Abstract

Energi listrik merupakan elemen penting dalam berbagai aspek kegiatan manusia. Kebutuhan listirk ini meningkat dengan meningkatnya populasi manusia. Solusi yang dapat diberikan dalam masalah ini adalah energi terbarukan, salah satunya adalah energi angin. Untuk memanfaatkan energi angin, perlu untuk mengetahui potensi angin di daerah yang akan dipasang pembangkit. Penelitian ini akan membuat alat ukur kecepatan angin yang dapat mengukur dan merekam data angina dengan menggunakan optocoupler. Alat ukur ini juga dilengkapi dengan sistem SMS untuk akses datanya dalam jarak jauh. Sehingga alat ini dapat berfungsi bukan hanya sekedar pengukur kecepatan angin tetapi juga bisa mengirim data kepada operator melalui SMS. Dalam penelitian ini, mikrokontroler yang digunakan adalah Arduino Mega 2560. Selanjutnya, alat ukur hasil rancangan dibandingkan dengan alat ukur standar sebagai validasi. Berdasarkan hasil pengujian meninjukkan bahwa alat ukur kecepatan angin berhasil dibuat dan dapat digunakan untuk mengukur potensi angin

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

Sanding work is a stage that is carried out before entering the finishing process to remove defects and smooth the surface of the object. The main purpose of making sanding machines with this mechanical belt system is to help and simplify the sanding process. The method for making sanding machines with mechanical belt systems is: needs analysis, problem analysis and specifications, problem statements, concept design, technical analysis, work drawing and tool testing. The results of the design of the sanding machine with a mechanical belt system are obtained in the form of a design with a working drawing of a sanding machine with a mechanical belt system. The sanding machine with a mechanical belt system has specifications that are 500 mm long, 350 mm wide, and 1400 mm high. The source of driving the sanding machine with a mechanical belt system is an electric motor ΒΌ HP with 2800 rpm rotation. The transmission system uses pulleys. The sanding machine with a mechanical belt consists of several components, namely the engine frame, electric motor, pulleys, tables, belt aplas, and adjustment of the belt strength of the sandpaper. The belt pulley used is from ST 37 with a diameter of 25 mm and pulley rotation of 2800 rpm. Frame construction uses hollow iron measuring 40x40x3 mm from ST 37 material. The table uses 590x150 acrylic material.

Abstract

The 4 stroke (4 cylinder) gasoline engine ignition system simulation based on the Arduino Uno microcontroller was designed as one of the modeling of conventional ignition system modification into an electronic ignition system based on the Arduino Uno microcontroller. Conventional ignition systems are modified by removing distributor components and replaced with microcontrollers as ignition system controllers. Spark plug and coil cables are replaced with Igniton coil that uses Igniter. Arduino Uno microcontroller is used as a controller that receives signals from the optocoupler sensor and activates the module relay so that the electric current enters the Ignition Trigger, the voltage needed by Igniton Trigger is 2 V by using a step down transformer to reduce the voltage. So that the Ignition Coil is active and produces a high voltage so that it can produce sparks on each spark plug. This Arduino Uno microcontroller processes data received from an optocoupler sensor

Abstract

This cracker dryer is made considering that there are still many cracker industries that use solar thermal energy directly to dry raw crackers before the frying process, so that the cracker production results will decrease due to inefficient drying process, therefore all obstacles are always experienced when using energy sunlight can be overcome by using a cracker dryer using gas (LPG). This cracker dryer has dimensions of length 550 mm x width of 450 mm x height of 1000 mm and size of drying rack with a length of 500 mm x width of 400 mm x height of 25 mm. This tool has 4 drying racks with a capacity of each rack 1.5 kg. This dryer uses the principle of convection that is utilizing heat energy generated from the heat of the fire produced through a gas-using stove (LPG), the radiated fire produces heat that enters the drying cabinet. Hot air is locked in a drying room, so that the heat can help the drying process of crackers
