ABSTRACT
Iodine content of seaweed species Lato (Caulerpa lentillifera), Guso (Eucheuma spp.), and Gulaman (Gracilaria compressa), in three replicates were analysed by titration, using Standard Sodium Thiosulphate as the titrant. This study resulted that Gulaman (Gracilaria compressa) yields the highest iodine content with 6.1986 mg/g next is Guso with iodine content of 4.9376 while Lato (Caulerpa lentillifera) having the lowest iodine content with 4.6264 mg/g. One-Way Analysis of Variance (ANOVA) at 95% level of confidence (a0.05) showed that there is a significant difference between the iodine content of Gulaman from the other two species, Lato and Guso, which are not significantly different from each other in terms of iodine content. *mg/g = milligrams of iodine per gram of dried seaweed used in each replicate of each species.
