The Journal of Engineering Researcher and Lecturer is dedicated as a forum for researchers and lecturers around the world to report the research results. All papers are peer-reviewed by at least two referees. The scope includes technological and learning innovation in engineering (miscellaneous). Technological innovation must be carried out continuously for a better life. However, its sustainability is inseparable from human resources. Thus, manuscripts on learning innovation are expected to be a reference in decision-making for a policy on engineering education, resulting in superior students in a sustainable manner. Technological innovations are expected to be a learning reference and can be mastered by students for sustainable human resource development.

Abstract

The frame is one of the critical components of a motorcycle. It needs to be robust, strong, and capable of withstanding various loads such as the engine, body, fuel tank, riders, passengers, and more. Apart from serving as a support for riders, passengers, and cargo, the frame also plays a vital role in connecting the front and rear suspension systems and linking the rear with the front wheel. This research aims to determine the strength of two material profiles, namely circular tube and square tube, in a comparison between AISI 1035 steel (SS) and AISI 1020 for the frame of an electric motorcycle. The comparison is analyzed through simulation results obtained using SolidWorks Research License 2021-2022 with the finite element method. The simulation results reveal that the most suitable profile and material for the frame, characterized by strength, durability, and load-bearing capacity, is the circular tube with AISI 1035 steel (SS). The data shows that the maximum stress occurring after applying the specified load remains within the yield strength of the material. Compared to other profiles and materials, this combination exhibits lower maximum stress, making it a superior choice. This study provides valuable insights into designing a motorcycle frame that can withstand various stresses while ensuring rider safety and optimal performance.

Abstract

The swing arm is one of the main components of a motorcycle that functions as a connection between the rear wheel and the frame. Under loading conditions, the joint area between the arm and the bridge experiences significant stress, leading to fractures in that region. This study aims to investigate the effectiveness of installing gussets to reduce the stress that occurs at the joint area between the arm and the bridge in the swing arm of ELGO electric motorcycles. The research was conducted using the static analysis simulation method with Solidworks 2021-2022 Research License software. The loading conditions were simulated based on the actual usage of the electric motorcycle. The simulation results revealed that without the installation of gussets, the joint area between the arm and the bridge in the swing arm experienced stress exceeding the yield strength of the material. This would inevitably lead to the breakage of the swing arm and potentially cause accidents for motorcycle riders. However, after the gussets were installed, the stress at the joint area between the arm and the bridge remained below the yield strength of the material. Based on these findings, it can be concluded that the installation of gussets successfully reduced the stress at the joint area between the arm and the bridge in the swing arm. This research outcome can serve as a reference for the design of swing arms for electric motorcycles.

Abstract

Heatsink is composed of square or circular-shaped base plates connected to fins on one side. Fluid flow within the heatsink typically occurs through natural convection, where colder air flows into the hotter fin region and exits through the fin tips. In this study, we conducted numerical simulations using Solidworks 2021-2022 Research Licence software to investigate three different heatsink models with distinct shapes, aiming to determine the most effective cooling rate. The thermal simulation results revealed that the heatsink design with square fins exhibited lower maximum temperatures, making it recommended for applications utilizing natural convection. Additionally, heat sinks with thinner fins have a larger surface area, accommodating more fins compared to thicker ones, which affects the heat transfer efficiency within the heat sink.

Abstract

The soft skills competencies needed in the industrial revolution 4.0 era on the 21st century are critical thinking, creativity, communication and collaboration or known as 4Cs Skills. This study aims at revealing a teaching activity that can develop and improve the 4Cs skills of vocational education students. This research was a quantitative study using a survey method. The research instrument used a questionnaire of the lecturers' statements about teaching activities carried out by educators to improve or develop the 4Cs skills of vocational education students. The respondents in this study were 403 educators that consisting of 200 educators from Universitas Negeri Padang (Indonesia) and 203 educators from Universiti Tun Hussein on Malaysia (Malaysia). Based on the research findings, it was found that the teaching activity that was most often carried out or appeared with a high percentage in improving students' 4Cs skills was problem solving to improve critical thinking skills, debate to improve communication skills, peer partner learning to improve collaboration skills and finally mind mapping to improve creative skills. Based on the results of this study, lecturers in the implementation of learning need to condition learning activities that can develop students' 4Cs skills, so that the competencies possessed are in accordance with the needs of the developing industry in this 21st century.

Abstract

Stability is an important aspect that was studied in ship design as it relates to the safety of the ship when facing ocean waves. The tourist ship needed to have a good image in order to attract tourists to use its services. Good stability of the tourist ship was crucial in enhancing the image of the ship and attracting tourists to utilize its services. This research aimed to investigate the effect of concave on the U hull to improve ship stability. The study compared the stability test results of two hull designs: U hull with concave and without concave. The stability tests of both ship models were conducted through simulation methods. The simulations were performed under two conditions: when the tourist ship was empty and when it was fully loaded with passengers. The simulation results indicated that the design of the U hull with concave had a positive influence on ship stability, leading to improved stability. The concave design enhanced the ship's ability to return to its original position when encountering waves. Even in the presence of small waves, the tourist ship did not experience instability.
