Macroalgae is photosynthetic organisms that live in watery environments, especially in the sea. Macroalgae has various types of chlorophyll depending on the types, including chlorophyll a, b, c, and d. One of the dominant pigments in red seaweed is phycobilin which consists of phycoerythrin, phycocyanin, and allophycocyanin. Macroalgae is abundantly found in the intertidal zone of the south coast of Gunungkidul; however, there are still few studies on the macroalgae potency. This research aimed to determine pigment concentration of macroalgae in the south coast of Gunungkidul, Yogyakarta in order to understand the potency of macroalgae pigments for small to industrial purposes. The method used is spectrometry, then analyzed by the formula.The result of this research, it was found that from three species were abundantly found in south coast of Gunungkidul, Ulva lactuca has concentration of Phycobilin pigment like Phycocyanin 0,005 mgml-1, Allophycocyanin 0,112 mgml-1 and Phycoeritrin 0,027 mgml-1 also Chlorophyll a 0,022 mgg-1 and Chlorophyll b 0,026 mgg-1. Padina minor has concentration of Phycobilin pigment like Phycocyanin 0,088 mgml-1, Allophycocyanin 0,270 mgml-1 and Phycoeritrin 0,033 mgml-1 also Chlorophyll a 0,026 mgg-1 and Chlorophyll b 0,028 mgg-1. Gracilaria textorii has concentration of Phycobilin pigment like Phycocyanin 0,027 mgml-1, Allophycocyanin 0,112 mgml-1 and Phycoeritrin 0,008 mgml-1 also Chlorophyll a 0,019 mgg-1 and Chlorophyll b 0,007 mgg-1. |
