Development of technology shown rapid progress in various of structural applications especially on advanced of component in industry. Using of aluminum as a matrix on composite fabrication by addition ceramic as reinforcement is the better solution, for expected to improve the mechanical properties on materials-based composites. The process carried out was combining SiC particles with an aluminum (AA1100) as a matrix with variations number of rolling cycle’s: 2, 4 and 6 as direction. Preparation of SiC particles with transverse, cross section and mix variations through a hot working process with the technology of severe plastic deformation (SPD) using the method of repetitive press roll forming (RPRF). The results obtained was mechanical properties increased when the roll cycles high with mix of variations in the direction of SiC arrangement resulting in a wider distribution of SiC into the matrix AA1100. Rolled process by cycle 6 and the direction of the SiC mix resulted in higher hardness of 55.54 HV, tensile strength was 90.46 MPa, porosity 0.33% density 1.831 gr/cm 3 and SiC distribution 23.19%. Increasing the number of rolling cycles, the thickness of the interface for the formed layer and the size of SiC particles will decrease due to SiC particles scattered in most aluminum matrices, which can increase the hardness value.

In this modern era all human activities are still very dependent on non-renewable energy sources. Electricity is one of the most important needs for humans, starting from lighting, communication, transportation and other needs. Energy supplies, especially fossil energy, are increasingly depleted, therefore an alternative energy source that is environmentally friendly and abundant availability is needed. One alternative energy source is water energy, especially energy derived from Piko Hydro. With variations in valve openings installed on pelton turbines of 18ᵒ, 36ᵒ, 54ᵒ, 72ᵒ, and 90ᵒ analyzed using the experimental method to determine the efficiency of the pelton turbine system used to produce electrical power from the Piko Hydro system. The results of this study indicate that the highest power is produced with a 90ᵒ faucet opening where the Power is 3.96 Watts and the system efficiency is 14.56%.

The 2013 curriculum uses a classroom-based assessment. The curriculum contains various supporters, one of which is an assessment. Assessment by teachers is used to measure the achievement of learning objectives. But in the real world, a teacher has difficulty in developing assessment planning, assessment implementation, and processing of assessment result, and teacher has not analyzed comprehensively about validity and reliability in question, and analysis of evaluation instrument conducted by the teacher is only limited to analyze difficulty level. Thus, the problem that is made to know the cognitive level of students has not known the quality. The objectives of this study were (1) to know the reliability of cognitive assessment instruments developed, (2) to know the level of difficulty, (3) to know the differentiating power, and (4) to know the effectiveness of the cultivators. The method used in this research is research and development (R & D) developed by Borg & Gall. Data analysis technique that is done is instrument validation test with construct validity through judgment expert, reliability test using ITEMAN with formula CR-20. This study resulted in (1) the reliability of the question items of 0.740, (2) the degree of difficulty there are three levels, namely difficult 23%, medium 70%, and easy 7%, (3) distinguishing power on the grain matter analysis resulted in 20%, 7% of the questions are sufficient, 60% is good, and 13% are very good, and (4) the effectiveness of the deception is 82% working and 18% not working.

A ffecting factor of importance in industrial applications of Powder Metallurgy is a process of consolidation , t he fabrication process with the good parameters by increasing of the bond strength o n the surface to reduce the number of pores. In particular, methods of Severe Plastic Deformation (SPD) overcoming a number of difficulties associated with residual porosity in the sample which solidified. Ultrafine–Grained (UFG) materials processed by ECAP usually show unique mechanical properties such as; high yield stress at low strain hardening, good ductility on low temperatures and high strain-rate super-plasticity at high temperatures. Production of Al alloy growing rapidly, particularly in the automotive industry . Although high-strength aluminium alloys containing Mg and Si (6xxx series aluminium alloys) which are easily reached, for formability processes is not sufficient to be applied. Therefore, much research has focused on increasing the formability of these alloys through heat treatment. High strength aluminium alloy, such as alloy AA7XXX, which combines the power of high-density ratio with excellent mechanical properties, is widely used for aviation applications, superplastic forming into the high-volume fabrication of components in the automotive. Consumer products industry is currently limited because of the relatively low strain rate. AA6XXX are some of the alloys materials, mostly used currently covering the whole range of industry. Applications of AA6XXX easier to process than AA7XXX because of properties the material elasticity, AA7XXX tend to form internal cracks as a result of microsegregation. That way heat treatment is required to improve the properties of the material when it is processed by ECAP.

A gasoline motor engine using electronic control system has several sensors and actuators driven by a computer. This paper aims to reveal the role of an engine temperature sensor mounted on a gasoline engine motor. The test ing data shows that there is a co nnectivity between the temperature data obtained from the cool ant temperature sensor with the fuel injection time and the exhaust gas emission content.

As a lightweight metal with mechanical properties similar to natural bone, magnesium-based material has been gaining wide popularity. However, the applications are seriously limited due to the excessively rapid degradation rate in the physiological environment, causing the magnesium to degrade faster than the complete rehabilitation of the bone itself. Grain refinement approach is currently the selected approach to obtain a lower degradation rate without adding other element that might be harmful to human body. This paper studies the possibility of reducing biodegradation rate of a biodegradable through reviewing various studies on grain refinement through hot deformation and rapid solidification.
