Abstract

In this study modifications to the cutting knife and rotational speed were carried out. With blade variations of 2mm, 3mm and 4mm and rotational speeds of 300, 900 and 1500 rpm. After the research process is carried out, the noodle product tests include the length of the noodles, thickness, and elongation values. For testing, the length and thickness of the noodles used a measuring device ruler and calipers and testing the value of elongation was done by tensile tests. The results of the study showed the percentage shrinkage of 0.0% noodle dough weight. This shows the test equipment is working optimally. The faster the rotation of the motor the difference between long and thick noodles tends to increase. This shows that the rotation speed influences the performance of the flattening machine and noodle dough cutter. The faster the motor rotation, the elongation value of noodles tends to decrease. This is due to the rotation speed of the motor that affects the occurrence of broken noodles. The greater the size of the noodles the risk of breaking up the noodles decreases. The faster the motor rotation, the greater the capacity produced.

Abstract

The development of technology today is very fast especially in the sector of ease in using a tool to help human activities one of which is generator set, when there is a problem in the needs of electricity use this tool is very helpful. But in the use of this tool produces a noisy sound. Noise is a problem that can interfere with physical health at risk of hearing loss. Various technical efforts are done to reduce noise levels such as changing the number and diameter of the silencer holes that can decrease the sound produced by the generator well. The purpose of this research was to gain the influence of the number and diameter of the silencer hole against the resulting exhaust noise engine. The research was conducted with experiments, a variation of the number of silencer holes amounted to 18, 23, and 28, while the silencer diameter was used 2mm, 3mm, and 5mm. Noise level measurements are conducted at a distance of 1 meter, 2 meters, and 3 meters from Sound source using a sound level meter. Data retrieval is performed every 1-minute interval using the Stopwatch tool. With the results of the number of holes 23 and hole diameter 2mm that can reduce noise well.

Abstract

The research was conducted with experiments, with variations in the corners of the foot kick inside and outside. The angles used are 250and 350 w with foot swings of 450, 600 and 750. The result of this study showed that the greater the angle of the swing leg then the result of the leg swing against the ball would be faster the rate of the ball because the angle of a large leg swing would produce a large force or force. While the angle of the intersection of the foot is greater the angle of the resulting deviation will be the greater angle. The outer and foot kicks in differ as they kick using the straight leg of the ball will go straight by the pace of the balls whereas if using the outer foot will turn his ball or stray towards the specified kick.

Abstract

Mild steel is one type of conventional roof frame replacement that is usually made of wood. The roof frame is increasingly used and more also in the market with various qualities and prices offered. The lightweight steel frame started replacing the wood that was from before until now already used for a skeleton on the roof building house, researchers aim to get a strong test result of weight lifting against mild steel. The cantilever test I used is a one-sided cantilever test. Where the test uses a one-sided clamp focus aimed at the steel to be tested can be hung. The results showed that the average on Lendutan resulting from the three variables in the cantilever had varying levels of cutaneous. The first variable with an average of 1.45 mm Lendutan, the second variable with an average 2.07 mm leading, the third variable with an average 2.52 mm leading. From the results of a three-variable comparison, that the lowest degree of solidity is found in the wedge material with the form of lath X with a yield of 1.45 mm of sloth.
