The research problem in this study is difficulty on observing the electronic properties of ZnO materials to fabricate the high performance transistor design with non-toxic semiconductor materials. Even though the wide band gap materials of Group III and V possess high performance properties for fabricating the power electronics devices, the harmful impacts could not be reduced. The research solution for the problem statement in this study is emphasized on the non-toxic materials of Group II and VI-based high performance power electronics devices fabrication. The experimental studies of the device fabrication were conducted by Pulse Laser Deposition (PLD) process in standard laboratory. The step-by-step procedures for MSFET device fabrication were discussed and the confirmation of developed device fabrication was completed. The approaches on all measurement were completed based on band diagram condition, quantum interference on metal-semiconductor materials, and current-voltage characteristics. The step by step measurement for fabricated device for the proposed structure could be confirmed by standard measurement techniques. The proposed design has been validated for the utilization of high performance applications. The physical properties and physical characteristics for measurement results were confirmed by the theoretical analyses. The numerical analyses have been completed with the help of MATLAB. All results have been proved by recent research works.","PeriodicalId":434097,"journal":{"name":"Journal of Engineering Researcher and Lecturer","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139270763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":434097,"journal":{"name":"Journal of Engineering Researcher and Lecturer","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134228437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":434097,"journal":{"name":"Journal of Engineering Researcher and Lecturer","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131583337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its role is quite significant, as it includes a take-up system to adjust the tension and slackness of the chain on the sprocket against the Lamella. Based on observations in a mining industry, it was found that tail-shaft damage frequently occurs, likely due to the excess load carried by the conveyor. Therefore, researchers were interested in investigating the maximum capacity of the tail-shaft. The research was conducted using the Finite Element Analysis method with Solidworks Research License. The material used for the tail-shaft is DIN 1.0038. Torque variations tested on the tail-shaft were from 42,000 N.m to 58,000 N.m. Based on the simulation results, the maximum torque that the tail-shaft can withstand is 54,000 N.m with a safety factor value greater than 1, whereas when given a torque of 58,000 N.m, the safety factor value is less than 1. The tail-shaft experiences a maximum stress that exceeds the yield strength of DIN 1.0038 material, which can cause damage to the material. The initial damage appears at the end of the shaft due to the use of chamfer. This is known based on the results of simulations that have been conducted.","PeriodicalId":434097,"journal":{"name":"Journal of Engineering Researcher and Lecturer","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133670554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to develop an Augmented Reality learning media application for the Engineering Mechanics course, which is considered challenging by some students. Engineering mechanics, a discipline that analyzes structural analysis in compensating for the loads that work on a particular machine in scalar quantities, motion forces, vectors, and moments that require physical structural forms to analyze them, is considered challenging by some students. The Augmented Reality application was created using the prototyping method, which consists of three steps: 1) listening to the customer, 2) building/ revising mock-up, and 3) customer test-drivers mock-up. The AR-based learning media application includes usage instructions, developer info, learning videos, 3D AR object animation simulations, and exercise and discussion menus, which were tested as expected. The results of the black box testing indicate that the Augmented Reality-based engineering mechanics learning media application ran successfully as expected. However, users suggested improving the navigation speed by streamlining page transitions. The application provides an accessible solution for students as an alternative to traditional distance education, offering anytime, anywhere access to learning materials with longer duration.","PeriodicalId":434097,"journal":{"name":"Journal of Engineering Researcher and Lecturer","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114660718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, learning in educational institutions is not supported by facilities that match those in the industry, but only simulation tools. Additionally, the media used in educational institutions is not as sophisticated as that used in the industry. This study is a literature review on Work-based Learning (WBL) and the formulation of WBL concepts suitable for vocational education in the engineering field. The results of the literature review showed that the implementation of WBL in various developing and advanced countries is very effective in developing students' competencies. Educational institutions and industries work together to improve the quality of learning to produce job-ready graduates. Industries benefit from the availability of competent and professional workforce who can develop their business for global competition. There are three WBL model concepts that can be applied to vocational education in the engineering field, including integrated student work, teaching factory, and industrial internship. The formation of student competencies can be carried out through a structured program, where students will gain experience and opportunities to gradually sharpen their competencies.","PeriodicalId":434097,"journal":{"name":"Journal of Engineering Researcher and Lecturer","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114932738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
