Abstract

Signal is a wave that can be expressed by physical phenomenon. Mathematically signal wave can be represented as a function of single or many independent variables, for example signal wave over hill or mountain as a function of distance or time. In fact, signal spreading as a wave have many attenuation, for example is caused by difraction  when the signal over hill or building. The purpose of this writing scientific jurnal is to make a model of knife edge difraction, that seen by two cases, such as transmitter has same height to receiver and transmitter has different height to receiver. Computation result show that transmitter has same height to receiver then the increasing of value of v cause reduction of difraction variable. And  in case of the height transmitter and receiver is not the same, the degradation of v variable has an effect to the increasing of difraction variable.

Abstract

The purpose of this study was to determine the direct and indirect effects of formal education and salary variables on time looking for jobs with competence as the intervening variable. This study uses prime data in the form of questionnaires which are distributed to fresh graduate students who have gotten jobs. This study used the intervening regression method with R Studio software to process the data. The research results formal education cannot directly affect the competence of fresh graduate students and can indirectly influence formal education through competence on time looking for jobs. Meanwhile, salary can affect competence directly and have an indirect effect between salary through competence on time looking for fresh graduate student jobs.
