Abstract

One of the current trends is the LCGC (Low Cost Green Car), one of the LCGC cars that people are interested in is the Toyota Calya. However, like other automotive products, the Toyota Calya did not escape the complaints of its users. The complaint that is often experienced by consumers is that the rear shock absorber of the Toyota Calya has collapsed and leaked, even though the age of this car is actually not even 3 years old and the kilometers have not reached 40 thousand kilometers. In this final project, the author conducts several analyzes of what only cause damage to the shock absorber Toyota Calya. In this study, load tests and measurements were carried out on several factors that caused damage to the Toyota Calya shock absorber. From the results of the study, it was found that the damage to the shock absorber occurred due to the fatigue material in the shock absorber seal, causing oil leakage in the rear shock absorber of the Toyota Calya. The cause of damage to the genuine Toyota Calya shock absorber is due to deformation of the shock absorber spring due to the spring not being able to reduce the force load that occurs when the vehicle is fully loaded, so that the shock absorber has a stroke (shortening) that exceeds the allowable standard limit. This causes the shock absorber to last longer. One solution to prevent the Toyota Calya shock absorber from sinking is to replace the shock absorber and spring with Kayaba's after-market products. Kayaba shock absorber has a larger diameter spring wire and a larger shock absorber diameter than the genuine Toyota Calya shock absorber. The second solution to prevent the Toyota Calya shock absorber from being damaged quickly is to reduce the full load on the vehicle. To avoid deflection or sinking symptoms in the rear shock absorber of the Toyota Calya is to reduce the full load on the vehicle. This of course will extend the life of the shock absorber, because a large spring deflection would result in damage faster in shock absorber components.

Abstract

Lifting machines are used to move cargo at a location or area, department, factory, construction site, storage and unloading area. In principle, the working movement of the lifting machine is to raise and lower the load. Some lifting machines can also move horizontally, rotate, move vertically, and so on. For example, cranes can lift loads, shift, hold them up when needed and carry as specified. The formulation of the problem is to find out what is the lifting speed, power consumption and performance of the Overhead Crane with Part Botomo load at PT. PARAMOUNT BED INDONESIA. the research method uses engineering research methods and theoretical research. The purpose of this study was to determine the lifting speed, power consumption and performance generated when lifting Botomo Parts using the Overhead Crane machine at PT. PBI. In this study using 2 different rpm variations, the first uses 1000 rpm which is taken from the average value, namely the lifting speed is 6.81 m/min and the power consumption is 9.14 kW, the second uses 1,200 rpm which is taken from the average value. namely the lifting speed of 5.32 m/min and the power consumption of 6.86 kW, then this value was compared with the value of the lifting speed and power consumption in the Overhead Crane specification at PT. PBI, namely the lifting speed of 5.04 m/min and power consumption is 5.3 kW, from the results of the comparison, the performance value of the Overhead Crane engine at PT. PBI is 70%.

Abstract

Research in the field of machining in testing the level of roughness needs to be done to get good results in the machining process. The purpose of this study was to determine the effect of variations in feeding on the surface grinding process on the surface roughness and hardness of S45C carbon steel that has gone through processes including induction, quenching and tempering and to compare which feeding variation has the lowest level of roughness. The research method used is an experimental method in the form of giving a variety of feeding which is tested on 4 samples in the surface grinding process. The number of variations given is 0.2mm/min, 0.4mm/min, 0.8mm/min, 1.2mm/min. The test results obtained are in the form of roughness values and hardness values on specimens that have been previously tested. The results showed that there was a change in the roughness value that occurred during the grinding process by applying a 0.2mm/min feeding variation resulting in an average value of 1.33683333µ, a feeding variation of 0.4mm/min producing an average value of 1.27068333µ, a feeding variation of 0.8mm/min producing an average value of 1.27068333µ. the average value is 1.29633333µ, the variation of feeding 1.2mm/min produces an average value of 1.39458333µ and there is no significant change in the surface hardness value in the surface grinding process. The tools used in this study were the Mitutoyo SV2100 rougness tester to determine the roughness value, and the Sonohard SH22 hardness tester to determine the hardness value. The data that has been obtained are then analyzed using descriptive statistics where the data are presented in the form of tables and graphs. after grinding. This shows that there is an effect of giving different variations of feeding the surface grinding process to the surface roughness value.
