Abstract

Vortex turbine is the one of turbines which meets those criteria. This turbine utilizes kinetic energy of vortex water and converts it into a shaft power. The objectives of this research were to obtain the torque that could be generated from the vortex  turbine by varying the width of turbine blades and to know  the output  power also the optimum efficiency obtained from this variation. This research was conducted by  using vortex pool in a laboratory scale with a diameter of 108 cm and 6 turbine blades on permanent rotation at 50 rpm, 60 rpm, and 70 rpm. Turbine blades were made from flat rectangular steel with a length of 40 cm sized 1/6, 2/6, 3/6, 4/6 and 5/6 times to radius of vortex pool.The results of the research showed the torque as 1.40 Nm at rotation is 50 rpm. The maximum power is obtained from blade with width of 3/6 times  radius of the pool, that is  8.60 Watts at head 0.362 m and discharge 11.83  l/s or  0.01183 m3/s at rotaion shaft is 70 rpm. This experiment also generated and turbine efficiency of 16.46% at rotation of shaft is 70 rpm.

Abstract

Aluminium-particulate glass matrices composites generally use the pressure in the making of green parts/green specimens before heating at sintering temperature.The purpose of this research is to develop the glass composites that it can be used as a material for indirect layer manufacturing, especially used for making plastic injection mold/insert mold. To achieve these goals, the flexural strength and dimensional errors were studied.Starting materials consist of the mixture of glass powders, aluminium powders, and acrylic powders in the volume ratio of 1 : 1 : 1. The glass powders and aluminium powders wererecovered from waste materials. The size of acrylics and glass particles was lower than 0.074 mm and aluminium particles size was lower than 0.297 mm respectively. Green specimens were made by using indirect layer manufacturing processes, while sintered specimens obtained by heating the green specimens in a furnace at a temperature of 700°C for 1 hour. Finished specimens were made by impregnation process of sintered specimens using epoxy resin.The bending strength of green specimens, sintered specimens, and finished specimens is 20 kg/cm2, 80 kg/cm2, and 170 kg/cm2 respectively. Maximum dimensional error of green specimens and sintered specimens is 50% and 40% respectively. Insert mold made by indirect layer manufacturing is broken after producing as many as 120 pieces of plastic products.Keywords: glass matrix composite, insert mold, dimensional error, bending strength.

Abstract

Replica is an imitation of an object in a size that is greatly reduced by the level of precision and detail that resembles the original object. One of the replica commonly made is a replica of transportation, especially buses, and one of the producers is Karang Taruna Dusun Bendungan, which is located in Karangmojo Subdistrict, Gunung Kidul District. Making replica so far has been done manually by relying on the cutter as a forming tool. In making manuals there are several obstacles faced, namely difficulties when making molds which include cowl molds, seat molds, AC cover molds and other parts. In addition, making miniature manually has disadvantages such as not being precise in shape and size with the original object and if there is a small change in a particular part, then it must be made from scratch again. Based on these constraints the team provided a solution by making a 3D printer machine that could be used to support bus replica production. Making a 3D printer machine with dimensions of 48 x 46 x 44 cm got a positive response.  In addition, the conducted training were enthusistically participated by the members. Utilization of 3D printer machines greatly helps the production process and increases the efficiency of time by 76% at the stage of making master prints.

Abstract

Mechanical properties problems that are closely related to the strength of 3D printed products generally occur during the development of 3D printing machines, In which several components used are the results of additive manufacturing technology. The damages generally occur in the components that receive force and the damage is in the form of cracks and fractures. The focus of this study is to determine the effects of increasing the value of fill density on mechanical properties, especially tensile strength and strain with carbon fiber filament material. This study used an experimental method using two types of filament material: nylon carbon fiber and PLA carbon fiber with a diameter of 1.75 mm for each filament and a recommended printing temperature of 190-260°C. Both types of filaments were printed using a direct extruder type 3D printing machine with a build size of 180 mm x 180 mm x 180 mm and printing was carried out at atmospheric pressure and a horizontal printing area. The Universal Testing Machine carried out mechanical properties testing implementation related to tensile strength and strain. Based on the results of experiments and tests that have been carried out, the strain values ​​are 16.970 – 26.681% and the tensile strength is 19.244 – 23.899 MPa for nylon carbon fiber filament material. Whereas the PLA carbon fiber filament material, the strain value is 7.673 – 15.546%, and the tensile strength is 18.580 – 24.552 MPa. Therefore, based on the test results, it is known that the fill density parameter value has an influence on the strain value and tensile strength so that it can be used as a reference in setting machining parameters.

Abstract

Casting is a manufacturing process that uses molten metal and molds to obtain a product that is closer to its final geometry. The quality of casting products is influenced by several factors and one of the important factors is the mold. The sand that is often used in making molds is resin coated sand, since this sand will bond to one another if it is heated. The research focus is determine the effects of grain size and heating temperature of resin coated sand on the mechanical properties of the mold which include compressive, shear and tensile strength. This study used an experimental method with large parameters of resin coated sand and heating temperature. From the test results, the highest compressive, shear and tensile strength values are Produced by sand with grain size less than 300 µm are identified.. The high heating temperature makes the bonds between the sands stronger and the strength value is higher..

Abstract

An excavator is heavy equipment with a hydraulic system as the main drive and along with its uses, many parties have developed it as a means of production and as a means of learning. The education world needs excavators as learning tools and practice media are currently constrained by price when commercial units are used. Therefore, a learning media that is more compact but does not abandon the main essence of learning is needed. This research aims to analyze the front attachment design of the Zhugimada mini excavator using the finite element method. The research was carried out using the ANSYS application for the static load simulation process and testing was carried out with a bucket containing sand weighing 25 kg and using three hydraulic cylinders. The simulation results show that the maximum von Mises stress value in the bucket component is 43.226 MPa and the maximum deformation is 0,51285 mm in the tooth bucket so in general the design of the Zhugimada mini excavator front attachment components can be declared safe and can be continued in the fabrication process.
