Toba Lake is a lake that is used as aquaculture land. Floating net cageactivities in the Toba Lake has been done by the public since 1986, but the rapiddevelopment of floating net cage occurred since 1998 through the intensive cultivationnet high fish density. This study aims to analyze potential areas for floating net cage iniToba Lake Girsang Sipangan Bolon, Simalungun by the suitability matrix method. Thisresearch use the scorring method/weighting. Determination of weighting and scoring isdone to put a value on criteria that support the aquaculture activities by linking thechemical physical parameters. These parameters include temperature, DO, pH,brightness, current, depth, BOD, and ammonia. The results showed that thesuitability grade in Toba Lake Girsang Sipangan Bolon is very suitable and suitableclass. This shows that Toba Lake Girsang Sipangan Bolon is a potential area forfloating net cage.Keyword : Toba Lake, Floating Net Cage, Suitability Index
