Abstract

Seaweed is a macroalgae that has the potential to be developed in coastal areas. K. alvarezii and E.spinosum are international producers of keraginineextract. The limiting factors that affect the growth and quality of seaweed are season and location. The purpose of this study was to analyze the growth and quality of two species of seaweed at different locations and seasons. This research was conducted from January to December 2022. The weight of the seeds seaweed used is 50 grams, which is planted at a distance of 100 meters to 1 km and more than 1 km from the coast in different seasons. This research was conducted in Pallete Waters. The results of water quality studies such as temperature, pH, salinity did not differ by location or season, while current velocity, CO2 and NO3 were very different from planting locations and seasons. Distances of more than 1 km from the coast have lower absolute growth than distances of less than 1 km. During the rainy season the growth is best for both types of seaweed. Viscosity content planted at a location distance of more than 1 km is higher than 100 to 1 km from the coast. Carotenoids have higher levels at a distance of 100 m to 1 km compared to a distance of 1 km from the coast.
