More than 17% of people in remote areas of Indonesia still do not have electricity. With the abundance of water potential in Indonesia, hydro pico is consideredas the right solution because it has cheap investment and operational cost. The breastshot waterwheel is a suitable turbine that can be applied because it does not affect the garbage in the water. Characteristic of the breastshot waterwheel especially effect of bucket numberon performance have been study in this paper. CFD method isused to evaluate the flow field and explain the effect of the number of the buckets on the waterwheel performance qualitatively. The turbulent model used is k-ϵ. Simulations were performed with the number of buckets 11, 12, 13, 14 and 15. Analysis using ANOVA block design explains that there is a relationship between the number of buckets to the generated power (F0 > F0.01,2:8). From the analysis, the wheel with the number of bucket 13 produces more stable power than other buckets. This is because the shape of the radial blade is not so steeply upward that the weight energy of water and kinetic energy can be utilized maximally.
