Abstract : The provision of inexpensive renewable power generation systems is a good alternative in supplying electricity in various regions. This study examines the financial feasibility of a design with variations in discharge and head for a micro hydropower plant (MHP) in an off-grid management area in villages in Jember Regency. The development of these 4 cases uses 2 MHP locations that are simulated with turbine variations, then their feasibility and sensitivity are analyzed to get the optimal design. By changing the turbine to be more efficient, the percentage increase in NPV and IRR in cases 1 and 2 is greater than in cases 3 and 4, with an increase in NPV of 15.18%, IRR by 8.12%. On the other hand, the percentage increase in BCR in cases 1 and 2 was slightly smaller than in cases 3 and 4 with a value of 4.32%. These results can be used as a reference in determining the location of the MHP and turbine type preferences.
