Abstract

The rapid advancement of electric vehicle technology has created a growing necessity for chassis structures that are robust, weight-efficient, and engineered to meet stringent safety standards in order to optimize the performance of eco-friendly racing vehicles. This research was conducted to assess the structural integrity of the chassis in an Electric Vehicle Race Car when subjected to static load conditions. The analytical approach adopted in this study is the Finite Element Analysis (FEA) method, utilizing Autodesk Inventor software as the primary simulation tool. Two distinct load scenarios were applied during testing, specifically 70 kg and 100 kg, to obtain output values of Von Mises Stress, Displacement, and Safety Factor. The simulation outcomes revealed that both the Von Mises Stress and Displacement values remained within the permissible safety threshold of the selected material, while the Safety Factor value successfully surpassed the minimum design benchmark. Consequently, the chassis developed in this study is deemed to possess sufficient structural strength and rigidity, confirming its suitability for implementation in electric-powered racing vehicles.

Abstract

This research was motivated by the students' lack of active participation and low cognitive learning outcomes in understanding Orthogonal Projection concepts. The root of the problem stemmed from the dominance of conventional instructional strategies that neglected the use of physical visual aids. Therefore, this study was conducted to determine the effectiveness of implementing Problem-Based Learning (PBL) integrated with 3D Printing technology in improving students' active participation and learning outcomes. The research applied a Classroom Action Research (CAR) approach adapting the Kemmis and McTaggart model, executed in two cycles. The participants included 40 students of class X TO 2 at SMKN 1 Kota Sukabumi. Data were analyzed using quantitative descriptive techniques, percentage calculations, and the Normalized Gain (N-Gain) metric. The findings demonstrated consistent positive progress. Classical student learning participation gradually increased from 64% (Poor category) in the pre-cycle to 89% (Active category) in Cycle I, and reached 93.16% (Very Active category) at the end of the intervention in Cycle II. This success was accompanied by an increase in cognitive achievement, where the classical completeness rate successfully reached 58% in Cycle I from an initial 13%, and culminated at 85% (Good category) in the second cycle. The N-Gain analysis confirmed the effectiveness of the intervention with a score of 0.74, categorized as high. In conclusion, the application of the 3D Printing-assisted PBL model significantly resolved students' passivity in the classroom and improved their learning outcomes in Orthogonal Projection materials.
