Abstract

Welding is one of the methods widely used in the joining of metals for structural elements. One of the factors that influence the strength of welded metals is types of welding joints. Suitability of the type of welding joint with geometries of base metals is required to obtain welded metal products with optimum properties. In this study an attempt is made to investigate mechanical properties of welded metals with two different types of joints (single-V and double-V) using the shielded metal arc welding (SMAW) process. Low carbon steel with bevel angle of 60° was used in this study. Welding process was performed using current of 70 A with a constant welding speed. The flexural properties and uniaxial tensile properties are studied by three-point bending test and uniaxial tensile test respectively. Test results show that the tensile strength and the bending strength of single-V specimens is 521.64 N/mm2 and 525.11 N/mm2 respectively. In addition, the tensile strength and the bending strength of double-V specimens is 517.33 N/mm2 and  504.24 N/mm2 respectively

Abstract

Bricks are bricks made from a mixture of hydraulic adhesives added with fine aggregate and water without any other additives and have a cross-sectional area of ​​the holes of more than 25% of the cross-section of the bricks and the contents of the holes of more than 25% of the contents of the bricks. The purpose of this final project is to design a brick making machine using compressor pressure, design the selection of body materials and frames made of U iron, the main driver is the compressor and the wind work system from the compressor is channeled to the modified car tire pressure tube (tiptop tube) and then assembling the components, namely the frame, car tire pressure tubes (tiptop tubes), brick molds and brick dough container. The final design of the design of the brick making tool uses compressor pressure, namely the brick printing tool is driven by air pressure on the compressor which is connected to a car tire pressure tube (tiptop tube) then will press the mold and produce bricks according to the number of castings.

Abstract

Rice husk is a waste from rice milling that can be utilized by most people, because rice husk contains nutrients and protein. Therefore, this rice husk has many uses, one of which is used as animal feed. To make it animal feed, it requires processing in a puree way so that it is easily digested by the livestock. Seeing this problem, it is necessary to make a rice husk smoothing machine. The working principle of the rice husk smoothing machine is carried out by inserting the rice husk into the inlet funnel which will be refined by the blade, then utilizing the gasoline motor as the prime mover, where the rotation of the machine is continued by a main shaft circuit consisting of 10 blades, the shaft with a diameter of 19 mm, a bearing size of 2.5 inches, V-belt type A 41, and a pulley diameter of 10 cm, as the main components of the rice husk smoothing machine. The capacity of the rice husk smoothing machine is 2400 kg within 8 hours/day of machine operation. The results of grinding the husks within 2 minutes of testing can grind an average of 0.90 kg of fine husks with a rotation of 4815 rpm. So in a day the rice husk smoothing machine can refine 2400 kg in 8 hours or a day of machine operation.
