| Abstract |
Research on the diversity of algae types and their abundance in Meras waters has been carried out using structured line transect sampling and quadrant placement methods. The result is a diversity of algae types with a Shannon index (H') above 1.75. This shows that the diversity of algae types is moderate where water conditions are still good enough for algae growth. This is reinforced by the results of analysis of the structure of algal cells using TEM which found the presence of Floridian starch as evidence of the photosynthesis process taking place in these waters. When algae to grow and develop will carry out the process of photosynthesis. There were 9 species of algae found spread across 3 classes, namely 3 species of Chlorophyceae, 4 species of Phaeophyceae, and 3 species of Rhodophyceae. The results of the analysis of species abundance in these waters show that the algae species Gracilaria edulis is the most abundant, namely 7.6 individuals/m2, while the relative abundance is 0.28. The results of the analysis of photosynthetic pigments in the algae Gracilaria edulis were chlorophyll a, namely 359.335 µg, chlorophyll d 47.385 µg, and 1627.75 µg of carotene pigment. This algae pigment can be used as a raw material in the food (nutrification) and pharmaceutical industries. |
