The national electrification ratio is only 72.95%. As many as 27.05% of the territory in Indonesia has not been reached by electricity with various obstacles, one of which is because of the remote location so that access is difficult. One of the efforts to overcome the electricity problem is to take advantage of the potential energy sources around people's residences. One potential that might be used is a water energy source with low head and discharge. Ideally, this is done by using a generator system that uses a propeller type turbine. The difficulty of making propeller turbines is especially in the manufacture of housings and turbine blades. In this research, an attempt is made to simplify the turbine housing and turbine blades so that they are easy to manufacture. The design is made for Head (H) : 5 m Water flow (Q) : 0.11 m3/s Viscosity (ρ) : 998 kg/m3 Gravity (g) : 9.81 m/s2 Assumed hydraulic efficiency (ηh) : 0 ,80 Power (P) : 4,37 kW, Angle of attack (180o-β∞) 16o, Glide angle 55o, Thickness of inner blade(λ) 2,16o, Thickness of outer blade(δ) 2o. Simplification of the turbine housing is carried out by making the turbine housing from pipe iron and the simplification of the turbine blade is carried out by making turbine blades by eliminating the aerodynamic cross section of the blades, so that the blades can be made of steel plates without casting as is treated in aerodynamic sections. To see the effect of aerodynamic and non-aerodynamic cross-sectional shapes on efficiency, an efficiency test will be carried out.

PT. Kurnia Batang Hari is a palm oil processing factory into palm oil. At PT KBHB there is a tool called “Steam Turbine Generator Type RB5” which functions as a power generator. This study aims to determine the effect of the load on the mass flow rate, turbine generator power, and determine the efficiency of the steam turbine generator. The research method is to take boiler and turbine data directly for 1 week. Get the enthalpy value from the steam table and can calculate based on the research objective. Based on the research conducted, it was found that the highest average flow rate on Wednesday was 3.48 kg/s. The highest generator power yield on Sunday is 1661 KW. The results of the calculation of the highest average generator efficiency on Sundays are 57.11%. Conclusion It can be seen that if the load on the turbine is getting bigger, then the mass flow rate of the steam will be even bigger and it also depends on the pressure of the steam entering and leaving the turbine. The average load of 1 week borne by the generator is 885 KW and the mass flow rate is 3.81 kg/s. The generator power produced during processing is an average of 1 week, which is 1600 KW. The average efficiency of the generator in 1 week is 55.52% on Sunday.
