Compared to other spare parts, the engine plays a crucial role in vehicle operation. The primary purpose of the engine is to generate rotary power through the combustion of the air and fuel mixture contained within it. Therefore, optimal engine performance must be considered for the perfection of motorized vehicles, and external supporting factors that contribute to optimal engine performance must be identified. If this external supporting factor correlates with the used variables, it can be identified as a suppressor variable. A suppressor variable can improve engine performance by increasing the value of the coefficient of determination. The objectives of this study are to determine the type of suppressor variable and whether the suppressor variable can affect the performance of a car engine. According to the findings of this study, tire size (positive net suppression) and digital tuning (negative classical suppression) are suppressor variables that can influence the enhancement of automobile engine performance","PeriodicalId":490621,"journal":{"name":"Jurnal Asiimetrik","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135440925","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}

At the time of inspection, the technician discovered damage to the wheel's surface. This is due to the hardening of the brake block, which damages the wheel's surface. This research was conducted with the purpose of analyzing the causes of damage to the tread surface of the wheels and identifying a suitable replacement for the original brake block, which is no longer manufactured and has been replaced by imitation block brakes. so that further action can be taken to prevent similar occurrences in the future. Using the Vickers hardness test indentation method, the purpose of this study is to examine various heat treatments for determining a material's hardness level. The test results indicate that the VHN value increases with increasing heating temperature. The original specimen produced 99.5 VHN in the first test without heat treatment, while the X block brake produced 26.9 VHN and the Y brake produced 136.0 VHN. The second test with 200°C heat treatment on the original specimen yielded 96.8 VHN, 73.1 VHN from the X block, and 152.9 VHN from the Y block. In addition, the third test with 400°C heat treatment on the original specimen produced 92.4 VHN, 47.8 VHN for the X block brake, and 268.3 VHN for the Y block brake. The Vickers Hardness Test (VHN) hardness value is affected by heat treatment; the higher the heating value, the higher the hardness value of the remolok specimen.","PeriodicalId":490621,"journal":{"name":"Jurnal Asiimetrik","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135441214","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}

With appropriate air quality and thermal comfort, it is easier for students to focus on the learning process. In addition, better air circulation can also benefit to the health of the people inside the building, for instance, according to WHO (World Health Organization), appropriate airflow may reduce the spread of SARS-CoV-2 which lately has caused a COVID-19 pandemic. However, air circulation and distribution have not a concern yet due to existing room condition and advanced technology that is needed, in L 609 classroom and Heat & Mass Transfer Laboratory, in this research. CFD method implementation for this case is used to show existing air circulation condition and necessary recommendations to get better air circulation. CFD simulation is done 3 dimensionally with 44344 nodes tetrahedral mesh on 2 configuration room condition, which are classified based on air input from AC, door gap, and with or without window opening. Based on CFD simulation results, the 2nd configuration with window opening indicate the best configuration with air velocity around 0,8 m/s dan room temperature 295,8 – 302,1 K. With window opening, the air flow condition met the ANSI/ASHRAE 55 and hoped to reduce COVID-19 spreading.","PeriodicalId":490621,"journal":{"name":"Jurnal Asiimetrik","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135440926","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}

The zinc layer on the galvanized steel surface should not be damaged during the material forming process. The zinc layer on the galvanized steel sheet will affect the metal forming process. This study uses an experimental design with four input parameters, namely v-die opening L (mm), punch angle (degree), punch speed (mm/minutes), and bending force (kN). The smallest spring-back was obtained in the 4th test sample: the v-die opening of 35 mm, the punch angle of 40o, the punch speed of 30 mm/minute, and the bending force of 7.50 kN. The minor spring-back degree was 1.67o. Meanwhile, the smallest spring-go obtained in the second sample, namely the v-die opening of 30 mm, the punch angle of 50o, the punch speed of 40 mm/minute, and the bending force of 7.00 kN, the minor spring-go degree of 0.92o was obtained. These results show that the best spring-back degree for SECC/JIS G 3313 material is obtained when the bending process is performed with the v-die bending parameter of 30 mm, punch angle of 50o, punch speed of 40 mm/minute, and bending force of 7.00 kN.","PeriodicalId":490621,"journal":{"name":"Jurnal Asiimetrik","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135440921","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}

The most prevalent form of cerebral palsy is spastic diplegia, which causes walking difficulties. People with cerebral palsy, particularly children, require mobility aids, such as wheelchairs, to perform daily tasks. When designing wheelchairs for children with cerebral palsy, ergonomic evaluation is required to ensure that the resulting wheelchair is safe and will not pose a risk in the future. This paper investigates the use of digital human modeling to evaluate the ergonomics of wheelchairs for children with cerebral palsy. The method is used to collect samples from 5 to 18-year-old children with cerebral palsy. Digital human modeling is used to simulate and evaluate ergonomics using anthropometric data. The results obtained for the wheelchair dimensions are suitable for the 95th percentile value, while the seat length exceeds the popliteal length for the 50th percentile value. The ergonomic evaluation yielded satisfactory results for the lower back analysis parameter, and the comfort evaluation yielded satisfactory results for the 95th percentile value. In contrast, the 5th percentile value indicates knee discomfort in both the right and left knee.","PeriodicalId":490621,"journal":{"name":"Jurnal Asiimetrik","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135440924","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}
