Abstract

Fiber metal laminates or commonly known as fiber metal laminates (FML) are composite structures made by combining 2 layers of material as the outer layer with the core material. The outer layer of this composite is called the laminate. Generally, laminated composites are produced by joining techniques under solid-state conditions, such as diffusion bonding, extrusion, friction-stir welding, and roller welding. In this study, glass fiber composites with aluminum lamination were made using the vacuum assisted resin infusion (VARI) method, using epoxy resin. The surface treatment of the aluminum laminate was carried out with the direction of roughing at certain angles and variations of the surface roughening of the laminate to test the mechanical bonding between the composite and the laminate. Mechanical bonding testing using three-point bending test method (three-point bending) and buckling test. The expected result is that by surface treatment on aluminum laminate, the best mechanical bonding to composites with glass fiber is obtained. The TKT to be achieved from this research is TKT level 3, which is an analytical study that supports the prediction of the performance of the effect of the bonding surface treatment on the mechanical properties of glass fiber composites with aluminum lamination.

Abstract

The inconsistency of the wind flow considered as one of the factors which tend to decrease the performance of the wind turbine. This paper proposes a further analysis of the initial rotation characteristic of a hybrid Savonius - Darrieus wind turbine. The addition of the Darrieus blade intends to increase the aerodynamic stability of the overlapping Savonius turbine. This study implements 2D CFD transient analysis using the 6DOF methods in 00, 300, 600, and 900 Darrieus blade position along with 2 m/s, 4 m/s, and 6 m/s wind speed variations. The results of the aerodynamic analysis show that the location of the Darrieus 300 turbine provides the greatest initial repulsion, especially when the turbine rotation is above 900, the position of the Darrieus blade can provide additional impulse force when the Savonius turbine tends to be passive. This effect occurs more significant at higher wind speeds. Savonius with 3-blade modification has a more stable level of force distribution than the 2-blade modification, although the value is smaller. This shows that the 3-blade Savonius provide a higher stability of angular velocity development.

Abstract

This research used the Peltier element as a car cabin cooler. This research aimed to compare the results of the lowest temperature produced by the Peltier element on the hot side. The design of this monitoring tool consists of LM35 as a temperature sensor and an electric velocity sensor to measure the velocity of the cooling fluid. Arduino Uno Microcontroller to control the system before being displayed to the LCD. The type of research used in this research is experimental research. In this study, variations in fluid flow velocity and type of cooling fluid were carried out. The fluid used is a mixture of water and water coolant with a ratio of 50%:50%. The results showed that the circulation of fluid cooling influences the temperature on the hot side of the Peltier. In cooling using water fluid, when the water pump rotates 4.5 liters/second, the temperature on the hot side of the Peltier is 36ᵒC. At the time of rotation of 13 liters/second, the temperature on the hot side of the Peltier is 32ᵒC. The difference between cooling using water fluid, water coolant, or a mixture of water and water coolant greatly affects the temperature produced on the cold side of the Peltier. In cooling using water, the lowest temperature produced reaches 8ᵒC. When the cooling using a fluid coolant, the lowest temperature reaches 6ᵒC. While cooling using a mixture of water and coolant, the lowest temperature reaches 3ᵒC. So it can be concluded that cooling using a mixture of water and water coolant is very effective compared to other fluid coolers.

Abstract

Due to its rust resistance properties, the use of stainless steels, especially SUS304 for industrial equipment is increasing. The manufacturing process that is often used is GMAW welding. One of the disadvantages of SUS304 is the occurrence of distortion and sensitization when welded. In this study, the effect of temperature variations of Static Thermal Tensioning on angle distortion and microstructure behavior due to GMAW welding of SUS 304 T-joint plates was studied. Heating by electric heater is given to both parts of the base metal plate SUS 304 5mm thick with temperature variations of 200 oC, 250 oC and 300 oC. Cooling water with a temperature of 24 oC is provided on the back side of the welded track. Welding using filler ER 304 with a diameter of 0.8 mm with welding parameters such as welding current, voltage, gas flow and travel speed controlled at 75 A, 22 V, 10 l/min and 8 mm/s, respectively. Angular distortion of welding results for each treatment temperature variation was measured using a bevel protractor, and perform metallographic test to knowing the microstructural behavior. The results of the measurement of the average angular distortion of three repetitions show that at a temperature of 250 C static thermal tensioning produces the smallest angular distortion of 3ᵒ70', compared to other temperature variations which produce angular distortion 4o45’ at 200 oC and 3o86' at temperature 300 oC. The findings of the largest Cr (carbide) deposits due to sensitization were found at a temperature of 300 oC at 16,49% and the lowest at a temperature of 200 oC at 7,05%

Abstract

Stainless steel has good mechanical properties compared to other materials for strength and hardness, usually it will increase in hardness after hardening or forging. The purpose of this study was to obtain information about: The value of hardness and tensile strength of martensitic stainless steel forging with various deformations and cooling. The research method used is an experimental method, namely by forging on martensitic stainless steel with variations in deformation and cooling rate. Variations of forging deformation used are 25%, 50%, and 75%. The cooling media used are water, oil and air. The results of forgings with various cooling media were tested for tensile strength and tested for hardness using the Rockwell C (HRC) method. It was found that the higher the value of forging deformation, the higher the value of strength and hardness of martensitic stainless steel. This is because more and more martensite structures are recrystallized. In addition, it was also found that water and air cooling media gave an increase in the hardness of martensitic stainless steels. This is influenced by the cooling rate, where the higher the cooling rate, the more martensite structures formed, thus increasing the hardness value. The increase in hardness value is proportional to the increase in yield strength and tensile strength.

