KAJIAN LITERATUR SIMULASI PENGARUH PENERAPAN UNDERPASS DI PERSIMPANGAN KENTUNGAN YOGYAKARTA TERHADAP BEBERAPA PERSIMPANGAN LAINNYA
No full textThe intersection of Kentungan is one of the intersections that connects North Ringroad Road and Kaliurang Street which looks increasingly stuck in Yogyakarta. This is due to an uneven increase in vehicle vehicles to road infrastructure. The peak of traffic jam at Intersection of Junction often occurs at 16.00-17.30 WIB. The problem at this junction is the amount of time delay and the length of the queue. One way to reduce congestion problems at the Intersection is to construct road infrastructure, one underpass. Based on these problems, research on the effect of underpass application on congestion parameters at several other intersections adjacent to the intersection of Kentungan. This research is a Multi Channel Multi Phase model configuration, by creating an underpass model of the Autodesk Infraworks 360 software. Before modeling underpass conditions, it is done in advance of the existing model of Intersection of Kentungan. The data inputted to this existing model is the total data of vehicles crossing the intersection of Kentungan for one hour. Verification model in this research is done by visual testing and check the duration of green light at the time of simulation done. Validation in this research is done by using hypothesis test, paired t-test. Then the parameters for validation are data ie the average waiting time of the vehicle, the maximum queue length and the number of vehicles passing through the green light in one cycle.In this study using two scenarios, in scenario 1 is the underpass model with the condition of the intersection and the scenario 2 is the underpass model with the roundabout condition. The results obtained from both scenarios are compared with the existing model results. The compared parameters are the average vehicle delay time and maximum queue length on each approach. It is expected from the comparison analysis to show that the Kentungan Intersection after the built underpass has decreased significantly on the average delay time and maximum queue length

Studi Parametrik pada Flapping-Wing MAV dengan Bentuk Sayap Belalang, Kupu-kupu dan Kumbang
No full textNature has been a great inspiration for engineering design. Flying insect, in specific, has been studied and being an inspiration in the development of flapping-wing micro aerial vehicle (FW-MAV). Each species of flying insect has its own wing kinematics, but most all of them generate the aerodynamic force with the same of three mechanism: delayed stall, rotational circulation and wake capture[1]. In this research, we conduct a parametric study on the FW-MAV with different wing shapes. There are two designs of the FW-MAV in this study, which have flapping angle of 80 and 120 deg. The three different shapes of wings are mimics from: desert locust, Monarch butterfly and rhinoceros beetle. The wings then attached to the FW-MAV and operated with voltage input of 1.5V. The force generated by the FW-MAV and the electrical current measured in a swing test, while recorded in 240 fps using action camera. From the test, we get the flapping frequency, generated horizontal force and power consumption. From this research we have several data that can be used for the further development of the FW-MAV
