"ABSTRAKJaringan Mobile Internet Protocol adalah feature yang terdapat pada Ipv4 dan Ipv6 dan memungkinkan mobile device untuk dapat diidentifikasikan dengan menggunakan IP tunggal walaupun device tersebut berpindah dari satu jaringan (home network) ke jaringan lainnya (foreign network). Proses perpindahan tersebut dinamakan handover yang dibedakan menjadi horizontal dan vertical handover. Untuk mengetahui performa jaringan dengan kedua jenis handover tersebut, dapat diukur beberapa parameter QoS seperti throughput, delay, packet loss dan transfer time. Skripsi ini menggunakan aplikasi game flash yang akan diukur QoSnya. Pengukuran dilakukan dengan cara memainkan aplikasi antara server dan client. Dari hasil pengukuran QoS, dapat dilihat bahwa proses horizontal handover memiliki performa yang lebih baik dibandingkan proses vertical handover. Selisih performa skenario vertical handover dengan horizontal handover untuk parameter throughput, delay, packet loss, dan transfer time adalah 21,61%, 18,43%,20% dan 23,48%.

AbstractMobile Internet Protocol is a network feature contained in the IPv4 and IPv6 and enable mobile devices to be identified by using a single IP even though the device is moved from one network (home network) to another network (foreign network). Transfer process is called handover is divided into horizontal and vertical handover. To find out the network performance with both types of handover, the QoS can be measured several parameters such as throughput, delay, packet loss and transfer time. This thesis uses flash game application to be measured QoSnya. Measurements were performed by means play between server and client applications. Of QoS measurement results can be seen that the horizontal handover has better performance than the vertical handover process. Difference in the performance of vertical handover scenarios with horizontal handover to the parameters throughput, delay, packet loss, and transfer time is 21.61%, 18.43%, 20% and 23.48%."

"Material quarternair CuGaSeTe and CuGa0.5In 0.5Te2 merupakan material dasar yang digunakan dalam fabrikasi solar sel. Material tersebut memiliki koefisien absorpsi yang tinggi sekitar 103 ? 105 cm-1 dan rentang energi gap 1-5 eV. Pada penelitian ini telah dibuat lapisan tipis dengan menggunakan metode evaporasi Flash dari butiran-butiran quarternair material CuGaSeTe and CuGa0.5In 0.5Te2 yang dievaporasi agar menempel di substrat kaca. Setelah lapisan tipis diperoleh kemudian dilakukan karakteristik optik dan listrik lapisan tipis tersebut. Spektroskopi X-Ray Diffraction (XRD) digunakan untuk memperoleh parameter kisi dan struktur kristal lapisan tipis tersebut. Hasil XRD memperlihatkan bahwa struktur lapisan tipis CuGaSeTe and CuGa0.5In 0.5Te2 adalah chalcopyrite. Koefisien absorpsi dan energi gap lapisan tipis dihitung dari pola kurva transmitansi dan reflektansi hasil pengukuran difraktrometer UVVIS. Dengan menggunakan Energy Dispersive Spectroscopy (EDS), komposisi lapisan tipis dapat diketahui, sedangkan dengan menggunakan Hall Effect dapat dihitung resistivitas, mobilitas dan pembawa muatan mayoritas lapisan tipis CuGaSeTe and CuGa0.5In 0.5Te2.

Quarternair CuGaSeTe and CuGa0.5In 0.5Te2 Thin Films Fabrication Using Flash Evaporation. Quarternair materials CuGaSeTe and CuGa0.5In 0.5Te2 are the basic materials to solar cell fabrication. These materials have high absorption coefficients around 103 ? 105 cm-1 and band gap energy in the range of 1-5 eV. In this research, the films were made by flash evaporation method using quarternair powder materials of CuGaSeTe and CuGa0.5In 0.5Te2 to adhere in a glass substrate. After the films were obtained, the properties of these films will be characterized optically and electrically. The lattice parameter of the films and the crystalline film structure were obtained using X-Ray Diffraction (XRD) spectroscopy. The XRD results show that the quarternair CuGaSeTe and CuGa0.5In 0.5Te2 films have a chalcopyrite structure. The absorption coefficient and the band gap energy of the films were calculated using transmittance and reflectance patterns that measured using UV-VIS Difractometer. The films composition can be detected by using the Energy Dispersive Spectroscopy (EDS), while the films resistivity, mobility and the majority carrier of the films were obtained from Hall Effect experiments."
