Spatial pattern of propagation digital terrestrial television system in east jakarta city

Development of television has gone into terrestrial digital systems that have many advantages over previous (analogue) systems. The nature of radio waves for digital terrestrial television broadcasting that propagates or propagation causes reflection and diffraction due to disturbances or barriers in the form of tall buildings and trees. The purpose of this research is to analyze propagation patterns of digital terrestrial television systems and the effect of physical conditions on the propagation value of digital terrestrial television systems. The variable is land cover, relief, slope direction, distance from transmitter, height, and building height barrier. The method uses spatial analysis within grid analysis and correlation analysis. The results of this study showed that the propagation pattern of digital terrestrial television systems spread randomly to the moderate signal in the central and northeast of East Jakarta city and clustered for a bad signal in the north and northwest areas of East Jakarta city and good signal in the southern region of East Jakarta city. Based on correlation analysis, the propagation pattern of digital terrestrial television systems influenced by the physical condition of the region from variable height and height barriers of buildings.
