Abstract

The technology that can be developed from Unmanned Aerial Vehicle (UAV) in agriculture is the Unmanned Aerial Vehicle Eagle-X. This technology can help farmers in carrying out their daily activities to repel bird pests on agricultural land. However, people have difficulty understanding how to use UAVs. So, with this simulation, it is hoped that it can help farmers and producers understand the workings of the eagle-x aircraft. The simulation is made using 3Ds Max software which functions to create all 3D objects and also uses Unity software to create animations and simulations. This simulation can run well on a PC or laptop that has a Windows 10 operating system with 64bit and a minimum of core i-3 specifications.  Trials using simulations were carried out on 30 farmers and the results showed that 86.67% of farmers stated that this simulation was effective in providing an overview of how the Unmanned Aerial Vehicle Eagle-X works in repelling sparrow pests.

Abstract

The Glider Eagle-X aircraft is an unmanned aircraft which is expected to fly with a height of 7 meters above the ground in Yogyakarta (120 m above sea level) with a flying speed of 10 m/s. In order for the Eagle-X glider to fly stably, it is necessary to analyze the flight stability of the Eagle-X glider model. Therefore, in this study, the analysis phase of static stability and dynamic response of disturbances in the longitudinal dimension was carried out. This can be useful for students so that they can better understand the analysis of static stability and dynamic response of disturbances in the longitudinal dimension. The results of the analysis show that the flight dynamics is a value of CM-α < 0 indicating the plane is statically longitudinal and the initial response of the graph is getting smaller which indicates the plane's motion is dynamically stable. The output of the stability analysis of the flying dynamics of the Eagle-X glider model is in the form of a graph. The simulation of the flying dynamics of the Eagle-X glider in the expected longitudinal dimension is shown by the aircraft movement following the graph from the results of the stability analysis which is used as the path of the Eagle-X glider model.

Abstract

The main purpose of aerodynamics analysis of a vehicle is optimizing it’s form to increase aerodynamics efficiency. More streamline of aerodynamic design of a vehicle not just effecting to lower fuel consumption which is cause by lower drag due to wind at highspeed, but also increasing stability dan control of the vehicle itself. The vehicles are existed with many variations of form so they have difference aerodynamic characteristics. For a personal vehicle like cars, have many variants such as sedan, sport utility vehicle (SUV), multipurposes utility vehicle (MPV), ect. It becomes a motivation to do research about aerodynamic analysis of a SUV car which is a car variant with huge utilize in Indonesia. In this research, aerodynamic characteristics of SUV car are evaluated by computational simulation with computational fluid dynamics (CFD) approach. CFD simulation yields aerodynamic characteristics data and flow behaviors around car model. Simulation results show that critical drag coefficient (CDcrit) of SUV car is 0.36 with lift coefficient is 0.25. the CDcrit of the car is lower than typical value for a modern car. So that, optimalization of SUV car form which analyzed is needed. Contours of pressure at car surfaces show that high pressure area are located at front of grill and windshield, and low-pressure area are located at nose and leading-trailing roof due to the form nose and leading-trailing roof are streamlines. At back surface of the car, low pressure area are formed by flow separation which creates wake.

Abstract

Entrepreneurship is one of the main focuses of Karang Taruna’s activities in an effort to improve community welfare. Karang Taruna in Jaden Village, Mranggen, Jatinom, Klaten, offers a variety of programs that the community can participate in. However, aeromodeling has not yet been included as part of the development activities in Karang Taruna of Jaden Village, Mranggen, Jatinom, Klaten, due to a lack of knowledge and information about aeromodeling, even though Klaten is very close to the Adisutjipto Airport and the Indonesian Air Force Base, both of which frequently hold aeromodelling events and activities. A training program on making simple aeromodelling planes, such as foam chuck gliders, could become a source of independence and a foundation for further understanding of aeromodelling, which has the potential to develop into a wider business field. In this training, the OID (Observe-Imitate-Do) method is applied to accelerate and strengthen the learning process. The results of the training demonstrate the effectiveness of the activity through indicators such as: participants showing great enthusiasm in following the entire program, as evidenced by their active participation and high level of involvement in all activities, the application of the OID method providing effective and comprehensive learning experiences for the participants, and the training successfully sparking participants’ interest in exploring entrepreneurship.