Abstract

One of the biggest problems in the metal welding process, especially for stainless steel, is the occurrence of large distortions. To reduce distortion during the welding process, it is recommended to provide secondary thermal like Static Thermal Tensioning. However, the provision of secondary thermal is allegedly able to decrease residual stress but reduce the corrosion resistance of stainless steel . In this study, variations in temperature of static thermal tensioning were applied during the GMAW process of SUS 304 plate. Furthermore, the results of the welding were made test specimens to determine the residual stress and corrosion rate of each temperature variation. The measurement of the residual stress using slitting method and measurements of the corrosion rate was carried out with the Autolab PGSTAT 204 potentiostat. The measurement results showed that residual stress of the welding results decrease along with the increase in the temperature of the Static Thermal Tensioning treatment where the treatment temperature of 200 ºC have highest residual stress at 113.79 MPa, followed by the treatment temperature of 250 ºC with 105.67 MPa value, and the lowest residual stress at temperature of 300 ºC with 77.82 MPa value. But, the corrosion rate value at the opposite way where the treatment temperature of 200 ºC produces the lowest corrosion rate, which is 0.70 mm/year, followed by the treatment temperature of 250 ºC of 0.99 mm/year and at a treatment temperature of 300 ºC with a corrosion rate of 1.27mm/year.

Abstract

Indonesia merupakan negara muslim terbesar di dunia, dengan jumlah 264 juta penduduk yang tersebar di berbagai pulau. Dengan mayoritas penduduk Indonesia yang beragama muslim maka jumlah tempat peribadatan atau masjid dan mushola jumlahnya sebanding dengan penduduknya. Saat ini terdapat sekitar 250 ribu masjid dan 550 ribu mushola. Namun dari jumlah tersebut tercatat ribuan masjid masih mempunyai peralatan dan penataan sistem tata suara yang buruk. Mushola Al-Khoir yang terletak di Desa Tegalweru, Kecamatan Dau, Kabupaten Malang memiliki system tata suara yang kurang baik, padahal system tersebut harus rutin digunakan untuk kegiatan Mushola Al-Khoir sehari-hari, seperti mengumandangkan adzan, memberikan pengumuman terkait dengan kegiatan sosial, pengajian, dan sebagainya. Pada pengabdian ini diusulkan pelatihan instalasi dan penataan sistem tata suara di Mushola Al-Khoir, Desa Tegalweru, Kecamatan Dau, Kabupaten Malang. Diharapkan dengan adanya pelatihan dan penataan sistem tata suara ini kualitas suara yang dihasilkan semakin bagus sehingga membuat nyaman masyarakat yang ingin beribadah. Selain itu, dengan adanya pelatihan ini diharapkan ketika system tata suara rusak, pengurus mushola dapat memperbaikinya sendiri.

Abstract

Fiber-reinforced composites can be classified into two parts, namely short fiber composites and long fiber composites. Long fibers are stronger than short fibers. Long fiber (continuous fiber) is more efficient in laying than short fiber but short fiber is easier to lay than long fiber. Fiber length affects the processability of the fiber composite. Judging from the theory, long fibers can continue the load and stress from the stress point to the other fiber. In this study, the volume of chopped glass fiber composite with random matrix direction was varied with respect to polyester resin. Making forged fiberglass composites with the press mold method to minimize the occurrence of air bubbles during the composite molding process. Testing the mechanical properties of the forged fiberglass composite using the three-point bending and tensile testing methods. The expected result is the variation of the volume fraction of random chopped glass fiber to polyester resin. The TKT to be achieved from this research is TKT level 3, which is an analytical study that supports the prediction of the performance of the effect of the volume fraction between glass fiber and resin on the mechanical properties of the tensile and bending strength of forged glass fiber composites

Abstract

At this time the power plant still uses a lot of coal fuel, so it is necessary to look for alternative energy, one of which is wind energy. Wind turbines are devices that can convert kinetic energy in the wind into mechanical energy which is then converted into electrical energy through a generator. The analysis method in this research uses Computational Fluid Dynamics (CFD), Qblade, and experimental validation testing using a wind tunnel. The simulated airfoil types consist of 3 types, namely, NACA 4412, NACA 4415, and FX-60 100 (126). The simulation results show that, the most optimal airfoil is NACA 4412 with an angle of attack of 25° and a wind speed of 8 m/s can produce a torque of 3.55503 Nm, a pressure of 45 Pa, a tangential velocity of 55.495 m/s, and a rotational speed of 529. 94 rpm, while the smallest simulation results are on the FX-60 100 (126) airfoil with an angle of attack of 15° and the same wind speed of 8m/s can produce a torque of 1.60390 Nm, a pressure of 40 Pa, a tangential velocity of 9.06592 m/s, and a rotational speed of 108.2164 rpm. The results of experimental testing of wind turbines where the wind turbine used uses the geometry of NACA 4412 show that an angle of attack of 25 ° and a wind speed of 8m / s produces a large electrical power and rpm with a value of 7.98 Watt and 482.2 rpm respectively
