The availability of fossil energy sources is increasingly limit because of uncontrolled use, so alternative energy to substitute a fossil energy, one of them is solar energy. Solar energy used as a heater or drier, as a solar air collector. Solar air collector is one of the heat exchangers that converts solar energy into heat energy. The performance of the solar heater air collector can improved in several ways, namely changing the shape of flat plate to v-corrugated absorber and adding fin to expand the heat absorption area and adding an obstacle to creating turbulence. Fin which used is a half cylinder with a diameter of 6 mm and the angle of 67.5o towards the direction of the working fluid flow under the absorber plate. The obstacle that used as a working fluid disruptor to obtain turbulence flow by giving a straight triangle bent 30o. The highest Qusefull experimental results on the v-corrugated absorber plate with a mass flow rate of 0.08 kg/s with a radiation intensity of 876 Watt/m2 which is equal to 785.80 Watt. The highest efficiency at the radiation intensity of 654 Watt/m2 with a mass flow rate of 0.06 kg/s which is equal to 87%.
