Abstract

Masalah emisi gas buang akan terus berlangsung selama manusia menggunakan bahan bakar fosil. Emisi gas buang dapat diturunkan dengan menggunakan katalis yang terbuat dari berbagai macam material, seperti aluminium, tembaga, seng, dan lainnya. Sehingga penelitian ini dilakukan untuk mengetahui pengaruh penggunaan jenis matrial katalis alumunium dan seng terhadap emisi gas buang HC dan CO. Metode yang digunakan dalam penelitian ini dengan menguji Katalitik converter menggunakan uji eksperimental menggunakan alat uji emisi dan dyno test (uji performa mesin). Dari penelitian diketahui bahwa kadar CO dan HC  terendah pada penggunaan katalis alumunium 2 saringan dengan torsi sebesar 5.69 dan power sebesar 3,9 hp. Menurunnya emisi gas buang karena katalis alumunium dan seng terbukti efektif menurukan kadar CO dan HC. The problem of exhaust emissions will continue as long as humans use fossil fuels. Exhaust gas emissions can be reduced by using catalysts made from various materials, such as aluminum, copper, zinc, and others. So this research was carried out to determine the effect of using aluminum and zinc catalyst materials on HC and Co exhaust emissions. The method used in this research is to test the catalytic converter using experimental tests using emission test equipment and dyno tests (engine performance tests). From the research, it is known that the lowest CO and HC levels are when using  2 filter aluminum catalyst with a torque of 5.69 and a power of 3.9 hp. Reduced exhaust emissions due to aluminum and zinc catalysts proven to be effective in reducing CO and HC levels.

Abstract

Kegagalan material berakibat komponen otomotif bisa menjadi patah, selain itu dapat berakibat chassis suatu kendaraan menjadi megalami lendutan (defleksi).  Faktor yang mempengaruhi kegagalan adalah beban pada suatu komponen kendaraan. Tujuan dari penelitian ini adalah untuk menganalisa tegangan dan defleksi pada engine stand sepeda motor akibat pembebanan. Engine stand menggunakan variasi ketinggian 40 cm, 45 cm dan 50 cm dengan bantuan software Autodesk Inventor Professional 2019. Hasil penelitian menunjukkan ketinggian 40 cm adalah ukuran ketinggian yang paling baik, karena tegangan normal (Smax), tegangan geser Tx, dan defleksinya minimum, walaupun pada nilai tegangan shear stress Ty nya nilainya lebih tinggi dari ukuran lainnya, tetapi nilainya sangat kecil dibandingkan Tegangan yieldnya (0,6 MPa < 207 MPa ). Hal ini berdampak positif pada rangka engine stand karena tidak terjadi deformasi plastis (rangka tidak akan patah). Material failure can cause automotive components to break, besides that it can cause a vehicle's chassis to experience deflection (deflection). Factors that affect failure is the load on a vehicle component . The purpose of this research is to analyze the stress and deflection on the motorcycle engine stand due to loading. The engine stand uses height variations of 40 cm, 45 cm and 50 cm with the help of Autodesk Inventor Professional 2019 software. The results showed that a height of 40 cm is the best measure of height, because the normal stress (Smax), shear stress Tx, and deflection are minimum, even though the shear stress value Ty is higher than the other sizes, the value is very small compared to the yield stress. (0.6 MPa < 207 MPa ). This has a positive impact on the engine stand frame because plastic deformation does not occur (the frame will not break).

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi profil rangka, yaitu besi kotak, besi siku, dan besi U, terhadap respons mekanik rangka alat manual roll bending menggunakan simulasi numerik. Parameter yang dianalisis meliputi tegangan normal, displacement, serta tegangan geser arah Tx dan Ty. Hasil simulasi menunjukkan bahwa profil besi siku menghasilkan nilai tegangan normal, tegangan geser, dan displacement tertinggi, yang mengindikasikan kekakuan struktural paling rendah dan potensi deformasi terbesar. Profil besi kotak menunjukkan kinerja struktural paling stabil dengan nilai tegangan dan displacement yang relatif rendah, sedangkan profil besi U menghasilkan tegangan rendah namun berpotensi mengalami ketidakstabilan akibat penampang terbuka. Berdasarkan hasil tersebut, dapat disimpulkan bahwa profil besi kotak merupakan pilihan paling sesuai untuk rangka alat manual roll bending karena mampu memberikan kekakuan tinggi, distribusi tegangan yang lebih merata, serta deformasi minimum, sehingga mendukung kestabilan dan presisi proses pembengkokan. This study aims to analyze the effect of different frame profiles—square hollow section, angle section, and U-channel—on the mechanical response of a manual roll bending machine frame using numerical simulation. The evaluated parameters include normal stress, displacement, and shear stresses in the Tx and Ty directions. The simulation results indicate that the angle section exhibits the highest normal stress, shear stress, and displacement, reflecting the lowest structural stiffness and the greatest deformation risk. The square hollow section demonstrates the most stable structural performance, characterized by lower stress levels and minimal displacement. Meanwhile, the U-channel shows relatively low stress values but presents potential instability due to its open cross-sectional geometry. Based on these findings, it can be concluded that the square hollow section is the most suitable profile for the main frame of a manual roll bending machine, as it provides higher stiffness, more uniform stress distribution, and minimal deformation, thereby ensuring structural stability and bending precision.
