Abstract

Iron precious metals have been used since antiquity, although those with lower melting points, which were used earlier in human history, pure iron are relatively softer but cannot be obtained through smelting. This material hardens and is significantly strengthened by carbon impurities, especially in the smelting process. With a certain proportion of carbon (between 0.002% and 2.1%) it will produce harder steel than pure iron which may reach 1000 times. Iron compounds have many benefits in daily life. Iron has a very high economic value so many people make iron as a business land. Most of the usefulness of iron is in the world of construction. Many material elements are used in the world of iron-based construction because the strength of the modified iron is more beneficial and useful. This is because the cast properties of this alloy are classified as good, in addition to corrosion resistance and easy to process machines, alloy types this is widely used in the automotive industry object used is the LGX Toyota kijang alloy wheels. In this study, to obtain data, several tests were carried out, namely Heat Treatment, Quenching, Aneling, composition testing, and tensile testing. The results showed that the effect of heat treatment and quenching on iron alloy specimens was the increase in the value of hardness and tensile strength values, when compared with non-heat treatment specimens. While the strength of the pulses is not measurable because the specimens are too brittle .

Abstract

This study aims to evaluate the need for a sun gear in the rear axle of the Land Rover, which is difficult to source domestically. The research focuses on determining the appropriate size, suitable materials, and specific details. Quantitative analysis is conducted to recalculate and obtain the required dimensions. The research concludes that the appropriate size has been determined through meticulous calculations, enabling the fabrication of a sun gear suitable for the Land Rover. This study is crucial due to the urgent need for spare parts to ensure the smooth progress of Taruna's basic driving training

Abstract

The research that I made discusses the transfer of energy sources from premium to bioethanol because the facts in the field state that the use of premium fuel is increasing, this great need is faced with threatening problems, namely as we know that premium is included in non-renewable natural resources so that one day it will run out and there are no other energy sources one day there will be a need for renewable energy sources that are abundant and have more environmentally friendly properties, for that bioethanol is the alternative that I choose. because bioethanol has many benefits compared to using gasoline, including:  More perfect combustion, exhaust gas becomes clean.More spontaneous and light traction  Smooth engine, safe for catalyst engines. Fuel efficient up to 20%  Extends engine life ,Higher octane number,Gasoline-fueled motors when filled with 80% premium + 15% Bioethanol will produce engine performance that is almost the same as being filled with premium fuel and will even produce better engine performance. so that research on the comparison of bioethanol can be developed for research, the results of which are expected to be useful for the Indonesian Army.
