by survey in the intertidal zone of coastal waters in Tulehu Village, Ambon
Island, Salahutu District, Central Maluku Regency.
Results: The findings of marine macroalgae in the Intertidal Zone include Chaetomorpha crassa,
Achanthopora muscoides, Gracilaria arcuate, Valonia fastigiata, Ulva lactuca, Sargassum
crassifolium.
Conclusion: The macroalgae found in the intertidal zone of the coastal waters of Tulehu Village
on Ambon Island are 6 types of macroalgae, Chaetomorpha crassa, Achanthopora muscoides,
Gracilaria arcuate, Valonia fastigiata, Ulva lactuca, Sargassum crassifolium. Ulva lactuca, brown
macroalgae species Achanthopora muscoides, Gracilaria arcuate and red macroalgae species
Sargassum crassifolium, each type of macroalgae has a different substrate according to the
substrate conditions and the presence of different environmental factors.
