Evaluation of DVB-T2 Digital TV Propagation Performance in the Bali Broadcast Area
The development of terrestrial television broadcasting technology in the world today is switching from analog broadcasting systems to digital broadcasting systems. Analog Switch Off (ASO) is the period when analog broadcasts are stopped and replaced with digital broadcasts. Through the jargon "Clean Picture, Clear Sound, Advanced Technology" people will feel better quality than analog TV. In the era of digital broadcasting, TV viewers not only watch broadcast programs but can also get additional facilities such as EPG (Electronic Program Guide) to find out the programs that have been and will be aired later. With digital broadcasting, there is the ability to provide interactive services where viewers can directly rate the sound of broadcast programs in addition to the presence of features that can be utilized, such as features related to disaster information. In this study, an evaluation of the performance of DVB-T2 Digital TV propaganda will be carried out in the Bali service area. The quality of digital TV broadcasts in the Bali broadcast area is influenced by signal propagation which is parameterized by parameters C / N (or S / N), Modulation Error Rate (MER), Bit Error Rate (BER) by measuring at the test point or location of the test point/test measurement which is the outermost limit of the service area under the Minister of Communication and Information no 23 / PER / M.KOMINFO / 11/2011. So this research can be produced a map of the quality of broadcasting services in Bali which can be used as an indicator to avoid Bali from blank spot areas that can be recommended for Digital TV operators in Bali for repeater installation planning

Analisis Performansi Penggunaan Link Loadbalancer Dan Link Failover Pada Internet Gateway
ABSTRAKSI: Saat ini internet sudah menjadi kebutuhan bagi setiap perusahaan terlebih lagi bagi perusahaan multinasional. Sedemikian pentingnya sehingga hampir sebagian besar perusahaan menggunakan dua link internet yang berbeda. Dengan konfigurasi satu link internet djadikan primary dan satu lagi dijadikan backup jika salah satu link down, dan juga dengan adanya dua link internet yang berbeda, ini memberikan suatu pilihan kepada para pengguna Internet untuk memilih salah satu dari link yang tersedia.Persoalan yang timbul dari kasus tersebut adalah masalah efisiensi biaya dan waktu. Efisiensi biaya dalam arti perusahaaan harus menyewa biaya link hanya untuk dijadikan back up, dan akan hanya digunakan apabila link primery down. Efisiensi waktu dalam arti jika link primery down maka user akan pindah ke link backup secara manual dengan cara mensetting ulang di computer tiap tiap user. Selain itu jika perusahaan ingin melakukan upgrade bandwith, maka perusahaan harus mengupgrade kedua bandwith baik link primery maupun link backup, karena jika hanya mengupgrade link primary saja dan apabila link tersebut down, maka link back up tidak akan mampu mengakomodasi semua user, dan user akan kecewa karena jaringan terasa sangat lambat.Untuk menyelesaikan semua persoalan yang timbul karena menggunakan dua link internet maka diperlukan adanya link load balancer yaitu kemampuan untuk membuat dua buah link berfungsi layaknya satu buah link atau dengan kata lain jaringan dengan akses lebih dari satu. Penggunaan load balancer mampu menggabungkan dua link seolah olah menjadi satu buah link dari sisi user. Selain adanya load balancer juga diperlukan adanya failover, yaitu proses pemindahan link yang aktif down ke link cadangan secara otomatis.Kata Kunci : Load Balancer, FailoverABSTRACT: Nowdays, each company especially the multinational company put the internet as a must. Almost of these companies uses internet services from two link internet. For the configuration one of link as primery and the other one set as backup for the down connection.the other benefit of using it is gve an option for the user to choose one of the two available connection.The problem that may appear from this case is cost and time efficiency. Cost efficiency have a correlation with the extra money that the company must spent to pay ou for the backup link internet. And the timeefficiency have a correlation with setting up from beginning for each each computer from each user mannualy if the conection down. Beside that in need to upgrade the internet service banwidth the company must do it for the both of the primery and the back up internet link. If the company just upgrade the primery one and the down conection problem happens, the user’s will be unsatisfied with the back up because it can not handle the conection from all of the user’s as good as the primary one.To solve al of the problem , the company need to use ink load balancer which can make the two of link internet can work as a single link internet. In the other world, the network have more thn one acces link. Load balancer have capability to building the two different link look like a single link in user’s side. The failover also need to use in automatically migration process from the active down internet link to the backup linkKeyword: Load Balancer, Failove
PERANCANGAN DAN ANALISIS PENEMPATAN BTS SISTEM LMDS UNTUK MENDAPATKAN CAKUPAN AREA YANG OPTIMAL DI DENPASAR BALI
ABSTRAKSI: Sistem LMDS (Local Multipoint Distribution Service) merupakan salah satu pendekatan teknologi wireless untuk menyediakan layanan broadband berbasis teknologi point to multipoint dengan frekuensi operasi antara 27 GHz hingga 31 GHz. Dengan cakupan sel yang tergolong kecil, dikarenakan besarnya pengaruh redaman hujan pada frekuensi tinggi, maka diperlukan adanya perencanaan penempatan BTS yang akurat dengan tujuan agar dapat diperoleh daerah cakupan yang optimal.Dengan bantuan mapinfo, ternyata jumlah sel yang didapat dari perhitungan tidak mampu mencakup semua area kota Denpasar Hal ini disebabkan oleh perhitungan yang tidak ideal dimana saat perhitungan tiap luas daerah dianggap berbentuk sederhana, sedangkan dalam kenyataannya adalah tidak. Penyebab lain adalah pemodelan sel yang dianggap hexagonal, padahal secara nyata areal cakupan dari suatu antena tidak uniform untuk tiap sisi.Dari hasil analisa didapatkan coverage area dari suatu sel berbanding terbalik dengan kepadatan sel. Artinya jika kepadatan pelanggan semakin bertambah, maka coverage area sel harus diperkecil sesuai dengan kapasitas sistem yang dipakai.Untuk mengoptimalkan posisi sel, maka dilakukan penggeseran sel sehingga dibentuk sel yang saling bersebelahan. Dengan metode ini diperoleh untuk daerah Denpasar membutuhkan 9 sel untuk daerah urban dan 2 sel untuk daerah suburban, serta C/I sebesar 26,44 dB yang masih diatas standar minimum LMDS yaitu 15 dB.Kata Kunci : ABSTRACT: LMDS System ( Local Multipoint Distribution Service) is representing one of technological approach of wireless to provide service broadband base on technology of point to point with frequency operate in range of 27 GHZ to 31 GHZ. With small coverage cell, because of rain influence in high frequency, so it is needed existence planning to locate BTS in order to the get an optimal coverage area.Constructively using mapinfo software, the amount of cell which is got from calculation unable to cover all area of Denpasar. It is caused by the calculation which is not ideal. The shape of area district assumed in simple model, on the other hand in real condition cannot. Other cause is cell model of hexagonal, though in real condition, the coverage of antenna is not uniform in each side.The analysis resulted that coverage area of cell is a fuction of cell density. Which mean if the number of customer grows, then the cell coverage area had to be made smaller adjust to the used system capacity.To optimalize cell position, a cell movement is made so a nbeighboring cell is formed, with this method , for Denpasar area 9 cell for urban and 2 cell for suburban is needed and a 26,44 dB of C/I which area still above a minimum of 15 dB LMDS standart.Keyword
