Abstract

Sebatik Island is well-known for its production of According to the Ministry of Maritime Affairs and Fisheries (KKP), seaweed commodities have a significant economic value, as evidenced by the volume of seaweed in the 2021 export market increasing to 225,612 tons with a value of USD 345.11 million. Seaweed productivity is increasing year after year, particularly in terms of seaweed export volume. Carrageenan is a type of galactan polymer discovered as an intercellular matrix material in red seaweed and marine algae of the Rhodophyta class. The purpose of this study is to determine the procedure of extracting carrageenan from Kappaphycus alvarezzi Seaweed, the water content and pH of the extracted carrageenan from seaweed (Kappaphycus alvarezzi), to determine the water content, and the pH value of the carrageenan. The experiment was carried out with NaOH concentrations of 1%, 5%, and 10% added to the treatment. The phases of the seaweed carrageenan (Kappaphycus alvarezii) extraction process include raw material preparation, soaking with NaOH, drying, and storage of seaweed carrageenan (Kappaphycus alvarezii). The water content obtained from the three treatments with 1%, 5%, and 10% NaOH solution addition was 1.35%, 21%, and 18.75%, respectively. The maximum water content was found in 5% NaoH solution, which was 21%, and the highest water content was found in the addition of 10% NaOH solution, which was 18.75%. The pH levels in the three treatments were 8, 7, and 7, respectively.
