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.

Abstract

This paper discusses the granulator machine testing process. This test aims to determine the process of occurrence of granular. Granular pellets are one form of feed pellets, granular (rounded) and light in weight. Granular pellets are not easy to sink but are easily broken down in water. This type of pellet is made without going through the process of pressing, so that it can produce feed grains that are light weighted, not easily submerged but easily decomposed in water. The goal is to determine the optimal state of the granulator machine with three angular tilt positions, it can perform maintenance on the granulator machine. The granulator machine testing process is carried out by means of the plate angle measurement process, the water mixture measurement process, the plate speed measurement process. Material used for the testing process uses flour and water. While the tools used in the granulator machine testing process are spray, 14 key, sieve, and container. After testing at 3 angles at an angle of 25o, angle of 30o and angle of 35o the authors conclude that this machine can produce small granules at a slope of 250 with an engine speed of 17 rpm and average weight of granular which is produced 236 grams. While the results of hourly 3 kg / hour.

Abstract

Model Solar Chimney dengan ukuran 3x3 m2 luas atap rumah sebagai kolektor pelat datar telah dipelajari dalam penelitian ini. Udara panas keluaran sistem ini digunakan untuk pengeringan bahan hasil pertanian dengan sistem tray truck dryer telah dipelajari sebelumnya. Kedua sistem ini digabung untuk dijadikan terintegrasi pada daerah jalur khatulistiwa dimana membutuhkan pengeringan bahan hasil pertaniannya (contoh kulit manis, ikan, dll). Temperatur pengeringan bahan ini berkisar 41oC sampai dengan 80oC. Kondisi bahan ini dapat digunakan pada sistem pengeringan ini. Bahan yang dikeringkan berada pada temperatur pengeringannya akan menghasilkan jenis yang paling bagus dan maksimal, serta lebih bersih berada pada sistem tersebut.  Sistem ini menjadi alternatif pengeringan bahan pada daerah yang membutuhkan dijalur khatulistiwa yang masih belum memperoleh aliran listrik. Pemanfaatan energi surya secara langsung akan lebih optimal dalam kebutuhan sehari-hari masyarakat pada teknologi ini, sehingga ketergantungan dengan energi lain (minyak bumi, kayu, dll) berkurang dengan memanfaatkan sumber utama energi yaitu energi surya. Atap rumah sebagai kolektor pelat datar dan rumah pengering pada sistem solar chimney menjadi alaternatif energi untuk kebutuhan sehari-hari.

Abstract

Subject matter of this research is focused on the manufacture and research tools husk furnace fuels are useful for generating hot air speed that is used to replace electric heating element before. The flow of hot air coming from the furnace will be used to dry husks of grain. Many previous researchers who have made a husk furnace with a variety of methods and construction, replacing the material in order to produce an optimal temperature. In this paper, the authors conducted a study about how to make tools husk furnace and do research on the tool. This research looks at how adaptable tool to generate a stream of hot air. The method I use is the reset method to find the amount of insulation needed to achieve the speed of air drying temperature. Research using laboratory test equipment such as Airflow meter and thermometer. Test data is retrieved (the speed of air temperature and the amount of insulation required). Measurement methods performed directly on the object of research. Test data were analyzed by using the software Microsoft Excel. The data processing results obtained that the most optimum conditions for temperature 42.60 C, the rate of air velocity of 2.84 m/s with number five bulkheadd.
