Abstract

At present the need for higher internet connection along with the age which is growing so fast. Then there is the latest breakthrough in telecomunications that is WiMAX technology is a wireless broadband technology reffered the IEEE 802.16 standard. WiMAX technology comes with a network of excellence in aspects of data access speed, wide area coverage and the presence of QoS is can allocate frequencies in accordance with user needs using OFDM technology. WiMAX technology can reach area far as 50 kilometers, also allows user equipment (customer premise equipment or CPE) to get a broadband connection without having a direct path (non line of sight, NLOS) to the base station (BS) and provides a total data rate of up to 75 Mbps. Results of this Final project assumed that the area where will be design is Banyumas district. Then final project results of the PRX -100.31 dB; the Total Margin of 23.56 dB; Path los of 134.5 dB; gamma (?) of 4.375; Frequency correction factor (?PLf) of 0,36; antenna correction factor (?PLh) is -3,25; Radius Cells (d) is approximately 1995 meters; area of cell is at 10,34010495 km2 and the number of cells 133

Abstract

Port paralel tentunya sudah tidak asing lagi dalam dunia komputer. Hal tersebut disebabkan karena port paralel merupakan sarana komunikasi yang terdapat pada Personal Computer (PC). Dengan memanfaatkan port tersebut, saat ini komputer juga dapat dipergunakan untuk keperluan pengontrolan/pengendalian rangkaian listrik dengan memanfaatkan port paralel (port printer). Port paralel memiliki kecepatan transfer data yang lebih cepat apabila dibandingkan dengan port serial, maka dari itu port paralel lebih banyak dipergunakan untuk pengendalian nyala lampu (LED). Dengan memanfaatkan bantuan software Saraf Listrik versi 1.01, maka port paralel dapat menjadi alternatif baru untuk pengendalian traffic light.

Abstract

Seiring dengan semakin luasnya penggunaan XML pada berbagai layanan di internet, yang penyebaran informasinya sebagian besar menggunakan infrastruktur jaringan umum, maka mulai muncul permasalahan mengenai kebutuhan akan keamanan data bagi informasi yang terkandung didalam sebuah dokumen XML. Salah satu caranya adalah dengan menggunakan teknologi XML Enc. Pada makalah ini akan dibahas mengenai cara menggunakan XML Enc menggunakan bahasa pemrograman java, khususnya menyandikan dokumen XML (enkripsi), dengan algoritma AES dan Tripple DES untuk menyandikan dokumen XML menggunakan kunci simetrik.

Abstract

Router very important for computer network. To get the router can buy a router products but can also design your own using personal computers. Mikrotik is one of the router manufacturer that provides products in the form of hardware or software. If you want to pay less to design a router can use operating system Ubuntu. This operating system is open source and provided free of charge by the manufacturer. If you want to design a router with this OS can make use of personal computers are often used in homes or offices. Merging the performance of both types of routers can also be usedto cover the lack of one another. With the proxy on a local network then the use of bandwidth can be saved. Becausethere are several websites cached and stored therein if the same website is accessed by other users, the router transmits only from the proxy to the computerwhich make the request.

Abstract

A high necesarry data service and bigger network capacity becomes a critical issue in the GSM network. One of the good and bad size parameter reference-quality GSM network can be viewed on the performance parameters MLSLOT Allocation Blocking. The default value for parameter MLSLOT Allocation Blocking are ? 40 % that the network is otherwise well. To overcome these problems it is applied to UMTS technology. The study was conducted to determine how the performance of the 2G PT Indosat Tbk. Before and after the application of technology and how it compares to the performance of UMTS cellular network PT Indosat Tbk. before and after implementation of a UMTS network. In conducting this study the authors to collect the necessary data and did the interview if the supervisor does not know From the research the average value MLSlot Bocking Allocation has decreased, for the first sector decreased on average uplink 0.70% to 0.17% down 0.53%.The average downlink 26.49% to 14.98% down 11.51%. Sector 2 uplink average 0.24% to 0.00% down 0.24%, the average downlink 5.16% to 0.04% down 5.12%, Sector 3 uplink average 0.6% to 0.21% down 0.39%, the average downlink 23.99% to14.98% down 9.01%.

Abstract

Penitipan kendaraan Terminal Purwokerto menggunakan cara administrasi manual. Program sstem informasi penitipan motor ini dibuat dalam rangka usaha komputerisasi data perparkiran di Terminal Purwokerto. Perancangan sistem informasi penitipan ini metode yang digunakan yaitu menggunakan metode waterfall. Pembuatan sistem informasi penitipan ini menghasilkan 3 user leveling yaitu operator, atasan dan pengguna parkir. Tabel yang dihasilkan sebanyak 3 tabel. Program sistem informasi penitipan ini menggunakan penyimpanan MySQL sebagai database server karena mampu menerima dan mengirimkan data dengan cepat serta dapat menyimpan data penitipan dalam jumlah yang banyak. Pengujian program sistem informasi penitipan ini dimulai dari tahap pengujian sistem, pengujian interface, proses upload ke web hosting dan melakukan pengujian jaringan. Diharapkan sistem informasi penitipan ini dapat dikembangkan dalam segi keamanan dan kelengkapan datanya, tambahan fasilitas backup database dan lebih bagus lagi jika ada penambahan RFID dalam proses output dan input data parkir di penitipan.
