EKSPLORASI SPESIES ALGA COKELAT LOKAL LOMBOK SEBAGAI SUMBER KARAGINAN
ABSTRACT: Seaweed known as a
producer of hydrocolloid compounds, including carageenan , an important raw
material for many industries. Therefore, knowledge on the carageenan producing
seaweeds is quiet important to support the carrageenan production in Indonesia.
This article reports the carageenan content of local strains brown algae.
Research was conducted by collecting all species of brown algae grow in Lombok,
drying, extracting its carageenan using ethanol and isopropanol methods.
Results showed that the carrageenan content of these species around 0,75
(Turbinaria ornata) - 6,92% (Dictyota sp.1). Unfortunately, these values are
lower than that of the minimal carageenan content recommended by Indonesian
Trade Department. The carrageenan content of these strains was not
significantly different either extracted by ethanol or isopronol method. It is
suggested that these strains are not carageenan producing seaweed. It needs
further study to understand the type of hydrocolloid compound produced by brown
algae species.
