Abstract

The study aims to find out how to get start in fabricating Banki turbine of 200 watt in electical power capacity and determine the influence of fixed blade opening and dynamometer loading variation. This study was performed and examined directly in the laboratory of University of Muslim Indonesia Makassar, turbine rotation velocity, water capacity, were measured using hand tachometer, and manometer respectively. The fixed blade valve setting also performed during the test.The result of study show that fixed blade opening with load variation at constant rotation turbine produced maximum power as follows: fixed blade opening of 12o with 2 kg load in 550 rpm produced 72 watt of electrical power and maximum fixed blade opening of 20o with 5.2 kg load in 550 rpm produced 186 watt of electrical power.

Abstract

Driving comfort for riders and passengers is a keytarget to be achieved. Fluctuations in vehicle loads, bumps,perforated surfaces, and other road damage will greatly affectthe vehicle suspension working system. This study aims tocalculate the vertical dynamic load of the vehicle actually whichoccurs on road construction after through the vehicle wheelsuspension mechanism. The Pneumatic cylinder that was drivenby pressurized air directly weigh on the spring and ShockAbsorber that contained on the wheels of the vehicle. The loadfluctuations of the medium weight category vehicle aredetermined by the regulation of the amount of pressurized airentering into the pneumatic cylinder chamber pushing the pistonand connecting rods. The deviation that occurs duringcompression on the Spring and Shock Absorber, is substitutedinto the vehicle dynamic load equation by taking also themagnitude of the spring stiffness constant, and the fluid or gascoefficient of the damper. The results showed that the magnitudeof the displacement when the compression force worked hassignificantly influenced the amount of vertical dynamic load ofthe vehicle that overlies the road construction. Experimentalresults using pneumatic actuators instead of real dynamic vehicleloads illustrate the characteristics of the relationship betweenwork pressure and dynamic load. If the working pressure of P2(bar) is given great, the vertical dynamic load Ft (N) whichoverloads the structure of the road is also greater. From thegraph shows that shock absorbers have greater ability to reducedynamic load vertically when compared to spring ability.

Abstract

Potensi pemanfaatan energi matahari sebagai sumber energi alternatif, saat ini kebutuhan energi terbarukan semakin meningkat dan sinar matahari merupakan sumber energi yang sangat melimpah. Alat yang dapat digunakan saat ini untuk mengonversi secara langsung cahaya matahari menjadi listrik disebut photovoltaic. Pada penelitian ini diujikan 2 buah photovoltaic module kapasitas 50 WP dengan perbandingan photovoltaic module berpendingin dan tidak berpendingin terpasang pada posisi yang tetap/horizontal terhadap bumi dengan sudut kemiringan 15°, Hasil pengujian menunjukkan bahwa perubahan intensitas cahaya matahari diikuti dengan kenaikan daya dan efisiensi. Daya maksimal yang dicapai yaitu pada pengujian menggunakan media air pendingin sebesar 36,5 Watt dengan Efisiensi 10,96 % sedangkan photovoltaic module tidak berpendingin daya maksimal yang diperoleh 30,2 watt dengan efisiensi 8,51 %  terukur pada kondisi waktu yang sama pada pukul 12.00 WIB.
