【 摘 要 】

Lake Toba is the largest lake in Indonesia located in Toba Samosir regency, North-Sumatera. The lake is currently facing serious habitat exploitation due to anthropogenic activities in surrounding area. Effort to identify and assess the quality of freshwater bodies are conducted through assessment upon phytoplankton diversity. The aim of study was to identify the phytoplankton diversity at Situmurun village. The village is one of rural area in Toba Samosir regency, known as tourism spot for its Binangalom waterfall. The freshwater area of this village is still considered natural and free of human activities. List of phytoplankton taxa is presented. The study found 5 classes of phytoplankton grouped into 28 families with 33 species. Our result will be compared with overall phytoplankton diversity for assessing biological-based water quality in Lake Toba.
