Abstract

Frame is the very important of vehicle. Design of the right frame will provide optimal results between the level of security and the size of the construction. To get an energy-efficient car, it is necessary to design a car frame that fits your needs. From the design carried out based on the body shape of the vehicle, a construction structure of the Asykar Hybrid is Monocoque type frame by using a profile of rectangular hollow section by 30 mm x 50 mm x 2 mm and angel L section 50 mm x 50 mm x 3 mm and dimensions overall frame with a length of 2456 mm x width 932 x height 920 mm. Static analysis calculate by Autodesk Inventor 2018 Student Version software which produces a Principle Stress on the main stem of 46.99 MPa and displacement of 6.005 mm. The results of the manual calculation of the main Principle Stress are 56.94 MPa with a Shear of 28.47 MPa. Safety factor of 4.39 by using Carbon steel ST 37 material. So it was concluded that the framework of energy-efficient cars is safe to use.Keywords: Frame, Principle Stress, Deformation, Energy Saving

Abstract

E-waste is a waste in the form of electronic devices that are not used anymore. One example is the personal computer components (PCs) that have been damaged or already left as an old technology that it can be no longer used. So far, e-waste PCs have not been widely used or recycled for more useful purposes, so its existence tends to be a waste that has the potential to cause pollution. Based on these conditions, it is necessary to do a research for e-waste PC can be processed and reused, one of which can be used as machine prototype computer numerical control (CNC) with three axis which can then be used as a medium for studies. This research begins by designing the physical form of a 3 axis CNC machine with the software Autodesk Inventor device. Then, it was made a prototype machine that part of its components taken from the former PC unused components. As a driving force, the prototype CNC machine used stepper motor combined with Arduino UNO Microcontroller based control system. This machine is then operated with a PC using Universal G-Code Sender and GRBL (Coding Gate) based CNC programming system. With a working area of 42 mm x 42 mm and a 17 mm depth of feed, the prototype CNC machine can eventually be used as a study medium for schools that do not have CNC machines due to their high cost and high maintenance costs.
