Abstract

Various assumptions circulating in the community about the use of fuel types on motorcycles, among others; First use of a conventional motorcycle with a low compression can help clean the burn chamber, improve the performance of the engine, and no difference the perceived premium fuel users have on the EFI motorcycle with the compression Lower. The angapan caused the user to prefer Premium fuel due to a more economical price. This study was conducted to determine the influence of fuel usage on machine performance with multiple criteria. There is a treatment applied to the research object, so to get the desired data on this research using the experimental method. The resulting power drop occurred on the use of premium and pertalite fuels when compared with the power generated on the use of first fuel. The biggest power decline occurred in the comparison of power between first fuel with premium with a large decrease of 4.32%.

Abstract

Car air conditioning system simulator is a tool that can be used to learn the mechanism of action and the performance of the air conditioning system with certain treatments. The purpose of this research is to be able to design, make a simulator of air conditioning system type of orifice tube car with R134a cooling fluid to determine the mechanism of action, and analyze the performance of system using R134a cooling fluid. This research is a type of Research and Development (R & D), with the ADDIE model development procedure. Based on the results of research conducted, the final product is a valid and practical Car Air Conditioning System Simulator. Coefficience Of Performance (COP) value  = 4.88, and has a practical value of 93 %.
