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.

采用结构化线段取样和象限定位方法,对梅拉斯水域的藻类多样性及其丰度进行了研究。研究结果表明,藻类的香农指数(H')高于 1.75。这表明,在水质条件仍然适合藻类生长的地方,藻类种类的多样性是适中的。使用 TEM 对藻类细胞结构进行分析的结果也证实了这一点,该分析结果发现了弗洛里达淀粉的存在,这证明了光合作用过程正在这些水域中进行。藻类在生长发育过程中会进行光合作用。发现的 9 种藻类分布在 3 个类别中,即 3 种叶绿藻、4 种藻类和 3 种红藻。物种丰度分析结果表明,这些水域中的藻类物种数量最多,为 7.6 个/平方米,相对丰度为 0.28。叶绿素 a 为 359.335 微克,叶绿素 d 为 47.385 微克,胡萝卜素色素为 1627.75 微克。这种藻类色素可用作食品(营养)和制药工业的原料。关键词藻类类型、色素和细胞结构的多样性 Abstrak Penelitian Keanekaragaman jenis alga dan kelimpahannya di perairan Meras telah dilakukan dengan metode pengambilan sampel line transek dan peletakan kuadran secara terstruktur.藻类生长指数香农指数(H')为 1.75,表明藻类生长指数在藻类生长过程中的作用。通过对藻类的结构进行分析,我们可以得出结论,藻类中的淀粉含量会增加,从而影响藻类的光合作用。而藻类中的淀粉含量较高,因此也会影响照片检测的结果。目前发现的藻类有 9 种,分布在 3 个领域,即叶绿藻类 3 种、真叶藻类 4 种和红藻类 3 种。对这些藻类进行的藻类数量分析表明,水螅藻的藻类数量为 7.6 个/平方米,藻类数量相关系数为 0.28。藻类中的色素照片分析结果显示,氯硅烷 a 为 359 335 微克,氯硅烷 d 为 47 385 微克,而色素 k 则为 1627 75 微克。藻类颜料可作为食品工业(营养品)和养殖业的主要原料。相关信息 :藻类、色素和硒的结构。
