Abstract

This study aims to determine the ratio of power and torque on an automatic motorbike using two different rollers, namely a cylindrical roller with a sliding roller with a weight of 12 grams each. The method used in this research is the experimental method. The testing and retrieval process carried out at the Gede Widi Motor workshop, and data collection was carried out five repetitions for each variation. After testing, there are differences in torque and power on the cylinder roller with roller sliding. The cylinder roller reaches the highest torque of 7.6 Nm at Rpm 4000. The highest power is 7.46 Hp at Rpm 7000, while in roller sliding, the highest torque is 11.82 Nm at Rpm 4000 and the highest power 7.56 Hp at 7000 RPM.

Abstract

This research aimed to (1) Determining the differences in power and torque to use of a coil standard, a copper, and silver wire ground strap variation coils. (2) Determining the color characteristics of the sparks' size generated from the use of standard coils, variation coils of copper, and silver ground strap. This research used an experimental method. The data analysis technique used descriptive analysis, namely, observing and recording the test results and then concluding in tables and graphs. The test results show that an increase in power, and torque is generated in this test. The highest results were obtained using a silver ground strap variation coil with a power of 11.3 hp and torque of 12.05 Nm. In this case, the percentages are 7.6% and 7.8% from the lowest results of the standard coil. There are different colors, sizes, and characters obtained in the test of sparks. The dark blue-purplish sparks color is obtained from the silver wire ground strap variation coil, which can increase motor performance in a motorcycle. These results suggest that the ground strap on the spark plug coil wire can provide an increment in engine performance.

Abstract

Cooling media is a substance that increases the hardness value of a material through a heat-treatment process. This study aims to determine the effect of cooling media on the hardness of ST 37 steel due to Gas Tungsten Arc Welding (GTAW). The independent variables, namely water cooling media, seawater cooling media, and oil cooling media, while the dependent variable is the hardness. The specimens using water cooling media, the hardness in the weld area is 47.19 kg/mm2, in the HAZ area the it is 54.6 kg/mm2, and the base metal gets a value of 40.87 kg/mm2. While the specimens with seawater cooling media get a value in the weld area of 76.37 kg/mm2, in the HAZ area it gets a value of 83.89 kg/mm2 and the base metal gets a value of 70.13 kg/mm2. The specimens with oil cooling media the value in the weld area is 40.77 kg/mm2, in the HAZ area it gets a value of 43.32 kg/mm2 and the base metal gets a value of 36.09 kg/mm2 . From the hardness values obtained, specimens immersed in seawater cooling media have the higher hardness values compared than water and oil cooling media.
