Abstract

The design of wind and solar power generators is the goal of utilizing solar thermal energy and wind speed on the coast. To get a design result that is in accordance with the power requirement of 720 W, therefore the results of this design have followed the steps in the VDI 2222 method. From the results of the calculations that have been carried out the Savonius type wind turbine uses an L-shaped profile, with a diameter of 710 mm and a height 592 mm can produce a power of 279.072 Wh. And for the power generated from a Polycrystalline type of solar panel with a capacity of 50 Wp as much as 1 unit can produce a power of 467.5 Wh. Based on the calculation results of the combination of wind turbines and solar panels, a power of 746.6 is obtained. So that with this power it meets the capacity of the power requirement of 720 Wh. From the results of the calculation of the strength analysis of the material on the turbine shaft with material type SS 304 using SolidWorks software, it is known that the allowable stress on the material SS 304 is 200 MPa, then the resultant torsional stress with a load of 1217 Nm produces a yield strength of 1.723e+002 N/mm2(MPa), and the max torsional stress is 1.723e+000N/ mm2 (MPa).

Abstract

In the era of the use of technology that is currently developing. Has a major impact on the use of fiber as a composite material. One of the widely used fibers is coconut coir. Coconut coir is a natural fiber material that can be an alternative choice in the manufacture of composites. The purpose of this study was to obtain optimal tensile test values of coco fiber composite materials with variations in volume fraction of 3%, 5% and 7% and fiber lengths of 10 mm, 15 mm and 20 mm. This study analyzes the effect of variations in the volume fraction and fiber length of coconut coir with a polyester matrix on tensile testing using the Taguchi method. This tensile test was carried out using the ASTM D638 standard with the hand lay-up method. Factors that affect the tensile strength of coco fiber are volume fraction and fiber length. The combination of levels of factors that produce the average value and variance of the tensile strength of coconut coir fiber, namely the volume fraction factor (B) level 1, namely the volume fraction of 3% with a value of 30.933 and the fiber length factor (A) level 2, namely the fiber length of 15 mm with the most optimum value of 29.633.

Abstract

Technological developments and advances in the industrial sector have led to the increasing use of metals. This condition causes the availability of metal raw materials to decrease. Overcoming this, the use of composites in the industrial world is a solution. Many composite reinforcing materials use natural fiber materials are often used because they have advantages in strength and stiffness that are higher than other engineering materials. In this study using a factorial experimental method that looks at the effect of the composite ratio (volume fraction) with the use of 2 natural fiber mixtures, namely resam fiber and areca nut on impact strength. This study aims to determine the average difference in each treatment carried out in the impact test. The volume fraction treatment variants used in this study are 25%; 30%; 35% resam fiber and 10% areca nut fiber with a long soaking time of 2% NaOH mixed fiber for 2 hours with the α value used is 5%. It was found that in treatment 1: 2 the average value is different while in the treatment of 2: 3 and 1: 3 the average value of the variables is not different.
