Dwi Handayani — 2024-05-03

The continuous use of fossil energy can have an impact on the energy crisis and environmental pollution Greenhouse Gas (GHG) is a contributing factor to climate change. Electric cars are one of the solutions to these problems. Because electric cars use clean and renewable electrical resources to drive their vehicles, they can reduce dependence on limited fossil fuels. In the use of electric cars that utilize regenerative braking technology, the first stage is to design the portion of mechanical braking on both the front and rear wheels, along with regenerative braking. The goal is to obtain a safe braking portion by following the ideal braking upper limit that has been set, as well as the lower limit set by the ECE braking standard. After obtaining a safe braking portion that is in accordance with actual conditions, the next step is to find the energy generated by the regenerative braking system by simulating it using Matlab-simulink. In this simulation, the regenerative brake efficiency can be obtained by comparing the absorbed energy and the available braking energy. The regenerative brake system in this study is able to absorb 1.7623 kWh of energy with an efficiency of 67.31% at a regenerative braking portion of 0.137 and front mechanical braking of 0.6629 at a road friction coefficient of 0.8.

Gabrielle Halim — 2024-05-15

In the development of the industrial revolution 4.0, in carrying out production at small, medium, and large levels, there has been a fairly large and significant increase. Factors that influence the goal of successful production are not only about investment, capital, suppliers, machines, skills, and distributors but also one that must be observed is the layout planning and placement of factory facilities. PT. Eworx Indonesia is a company engaged in the processing industry, especially manufacturing in the metal processing sector. PT. Eworx Indonesia intends to relocate the production floor in order to increase production productivity. In this study, the proposed layout design on the new production floor was carried out using the SLP, Blocplan, and FLAP methods. The design is done by collecting direct observation data and interviews with the operator on duty. It was found that the initial layout had problems with operator movement that was not optimal and the placement of several machines and facilities that did not pay attention to material flow resulting in a slowdown in production time. Therefore, in order to get the best layout, a comparison is made on the results of the three alternative layouts with the smallest displacement distance comparison so that the production process will run more optimally. The best proposed layout is the systematic layout planning (SLP) method with the smallest material displacement distance of 147.4 meters and material handling costs Rp. 223,958 per day. Flexsim simulations show this layout can increase production output by 15%-34%.
