Abstract

Thermoelectric Generator (TEG) is a technology that can convert heat energy into electrical energy directly due to the difference in temperature between the hot side and cold side of the thermoelectric module, known as the Seebeck effect. This study uses a thermoelectric module of the SP 1848 type. An aluminum plate is used as a medium for absorbing heat from a simulated iron temperature with a maximum temperature of 75°C, while the cold side of the thermoelectric module uses a heatsink with a temperature of 33°C and a fan. From the tests carried out, the maximum voltage produced when two TEG modules are connected in series is 1.65 Volt with a temperature difference of 43.13°C. The maximum current generated when two TEG modules are connected in parallel is 3.52 Ampere with a temperature difference of 42°C.

Abstract

The best quality of a component is a smooth surface. To achieve an optimum response, the variable setting of the process must be correct to be effective. SKD 11 steel includes the kind of tool steel that is frequently applied in the manufacturing industry as cutting tools, shear blades, stamping tools, punching, dies, and so on. Therefore, it is expected to have good surface roughness. This research will use a combination of variables to process spindle, feed rate, and cooling. The method used was experimental methods with tuning parameters. Based on research shows the most optimum gross response value was the 1600 RPM index, the rate of 120 mm per minute, and the cooling type of dramas. Variables that contribute significantly to the total variance of rudeness are the feed rate of 67.43 %.

Abstract

Brazing is a method of joining metal materials through a heating process using an adhesive or filler that has a lower melting point than the melting point of the material to be joined. Oxy-acetelyne welding is a manual welding process where the metal surface to be joined is heated until it melts by an acetylene gas flame through the combustion of C2H2 and O2 with or without filler metal where the joining process is without pressure. In this study using an experimental method. The purpose of this study was to determine the impact strength of low carbon steel after the brazing process with variations in flame and root gap. The variations of the flame used are oxidation flame, neutral flame and carburizing flame with a root gap of 0.4mm, 0.6mm, and 0.8mm. The material used in this research is mild steel St37. The added material used is 3mm diameter brass wire. From the research that has been carried out, it shows that the energy absorbed and the impact value on welding after calculation with the highest value on a neutral flame with a Root gap of 0.8 and the lowest value on a carburizing flame with a Root gap of 0.4.

Abstract

ABSTRACT The reason for conducting this review is to determine the effect of alkalization on the tensile strength and elasticity of composites of bamboo fiber and coconut fiber with a polyester matrix by varying the NaOH with concentrations of 0%, 2%, and 5%. Alkalization is one of the modifications of natural fibers to develop a compatible fiber-matrix. This exploration strategy uses the hand lay-up technique. In the main cycle, bamboo fiber and coconut fiber were treated without alkalization or 0% alkalization and in the next interaction, bamboo and coconut fiber were soaked in water (2% and 5% NaOH) for 2 hours. Then, at that time, each treatment process was formed into a composite according to the standard tensile test of ASTM D638 – II. The volume portion of bamboo fiber is 15%, coconut fiber is 15% and polyester resin is 70%, and the arrangement of bamboo fibers and coconut fibers is arranged horizontally. The matrix used in this study is a polyester resin matrix of type 157 BTQN with 1% MEKPO hardener. The highest concentration from this review showed that bamboo fiber and coconut fiber composites with NaOH variations of 0%, 2% and 5% respectively had tensile strengths of 34.9 MPa, 34.9 MPa and 54.74 MPa. The highest concentration with 5% NaOH produced the highest tensile strength of 54.74 MPa, while the coconut fiber composite without alkalization had the lowest tensile strength of 34.9 MPa.

Abstract

The ball balance robot is one of the dynamic balancing robots. This robot must be actively controlled to stabilize it so that it remains balanced perpendicular to 0˚ above the ball on the ground or floor. The control system used is the PID control system. The tests carried out include sensor testing, motor testing, robot response testing, and the implementation of the PID control system on the robot. Of the various tuning methods tested on the robot, the manual tuning method gives the robot a slightly longer fall time of 320ms, compared to other methods, namely Ziegler-Nichlos=70ms, CHR Overshoot 0%=170ms, CHR Overshoot 20%=160ms, and Cohen-Coon =150ms. Overall data processing is processed by the Arduino Mega2560 microcontroller which receives angle readings from the MPU6050 sensor as input and actuation on the stepper motor as output for balancing on the robot.

Abstract

Friction welding is a welding technique that melts metal. Jointing of metals by utilizing the heat generated by friction between metal surfaces in which variations in the pressure distance are determined. The purpose of this study is to determine the strength of the welded joint after the welding process by using variations in the pressure distance of 3mm, 4mm, and 5mm. The material used in this research is carbon steel S45C shaft. Studies have shown that welding at the deepest compression distance produces a very strong welded joint, the greater the stress during the welding process, the stronger the joint in the welding. Welding with compression distances of 4mm and 5mm. and the impact price is higher compared to the 3mm pressing distance.

Abstract

Large material removal rate and minimal surface roughness are the desired objectives in the CNC MORI SEIKI MV40–m process with the right process parameters to obtain a large material removal rate response and minimal surface roughness. The parameters used are cut speed, nutritional depth and spindle speed. The experimental design used based on the response surface methodology method in the form of a behnken design box. The experiment was randomized as many as 3 replications to produce more optimal results. The results showed that for parameters that contribute greatly to material removal rate and surface roughness is cutting speed and depth of cut. To obtain a large material removal rate, the cut speed is set at 143.28mm/min and the depth of cut is set at 0.25mm with a yield of 4.694mm3/minute. And to get the minimal surface roughness value, the cut speed is 118.05mm/min and the depth of cut is 0.15mm with a yield of 0.964 μm.
