Judul: Pengaruh Multi-streaming dan Congestion Window pada SCTP terhadap Kinerja Mobile Ad Hoc Network (MANET)
Abstrak: Stream Control Transmission Protocol (SCTP) is a connection-oriented transport layer protocol that provides reliable data transfer service an Internet Protocol (IP) network. The two main features of SCTP are multi-streaming and multi-homing. Multi-streaming allows multiple streams to send data; if one stream fails, only part of the data is lost and needs to be resent. Multi-homing is a feature that allows multiple IP addresses at one endpoint to ensure that failures do not bring the transmission to a total halt. This research was performed using Network Simulator (NS-2) to analyze multi-streaming and congestion window effect in Mobile Ad Hoc Network (MANET). Mobile ad hoc networks were formed dynamically by an autonomous system of mobile nodes that were connected via wireless links in absensce of network infrastructure or centralized administration. The metrics which evaluated in this simulation were throughput, delay, and packet loss ratio. As a result, delay value is reduced only when the addition of congestion window up to 2 * MTU. Increasing the above 2 * MTU will actually add value to the delay. SCTP quality was good enough for delay-sensitive application, because the delay was less than 4 seconds.

Judul: Analisis Pengaruh Kecepatan Mobilitas Terhadap Kinerja Video Streaming pada Jaringan Wireless Ad Hoc
Abstrak: Wireless technology has become a lifestyle in many countries. Though wireless networks provide more flexibility than wired networks, it has lower reliability and data transfer speed than wired networks. The development of streaming technology is analogous with the quality of the streaming services. Streaming technology becomes increasingly important with the growth of the internet because most users do not have fast enough connection to download large multimedia files quickly. This research presents calculations of data from experiments of video streaming performances in wireless ad hoc networks with bit rate format of video 256 Kbps, 512 Kbps, and 768 Kbps. Data captured from the experiments is divided into four scenarios: client performs mobility and client does not perform mobility, with one client perform video streaming and two clients perform video streaming concurrently. Client’s mobility speed is limited only by walking speed, which are 0.6 m/s, 1.2 m/s and 1.6 m/s. The video quality calculations are based on the Quality of Service (QoS) of video streaming, which include packet loss, throughput, delta and jitter.

Judul: Preparasi Imunoglobulin Yolk (Igy) Spesifik Rabies Untuk Pengembangan Kit Diagnostik
Abstrak: Rabies adalah penyakit yang disebabkan oleh virus neurotropik genus Lyssavirus famili Rhabdoviridae dan dapat ditularkan dari hewan ke hewan lain maupun hewan ke manusia melalui saliva.Penyakit ini bersifat zoonosis dan berakibat fatal pada manusia, sehingga semua material yang dicurigai terinfeksi virus rabies harus ditangani dengan memperhatikan aspek keamanan sesuai dengan spesifikasi World Health Organization(WHO). Diagnosis penyakit rabies di Indonesia selama ini hanya berdasarkan gejala klinis dan pemeriksaan histopatologis preparat otak yang berasal dari hewan tersangka.Teknik diagnosa untuk mendeteksi virus rabies harus terus dikembangkan. Antigen dan antibodi standar sangat diperlukan untuk diagnosa rabies. Penelitian ini bertujuan untuk memproduksi antibodi standar terhadap virus rabies yang nantinya dapat di gunakan sebagai antibodi standar dan membandingkan dua metode purifikasi imunoglobulin yolk(IgY) spesifik rabies asal kuning telur. Kegiatan penelitian yang dilakukan meliputi produksi antibodi pada ayam petelur yang telah divaksinasi menggunakan antigen rabies terinaktivasi, pengukuran konsentrasi IgY dalam kuning telur, pemurnian IgY dari kuning telur, pengukuran konsentrasi total protein IgY, karakterisasi antibodi spesifik rabies, penentuan titer IgY anti rabies menggunakan ELISA. Kuning telur yang diketahui positif mengandung IgY spesifik rabies dimurnikan menggunakan dua metode yaitu : 1) pengendapan dengan NaCl; 2) teknik Water Soluble Fraction (WSF), dilanjutkan pengendapan dengan PEG 6000-amonium sulfat. Titer IgY spesifik di tentukan dengan uji ELISA dan karakterisasi protein dengan metode SDS-PAGE. Hasil penelitian menunjukkan bahwa antibodi anti-rabies dapat dideteksi pada kuning telur pada minggu kedua setelah vaksinasi pertama. Purifikasi IgY dengan NaCl menghasilkan konsentrasi 331 μg/ml dan teknik WSF 184 μg/ml. Karakterisasi protein menggunakan SDS-PAGE menghasilkan pita protein pada teknik NaCl dengan berat molekul 164,16 kDa, 126,43 kDa, 97,36 kDa, 68,73 kDa, 40,76 kDa, 28,77 kDa dan teknik WSF dengan berat molekul 94,03 kDa, 65,61 kDa, dan 31,94 kDa. Titer antibodi spesifik menggunakan teknik NaCl lebih besar dari 0,5 EU/ml dan teknik WSF dengan titer antibodi di bawah 0,5 EU/ml . Berdasarkan hasil penelitian, dapat disimpulkan bahwa IgY spesifik rabies dapat diproduksi pada ayam petelur dan menghasilkan antibodi yang titernya cukup tinggi
