Abstract

Sumber energy terbesar yang dimanfaatkan saat ini masih dominan berasal dari fossil. Sumber energy fossil bersifat non renewable sehingga lama kelamaan akan habis dan energy fosil juga tidak ramah lingkungan karena menghasikan gas CO2 . Oleh karena itu saat ini sangat banyak penelitian dilakukan tentang energi terbarukan agar mendapatkan sumber energy baru yang memiliki dampak positif bagi lingkungan dan bersifat renewable. Salah satu sumber energi terbarukan yang ramah lingkungan dan mudah untuk didapat adalah energi angin. Penelitian ini membahas tentang pemanfaatan energy angin sebagai penghasil listrik dengan menggunakan turbin angin savonius. Tujuan yang hendak dicapai adalah mengetahui unjuk kerja turbin angin savonius tipe U tiga sudu melalui pengujian terhadap variable ukur yaitu kecepatan angin, kecepatan putar rotor dan daya yang dihasilkan alternator. Lokasi pengujian di pantai Air Tawar Padang. Dari hasil pengujian didapatkan putaran maksimum rotor adalah 196 rpm pada kecepatan angin 7,9m/s, besar daya 126 watt. Untuk putaran minimum rotor 53 rpm pada kecepatan angin 2,7 m/s tidak mampu menghasilkan daya karena putaran pada poros alternator setelah melewati system transmisi menjadi 156 rpm sehingga tidak mampu membangkitkan listrik, dimana spesifikasi alternator yang dipakai baru mampu menghasilkan listrik jika putaran besar dari 300rpm.

Abstract

Quality Control (QC) is one of the most important components in the manufacturing process. The aim is to determine whether a product is feasible to market. One aspect of QC is the size / dimension of the object to be made. If the size is still within the range of tolerance, then it has passed the QC in terms of size, but if not then it includes a failed product. The problem encountered is that it takes a long time to take measurements, especially objects in the third dimension where each part is different as microdrill, zipper etc. To overcome this weakness, a CCD camera is used as a sensor to record images and then use LabVIEW software to analyze the size of the recorded image. This is a preliminary study so that it is only done for objects with two dimensions with square and circular shapes. From the research that has been done, the measurement with the camera gives results that are almost the same as the use of calipers where the standard deviation fluctuates from 0.3 to 23.8 for circles and 0.54 to 32.05 for squares. Furthermore, the time needed to do one measurement process with the camera ranges from 201 ms to 338 ms whereas using the calipers takes 3 to 5s

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

Abstract

The power produced by a hydrokinetic turbine depends on the interaction between the rotor and water. Therefore, the optimal rotor geometry must be designed and built to capture maximum water energy and convert it into usable energy. Hydropower is one of the potential renewable energy that can contribute to the need for electricity. Hydropower generator is pollution free so this generator can answer environmental problems and the availability of renewable energy sources. The aim to be achieved in this study is to produce a turbine hydropower with good performance if it operates on an irrigation channel and is applied as a power plant. This research was developed to get the right specifications for the use of hydrokinetic turbines in the irrigation canal area. There are several methods carried out in the design of hydrokenetic turbines, namely by designing blades based on the shape of water flow, repairing the transmission system, and selecting the right generator. In this study, we tested the sweet lemon irrigate applied and tested in the area of ​​Padang Sumbar Sweet Limes Pauh, the results obtained were that the turbine can produce power of about 12.6 watts.

Abstract

In this day and age people decorate homes with flower pots and many models of flower pot place creations. Usually the place to put flower pots in the form of a circle and to make a circular iron is made manually requires energy and a long time. A bending machine is needed to make concrete iron circle creations. The aim of this research is to produce a rotary bending machine that is able to work efficiently in forming a concrete steel circle. The method used in this study is a practical method that is doing machine design and continued with the manufacture and field testing. The working principle of this machine is to use a motor that functions to move the Gearbox and continue the rotation to the shaft, then the shaft rotates and the bending mall rotates and makes the steel concrete come round and circular. The conclusion is (a). This concrete steel rotary bending machine has dimensions of 550 mm x 550 mm x 1000 mm with an electric motor drive power source (b). The results of the bending process using a concrete steel rotary bending machine are far more efficient than doing manual bending

Abstract

Wind energy is a resource that is abundant, environmentally friendly, and renewable, therefore it has the potential to be developed. Savonius vertical axis type is suitable for application in low wind speed conditions. The Savonius wind turbine has good self-starting so that it is able to rotate the rotor even though the wind speed is low, besides that the torque it produces is relatively high. This study aims to determine how differences in OR affect the performance of Savonius turbines with an aspect ratio (AR) of 2. The experimental method was applied in this research to investigate the characteristic Cp of the model using the wind tunnel with different overlap ratios of 0.1, 0.15, 0.2, 0.25, and 0.3. The wind turbine model that has been made using a 3D printing process made of PLA + material. The results obtained in each OR test are the maximum Cp value for the variation OR 0.1, which is 0.121, OR 0.15, the maximum Cp value obtained is 0.213, OR 0.2, the maximum Cp value is 0.245, OR 0.25, the maximum Cp value is 0.224 and OR 0.3, the maximum Cp value is 0.210. Based on the five overlap variations, the maximum Cp ratio is obtained at OR = 0.2, namely Cp = 0.245 and TSR = 0.7. The OR value of 0.2 is able to maximize turbine power and minimize negative torque because the flow through the overlap area can maximally direct wind power to the maximum backward blade.

Abstract

Almost all activities are carried out with the help of technology. It is as if technology has become a basic need for human life today. Of all the areas that have made progress, machinery is the one that has had the greatest effect. Lots of machines have emerged with new innovations with very diverse functions, one of which is the Computer Numerical Control (CNC) machine. A CNC machine is a machine used in the manufacturing industry to quickly produce large quantities of components for the engineering sector. As the name of the CNC itself, every work from CNC uses a computer system that has been well formed to produce goods that are in accordance with what is desired. Departing from some of the problems above, the author concluded to make a similar technology at a much cheaper price with a more practical work system, therefore the author made a 3 Axis Acrylic Cutting CNC Machine Using a CO2 Laser Tube".
