This study aims to describe the results of characterization of physical properties and design comparation of knee implant. the characterization of the material was intended to determine the morphology using SEM, crystal structure using XRD, and chemical composition using XRF. In both designs, the simulation was carried out to get the total deformation value. Simulation is carried out by loading humans walking, jumping, and downstairs in 0-1.1 seconds. While the comparation was focused on comparizing the total deformation value from the human activity of walking, jumping, and downstairs to determine the optimum design. The finding of this study were SEM showed that many parallel strokes on Ti6Al4V, then XRD test showed that the crystallinity peak was at position 40.5189˚ which were indicated by the crystal orientation index [200] reaching 29.35 counts (cts), and Full Width Half Maximum (FWHM) at an angle of 0.288˚ which had an atomic distance along the length of 2.2246 (Å ) with a relative intensity of 100%. And the XRF test showed the highest chemical content of Ti6Al4V was Ti, amounting to 85.12%. This was indicated by the total maximal deformation of the first design 0.23030 micormeter while the second design was 2.109600 micrometer, so the first design was more recommended for implant use. While comparation of total deformation showed that the first design had the lowest maximum average deformation value. The results showed that the first implant design was the optimum design.

The purpose of the study was to investigate the effects of dolomite body, frit and potassium feldspar on the properties of color slip for decorative method of color slip on earthen ware production. The characterization of raw material was analyzed by X-ray fluorescence (XRF). The experiment started with triaxial blend of dolomite body, frit and potassium feldspar in the defined ratio and then to painting of color slips on earthenware production. After that, firing specimens at 950 °C in oxidation atmosphere. Finally, the specimens were tested microstructure and physical properties. The results showed that the ratio of 50% dolomite body, 40% frit and 10% potassium feldspar were optimum properties for decorative on earthenware body. In color slip consisting of blue color added Cobalt oxide 1% ,Green colors added chromic oxide 10% , Gray color added manganese oxide 10% ,yellow color added stain 2225 10% and hazel color added ferric oxide 2 wt %.

En este trabajo se propone una metodología sencilla y de aplicación práctica en campo para la determinación aproximada de la Resistencia a la Compresión Simple (RCS) en rocas, propiedad o característica que es importante en minería, ya que mediante la misma, se ejecutan análisis para la valoración de factores de seguridad y estabilidad y/o posibles sistemas de fortificación en las obras o estructuras mineras, a más de que la caracterización de la RCS es también influyente en el uso de explosivos para la explotación o extracción de materiales de una cantera o mina. Esta estimación se la propone en base a la determinación de las siguientes tres propiedades de la roca, que en esta investigación las denominamos densidad, porosidad y absorción “en mina”. Estas propiedades físicas se las puede obtener de una forma simple, pero metódica y en este trabajo se han ejecutado ensayos sobre un mismo material o roca proveniente de la zona de Cojitambo, provincia del Cañar (Ecuador) y sobre una base de 60 muestras o probetas. Los resultados obtenidos permiten una correlación entre las propiedades antes descritas y la RCS, a más que se ha estructurado una metodología de cálculo para el objetivo planteado.   This work proposes a simple methodology and practical application in the field for the approximate determination of the Unconfined Compressive Strength (UCS) in rocks, property or characteristic that is important in mining, since through it analyzes are carried out to the assessment of security and stability factors and/or possible fortification systems in the works or mining structures, in addition to the characterization of the UCS is also influential in the use of explosives for the exploitation or extraction of materials from a quarry or mine. This estimate is proposed based on the determination of the following three properties of the rock, which in this investigation we call density, porosity and absorption “in mine”. These physical properties can be obtained in a simple, but methodical way and in this work, tests have been carried out on the same material or rock from the Cojitambo area, Cañar province (Ecuador) and on the basis of 60 samples or test tubes. The results obtained allow a correlation between the properties described above and the UCS, in addition to a calculation methodology for the proposed objective.
