Abstract

Current leakage in parallel gap single-sided double spot welding tools occurs if the insulation to the mass-body, either from the work table or the drive system, can reduce the current concentration and result in double-sided welding being relatively difficult to carry out or the weld results being poor. Therefore in this research, an experiment was carried out to test the machine how big the effect of leakage current is on the quality of welded joints by comparing the strength of the joint between a system without insulation and a system using insulation using the independent sample t-test statistical method with a confidence level of 95%. The results of the study show that overall the max load for CT 3 to 10 is a mean difference between without and with insulation, although it is not very significant, this is because the shear test data from the group without insulation has quite a high deviation. High deviations also occur in the upper yield data, the strongest conclusion is that providing insulation (or preventing leakage current) provides a more consistent welding result as seen from the results of the shear test data. Only CT 3 has a significant impact on both max load and upper yield.

Abstract

Indramayu is the largest rice barn area in Java, so it contributes waste from the rice production process, but the waste processing process is less productive or there are very few enthusiasts. So there is a very big opportunity by utilizing waste which is more useful, namely by processing it into fish pellets which have a high price value compared to other processing methods. The design of the rice husk grinding machine uses a type 32 disk mill knife and a type 32 fish pellet printer that will print 3 mm pellets with a machine frame dimension of 849 x 597 x 918. The frame of this machine uses 40 x 40 x 1.35 mm hollow iron. The specifications of this fish machine consist of three main components, namely a husk refiner, a pellet dough mixer, and a fish pellet molder driven by a combustion engine with the motor power and speed used, namely a refiner power of 1.82 HP with a speed of 3600 rpm, a mixer power of 1.86 HP with a speed of 771.42 rpm, a molding power of 0.56 HP with a speed of 771.42 rpm. So the total power used for this machine is 5.5 HP or 4.1 kw. So it can be seen that the motor power is 5.5 HP < 7 HP, so a 7 HP drive motor can be used.

Abstract

Separating rice and bran, moving rice to storage, and other processes related to moving grain or rice. In the modern rice milling industry, the process of transferring grain material already uses a pneumatic conveying system; a vacuum blower system for transferring grain is needed when milling grain to become rice. The research method used to obtain the shape of a vacuum blower with strong inlet suction power and outlet thrust is carried out by Computational Fluid Dynamics simulation and testing several types and variations in the number of blades. Simulation of forward curved blade type impellers, backward curved blade, and straight radial blade with variations in the number of 8, 10, and 12 blades. From the impeller simulation, it was obtained that the straight radial blade with 8 blades was the best. The best impeller types were made using the manual method. Measurement results were on the straight radial blade type impeller with 8 blades, with a motor speed of 1,000 rpm; the results of measuring air speed at the inlet were 34.95 m/s and at the outlet 23.08 m/s. In addition, the difference in the results between in simulation and the experiment is due to the fabrication process and air leaks.

Abstract

ASTM A36 is a type of structural metal that can be applied for various purposes such as making gears, bridge structures and ship buildings. After welding, ASTM A36 steel will produce residual stress. Residual stress in the welded metal is caused not balanced temperature distribution. The method for eliminating residual stress is tempering. Tempering is used to reduce residual stresses, increase the ductility and toughness of metals. This research aims to analyze the effect of variations in tempering temperature on the mechanical properties of ASTM A36 steel after SMAW welding using E7016 electrodes. The tensile strength test on the specimen showed the highest increase due to the tempering effect of 537,880 MPa at a temperature of 200°C. This is proven by the reduction in material hardness of 165.07 VHN at a tempering temperature of 200°C when compared to the hardness of the raw material. The growth of ferrite grains in the material structure shows that the ASTM A36 material is increasingly ductile after tempering. The results of research on the effect of variations in tempering temperature on the mechanical properties of ASTM A36 can be used as an alternative way to increase ductility after the welding process

Abstract

Metal-matrix composites (MMCs) offer superior mechanical properties, making them ideal for advanced engineering applications. However, achieving optimal strength and hardness remains a challenge. This study investigated the role of copper (Cu) reinforcement in enhancing the mechanical performance of aluminum-silicon carbide (Al-SiC) composites fabricated via powder metallurgy. Composites were synthesized with 5 wt.% and 10 wt.% Cu and sintered at 500°C, 550°C, and 600°C. The results indicate that increasing Cu content significantly improved hardness and bending strength, with the 80%Al–10%Cu– 10%SiC composition exhibiting the highest hardness (96.86 kg/mm²) and bending strength (29.08 MPa) at 600°C representing a 37.86% and 74.03% increase, respectively, compared to the 5 wt.% Cu composites. Microstructural analysis confirmed uniform Cu and SiC dispersion, improved matrix bonding, and reduced porosity at elevated sintering temperatures. These findings highlight the potential of Cu-reinforced AlSiC composites for high-performance applications, particularly in wearresistant and structural components.
