Abstract

Metal cutting process (cutting process) is to cut metal to get the shape and size and quality of the planned cutting surface. The metal cutting process is carried out with special tools, according to the type of cutting process. So the tools for one process cannot be used in another process, even for similar processes, the tools cannot be exchanged if the cutting plans are not the same. Lathe process is a machining process to produce cylindrical machine parts which are carried out using a Lathe. Its basic form can be defined as the machining process of the outer surface of cylindrical or flat lathe objects. Polyvinyl Chloride, commonly abbreviated as PVC, is the third-order thermoplastic polymer in terms of total usage in the world, after Polyethylene (PE) and Polypropylene (PP). Worldwide, more than 50% of PVC produced is used in construction. PVC is produced by polymerizing vinyl chloride monomers (CH2 = CHCl). Because 57% of its mass is chlorine, PVC is the polymer that uses the lowest petroleum feedstock among other polymers. This research follows up the selection of configuration of the lathe machining process using plastic work pieces. In this study, Maximat V13 lathe and PVC type plastic were used. The variation of machining processes are spindle rotation (320, 540, and 900 rpm), feeding speed (0.07, 0.14, and 0.28), the use of tool types (carbide and HSS) and cooling (without cooling, coolant, and oil). So, with this research, it is expected that the optimal parameters in determining the configuration of the lathe machining process on a PVC work piece to produce a good turning surface can be achieved

Abstract

Vibration in the vehicle body is an important factor that needs to be considered when using a vehicle. This is important because vibration can affect driving comfort and safety, both for the driver and passengers. The less vibration there is, the more comfortable the vehicle is to drive and ride. The aim of this research is to determine the variation of the coil spring on vibration speed. In this research, the approach used is quantitative with an experimental type. The independent variables include variations in coil spring diameter, namely 9 mm, 11 mm, and 13 mm, as well as coil spring length, namely 130 mm, 180 mm, and 230 mm. The dependent variable analyzed is vibration speed. Data was obtained using a coil spring load test tool and a Vibration meter to measure vibration speed. The research results show that the interaction between the diameter and length of the coil spring influences the vibration speed. The highest vibration speed was found in the coil spring with a diameter of 9 mm and a length of 230 mm, while the lowest vibration speed occurred at a diameter of 13 mm and a length of 130 mm. An interaction with a diameter of 13 mm and a length of 130 mm indicates the optimal coil spring size.

Abstract

The impact of the increase in motorized vehicles is air pollution from vehicle exhausts. Exhaust gas is a polluting substance that pollutes the air where the gas is created from exhaust gas or gas from the combustion of vehicles. One alternative way to reduce the content of harmful exhaust gases such as carbon monoxide (CO), and hydrocarbons (HC) produced by motorized vehicles is by adding a catalytic converter. In this study, the catalytic converter uses Aluminum (Al), Brass (Cu-Zn), and Copper (Cu) materials. The purpose of this study is to analyze the effect of using a catalytic converter made of Aluminum (Al), Brass (Cu-Zn), and Copper (Cu) on exhaust gas. In addition, this study aims to determine the material used as a catalytic converter in order to get the lowest level of exhaust gas. Furthermore, the research data are presented in tabular form and then analyze them using one way anova and graphs. The results showed a decrease in CO by 50% at 1500 Rpm and 59.6% at 4500 Rpm, HC by 72% at 1500 Rpm and 55% at 4500 Rpm, CO2 by 3.22% at 1500 Rpm and 7.91% at 4500 Rpm, and O2 by 5.53% at 1500 Rpm and 1.66% at 3000 Rpm.
