Abstract

Humans do regular physical activities such as running. Gait is forward  propulsion of the human body using lower extremities as a thrust. Humans gait pattern is characterized by their limbs movement in terms of velocity, ground reaction force, work, kinetic energy and potential energy cycle . Human gait analysis is used to assess, to plan, and to deliver the treatment for individuals based on the conditions that affect their ability to move. Gait analysis is commonly used in running sport to improve the efficiency of athletes in running and to identify problems related to their posture or movement. The aim of this research is to do running gait analysis study of human, using force plate which equipped by track board. The benefit of this study is to provide information, ideas and new perspectives about running and its prevention over an injury. The main method that will be discussed in this study is system design of gait analysis with specific setting, hardware and software, in order to acquire data(s).

Abstract

Electrical impedance value analysis on frozen tilapia flesh aims to analyze non-destructive method of electrical impedance to distinguish between fresh and frozen tilapia flesh. The measurements were carried out to measure electrical impedance fresh tilapia flesh and frozen tilapia flesh for 1-5 days at 10 Hz - 200 kHz frequency using needle electrode. The result shows that the impedance value characteristics of the fresh tilapia flesh is higher than frozen tilapia flesh. The longer strored in the freezer is directly reversed with the value of electrical impedance. The observation of electrical impedance on quality of tilapia flesh preferable observed at a frequency of 1 kHz - 100 kHz.

Abstract

 Senditized Dye Solar Cells (DSSC) consist of photoelectrode, dye, electrolyte and counter electrode which is one of the photochemical electric cells. In this article will discuss the influence of the thickness of the electrode on the electrical properties. Electrodes made by screen printing method. Screen by type T-49. TiO2 deposited on the FTO variation of the number of layers to obtain a thickness of 1, 2, 3 and 4. DSSC tested thickness by Screen Electron Microscopy (SEM), absorbance test by UV Visible Lambda 25 and characterization of current and voltage test by Keithley Measurenment 2602A. The test results showed the thickness of the TiO2 electrode thickness (1.5 ± 0.2) μm, (2.9 ± 0.5) μm, (3.5 ± 0.6) μm, and (4.5 ± 0.8 ) μm. Based on the test results absorbance maximum value contained in thickness (4.5 ± 0.8) μm having a dye adsorbed at most and have the highest efficiency  2.41%.

Abstract

The image of subsurface with a migration method keeps on developing to get an image result which the closest in real condition. The conditions in subsurface are very complex and variables it couses the process of wave  propagation which can not be judged as the same in every layers. so it is needed an anisotropy pharameter analysiz (η) in seismic data migration process. The research will compare two kinds of migrations those are Kirchhoff migration and finite difference anisotropy. It is done because not all datas are processed by anisotropy, even with isotropi it will get good result. The result of kirchoff migration has not so good quality (low resolution) on the first layer reflector.but on the second and third layer reflector have good result (high resolution). I estimate that in the first layer reflector there is anistropi influence, because the ratio effect between far offset and the depth is hight. The analysis result get η ansotropi pharameter result as 0,25 and put into migration process. On the second migration process is finite difference anisotropy appears on the first layer reflector and shows high resolution and suitable with the real layer model.
