Wind energy is a renewable alternative energy source that is environmentally friendly. As in indonesia, the wind potential is very capable of being utilized or develoved for renewable energy, whre the average wind speed in indonesia is 2 m/s – 8 m/s with the wind speed capable of driving wind turbines. Turbines have an important component, namely blades, these blades convert wind energy to kinetic energy. The purpose of the research on design of Horizontal Axis Wind Turbine Taperless type with Airfoil PSU94-097 using jackfruit wood is to determine the process of material is to determine the process of designing, manudacturing and tasting. Where starting with the selection of the airfoil is PSU94-097 with a Cl/Cd value of 138.56 and a CP/TSR value of 46%. 2D and 3D bar design are made in Solidworks software by entering coordinate to simplity the manufacturing process, namely manufacturing. The last stage is testing the blades on the wind turbine, where the total test for three days produces 371.54 Wh of power with the highest wind speed of 12.46 m/s.

From observations on molding and die casting companies as well as the production of plastic molding automotive parts, several defects were found in the injection engine results. Types of product defects include short mold, black spot, flowmark and wide flashing. This study aims to suppress the problem of the factors causing product defects, namely by calculating the heat transfer that occurs in the mold and calculating the rate of heat absorbed by the chiller which is expected to reduce product defects on the front fender of the motorcycle so that it can meet the desired production targets and can reduce production costs incurred. excess. The results showed a decrease in the mold temperature of 35°C and the melting temperature of the plastic at 220°C, which was 1.19%. And to maintain a mold temperature of 35°C with a plastic melting temperature of 220°C, the proper chiller temperature setting occurs at 28°C. It can be concluded that the cause of defects in the front fender of a motorcycle is the relationship between the melting temperature of the plastic as a raw material and the temperature of the mold used

Fabrication is the process of processing components of raw or semi-finished materials that are assembled, shaped, and manipulated to produce new goods that have added value and function. It can also be said that fabrication is a series of jobs to build something manually or with the help of automation such as using factory tools. Quality Control or commonly abbreviated as QC which means quality control. QC can be needed in various industrial sectors, from a manufacturing to a hand production. The general task of QC is to be able to visually inspect to be able to test the product. Inspection of a product can take place before, during and after the process in production. Inspections must be carried out carefully so that any material that does not meet the standards can be rejected and maintain the quality of the material sent to the site. Finally, in working on a project, you must pay attention to other factors that can affect the course of the project so that the desired standard is maintained and progress can continue.

The front Shaft of a motorcycle works to support the steering load to maintain the balance of the vehicle when walking, looking for the road and reducing speed. In this study, the engine elements will be planned based on systematic calculations and at the same time implementing, applying theory in the form of engine element structures, especially on the front shaft of the 2015 Yamaha Vixion Advance 150cc motorcycle. The data analyzed is the static calculation on the motorcycle and on the bicycle shaft. 2015 Yamaha Vixion Advance 150cc motorcycle. With the calculation of 2015 Yamaha Vixion Advance 150cc motorcycle statics, the number = V1:1231 N, V2: -59 N, V3, -859 N, M1: 860 N.mm & 837,080 N.mm, M2: 378,420 N.mm&318240 N.mm, M3: 135,760 N.mm&1.187,280 N.mm. and the results of statics on the shaft of the 2015 Yamaha Vixion Advance 150cc motorcycle the number = V1: 615.5 N, V2: 615.5 N, V3: 0 N, M1: -2160 N.mm&-39053,75 N.mm, M2 : 122484.5 N.mm&244969 N.mm, M3: 12310 N.mm&12310 N.mm

The shaft is one component of a motorcycle that is no less important than other components. These components function to support the load of the vehicle itself as well as external loads such as humans or cargo on a motorcycle.This study aims to determine the working stress and also the safety factor on the shaft.The component that will be discussed is the front axle of the Honda Vario 110 tipe CW motorcycle.The method used is an experimental method with qualitative and quantitative analysis.The results of the analysis show that if a load of 80 kg is given, then the value of the working stress is 163,28 N/mm2, while the safety factor is 2.1.

Plastic is a material that can be used as a substitute for metal, this is because the material has advantages, such as light weight, corrosion resistance, and relatively cheap price. There are several types of plastics such as polyethylene, teflon, polysulfone, polypropylene, acrylonitrile-butadine-styrene (ABS), and so on (1). ABS plastic is the most widely used material for chrome plating. The butdine portion is evenly distributed in the acrylonitrile-styrene matrix, making ABS plastics have advantages such as metal being easier to stick to the substrate, low coefficient of thermal expansion, easy to print, and improved aesthetic appearance (2). Behind the advantages possessed, ABS plastic has weaknesses including hardness, less high friction resistance, and at low temperatures it is easy to damage. To overcome this deficiency, one of the methods used is by electroplating the krum, with variations in temperature, 40°C, 50°C and 60°C, as well as variations in lectroplating time of 10 minutes, 20 minutes, and 30 minutes. . The tests carried out are measuring the adhesive strength of the coating results and the thickness of the layer. The results showed that the temperature and time in the electroplating process affected the adhesion of the coating and the thickness of the layer, where the highest value of adhesion was the variation of time of 30 minutes and a temperature of 40°C with a value of 0.41 MPa and the lowest value of adhesion at a time variation. 10 minutes and a temperature of 60°C with a thickness value of 0.06 MPa. And the highest thickness value is with a time variation of 30 minutes and a temperature of 60°C with a thickness value of 35 m and the lowest thickness value at a time variation of 10 minutes and a temperature of 40°C, 50°C with a thickness value of 20 m
