Preliminary Study the Potency of Macroalgae in Yogyakarta: Extraction and Analysis of Algal Pigments from Common Gunungkidul Seaweeds

Study on pigment for industrial purposes becomes a fascinating area so motivates the exploration of pigment resource candidates. The research aimed to get preliminary data about types of macroalgal pigment which were possibly produced by Gunungkidul seaweeds. Research conducted in March, 2013 in Porok Beach, Gunungkidul to selected seaweed samples. Pigment extraction was done using spectrophotometric method to determined non polar and polar pigments. The results showed common seaweeds in Gunungkidul which member of Chlorophyta had chlorophyll a, chlorophyll b, and carotenoid whereas Rhodophyta contained chlorophyll a and phycoerythrin.
