<![CDATA[The development of composite materials currently not only with synthetic reinforcing materials but also with natural fiber reinforcing materials, because natural fibers have diverse characteristics. In this research, looking at the characteristics of Oil Palm Empety Fruit Bunch (OPEFB) fiber which has a high cellulose and hemicellulose content, which is generally used for soundproofing materials. So a composite research will be made from the main material of OPEFB fiber with polyester resin as the matrix. The purpose of this research is to determine the sound absorption value of the composition of the mixture of OPEFB fiber and resin. The method used is the hand lay-up method combined with the Taguchi Method on the L4(23) orthogonal matrix design used as a reference for the sound absorbing composite manufacturing process. The L4(23) orthogonal matrix design is used because there are three process parameters that have two levels. Repetition is repeated three times. The process parameters are the volume fraction of OPEFB fiber and resin, the length of fiber soaking with NaOH, and the thickness of the composite. The research results from three repetitions obtained the highest value in sample I with a mean value = 77.93 dB at a frequency of 2000 Hz, and the lowest value in sample III with a mean value = 32.97 dB at a frequency of 125 Hz.]]>

<![CDATA[Friction welding is one of the metal joining methods, by utilizing the heat generated from the physical contact of two metals in the form of friction that occurs continuously on the two metals to produce a welding joint. This research aims to find out what phenomena occur in the connection between AISI 1040 and Brass. The materials used are AISI 1040 solid cylinder with a diameter of 16 mm and brass solid cylinder with a diameter of 16 mm. This research uses experimental method. The friction time used is 6 minutes, 7 minutes, and 8 minutes with a variation of pressing distance of 3 mm, 4 mm, 5 mm with a rotating speed of 1000 rpm. The free heat process of 200 ℃ was carried out on AISI 1040 before the welding process. From the time variation and pressing distance variation that has been carried out in this study, the results obtained from the two materials do not occur. There are several phenomena seen after the welding process such as the occurrence of plastic deformation in brass and the formation of a brass thermoplastic layer attached to the surface of AISI 1040, in the time variation of 6 minutes and 7 minutes the brass thermoplastic attached to AISI 1040 is small and thin, while in the time variation of 8 minutes the brass thermoplastic layer attached to AISI is quite a lot and thick but no connection has occurred. This friction welding method is likely to connect the AISI 1040 material with brass by increasing the friction time performed.]]>

<![CDATA[A pick-up car is a car that has a tub at the back that is useful for lifting goods. The body or tailgate of the car is designed to use iron plates so that the car is stronger and more durable. Vehicles are greatly affected by noise and vibration levels. The resulting vibrations come from the engine, the floor of the vehicle cabin, and the road that has an effect on the vehicle. Vibration can be reduced by increasing the stiffness. Stiffness can be increased by making grooves in the panels. The purpose of this research is to increase the natural frequency and stiffness of the plates by forming grooves in the plates. The materials used in this study were galvanic plates with plate thicknesses of 0.6 mm and 0.8 mm. The research method is demonstrated as follows: determine the dimensions of the plate, the process of making grooves, measure and analyze the natural frequency and stiffness. The length and width of the plates are 580 mm and 600 mm. The groove used is in the form of a trapezoid by means of a rolling process. The results of the grooved plate experienced a 3-fold increase in frequency compared to the flat plate.]]>

<![CDATA[Public interest in pick-up cars as a means of transportation for transporting goods has continued to increase lately because they are considered more flexible for transporting raw materials, workshop products and agricultural products and are capable of being operated on urban and rural roads that have different road roughness, as well as in very high traffic conditions. Plate panels that must be used in pick-up vehicles need to be designed as thin as possible but have high stiffness and natural frequency so that they are more efficient in fuel use and able to withstand vibrations that occur during driving. This study aims to determine the natural frequency that occurs in the plate panel profile for vehicle bodies resulting from the cold rolling process. The galvanized steel plates used are 0.6 and 0.8 mm thick. The natural frequency test method is used with free boundary conditions, where the conditioning plate is suspended by a rope. The natural frequency test tool used is the vibroport 80 at an existential pressure of 10 grams, with the hammer hitting the centre of the panel and the sensors being positioned at 0 and 90 degrees. Based on the test results that have been carried out, the panel specimen with a thickness of 0.8 mm obtained the highest natural frequency value of 922.5 Hz, while for a plate thickness of 0.6 mm, the highest value was only 816.25 Hz. However, the two groups of specimens with plate panel thicknesses of 0.6 and 0.8 mm because of rolling experienced an average increase in natural frequency, reaching 2.3 – 2.5 times when compared to the flat plates without the rolling process. The conclusion is that as the natural frequency value increases, the plate panel stiffness also increases.]]>

<![CDATA[Synthetic fiber composite materials such as glass fiber, aramid and carbon fiber have good mechanical properties, but cause environmental pollution because they cannot be recycled. Because of this, many researchers are making composites with natural fibers. The advantages of natural fibers include: lower price, easy processing, reduced CO2 emissions, and specific strength meets application requirements. Composites are materials composed of a mixture of more than two different main elements. Composites have the advantages of light weight, higher strength, and corrosion resistance. This study applies the full factorial design method, which will look at the effect of the composite ratio (volume fraction and between fiber layers) on tensile strength. The purpose of this research is to determine the effect of variations in volume fraction and fiber layers of kepok banana stems on tensile strength. So that it can be used as an alternative material for making SNI helmets. This study used variations in volume fractions of 10%, 15%, and 20% and variations in fiber layers of 3, 4, and 5 kepok banana stems. Liquid smoke soaking time was 60 minutes. The average value of the maximum tensile test in the 4th layer, 10% volume fraction of fiber with a value of 42.76 Mpa and the minimum average value in the 3rd layer using 10% volume fraction of fiber with a value of 30.06 Mpa.]]>
