Abstract

One of the effects of increasing the number of vehicles is the presence of scrap tires. Stacking and burial of used tires have caused serious problems for the environment. Therefore, this article presents a brief review of the potential of scrap tires to be useful materials and products. Of the many potential uses, we find at least three ways to use the scrap tires, which are: converted to rubber powder to be reprocessed as asphalt mixture, concrete mixtures, composite mixes, fillers, and the like; converted to liquid oil through the pyrolysis process; and recycled forms, where the original physical properties of used tires are still visible, such as for furniture, wave breakers, racing circuit safety, and the like.

Abstract

This article presents a research review of automotive vocational lecturers in Indonesia obtained from Google Scholar during 2016-2018. We found more than 500 articles on Google Scholar produced by 277 lecturers from automotive vocational programs. However, through data filtering, there are only 208 publications related to automotive, including the development of learning media in VHE. Looking at the world automotive research trend (which leads to major issues regarding battery systems, downsizing and turbocharging, and advanced combustion modes), and with concerns about the availability of fossil energy, major and fundamental reforms are needed for research activities in automotive vocational lecturers in Indonesia, both in terms of topic and depth of research material. As a recommendation, stakeholders in automotive vocational programs in universities should immediately form a research roadmap together and form a national automotive research consortium in order to contribute in realizing environmentally friendly vehicle technology and a sustainable national transportation system.

Abstract

In the last decade, the search for cleaner fuels like biodiesels is gaining wide popularity, and exergy analysis are widely used in design and performance evaluation to identify the various losses. In this study, three neat biodiesels are tested for energy and exergetic performance in a single-cylinder, four-stroke IDI diesel engine. The experiments are conducted for waste poultry fat biodiesel (WPFBD), palm oil biodiesel (POBD), and waste cooking oil biodiesel (WCOBD) at various loads by maintaining a fixed rpm of 1500. Parameters like exergetic efficiency, exergy destruction, and various heat loss factors are computed from the thermodynamic models. The in-cylinder combustion pressures, heat release rate, and fuel consumption are also measured. Results show that WCOBD dominates the other two biodiesels by achieving high exergetic efficiency (52.74%) and low exergetic destruction (3.74 kJ). The in-cylinder combustion pressures and net heat release for WCOBD show smoother combustion with better torque conversion. In contrast, POBD shows high fuel consumption and more unaccounted heat losses. Better utilization of heat input by converting it into useful work was achieved for WCOBD at 75 and 100% loads. Similarly, the exhaust emissions from WCOBD compared with diesel fuel at all the loads reveal that except for NOx, there is a drastic reduction of CO, UHC, and exhaust smoke.
