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

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.

Abstract

There are various methods to improve vehicle performance, including by blending fuels. In addition to bioethanol that can increase octane rating, there is the use of additives in vehicle fuels that are known to increase octane rating. With the addition of additives such as octane boosters and bioethanol, it is expected to increase the degree of ignition, reduce knocking, achieve more complete combustion, and automatically increase vehicle power.This study aims to analyze the power and torque of a four-stroke motorcycle by considering the addition of bioethanol and octane boosters to Pertamax fuel. Experimental method was used with variation of bioethanol concentration and octane booster in fuel as test parameters. This study provides insight into the potential for power improvement in the use of Pertamax fuel on four-stroke motorcycles through the addition of bioethanol and octane booster. The implications of these findings can serve as a basis for the development of more efficient and sustainable fuels for four-stroke motorcycles.

Abstract

Fuel plays an important role in vehicle performance, and octane rating is one of the main factors. One innovation is to blend the fuel with additives such as bioethanol that can increase octane and reduce emissions of pollutants such as CO, CO2, HC, and NOx. This study examines the use of an affordable and readily available blend of bioethanol and camphor as an alternative fuel. In addition, this study also aims to determine the most effective blend variation to reduce exhaust emissions. This study uses an experimental method by manipulating one or more independent variables and measuring their effect on the dependent variable. The independent variables in this study are 10%, 15%, and 20% bioethanol mixture and camphor 5 grams, 10 grams, and 15 grams in Pertamax. As for the dependent variable is the exhaust gas content with variations in engine speed of 1500, 3000, and 4500 rpm. The study data were then presented in tabular form and analyzed using the two-way analysis of variance (ANOVA Two Way) method along with the data graph. The results showed a decrease in CO levels by 19.51% at 1500 RPM and 84.13% at 3000 RPM and a decrease in HC by 37.44% at 1500 RPM and 48.68% at 4500 RPM.
