The superstructure is the main load-bearing construction on the bus body, which introduces a concept of spaceframe structure with the assembly of thin columns structures to achieve lightweight constructions. The lightweight superstructures are designed for electric-based vehicles. The concept of crashworthiness is introduced to maintain the safety of the lightweight superstructures. The criteria for crashworthiness are developed by using international safety regulation. The multi-cell platform is proposed for designing a crash box system to improve the crashworthiness and energy absorption performance of electric vehicles. The multi-cell platform can increase the energy absorption of the crash box. There are several multi-cell configurations being studied, such as cruciform shape, H-shaped, T-shaped, and Y-shaped. The multi-cell columns are subjected to quasi-static and low-speed axial loading. The simulation results show that the multi-cell configurations have different effects on energy absorption capability. Increasing the number of cells and intersection can result in higher energy absorption but detrimental due to peak force. It is found that the optimum crash box system is the H configuration cross-section.

Due to its excellent properties, such as superior electrical conductivity and large surface area, graphene has been extensively studied for its application as anode material for lithium battery application. Graphene fabrication via the electrochemical exfoliation route is promising due to the low-cost and straightforward process. Herein, we added a pretreatment of graphite sheet raw material using the immersion process in H2SO4/H2O2 mixture to pre-intercalate graphite before the exfoliation process. Pre-treatment time in the constant H2SO4/H2O2 volume ratio was optimized to obtain the best electrical conductivity and charge transfer resistance. On the prepared samples, the optimum period is 3 minutes, which generates the electrical conductivity of 3298 S m-1. The smallest charge transfer resistance yielded is 55.90 Ohm. Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) Spectroscopy were utilized for characterizing the morphology and elemental composition of samples.

Electrified vehicles (EV) entry to the Indonesian automotive market at the moment is relatively new, with market penetration being modest at best. This study discusses two major socioeconomic aspects of EVs in their early ventures in the country. First, we examine the feasibility and the impact of accelerating the development of electric cars in Indonesia in economic, environmental, and fiscal aspects. Second, we use primary data analysis by conducting users and prospective car users in the Greater Jakarta area to elicit the consumers’ preferences for electric cars. In this analysis, we specifically estimate the necessary price incentives for each of the EV types, i.e., Hybrid Electric Vehicles (HEV), Plug-in Electric Vehicles (PHEV), and Battery Electric Vehicle (BEV), to gain certain market exposure in the country. We also utilize simulation method in estimating the impacts of various scenarios of policies in accelerating the use of EV vehicles on the automotive industry market and the automotive component industry, as well as government (fiscal), environmental (CO2 emission reduction) and macroeconomic revenues. Our findings suggest that considerable amount of price and non-price incentives is needed to encourage Indonesian consumers to consider EVs compared to ICE. On the environmental and fiscal perspective, we find PHEV serve as the better vehicle to be introduced into the country’s automotive landscape, with a prudent mixture of the three aforementioned EV being also a viable option.

This article delivers the application of magnetorheological elastomers (MREs) as a variable stiffness of surround in a loudspeaker. Firstly, the existing surround was replaced by a set of variable stiffness absorber featuring an MREs. In the preliminary stage, the magnetic circuit absorber was evaluated through simulation work. Then, the simulation using the finite element method magnetic (FEMM) was conducted to predict the performance of MREs. The applied currents were varied from 0 to 1.5 A with an interval of 0.25 A. Later, the average magnetic flux density obtained from the simulation was used for estimating shear storage modulus and shear loss modulus which taken from actual experimental data. The stiffness obtained by processing shear storage modulus and shear loss modulus with an analytical calculation method. Therefore, the performance of MREs could be evaluated. The suspension system MREs which have investigated have good performance, i.e., has a wide range of stiffness.
