Abstract

Goen's distance formula effectively calculates the distance from acceleration, which has a pattern as a symmetric function of time changes. In Goen's distance formula, where the acceleration function against time has a symmetric pattern, it can be solved simply by performing a total integral and multiplying it by half of the total time. Symmetric acceleration functions can be constructed by combining certain functions with their reflections. In this study, the method of proving Goen's distance formula is carried out mathematically using single and double-level average integrals of symmetric functions. The advantage of Goen's distance formula compared to the conventional distance formula is that in finding the distance traveled by an object moving with a symmetric acceleration function, it will be more effective because it is sufficient to perform an integral once compared to having to do two integrals as done in the conventional method.

Abstract

PT. SMT is a company that manufactures and distributes motorbikes. One of the main products assembled by PT. SMT is a 160 cc motorcycle engine. To improve the quality of the motorbike engine assembly process at PT. SMT, quality management based on the Seven Tools method has been performed. The check sheet analysis based on the production data from the January-July 2023 period shows that the most frequent quality issues in the engine assembly process are dirt on the cylinder inlet valve (64, 2%), followed by rust on the cylinder head (26.1%) and dirt on the gasket cover components for the cylinder head (9.8%). Root cause analysis using the Fishbone diagram finds that work environment factors including dirty workstations, equipment and components, as well as human factors are the main causes of product defects. From this analysis, the recommended improvements include implementing routine cleaning procedures for the work environment, equipment, and components, as well as providing additional training to improve operator competency and foster a better work culture.

Abstract

This study was focus on converting internal combustion engine (ICE) vehicles to electric vehicles (EVs) using GT-Suite simulations, focusing on the integration of electric drive system. With increasing global CO2 emissions, many nations aim to achieve carbon neutrality, making the shift to electrification crucial. While new battery electric vehicles (BEVs) produce significantly lower greenhouse gas (GHG) emissions, the high costs associated with new EV production remain a barrier to widespread adoption. Thus, converting existing ICE vehicles into EVs emerges as a more cost-effective and environmentally beneficial strategy. Using Toyota Avanza as a base model, replacing the ICE with a Synchronous AC motor and a LiFePO4 battery pack. Simulation results indicate competitive performance, with a 0-100 km/h acceleration time of 14 seconds, a top speed of 190 km/h, and an estimated driving range of 310 km. This study demonstrates that ICE-to-EV conversions can accelerate the transition to sustainable transportation.

Abstract

A reliable control system is essential for the operation of a wheeled robot. A castor wheel is a robotic control device that enables the wheeled robot to navigate to various positions and orientations. One implementation method employs a servo motor to adjust the orientation of the castor wheel to a specific driving angle. The mechanism is robust, cost-effective, and simple to produce. This work demonstrates the development of a castor-wheel-based control mechanism utilizing a servo motor and the pure pursuit algorithm to determine the driving angle. The designated wheeled robot employs a BLDC motor as the primary actuator for its two main wheels. An experiment has been performed to assess the proposed control mechanism. The proposed control system achieved a position error of 0.228 m in the Y direction minimally and less than 1 m position error globally. This study presents mechanical, electrical, and software components.

Abstract

Current engineering technology places great emphasis on efficient and energy-saving construction. Nowadays, research and development of engineering materials are more directed at relatively strong, stable and lightweight materials. Polymers and natural fiber reinforced polymer composites are one of those that can meet these needs and are being researched. To achieve optimal results, the research must be supported by appropriate test equipment that can properly characterize the materials being developed. This research aims to design a mechanical and electrical tensile testing device especially for polymers and polymer composites. The research produced a prototype of a tensile testing device that has a maximum load capacity of 20.25 kN. The success of this research is proven by the strength of PMMA, which was tested using this device. The test results showed that PMMA has a tensile strength of about 58.2 and 60.7 MPa. This value is within the range of PMMA strength obtained from the literature.

Abstract

The growing adoption of electric vehicles (EVs) in Southeast Asia, particularly in Indonesia and Malaysia, is driven by policy incentives such as road tax exemptions and relaxed traffic restrictions. This study investigates the feasibility and performance impact of integrating a stock automatic transmission into a converted internal combustion engine (ICE) vehicle, replacing the commonly used single gear or manual transmissions in typical EV conversions. Using GT-Suite simulation software, a detailed model of a converted Toyota Avanza was developed to evaluate key performance metrics including acceleration, top speed, driving range, and energy consumption. Simulation results indicate that integrating an automatic transmission improves acceleration performance, reducing the 0–100 km/h time by 0.7 seconds compared to a single-gear configuration. Although the top speed is mechanically limited by the transmission's maximum input speed, the vehicle achieved a marginally higher top speed (191.3 km/h) and reached it 1.8 seconds faster. During range simulations under the New European Driving Cycle (NEDC) and constant highway driving at 100 km/h, the automatic transmission variant demonstrated a longer driving range—up to 7% farther—while also improving energy consumption from 8.55 km/kWh to 8.77 km/kWh.
