Abstract

Nowdays, Alumunium is widely used and utilized in industrial activities because of light properties and having well mechanical strengths. The use of alumunium does not only limit on the use of new alumunium, but also the used one. The main purpose of this research, i.e., (1) testing of physical and mechanical properties of Al-Zn7 from the fussion of Crucible furnace; (2) analyzing crucible furnace of the Al-Zn7 fussion by comparing to the result of the first and second fussion. The method of this research was experimental research with the average value of each the first casting was 49,2 HRB and the second one was 50,3 HRB. Based on the test result showed that the quality of crucible furnace was good because it did not experience the significant changes.

Abstract

This research aims to; 1) Designing and making aluminium melting crucible casting with the capacity15 kg; 2) Conducting the test of chemical composition of the first and second melting result. Theresearch used field and library research. From the result of the design, it could be obtained that thedimension of melting casting has 547 mm diameter, 3 mm thick, 410 mm high. Whereas, molten cup has 178 mm diameter, 8 mm thick, and 230 mm high. The result of the first melting chemicalcomposition test and the second one do not work out a significant change. The material of the firstmelting result still contains 89,52% of aluminium (Al), while the main fusion is 7,71% of zinc (Zn)and 1,84% of silicon (Si), and in the second melting result still contains 89,55% of Alumunium (Al),while the main fusion is 7,51% of zinc (Zn) and 1,94% of silicon (Si).

Abstract

In this article the author conducts research related to energy consumption studies on electric motorbike vehicles (SEMOLI) made and developed by the author. The purpose of the energy consumption study is to determine the energy consumption of electric motorbike vehicles that have been made for further improvement and development. The method used is experimentation with the first phase testing on a straight flat road for one kilometer with flat road conditions, this phase of experimental results shows an average energy consumption of 30 Wh, for an average uphill road consumption of 40 km / h and for the second phase of experimental data using experimental methods with speed parameters 30 - 35 km energy consumption has an average of 30 Wh, at speeds of 40 - 45 km / h energy consumption has an average of 28 Wh, and 50-55 km / h average energy consumption of 27 Wh. The test results show that on flat road conditions and the increasing speed, the energy consumption will decrease.
