Abstract

This research motivated by the influence kind of substrate to the dimensions of the antenna, gain and impedance, to get the design of antenna with the characteristic consistent with the standards and need of the designer takes the right material. This research to prove the effect of microstrip substrate. The substrate according to the design (features) and desirable for a rectangular microstrip antenna 2,4 GHz. Method used is analisis from the result of the simulation using CST studio suite, the process follow some steps: (1) study literature (2) determining the types antenna (3) determining the specifications of the microstrip antenna (2,4 GHz frequentz of resonance, return loss <-9,54 dB direction) (5) calculating the dimention of the antenna based on the theory (4) simulation using CST studio suite (5) analyzing the result of simulation. From the research can be concluded that there is a value £r of the gain the rectangular microstrip antenna where the larger value £r and the gain will be smaller. There is an influence in the value £r foward the bandwidth to the square antenna microstrip. Which is the more larger the value £r bandwidth make the value smaller. There is an influence in the value £r foward beamwidth to the square antenna mictrostrip, which is the more larger that value of £r, beamwidth will be larger. To design the antenna with high value more than 90° 5dB that is use for the value of £r between 1-3. To design the antenna with the beamwidth that value more than 0,03 GHz that use for the material with value of £r between 1-3.Keywords : kinds of substrate, gain, banwidth, beamwidth, antenna microstrip, CST studio suite

Abstract

Information systems are the result of rapidly emerging technological developments because human needs as information users of technology are very strong and rapid. Begin with the very rapid growth of computer technology, computers such as smartphones, tablets, notebooks and others are limited in scale. This small computer device must be connected to the Internet so that it can be used properly. And the information system plays its role as a provider of information that computer users want to access when the computer device is linked to the Internet. The information system developed in this paper is the Citizen Data Collection Information System, this system was created using the YII Framework. The YII framework uses the MVC method which makes it easier to develop a Citizen Data Collection Information System. With this Information System, information about the latest condition of the residents can be easily accessed. So that the Kelurahan, Kecamatan, RW, and RT will have the latest information about their residents and easily anticipate if needed. In the development of this system, it has staged such as literature study, observation, interviews, analysis, design, testing, and implementation. The conclusion is that this information system can carry out the desired function when it is implemented.

Abstract

This research was conducted to find out the feasibility of using canva learning media in Basic Electrical and Electronics subjects in class X Cooling and Air Conditioning Engineering at SMK Negeri 3 Pariaman in the academic year 2018/2019. The research method used is the research development of the Instructional Development Institute. The research instrument used was a questionnaire. Respondents in the questionnaire were experts, teachers, and students. In canva learning media, the validity, reliability and practicality of the media are tested. Based on the results of validation by experts and teachers, the average value of validation is 0.83 which is at the validity value of ≥0.667, so it is in the valid category. In the media reliability test, the Cronbach's Alpha value was 0.731, so the criteria for media reliability were in high criteria. In the practicality test of the media by teachers and students, the average values were 90% and 86% respectively, so the practicality category of the media was in the very practical category. Based on the results of the three tests it can be seen that canva learning media is feasible to use in the learning processKeywords: Canva Learning Media, Media Validity, Media Reliability, Media Practicality.

Abstract

This research based by the weak received signal received by the Mobile Station (MS) caused loss propagation trajecktory  which allows the impending failure of calls and data connections. The purpose of this research is todiscover the impairment power received by MS. Monitored from the value of Rx Level and knowing the propagation model of Padang city urban areas in general.The method of measurement used is a Test Drive using TEMS Investigations software version 8.0. then analyzed with empirical models and models Okumura Hata, the results of the analysis compared with the standard value of Rx Level. This research was conducted in the morning and evening for five days.The analysis showed: (1) The signal quality measurements on base stations Terandam in average -81.6 dBm, and Hata model calculations on average -79.66 dBm, Okumura models average of -78.47 dBm, then the signal quality in good condition, BTS Simpang Haru is an average measurement of -82.7 dBm, and Hata model calculations on average -86.49 dBm, Okumura models average of -81.43 dBm, then the signal quality in good condition and the BTS Cendana Andalas in average measurement -80.03 dBm, and Hata model calculations on average -90.05 dBm, Okumura models average of -86.19 dBm, then the signal quality in a state of being. (2) Empirically propagation model for urban areas is a desert city in BTS Terandam Hata models, while BTS Simpang Haru and Sandalwood Andalas is a model Okumura. (3) Creep waves are blocked and then undergo reflection resulting trajectory taken further and further away, the received signal varies causing fluctuations in the signal and trigger fading, and failure in call and data. Keywords: MS, Rx Level, Drive Test, TEMS Investigation, transmitter, receiver and diffraction

Abstract

The development of Internet use has spurred Wireless Sensor Networks (WSNs) technology so that it becomes a widely researched and applied device. With the need to use high WSNs, the quality of features provided such as high data transfer speeds and the smallest possible disruption is something that should be available. Although some uses of WSNs do not require high speed and have a tolerance for interference, there are very few types of use. Nevertheless, routing protocols are provided to meet the types of data transfer requirements. The protocols available for each type will be analyzed and compared to find out the best performance.Keywords: data transfer, routing protocol, WSN.

Abstract

This research was conducted on the basis of the weakness of the received signal by service users (MS) caused by certain factors such as the geographical structure of a city, many buildings so that the path loss (Path Loss) resulted in data connection failure or call failure. This study serves to determine the comparison of Pathloss values in the Medium-Sized City and Large City Regions in Padang city with a 231-Hata cost propagation model. The measurement method used is the drive test using the Network cell Info LTE application and then analyzed with a model cost 231-Hata, the results of measurements with the RSRP standard research were carried out in the morning and evening for five days. The results showed: In Air Tawar BTS (Large City) by measurement and calculation of the Cost 231 Hata model, compared to the RSRP PT.XL Axiata Padang standard, the signal quality is medium category. While the Lubuk Buaya (Medium-Sized City) BTS is measured, and in the calculation of the Cost 231 Hata model. Compared to the RSRP PT.XL Axiata Padang standard, the signal quality is in Medium category. From the results of measurements and calculations there are differences in pathloss values that are not too significant. This is due to several factors such as building height, road width and geographical structure of the area.Keywords: RSRP, Pathloss, Drive Test, Cost 231 Hata,4G LTE
