The problem in this study is the low learning outcomes achieved by students on the subjects of Electronics Assembly Techniques which is below the minimum completeness criteria (KKM) set a school that is 75. This is presumably because they are learning is often used during the learning direct model is applied directly proven yet effective.The purpose of this research is to reveal how much influence the Demonstrasion learning model to study the results of class X TAV students on subjects Electronics Assembly Techniques (TPE).This research is an experimental study. The sample were students of class X TAV at SMKN5 Padang Academic Year 2014 / 2015.Class experiment is treated using Demonstrasion Learning Model and the control group is a class that uses the direct teaching model.The data is taken from the test results in the form of student practicum. Data were analyzed manually to test for normality, homogenity testing, and hypothesis testing. The research test result obtained value of average student which using model demonstrasion is 80,06 while student who use learning direct model lower is 71,60 with the percentage effect is 11,81%. The result of the calculation hypothesis at significance level α = 0.05 was found that t count> t table is 2,36>2,048. The results of these tests give an interpretation that H0 is rejected and H1 is accepted, this means that on average significantly experimental class learning outcomes greater than the average control class learning outcomes.

The purpose of this study is to know the difference between learning model of quantum teaching that combine with the technic record writing and structure and learning model of direct instruction in learning ouput on Menerapkan Dasar-Dasar Kelistrikan dan Elektronika for grade X TAV of SMK Negeri 5 Padang on odd semester, academic year 2013/2014. This type of research is true experimental. Participant were slected by non-probability sampling technique with purposive sampling. 30 students from Class XE3 TAV, which served as a controling class, used learning model of direct instruction. 30 students from Class XE1 TAV, which served as experimental class, used learning model of quantum teaching that combine with the technic record writing and structure. Data is collected from the final test then was analyzed for homogeneity testing, normality and hypothesis testing. The result indicates that experimental class has mean 78,7, while controlling class has mean 69,7. The result of hypothessis testing on significant level α = 0,05 is 4,887 > 2,042. Since the tcount is higher than the t table, then H0 is rejected and H1 is accepted. It can be inferred that learning model of quantum teaching that combine with the technic record writing and structure is better than learning model of direct instruction.

The result of hypothessis testing on significant level α=0,05 is 2,01 > 1,70 and the percentage effect 2.84 %. Since the tcount is higher than the t table, then Ho is rejected and Ha is accepted. It can be inferred that Contextual Teaching and Learning model is better than Cooperative model. Keywords: Contextual Teaching and Learning model, Cooperative model, Learning outcomes
The research was conducted by analyzing the optical fiber attenuation of the DWDM performance in terms of power received on optical fiber communication systems link Padang-Lubuk cone in PT. Telkom Padang. Optical fiber has a very small damping. Therefore optical fibers become the primary choice in telecommunications networks. To improve the transmission quality is better then the use of DWDM technology, DWDM technology is a method to insert a number of channels were transmitted in a single optical fiber. Instruments in this study is the Power Meter and OTDR JDSU MTS-2000 type, the type of cable used G.655 Single Mode type. Link Power Budget method is used to determine the performance of DWDM caused by attenuation based on the value of the received power output receiver. On the link Padang - Lubuk cone highest attenuation occurs in core 1 of 29.742dB with 100.035 km cable lengths, and the core 10 of 31.8 dB with 119.998 km cablelengths. Based on the large fault or attenuation/km core 1 of 0.297 dB/km, the core 10 of 0.265 dB/km and the standard ITU-T was 0.35 dB/km. Value attenuation/km core 1 and core 10 is still in normal conditions and under standard ITU-T 0.35 dB/km. Based on optical fiber attenuation, the results of analysis of the link power budget is the value of Rx is smaller than the value of Rx sensitivity of -27 dBm, it can be said performance DWDM optical fiber communication systems in normal and can be used to operate because the power output can still be accepted by receiver in the device. Keywords:optical fiber cable, optical fiber attenuation, DWDM, link power budget.
This research was motivated by a relatively small laptop power receives Wi-Fi signals, so it needs a directional antenna that has a high gain Yagi antenna like. This research is to: demonstrate the effect of spacing between elements to Yagi antenna gain, get the fixed spacing, knowing gain of Yagi antenna being tested and how much spacing between elements effect to gain enhancement statistically. This research use Gain Comparison Method. It is performed by CST Studio Suite simulation and measurements on 3 measurement points (TP), in a free barrier room, prevented plywood, and walled. Minimum and maximum of Spacing is 0,05λ and 0,35λ. The analysis showed: (1) Changes the spacing between elements of Yagi antenna using CST Studio Suite and the design of the AUT antenna proven effect on the gain. Changing the minimum space to maximum increase the gain untill the optimal space, then decreased. (2) The fixed spacing settings by optimal space. Space-1 optimal of simulation is 0,115λ; 0,205λ for space-2; 0,2λ for space-3, and 0,22λ for space-4. Space-1 optimal of Yagi AUT is 0,127λ, space-2 = 0,201λ, space-3 = 0,196λ, and space-4 = 0,22λ. (3) Simulastion result has gain 9,8 dB, Yagi AUT has 9,68 dB, and the commercial Yagi antenna by 14 elements has 11,84 dB. (4) The regression coefficient for space-1 (X1) is -58,534 <distance coefficient of signal source to TP (X2). Space-2 (X1) coefficients = -12,53 < X2 coefficient = -12,543. Space-3 (X1) coefficients = 0,72 > X2 coefficient = -1,289. Space-4 (X1) coefficients = 30,939 > X2 coefficient = -1,332.

This research is motivated by the problem of low learning outcomes in subjects apply the basics of electronics class X Audio Video Engineering Department (TAV) Vocational School (SMK) Bukittinggi School 1, an experimental study using two class is a class that acts as a control and experiment. This study aimed to see whether there is influence learning outcomes after implementing the learning model of Active Learning type Dynamic true or False. The problem in this study is the fact that the field is found in SMKN 1 Bukittinggi, there are many students of class X Audio Video Engineering who scored below the standart of learning outcome minimum completeness criteria in subjects applying the basic fundamentals of electronics set a school that is 75.The population of this research is class X TAV SMKN 1 Bukittinggi TA 2013/2014. The data collected from the test results of a study about the essay as many as 20 items. Data were analyzed using Microsoft Excel to test normality, test homogenity, and test hypothesis. Normality test all values obtained χ2count is smaller than the value χ2 table. Homogenitas test obtained χ2 count< χ2table , atau -1,03 < 14,067. Hypothesis test tcount> ttable yaitu (5,613 >1.697). From the test results of research obtained an average value of student which uses the learning model of Active Learning Type Dynamic true or False is 79,53 while the control group of student who use learning directly lower the 60,78. The results of the hypothesis by using Microsoft Excel in t count found that -1,03 < t table 14,067, so the alternative hypothesis (H1) is accepted or rejected the null hypothesis (H0). This means that on average significantly experimental class learning outcomes greater than the average of the control class learning outcomes. So it can be concluded that the application of Dynamic True or False effect on learning outcomes.Keywords : Active Learning, Dynamic True or False
