TEST CHARACTERISTICS OF THE TURBINE SAVONIUS 4 LEVELS SECTIONAL, PARTITIONED, 0.25 DIAMETER OVERLAP AND 45o SLIDING ANGLE WITH COMPARABLE STANDARD TURBINE

ABSTRACT: The  energy  and  environmental  crisis  where  CO2  causes  global  warming  and  climate  change.  This condition encourage the world community take advantage of new renewable energy non-CO2 as wind, water currents, geothermal, solar, etc. Savonius Turbine has a simple construction can be made by the public  so  they  can  be  used  for  wind  power  or  hydro  countryside.  In  this  study  aims  to  improve  the efficiency and reduce the amplitude of vibrations to the modification of the 4-storey Savonius turbine, partitioned,  sliding  angle  45  degree  and  0.25  diameter  blade  overlap.  The  location  of  research  is Cokro  Tulung  Channel  Klaten  and  Parangrucuk  Baron  Beach  Gunungkidul.  Measurements  such  as water  current  and  wind  speed,  turbine  rotational  speed,  torque  of  the  turbine  shaft  and  power.  The turbines  analysis  are  torque,  power  and  efficiency  characteristics  and  comparing  by  the  turbine Savonius standard (one pair of blades). Results as hydro turbine at low velocity 0.3166 m/s Savonius 4 level had better revolution and efficient (0.0826) than 1 level (0.024), but as wind turbine at 3.056 m/s velocity the Savonius 4 level had worse efficiency (0.039) than 1 level (0.025) because the inertia load.  
Keywords: Savonius, efficiency, torque, 4 levels, sliding angle 45o
