Analysis of carrageenan quality of Eucheuma cottonii and Eucheuma spinosum seaweed from Bantaeng Regency and its export permit regulations in Indonesia

Abstract

One of the valuable compounds contained in seaweed is carrageenan, which is found in Eucheuma cottonii and Eucheuma spinosum, the most common species found in Bantaeng Regency, Indonesia. This study aims to measure the quality of carrageenan in those Eucheuma and elaborate on seaweed export regulations in Indonesia. The method used is KCl precipitation, where analysis is carried out on the yield value, moisture and ash content, and pH of carrageenan with reference to the Food and Agriculture Organization (FAO) standards. While the rules for export permits will be explained qualitatively using a statutory approach. The findings showed that the amount of moisture and ash content that met FAO standards was found in Eucheuma cottonii, and it also had the highest yield value. Furthermore, in terms of export permits, exporters need a certificate of origin for seaweed, which is regulated in the Regulation of the Minister of Maritime Affairs and Fisheries No. 7/PERMEN-KP/2013, which aims to provide legal certainty regarding product quality for both exporters and importers. This study recommends that it is required to vary the concentration of the KOH solution used to soak the seaweed in order to obtain a pH of carrageenan that meets FAO standards.
