Sepeda gunung banyak diminati karena desainnya yang menarik dan kegunaannya yang cocok untuk medan terjal dan curam. Rangka sepeda gunung harus sangat kuat untuk menanggung beban di berbagai kondisi medan. Penelitian ini menggunakan perangkat lunak Autodesk Inventor untuk merancang rangka sepeda dengan mempertimbangkan variasi beban yang sesuai dengan rata-rata berat manusia. Hasil analisis menunjukkan tegangan Von Mises maksimum 102,9 MPa, perpindahan maksimum 0,02816 mm, dan faktor keamanan minimal 2,43. Faktor keamanan pada titik acuan dengan tegangan tertinggi jauh melebihi batas desain yang diizinkan sehingga desain ini dianggap aman.

Strong current in welding is something that has always been a problem in the welding process. High currents can cause penetration of the welded material, whereas low currents can cause shallow penetration. The purpose of the study was to determine the effect of current on the tensile and bending strength of V seam welded joints using SMAW welding with E6013 electrodes on low carbon steel welding. The research method used is to make a seam on a steel plate with an angle of 60 degrees and then weld it with a different current. The current used is 70, 90, 110 amperes with an electrode diameter of 2.6 mm. The samples that have been welded are then formed into tensile and bending test specimens. The results showed that the highest average tensile stress was 518.310 MPa at a welding current of 110 amperes. The highest average tensile strain is 34.00% at a welding current of 70 amperes. The highest average elastic modulus is 0.01864 GPa at a welding current of 110 amperes. For bending testing at 70 amperes, the fb1 specimen has cracks in the weld metal area with a crack length of 1.00 mm and the fb2 specimen has 0.50 mm cracks, while the 90 amperes fb1 specimen has 1.00 mm cracks, and fb2 specimens have 0.50mm crack. Current 110 amperes fb1 specimen has a crack of 4.70 mm, and fb2 specimen has a crack of 3.00 mm. From the results of the study, a good welding current for a plate with a thickness of 7.5 mm with an E6013 electrode with a diameter of 2.6 mm is at a current of 90 amperes.

Waste is a residual production material that contains substances capable of causing pollution and health disturbances. One of the waste types frequently encountered is cigarette filter waste and wood powder waste, both of which are managed minimally. This research aims to determine the influence of the composition of a mixture of cigarette filter waste and wood powder waste on sound absorption in composite materials. The method involved preparing the necessary tools and materials, then creating composites with fractions (65%, 20%: 10%, 15%), (60%, 20%: 13%, 7%), and (55%, 20%: 15%, 10%). Subsequently, sound absorption testing was conducted using the direct method following ISO 11654 standards. Results from the sound absorption testing at a frequency of 500 Hz showed the highest sound intensity value in the fraction (65%, 20%: 10%, 15%) at 104,833 dBa and the lowest in the fraction (55%, 20%: 15%, 10%) at 93,333 dBa. The highest sound absorption coefficient value was found in the fraction (55%, 20%: 15%, 10%) at 0,202, while the lowest was in the fraction (65%, 20%: 10%, 15%) at 0,104. As the volume of acoustic material from cigarette filter waste and wood powder waste increased, the sound absorption coefficient also increased. The best sound absorption coefficient value was observed in the fraction (55%, 20%: 15%, 10%) at 0,202

The machining process is a manufacturing process where the main process is removing or removing some of the material from a basic material which can be in the form of a shaft so that it meets the desired shape and quality. The purpose of this study was to determine the effect of the rotational speed of the lathe spindle on the value of Unit Horse Power (UHP) in the low carbon steel turning process. The study used carbon steel material in the form of a cylinder with an initial diameter of 40 mm and a length of 150 mm. The cylindrical workpiece is turned with a depth of 1 mm at various speeds, namely 95 rpm, 130 rpm and 180 rpm. The results showed that the rotational speed of the lathe spindle affects the value of the unit horse power (UHP). The higher the spindle rotation of the lathe, the greater the UHP obtained, where the highest UHP occurs at 180 rpm with a UHP value of 0.00030 and the lowest UHP. found in round 130 with a UHP value of 0.00016. High rotation causes a large force so that the vibration of the lathe tool is even greater.Keywords: Lathe process, carbon steel, spindle rotation.
