Abstract

Coastal areas have potential that can be developed by the community, one of which is beach tourism. Tourism activities around that take place around the coast can affect the aquatic ecosystems especially the community structure of phytoplankton. Phytoplankton are aquatic organisms that act as primary producers. Bacillariophyceae is a class of phytoplankton that is commonly abundant in marine waters. The objectives of this study were to determine the species composition, species abundance, and community structure of Bacillariophyceae in the waters of Klui Beach. This type of research is descriptive-explorative. The Haphazard sampling was applied for determining the sampling sites. Phytoplankton data were analyzed using the abundance formula, diversity index, uniformity index, and dominance index. The results showed that the composition species of Bacilllariophyceae consisted of 48 species which included in 17 orders. Average species abundance was 298.09 ind/L (low category). The spesies diversity index was 2.37 (moderate category), the species uniformity index was 0.86 (high category), and the species dominance index was 0.13 (low category).

Abstract

Klui Beach is one of some famous beaches tourism destination in the Northern part of Lombok Island which is commonly visited by many tourists. Tourisms and resindents activities that take place around the coast can produce various wastes that have some prominent impact on pollution, for reducing water quality. Bacillariophyceae is a class of phytoplankton that is commonly abundant in marine waters and can be used as an indicator for controlling of water quality. The objectives of this study were to determine the level of pollution in the coastal waters of Klui Beach based on the Bacillariphyceae diversity index. The Haphazard sampling was applied for determining the sampling sites. The results showed that the composition species of Bacilllariophyceae consisted of 48 species which included in 17 orders. Average species abundance was 298.09 ind/L (low category). The spesies diversity index was 2.37 (moderate category). The level of water pollution in the Klui Beach was classified as not polluted.
