Abstract

The basic competencies of SMK graduates are demanded to be adaptive according to the needs of the business world and the industrial world. Basic competence is the basis for the depth of graduate competence. Community service aims to improve the basic competence of technical measurement tools for Class XII Students of the Light Vehicle Engineering Department, Ki Hajar Dewantara Vocational School, Brebes Regency. The method used was a workshop that was held on June 5 and 6 2024. The tool used to measure the success of the community service program was the implementation of evaluation at the pre-workshop and post-workshop stages. The results of the activity explained that the pre test was carried out to find out the initial condition of the participants' competence by 15%. Meanwhile, the final competency of the participants, which was carried out through post-workshop evaluation, increased by 66.67%. The provision of Refreshing material and PjBL practicum measuring tools is the key to the success of the workshop.

Abstract

The energy crisis is largely attributed to the extensive use of fossil fuels. Butanol and ethanol can be used as an alternative energy source because their characteristics are superior to those of gasoline, such as RON and oxygen content. This study aims to determine the effect of gasoline-butanol and gasoline-ethanol mixtures on engine performance so that they can be an option to replace fossil fuels. The percentage of alcohol (butanol and ethanol) in gasoline is 5%, 10%, and 15% with variations in engine speed of 1000, 2000, and 3000 rpm. This study uses a dynamometer as a tool to measure engine performance. Test results show that E15 can increase engine torque and power by up to 26%, while B15 increases by 19%. In addition, ethanol can reduce BSFC better than butanol. The BSFC value decreased by 17% in E15, while B15 decreased by 15% compared to pure gasoline. This is because ethanol's RON and oxygen content are higher, so torque and power increase while BSFC decreases. These results prove that gasoline-ethanol is better at improving engine performance than gasoline-butanol.

Abstract

The weight of a car's parts can be reduced by using materials such as aluminum. The lower arm is the main component of the suspension system, usually found at the front of the suspension in both Macpherson and Double Wishbone systems. There are AA6061 and malleable cast iron materials, where AA6061 is made from aluminum alloy, and the malleable cast iron material is made from steel alloy. Both are different in terms of material but almost similar in terms of material properties. The research method uses FEM assisted by Solidworks software and looks at the loading, stress and strain. The results of the research were that the material from AA6061 was better but more expensive if made in smaller quantities.

Abstract

The demand for non-OEM camshafts is increasing, but this raises concerns about material quality. This study analyses the material characteristics of AISI 8620 and grey cast iron camshafts used in 125cc automatic motorcycles. Testing was conducted using Metallography and Optical Emission Spectrometry. AISI 8620 exhibits a fine ferrite-pearlite microstructure and alloying elements such as chromium and molybdenum, which support heat treatment. Cast iron exhibits a pearlite structure with flake graphite, providing superior damping but less toughness. The results indicate that AISI 8620 is more suitable for high-load applications, while cast iron is suitable for lightweight and cost-effective applications. This study provides important insights into material selection for motorcycle camshaft manufacturing.
