Perancangan Pintu Ruang Start Arena Pacuan Kuda Menggunakan Sistem Pneumatik
Get PDFStarting gate door is a tool used horse racing arena that serves as a star or space to take off before darting run to racetrack. Doors starting gate consists of a variety of forms and working method, from the manual to which use the automatic system, such as; mechanical, hydraulic, electric and pneumatic systems. Starting gate door with pneumatic system is a tool that is used to open and close starting gate door, the way it works is that a pneumatic cylinder is installed on the door, then pneumatic system functions to open and close the door. Pneumatic system is a tool that uses air as an energy source, components required in the pneumatic system: compressor or air supply unit, or air processing unit (Filter, regulator, and lubrication), regulator or valve unit and the main thing is the pneumatic cylinder serves as a tool which converts compressed air energy into mechanical energy (linear motion of the cylinder rod). In this study aims to be able to get the shape of the starting gate door using a pneumatic system, which can be used as a reference in making the actual door, so that in its application on the racetrack it can be used easily and the time it takes to release the horse becomes faster and the time it takes to release the horse becomes faster. From design results, it is known load that will work on the pneumatic cylinder is 4703.5 N, the inner diameter 100 mm, diameter cylinder rod is 25 mm, total air consumption required is 4,6 liter, compressor discharge is 0,39 liter/second, and compressor power is 0,5 HP

Pengaruh Overlap Ratio pada Model Turbin Savonius terhadap Karakteristik Koefisien Daya Berdasarkan Eksperimen Pada Wind Tunnel
Get PDFWind 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
