Abstract

IELTS (International English Language Testing System) is a standardized English proficiency test which is a prerequisite for continuing study or work This workshop aims to assist the engineering faculty in its efforts to improve the mastery of English for new graduates which is designed and oriented towards mastering English with IELTS equivalents. This activity lasted for 3 days, from 28 to 30 August 2020. There were 20 (twenty) participants consisting of new graduates from the Hasanuddin University engineering faculty. Overall, the activities are expected to run smoothly and enthusiastically follow the Workshop process from beginning to end. The success of this program can also be seen from the achievement of predetermined success indicators, namely the number of participants who attended the workshop and the pre-test as expected, which exceeded 80% and 50%.

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.
