Abstract

Recent days, more and more people are becoming interested in "free-energy". "Free-energy" means the energy sources used freely without to pay. The sources of "free-energy" are sunlight, rainfall, wind energy, wave power, and tidal power. There are other sources of power such as gravity, electrical charge in the atmosphere and ionosphere, and a mass. FESS (Flywheel Energy Storage System) is an attempt to store kinetic energy generated from the rotation flywheel in which the electrical power output from the generator as an input to the motor. Mass flywheel greatly affects the amount of power generated by a generator which will serve as a flywheel device or distributors of energy while at the induction generator to eventually convert mechanical energy into electrical energy and vice versa. In this system design becomes very important for the flywheel can store the kinetic energy. This research aims to design and build mechanisms as a means of comparison FESS flywheel effect of the geometry of the kinetic energy generated. The research method is done by making three different geometric design flywheels, and then analyzed with the help of FESS. From the experimental results, flywheel 1 with a ringtype web-concave generate kinetic energy of 312.30 J and specific energy of 31.23 J / kg, at the flywheel 2 which is type-straight arm kinetic energy gained by 316.73 J and energy specific of 31.67 J / kg and flywheel 3 with a ring-type web-straight kinetic energy obtained by 284.997 J and specific energy of 28.49 J / kg. From the research data we can conclude that each design geometry flywheel has a different contribution to the performance of energy storage.

Abstract

Waste is one of the many social problems faced by the community. To solve the problem of waste required a technology to process waste itself. Several studies have been done, one of which is design and construction thrasher machine. There are several studies on the design and construction thrasher machine. However, the analysis was conducted on one type of thrasher machine with a particular waste material. This study aims to obtain the results of the efficiency analysis of the thrasher machine results on the type of thrasher machine and waste material. The method used is experimental method. The type of thrasher machine and waste material used as a free variable. The percentage of the chopping result is chosen as a variable depending on the speed of rotation and thrasher time as the companion variable. The results of this study based on the results of experiments, both qualitatively and quantitatively shows that plastic bottle trash has a suit with shear type, grass litter has a match with the type of swing and trash has a match with the type of crusher.

Abstract

Palm brondolan are the outer fruit of the loose bunches and fall to the ground. Palm brondolan is used as a feed ingredient. Processing of palm brondolan for feed ingredients needs to be done by the process of damaging the material structure. This study aims to determine the quality of palm brondolan crusher using standard cutting eyes and determine the right shaft. In this study the crusher machine was designed using 13 circular cutting eyes to see the standard ? 4? x 1.75 mm, the number of teeth 40 pieces and the distance between cutting eyes 5 mm. This machine uses a source of driving power in the form of a 3 phase electric motor with 3 HP power and has a rotating speed of 1420 rpm and a rotation ratio of 1: 1 shaft. This study uses the experimental method, by comparing the shaft test with the quality of the palm blended crusher. The quality characteristics that are addressed are the smaller the better. The results of the study, obtained an effective engine capacity of 30 kg/hour. The quality of the crusher at 700 rpm shaft speed accelerated the size of coir length from 1 to 30 mm and the volume of shell and seed granules 8-27 mm3 while in shaft rotation 1420 rpm the size of 1-20 mm coir and the volume of grain and seeds 4-12 mm3 were obtained. From the results of the experiment proving that circular cutting eyes see the standard capable of destroying palm leaflets and shaft rotation affect the quality of the crusher. The 1420 rpm shaft rotation has a better crusher quality compared to 700 rpm shaft rotation.

Abstract

In this research, the technology that will be developed relates to a wheelchair steering and alignment system that will be used in the framework of an electric car for wheelchair users (Wheelchair car) in daily accessibility. Wheelchair car and modification vehicle shown technology development to support their rights. Duration of access for existing modification vehicle needs more than 20 seconds since opening door through to turn the vehicle power on. Wheelchair Jig design with guide bar and fixture design with locator system locked by door closing achieve 8 seconds to access wheelchair get trough into cabin. This is 7 seconds faster than modification vehicle and 4 seconds longer than user with standard car.

Abstract

The increase in ????oil palm plantations has an impact on increasing plantation waste produced, one of which is palm oil and has a positive impact on the development of palm oil waste processing technology. Palm kernel crushing machine as one of the supporting animal feed productions can produce shreds with fiber and cake dimensions that are suitable for animal feed. However, the types of livestock require varying dimensions of fiber and meal chips. The purpose of this research is a more effective completion of the project 'Design and Analysis of Palm Oil Palm Oil Counter System with 3D FDM Product Spacer Cutter Thickness'. The design process of a machine component must consider the stresses and deformations that occur so that it can be known whether the components designed are of good quality or not. The five steps of the problem-solving process are as follows: 1) Define requirements, 2) Gather/analyze information, 3) Develop several options, 4) Select the best option, and 5) Implement the design. Design simulations and analysis were carried out on the components of the chopping shaft, spacer cutter, and compression springs. From the simulation results obtained the design data of the chopping shaft using steel material, dimensions Æ20mm/Æ16mm, and uniform load w= 0.24 N/mm. Analysis of maximum bending stress sB = 1.847 MPa, torsional stress t = = 0.103 MPa, and deflection fmax = 4.201 microm. The design of the spacer cutter component uses ABS material, dimensions Æ70mm/ Æ20mm with a thickness variation of 10-15 mm, and a compressive load of F= 100 N. Analysis of Von Mases Stress is 0.0319665 MPa and maximum displacement is 0.0000713021 mm. The design of the compressed spring components uses carbon steel, the wire dimensions are 2 mm, the inner diameter is 20 mm, and the length is 100 mm. The spring inspection analysis is positive.
