Abstract

This study aims to find a significant relationship with the classroom teacher's skills to manage learning outcomes Civics class VIII Semester Vocational TD Pardede Fodation Terrain TP 2013/2014 of 30 people with a total sampling. For variable data capture skills of teachers manage the class (X) researchers used questionnaires and to learn the outcome variable (Y) is taken from the list set value (DKN). Before the correlation test first tested for normality and linearity test as data analysis requirements. The results of the data analysis requirements of normality normal distribution classroom management skills with the formula X2hitung <X2tabel (6.093 <7.815. Based on the results obtained by analysis of the correlation coefficient was r = 0.571, by consulting the values obtained against rtabel value where value rtabel to a significant level 0, 05 the number of n = 30, ie 0,361. Since r count> r table = 0.571> 0.361 then it shows no relationship skills of teachers manage the classroom with student learning outcomes. to see if the relationship is significant, it used the t test. From the results obtained by t test t = 4.62 at the 0.05 significance level with the amount of N = 30 and obtained t table = 1.70. For t> t table = 4.62> 1.70 Then it can be stated that the hypothesis that there is a relationship which significantly between the skills of teachers manage the classroom with learning outcomes Civics Semester eighth grade students in vocational TD Pardede Fodation Medan TP 2013/2014, can be accepted.

Abstract

Generally the induction motor can be started by connecting the motor directly to the voltage source or by soft starting with regulator voltage to decrease the starting current. There are several methods of starting by regulating the input voltage with primary resistance starter or by autotransformer starter to avoid the higher current. The starting method is operating manually or magnetically. To have the starting electronically we need a power electronic apparatus which operate to regulate voltage.        The voltage regulator can be done by giving trigger signal using silicon control rectifier (SCR)
