[ABSTRAK
Perkembangan bisnis dan martketing yang sangat cepat mendorong naiknya kebutuhan akan media telekomunikasi yang reliable, menarik, dan dinamis. Metode dalam penyebaran informasi yang populer digunakan saat ini adalah penyiaran. Dimana penggunaan spektrum frekuensi radio untuk keperluan penyiaran mengacu pada definisi layanan penyiaran pada peraturan radio ITU. Layanan penyiaran adalah suatu servis komunikasi radio dimana transmisinya ditujukan untuk penerimaan langsung oleh masyarakat umum. Penyiaran televisi lebih sering digunakan sebagai sarana penyebaran informasi dibandingkan dengan radio, karena dapat menyampaikan informasi secara jelas dengan suara dan gambar. Semakin luas daerah jangkauan siaran suatu stasiun TV, maka akan semakin banyak manfaat yang dapat dirasakan karena informasi dapat diterima dengan baik oleh masyarakat. Terdapat dua stasiun TV swasta di Bandung yang akan melakukan perluasan wilayah ke kota yang berdekatan, yaitu di kota Garut dan Sukabumi dengan menambahkan repeater baru serta menaikkan daya pancarnya. Kedua stasiun TV swasta di Bandung tersebut menempati kanal 42 dan 44. Kedua stasiun TV tersebut merupakan pemancar TV analog dan akan menggunakan kanal yang sama pada kota Garut dan Sukabumi. Kedua stasiun TV analog ini memiliki kanal bersebelahan dengan stasiun TV analog dan stasiun TV digital. Penambahan repeater baru dan menaikkan daya pancarnya dapat memungkinkan terjadinya interferensi kanal bersebelahan. Untuk mengatasi hal tersebut, maka dibuat sebuah aturan bahwa kuat medan penerimaan televisi siaran UHF pada lokasi titik pengujian atau pengukuran setiap wilayah layanan dibatasi paling besar 70 dBμV/m untuk band V. Skripsi ini bertujuan untuk menganalisis simulasi daya pancar untuk perluasan wilayah siaran TVdari Bandung ke Garut dan Sukabumi, dengan menentukan pola radiasi dan menaikan daya pancar repeater baru dengan batasan rasio proteksi agar daerah jangkauan dan populasi di kota Garut dan Sukabumi terlayani. Hasil dari simulasi diperoleh daya pancar pada kanal 42 dan 44 di kota Garut sebesar 42 dBW dengan antena 4-1 dan daya pancar pada kanal 42 dan 44 di kota Sukabumi sebesar 38,3 dBW dengan antena 730 372. Dengan penggunaan daya pada masing-masing pemancar tersebut telah memenuhi wilayah cakupan yang terlayani pada kota Garut dan Sukabumi dan pemancar yang digunakan tidak menginterferensi kanal yang bersebelahan. Namun terdapat beberapa wilayah yang tidak tercakup sinyal pancar karena kontur wilayah yang bergunung-gunung. Kata kunci : interferensi ABSTRACT
The rapid growth of various business and marketing leads to the needs of reliable, attractive, and dynamic telecommunication media. Broadcasting is one of the popular media which ever used in centuries. In the practical utilities, the broadcasting services use a particular radio spectrum frequency with respect to the ITU-T standard. The broadcasting services provide the essential informations which are directly served to the public user. Broadcasting is rather used to publicize the information than the radio due to its perceptibility through the sound and image repsentations. Consequently, the larger the coverage area of the broadcasting services the more advantages can be obtained because the informations can be delivered properly to the user. In this final project, there are two private television provider where both are located in Bandung. Theirs location are alongside cities which are Garut and Sukabumi. In order to broaden their coverage area, they increased the number of repeater and the level of power used by the transmitter respectively. Unfortunately, this method leads to an adjacent channel interference. In order to withstand this effect, policies are made to limit the usage of the bandwidth. For every service area the allocation is set to be at a maximum of 70 dBμV/m for V band. This final project is aimed to analyze the power used by the transmission to broaden the coverage area of the television services from Bandung to Garut and Sukabumi. The radiation patterns enhancement and the increase of transmitted power by the new repeaters are used. As a result, it is proved that for Garut and Sukabumi the 42 dBW and 38,3 dBW are appropriate with the use of the 4-1 and 730-372 antennas respectively in the 42nd and 44th channels. In the attained transmitted power, the adjacent channel interference can be evaded. In case of the extending the coverage area, there are still some particular areas which are delicate to overcome due to its geograhical contour which are mainly mountains.;The rapid growth of various business and marketing leads to the needs of reliable, attractive, and dynamic telecommunication media.
