Abstract

Limboto Lake is a natural resource owned by Gorontalo Province at this time. Limboto Lake has a role
as a source of income for fishermen, flood prevention, sources of irrigation and tourism objects.
Limboto Lake is now in a very alarming condition because it experiences a process of shrinkage and
siltation due to sedimentation and organic matter accumulation due to the increasing number of fish
farming in floating net cages. The decreasing area of lake waters causes the decline in lake function
as a place to live aquatic organisms. Eutrophication and pollution that occur is a result of the
introduction of organic material into the waters which exceeds the carrying capacity of these waters
which indirectly affects the source of income of KJA farmers. Making a suitability matrix for determining
water zoning is then analyzed through Arcgis software. Based on the results of the study, the
appropriate land area is 6.2 ha and the land area is not suitable, which is 2871.24 ha. Floating Net
Cages that can be accommodated by the carrying capacity of the waters in Lake Limboto are 496 KJA
units, with a KJA size of 5 X 5 m and a distance between KJA of 5 meters. Undertake alternative
livelihoods such as making / printing ponds on unproductive land on the shores of Lake Limboto that
are in accordance with the designation. Cultivate tarpaulin ponds because they do not require large
land and lots of water.
