Abstract

The development of electric vehicles today is not only focused on energy efficiency, but also on user comfort and safety. The 2kW BHARATA electric car, as one of the innovations of light electric vehicles, is designed to meet the needs of environmentally friendly mobility. However, ergonomic design is an important factor in preventing musculoskeletal disorders (MSDs) that are often experienced by vehicle users. This study aims to evaluate the ergonomic aspects of the driver's cabin design of the 2KW BHARATA electric car using the Rapid Upper Limb Assessment (RULA) method. The main problems in this study include: (1) how to apply the RULA method in analyzing the risk of discomfort or potential injury due to the driver's work posture, and (2) how the effect of variations in the angle and length of the driver's body posture on the level of comfort and risk of injury in the vehicle cabin. The research method used is a descriptive quantitative approach. The cabin design process was carried out using SolidWorks 2017 software, while the ergonomic analysis was carried out through simulation on CATIA V5 software. The simulation subjects were individuals with a height of 170 cm. The data obtained were analyzed to determine the ergonomic risk score based on the indicators in the RULA method. The results of the analysis show that the final RULA score is 4, which is included in the moderate risk category. This score indicates that the driver's working posture still needs adjustment to reduce the potential for musculoskeletal system disorders (MSDs), although it is not yet in the high-risk category. The conclusion of this study shows that the cabin design has met most of the ergonomic principles, but improvements are still needed to improve driver comfort and safety. Further researchers are advised to conduct a more comprehensive ergonomic analysis by considering anthropometric data from various user body sizes so that the vehicle design can be used optimally by users with various body postures.

Abstract

Pengelasan Shielded Metal Arc Welding (SMAW) banyak digunakan pada bidang manufaktur dan konstruksi, namun kualitas sambungan las dipengaruhi oleh proses pendinginan setelah pengelasan. Penelitian ini bertujuan menganalisis pengaruh variasi media pendingin terhadap kekuatan tarik dan tekan hasil pengelasan baja ST 41. Metode eksperimen dilakukan menggunakan tiga media pendingin, yaitu air es, coolant (air radiator), dan air kelapa, dengan elektroda E6013, arus 110 A, posisi 1G, dan kampuh V 60°. Hasil pengujian menunjukkan bahwa coolant menghasilkan sifat mekanik terbaik dengan kekuatan tarik maksimum 83,481 MPa dan kekuatan tekan 56,722 MPa, dibandingkan air es dan air kelapa. Oleh karena itu, coolant direkomendasikan sebagai media pendingin paling efektif untuk meningkatkan kualitas sambungan las baja ST 41.
