Abstract
Chlorella sp. is one of the natural foods that are widely cultivated Chlorella sp. is one of the
natural foods that are widely cultivated, because Chlorella sp. can multiply quickly, easy to
cultivate, the whole organ can be utilized. Organic fertilizer that can be used as an alternative
fertilizer in Chlorella sp culture is cow feces which is one of the potential livestock waste for
Chlorella sp culture. This research conducted for 30 days in May 2022, at the Fish Hatchery and
Breeding Laboratory, Faculty of Fisheries and Marine of Riau University. The aimed of this
study to determine the effect of fertilizer application from fermented cow feces on the growth of
Chlorella sp. and knowing the best dose of fermented cow feces for the growth of Chlorella sp.
This study used an experimental method, while the experimental design used a completely
randomized design with 4 treatments, each with 3 replications. as for the treatment in this study
P0 (Walne fertilizer 1 mL//L), P1 (cow feces fermented 3.5 mL/L), P2 (fermented cow feces 5.5
mL/L), P3 (fermented cow feces 7.5 mL/L). The best fermented cow feces dose is 5.5 mL/L
culture media with population density the highest was 340.00 x 104 cells/ml and the specific
growth rate was 0.29 cells/day and the highest density peak occurred on the 9th day. Water
quality during the study was in the optimum range, namely temperature with a value of 28.10C -
29.90C, pH during the study was 6-8 and DO 4 - 5.9 mg/L.
