The research was conducted in January to March 2017, located in the
village of Qualu Nenas, Tambang Subdistrict, Kampar District, Riau Province.
Phytoplankton observation was conducted in Environmental Quality Laboratory
of Cultivation, Faculty of Fisheries and Marine University of Riau. Method this
research using a Complete Randomized Design (CRD) was one factor with 4
levels of treatment. The kinds of using are P0 (without giving the vermicompos),
P1 vermicompos from human feces (0,615 kg m-2), P2 vermicompos from cow
feses (0,615 kg m-2) and P3 vermicompos from chicken feses (0,615 kg m-2).
The best of treatment of this research was the P1 vermicompos from human feces
(0,615 kg m-2). Phytoplankton abundance this treatment is 17.520 individu/L,
rather than of the other treatment. The water quality parameters in this research is
good, especially of temperature 27-32 0C, pH 3.6-6,8, dissolved oxygen 2,0-
3,3mg/L, nitrate 4.66-10,44 ppm and orthoposfat 2,50-6,76 ppm. refering for the
Quality Standart of Aquaculture.
