Abstract

This paper discusses the use of alternator cars into home electricity. This paper aims to overcome the energy crisis by reducing dependence on fossil energy sources by utilizing alternative energy sources or by developing technology in the form of alternator modifications, and also from this paper we can find out the optimum conditions of rotation and generating electricity. The workings of this alternator modification tool so as to produce electrical power that is using a motor as a drive connected to the alternator produced mechanical energy converted into electrical energy and from this alternator a voltage of 12 volts comes out and goes into travo to increase the voltage to 220 Volts. From the results of the testing of this final project, the effect of rotation on the production of electrical energy coming out on this alternator modification tool is if the rotation produced is high then the power output is also good and if the rotation is slowed the power coming out will also be small. The optimum condition of this test is at 1600rpm. Key words: keywords are written in 5 words which should be a subset of paper titles, written using lowercase letters except for abbreviations, and separated by comma punctuation for between words.

Abstract

Starting from the events on the island of Sumatra that often experience forest fires and result in the emergence of smog that can disrupt the respiratory tract in living things, especially in humans. Thus resulting in the emergence of diseases such as ispa, shortness of breath, and other diseases. This is caused by polluted air because the concentration of oxygen (O2) is only a few percent compared to air containing carbon dioxide (CO2), carbon monoxide (CO), sulfide (S2) and other combustion substances. The smoke sensor is useful for activating the fan on the smoke filter tool automatically, the Fan functions as a smoke suction to be forwarded to the room where the smoke is filtered. The workings of this tool are, when the sensor reads the smoke content on the tool more than 140 ppm, then the relay connected to the fan will activate and make the fan spin. After the fan or fan lives, then the smoke will be sucked into a tube, where the tube has a small hose at the end, then the smoke is released at the end of the hose, where the end of the hose is soaked in a container containing water, where the air will be filtered. The results of the filter are sucked back by the fan or fan in another room. If the smoke level has fallen below the threshold of 140 ppm, the fan will automatically die.
