Judul: Analisis kinerja protokol destination-sequenced distance-vector (DSDV) pada jaringan wireless ad hoc
Abstrak: DSDV merupakan salah satu Proactive Routing Protocol yang membutuhkan setiap node untuk mengirimkan paket routing update ke seluruh node tetangganya secara periodik. Setiap node menyimpan tabel routing yang mengandung informasi yang dibutuhkan untuk sampai ke node tujuan. Penelitian ini melakukan simulasi menggunakan aplikasi Network Simulator 2 (NS-2) untuk menganalisis kinerja DSDV pada jaringan wireless ad hoc. Jaringan wireless ad hoc ialah jaringan yang beroperasi tanpa bantuan infrastruktur yang tetap yang umumnya tersedia di jaringan tempat node-node saling terhubung. Parameter kinerja yang dipakai untuk menganalisis hasil simulasi ialah packet delivery fraction, routing overhead, dan normalized routing load. Simulasi dibagi menjadi beberapa skenario untuk mengetahui pengaruh mobilitas node dan trafik terhadap kinerja DSDV. Skenarionya antara lain, selang kecepatan, pause time, jumlah node, luas area simulasi, ukuran paket data, jumlah koneksi maksimum, dan packet rate.

Judul: Analisis kinerja protokol Routing Ad Hoc on demand distance vector pada topologi mesh, ring, tree, dan line pada jaringan wireless Ad Hoc
Abstrak: Wireless ad hoc network is a network that does not have a centralized administration in which each node in addition to acting as a host also acts as a router that forwards packets from one node to another node that is not within the direct reach of each other. Ad hoc on demand distance vector (AODV) routing protocol is one of the routing protocol that used specifically in this kind of environment. This research was performed using Network Simulator (NS-2) to analyze the performance of AODV routing protocol in wireless ad hoc network when used in different topology. The wireless ad hoc networks was formed by 25 wireless static nodes without any centralized administration. The number of traffic flow used in this research were 5, 10 15, and 20 flows. The size of packet generation rates were 0.1, 0.01, and 0.001 second. The observed parameters in this research were throughput, packet received ratio, delay and jitter. The result showed that AODV routing protocol has best performance when used in mesh topology, but in mesh topology the performance tends to decrease faster when the network traffic increased than when AODV routing protocol used in ring topology.

Abstrak: The aim of this study was to analyze the effect of cooking (deep frying) on chemical composition (moisture, protein, ash, and fat), mineral, and folic acid of bull shark meat. The chemical composition, mineral content, and folic acid (vitamin B9) content were determinated by proximate analysis, AAS (Atomic Absorption Spectrophotometer), HPLC (High Performance Liquid Chromatography), respectively. The contents of moisture, protein, ash, and fat of raw sample (wet basis) were 74.09±0.01; 1.33±0.00; 23.56±0.08; 0.56±0.04%, respectively. All of proximate contents were decreased due to frying process, except fat content. The amount of minerals were decreased due to frying, seen in K (18.79%), Mg (26.55%), Na (40%), P (24.04%), Fe (3.42%), Zn (5.12%), Cu (6.39%), in other hand Ca has been increased (49.75%). Folic acid content of raw meat was 1.06±0.003 ppm, and decreased by 49.06% due to frying process.
