Abstract

Fossil energy is a limited and non-renewable source of energy, therefore it is necessary to look for alternative energy solutions that are not available and can be updated. Another reason is to reduce the impact of pollution caused by the use of fossil energy. As we all know, the biggest source of pollution in the world comes from exhaust gas/fossil fuel emissions. These plants can convert wind energy into electrical energy using wind turbines or windmill. The electricity generation system using wind as an energy source is an alternative system that is very rapidly developing, considering that wind is an energy that is not limited in nature. The purpose of this study was tested using three blades, varying the diameter with a slope of 150, namely to determine the effect of blade diameter on the power produced by the turbine and the efficiency of the horizontal shaft wind turbine. The turbine power testing method is done manually by using 2 spring balance which is associated with the belt, v-belt, then the v-belt is associated with an 8 cm diameter pulley that is on the turbine shaft, the friction between the belt and the pulley is ignored. From the test results, the torque produced by the turbine is carried out in a certain rotation. Wind turbines made with blade blades 2 m, 2.40 m, 2.80 m with wind speeds of 4 m / s From the three turbine blade variables based on testing different turbine blade diameter the resulting power is different, from the test results it can be known the power generated by the power turbine can be seen that the highest power on the blade diameter is 2.40 m at 140 turns (rpm) with turbine power of 19.9606 watts, with an efficiency of 10,6263 % and the lowest in blade diameter 2m in rotation 120 ( rpm) with turbine power of 12.9374 watts, with an efficiency of 9,9579 %.

Abstract

Aluminum is one of the non-ferrous metals that are most widely used in the engineering field due to it has mild properties and is resistant to corrosion, but aluminum waste such as used pistons that are damaged or not utilized as an proper resource, on the other hand, that this process is very potential due to it uses a used piston that is not used, and is expected to have a better economic value by doing remelting and centrifugal casting to the used piston. This study aims to determine the value of the fatigue cycle of the used piston which is remelting and printed using the centrifugal casting method by using variations in the pouring temperature and die temperature and rotation variations. Based on the tests conducted using pouring temperature variations and rotation speed are as follows: best cycle value at 250 rpm variation is at pouring temperature 600oC with a value of 76000 N, and the lowest is at room temperature of 750oC with a value of 32000 N, best cycle at a variation of 500 rpm is at a pouring temperature of 700oC with a value of 40000 N, and the lowest is at a room temperature of 660oC with a value of 12000 N. The best cycle value at a variation of 750 rpm is at a pouring temperature of 750oC with a value of 16000 N, and the lowest is at room temperature 660oC with a value of 10000 N. While the results of subsequent tests conducted using variations in die temperature and rotation speed are as follows: the best cycle value at 250 rpm variation is at a print temperature of 350oC with a value of 17400 N, and the lowest is at room temperature of 250oC with a value of 8370 N. The best cycle value at a variation of 500 rpm is at a print temperature of 350oC with a value of 67760 N, and the lowest is at a room temperature of 250oC with a value of 22850 N. The best cycle value at a variation of 750 rpm is at a print temperature of 350oC with a value of 75170oC. and the lowest is at room temperature of 250oC with a value of 28940 N.Keywords: Centrifugal casting, fatigue test, remelting, used piston, aluminum, cycle value.Barbarslot adalah salah satu situs resmi slot deposit 5000, 5rb dan depo 5k terbaru dengan beragam permainan terbaik tahun 2025.
