Rancang Bangun Antena Dipol Magnetik Kupu-Kolinier-Tiga Elemen Omni Direksional Pada Frekuensi 1900 MHz-2500 MHz
ABSTRAKSI: - -Kata Kunci : -ABSTRACT: Three elements-collinear-butterfly magnetic dipole antennas is wide band antenna. This is consisting of three elements butterfly magnetic dipole that made from copper. By using Babbinet-Booker principle, the dimensions of each element are established. Each element is connected to coaxial then that arrange collinear vertical by using pralon pipe. This antenna is designed using the ferrite ring balun to make the transition between antenna impedance and coaxial impedance smoothly. In this final project had been realized three elements-collinear-butterfly magnetic dipole which have first specification; bandwidth reach up to 600MHz (27,3%) with range 1900MHz up to 2500MHz with limited VSWR �� 1,5. It has omni directional radiation pattern, linear-horizontal polarization, terminal impedance 50 ��, and gain �� 6,2dBi. All the specifications will be tested and analyzed. On the last phase of design and realization magnetic dipole, measurement test phase had found that are close to the first specifications. In realizing this antenna had found bandwidth equal to 1005,02 MHz (45, 32%) with range frequency 1715 MHz up to 2720, 02MHz with limited VSWR �� 1,5. This antenna have omni directional radiation pattern, ellipse polarization, and gain 10,26 dBi at 1900 MHz, 11,12 dBi at 2200 MHz, 12,443 dBi at 2500 MHz.Keyword:
STRATEGI PERENCANAAN PEMBANGUNAN DALAM MENGEMBANGKAN POTENSI EKONOMI KOTA PEMATANGSIANTAR PROVINSI SUMATERA UTARA
This study aims to look at planning strategies in developing economic potential in Pematangsiantar City, which is in the middle of North Sumatra Province and is the second largest city after Medan City with a distance of more than 128 Km. The entire administrative area is directly surrounded by the administrative area of Simalungun Regency. To review a necessary development plan, a strategy is needed to develop the potential as a source of regional income. The potential that is located in Pematangsiantar City is more conducive to its trade potential. This is due to the adjacent location and as a crossing route to the National Strategic Area (KSN) of Lake Toba, which acts as a supporter in tourism activities. As a city that may be on trade, Pematangsiantar has various historical beauties to visit. However, the main problem that occurs in the potential that exis in Pematangsiantar City consists of many residents living and the lack of natural resources that are utilized in managing their potential resources. a direct knowledge to find out some of the economic potential developed in creating a stable economy in this new normal. Thus we need a research method that uses qualitative and quantitative research, where this research conducts direct interviews from the relevant sources and conducts field observations and also through references that have been carried out by previous research. The results of the research and discussion carried out were obtained from observations from various relevant sources that showed a significant influence between the strategy of its economic potential and the development of its development planning to be stable. Based on several summary tables, it is known that it affects the population and the rate of growth of development infrastructure in Pematangsiantar City. In the end, entering the new normal requires a planning strategy to achieve stable and prosperous developmen
