Chassis is the most important part of the vehicle. The purpose of the Chassis is to get optimal results between the size of the Chassis and the level of Safety Factor that is qualified in order to support the needs of the prototype "Warak" The chassis is designed using a ladder frame type frame design because this type is simple but sturdy to support the load. Design chassis uses Software Autodesk Inventor 2023 to get optimal results and uses Square Hollow Aluminum 6061 type material. The use of the Frame analysis feature which is equipped with the Finite Element Analysis (FEA) method plays an important role in knowing indications of discrepancies in the prototype that has been designed in the form of VonMises Stress, Displacement, and Safety Factor. After going through the design stage, the overall dimensions of the prototype "Warak” Stress Analysis obtained the maximum stress of Von Mises Stress which occurred in the chassis of 192.408 MPa. While displacement the maximum chassis is 1.7401 mm and the safety factor obtained from the analysis is a minimum of 1.08.
