This research aims to design and build a Darrieus wind turbine with three blades on a laboratory scale. The Darrieus wind turbine was chosen because of its efficient design in utilizing wind speed to produce mechanical energy. The research methodology involves several stages, starting from designing turbine blades that use PVC pipes that are heated and formed into flat plates, to designing turb…
The use of wind turbines to convert wind energy into electric power is one strategy to produce renewable energy. As the price of fossil fuels (non-renewable energy) such as fuel oil continues to rise around the world, it is important that we learn to make more informed decisions about energy use. This study used vertical type propellers as many as 3 blades and 5 blades with a plastic thickness …
Electricity is a primary need for all humans. Electrical energy can be converted into mechanical energy or opposite it by using an electric machine. The electric machine used in this research is a direct current motor (DC motor). When used as a mover, a DC motor not only produces mechanical energy but also dissipation energy called heat so that the DC motor can potentially overheat. Overheat ca…
The main source of electricity in Indonesia is electric power from the stateelectricity company (PLN). Often there are power outages that occur due todisturbances in the electrical system itself or external factors such as weatherconditions and animal disturbances. To anticipate the loss of electrical energy byPLN, a generator set (genset) can be used to replace the lost source of electricity. …
Along with the development of technology Prototyping. Rapid prototyping , there is an application called Rapid involves a 3D process in which the desired object is built layer by layer through an additive fabrication process. Technology that makes objects through computer programs by combining and compacting powders or filaments without any machining process, the technology is 3D printers. FDM,…
The innovation being developed at this time is an aircraft propulsion engine with the working principle of a gas turbine that can accommodate large-scale aircraft (Boeing, Airbus, etc.) as well as high-speed fighter aircraft (supersonic and hypersonic) which include Turbojet, TurboFan, Turboprop, Turboshaft and other modifications. For this type of TurboFan aircraft engine, air is required to e…
Along with the times, DC motors are widely used in all fields that aim to provide convenience in everyday life. Controlling the speed of a DC motor requires a control system that is precise, easy to control and presents data in real time so that the results are as desired. In this study, controlling the speed of a DC motor uses fuzzy logic control. Fuzzy logic control does not require complicat…
Penggunaan kendaraan bermotor di Indonesia sangat tinggi sehingga berdampak pada kelangkaan bahan bakar fosil. Salah satu alternatifnya menggunakan bahan bakar campuran etanol. Pengujian dilakukan pada mesin sepeda motor Honda Vario Techno 125 PGM-FI dengan bahan bakar pertamax dan bahan bakar campuran pertamax-etanol E50. Pengujian ini menggunakan variasi saat penyalaan yang pada awalnya 8o po…
Sugar is one of Sembako or Nine Staples. In South Sumatra itself, there is PT. Cinta Manis which is a sugar company. The sugar industry in Indonesia uses a semi-modern concept. This can be seen from the milling system starting from the sugarcane plant to the final process of becoming liquid sugar in the process. The purpose of this study is to make a DED or Detailed Engineering Design from a Ro…
