Published: January 2020

Abstract
Learning activities in PGRI Foundation schools, especially in SMA PGRI Kudus still use the conventional model that is directly face to face, so it is necessary to develop online learning media or what is now often referred to as e-learning to help teachers and students take material and do assignments by online. With online learning, teachers are expected to be able to update learning material and students can access it without constraints on place and time, besides assignments to students can be well controlled. In general, all PGRI Foundation schools in Kudus district have the same business process as well as the information system and technology requirements. But in reality, each school develops its architecture and information system separately. On the other hand, the majority of schools do not have enough budget to procure infrastructure to support the information systems needed specifically for learning activities such as e-learning. Cloud computing is often referred to as a new paradigm in the world of information technology related to resource efficiency. Cloud Computing has a service layer known as Software as a Service (SaaS). SaaS has several advantages and conveniences offered, including those related to resource efficiency and speed in developing an application. With SaaS, an application can be used at the same time by many tenants, with each tenant still being protected, so that application development costs can be further reduced. This research uses object-oriented system development methods with UML tools. This research aims to help schools in the Kudus Regency PGRI foundation improve the quality of learning by utilizing e-learning media without the need to think about the process of procurement, installation and configuration of hardware or software.

Published: January 2020

Abstract
In the manufacturing industry, computer numerical control (CNC) machine tool has been applied widely due to their high adaptability and precision in the machining of diversity shape, especially five-axis CNC machine tools. However, more error terms related to rotary axes, in which location errors are always considered as one of the most fundamental error sources, affect directly to machine tool performance. Thus, ensuring that a five-axis machine tool is machining within tolerance is a crucial demand in the market. This study investigates an efficient strategy using a specific 3D artifact to identify and characterize the location errors in rotary axes of a five-axis machine tool. The intended 3D artifact consists of a base plate, 2 standards ball with high roundness embedded on the top surface of the base. A Touch Trigger Probe will be utilized as the calibration instrument to capture the coordinate of 6 arbitrary contact points of the balls, then an optimization algorithm is applied to calculate the coordinate of the centers of the balls. By comparisons the relative position of the imaginary circles made of those centers with the ideal ones, all location errors will be measured individually.

Published: January 2020

Abstract
Metals have long been used to produce various musical instruments to date. Bonang Gamelan is one of the traditional musical instruments of Karawitan. Tin bronze was the primary choice because this alloy is capable of form and has excellent acoustic properties.
This study aims to compare the forging technique with post cast / PCHT heat treatment at a temperature of 550 °C with changes in microstructure and mechanical properties of Cu-20wt.% Sn and Cu-22wt.%Sn. Characterization of mechanical properties includes hardness/VHN, tensile strength σs), and bending (σb).
The forging and post-cast heat treatment/PCHT can improve the mechanical properties of hardness, tensile strength, and bending of the bonang gamelan product. The heat treatment process at 550 °C followed by holding time for 4 hours, followed by quench was able to produce grain growth and homogenization of the eutectic phase. The modulus of elasticity of the bonang gamelan specimen to the tensile strength was inversely proportional to the bending strength.

Published: January 2020

Abstract
Cu35Zn is a metal with a copper matrix that has the properties of forgings and has good corrosion resistance. Cu35Zn is commonly known as brass metal. Brass is widely used by industry to make various metal components. Brass for engine components must be able to withstand statistical and dynamic loads. One of these components is a ship propeller made of brass. These components must be able to withstand axial loads and have high corrosion resistance. To improve physical and mechanical properties, surface treatment needs to be done with the shot peening method. Shot peening is done with steel shot ball with a diameter of 0.5 mm with a hardness of 40-50 HRC. Shooting distance between nozzles and 100 mm specimens for 4, 6 and 8 minutes. The shot peening pressure varies 7, 8 and 9 bars. Corrosion tests according to the ASTM G5-94 standard are carried out in a 3.5% NaCl solution, instead of seawater. The results showed an increase in the best corrosion resistance of 0.028 mpy at 8 Bar shot pressure, which is 2.8 times compared to raw materials.

Abstract
The development of advanced technologies is related to the preparation and application of rare-earth metals. The tendency of development of rare-earth metal (REM) industry in Russia consists in tending to shed its dependence on the importation of REMs, to organize their production and products based on them in the required quantities, and to find new application fields for REMs. The aim of the present study is to elaborate the purification technologies of scandium and scandium hydride and to approbate its application as breakable additions to powder mixtures for the preparation of Nd-Fe-B permanent magnets. It is demonstrated the possibility to control the grains size of the 2-14-1 phase in Nd-Fe-B with the ScH∼2 addition. Moreover, our systematic studies are aimed at the development of corrosion-resistant Ag-free Pd-based REM-containing alloys with the high hydrogen permeability for the separation of high-purity hydrogen from hydrogen-containing mixtures. In the present study, the hydrogen permeability and mechanical properties of Pd-Sc thin foils prepared with special-purity scandium are discussed
Modification of contact surfaces of steel based materials in dry sliding under electric current of high density

Published: January 2020

Abstract
The purpose of the work was to study the interrelation of primary structure and wear resistance as well as to receive the initial ideas on contact features and surface layer deterioration in dry sliding against steel under electric current. The tribological behaviour of bearing steel and Hadfield steel (13% Mn) as well as the behaviour of composites on their bases was studied under electric current of high-density. Using X-ray phase analysis it was shown that the electrical current caused a modification of the surface layer of bearing steel and bearing steel sintered composite due to the formation of tribolayer and sliding surface melting in dry sliding against quenched AISI steel 1045. The formation of FeO in the tribolayer was observed also. This contributed to hardening of the sliding surface and to the realization of low wear intensity. Hadfield steel and a sintered composite based on it were capable of forming a tribolayer, where there was a low content of FeO on the sliding surface. This led to a high wear rate due to adhesion. The low thermal conductivity of Hadfield steel based materials should be considered as another reason for the rapid deterioration of their tribolayers.

Authors: Belenkov M E , Chernov V M 
Published: January 2020

Abstract
Three structural varieties of graphene layers consisting of pentagon and heptagon were calculated by the density functional theory method in the generalized gradient approximation. The sublimation energies of 5-7 polymorphs of graphene are 7.49, 7.51, and 7.28 eV/atom for T1, T2, and T3 layer types, respectively. The maximum sublimation energy and the highest stability are observed for the L5-7 T1 layer in which the deformation of the angles between the bonds in the structure as compared to hexagonal graphene is minimal. The conductive properties of layers 5-7 of graphene are metallic, since the band gap at the level of the Fermi energy is zero.
Comparison of two test methods for bending small disks on an annular support
Authors: Yu Goltsev V , Grigoriev E G , Osintsev A V , Plotnikov A S , Sedegov A S 
Published: January 2020

Abstract
Two methods of bending thin disks on an annular support are compared. The methods differ in the type of loading indenter and the equations that determine the strength of the material by the test results. The end surfaces of the indenter are flat cylindrical (indentor 1) or spherical (indentor 2). The methods were used to test identical disc samples from model materials: cast iron and graphite, as well as aluminum oxide samples obtained by spark-plasma sintering. The results of testing 24 disks of model materials and 10 disks of aluminum oxide on the ring support are presented. Bending diagrams of 12 disks of each model material on the annular support using two types of indentors indicate their different tensile strength. The calculated values of strength and their spread were higher when using indenter 2 than when using indenter 1. Thus, comparative tests have shown that the calculated strength of the tested materials depends on the nature of the failure of the samples and the type of bending diagram. The most reasonable were the test results obtained with the use of a flat-tipped indenter, which coincide with the characteristics of the strength of materials and the minimum spread of values.
