Phytoplankton Abundance in the Coastal Waters of Apar Village, Pariaman City, West Sumatra

ABSTRAK

Apar Village, located in Pariaman City, is home to a mangrove forest ecosystem that plays a crucial role in maintaining water quality and providing natural spawning grounds for various marine organisms. Phytoplankton serve as important bioindicators of aquatic environmental conditions because they are primary producers and major contributors of oxygen in aquatic ecosystems. This study aims to identify the composition and abundance of phytoplankton and their relationship with nutrient concentrations, particularly nitrate and phosphate. The research employed a survey method with direct field sampling for primary data and a literature review for secondary data. The results revealed 22 phytoplankton species from four main classes, with Bacillariophyceae (diatoms) being the most dominant, comprising 17 species. Phytoplankton abundance ranged from 361.11 to 479.17 individuals per litre, while nitrate and phosphate concentrations ranged from 0.058 to 0.085 mg/L and 0.047–0.072 mg/L, respectively. Regression analysis indicated that nitrate and phosphate accounted for 21% of the variation in phytoplankton abundance. In comparison, the remaining 79% was influenced by other environmental factors yet to be studied, such as temperature, salinity, and light penetration. Based on the abundance and nutrient concentration data, the waters of Apar Village are categorized as having low fertility, with indications of phosphate enrichment likely resulting from anthropogenic activities. This study recommends further research incorporating additional water quality parameters and encourages active community participation in preserving the balance of coastal ecosystems
