This study aims to determine the biodiversity of microalgae in the Gili Meno Saltwater Lake. The type of exploratory descriptive research was conducted in April-June 2025. The sampling method uses a random sampling method taken at 9 different points. The results showed that as many as 21 species of microalgae were successfully identified from 9 sample points, consisting of 5 phyla and 5 dominant classes. The results of the analysis showed the value of the Shannon-Wiener diversity index (H') of 1.981, the uniformity index (E) of 0.63, and the dominance index (C) of 0.209. The highest INP value is owned by Chrococcus turgidus (49.41). The microalgae communities in Salt Water Lake are dominated by pollution-tolerant groups. This confirms that the condition of the aquatic ecosystem at the research site is in the moderately polluted category.
