    Bangko Offices Area in PT. Chevron Pacific Indonesia require a network with reliability, stability, and efficiency to support the company. Currently, there are many problems that occur in today\u27s network such as the link that was frequently interrupted, no backup paths in the network, and the speed of the link is still not uniform. Therefore, it is important to design a new network to solve that problem. In the new network design, used a ring topology plus additional backup lines, 1 Gbps bandwidth allocation, and the use of the spanning tree protocol. The design of the new network is done by using software OPNET Modeler with the parameters are delays and throughput. The needs of planning for next 5 years will be fulfilled with 1 Gpbs bandwidth alocation and the implementation of the spanning tree protocol will avoid loops and maintain network connectivity. With the new network design will be obtained a good Quality of Service with the network delays value corresponding to the category of delay and regularly use the service based on the priority determined

    Cell phones have become a major part of the society in daily life - today. The use of mobile phones has spread in every community, rural and urban. SingTel, Hutchison, Comindo Axiataand Indosat are some operators cellular telecommunications network that use UMTS and HSDPA technology. The parameters that determine the power level and the quality of the signal strenght of each operator is known as RxLevel (the Receptiom Level) for GSM and the RSCP (Received Signal Code Power) in order to WCDMA. One of methods for analyzing to measure that parameters is a drive test which use rf signal tracker software. This research will compare a drive test method with simulation method, where the simulation using radio mobile software. The location of this research is in some protocol streets on Pekanbaru, such as Cut Nyak Dien Street, Jend. Ahmad Yani Street, Ir. H. Juanda Street, Gajah Mada Street, Diponegoro Street and Jend. Sudirman Street. The result shows that Telkomsel has the best signal strength in protocol streets on Pekanbaru with -63.082 dBm, followed by XL Axiata with -68.187 dBm, then Hutchison with -75.082 dBm. The lowest signal strenght is operator Indosat with the value -86.411 dBm

    FM demodulator is used to demodulate signal in FM receiver. Demodulation process is performed to recover the information signal. The information signal is 3.4 kHz which ismodulated with a carrier signal of 19 kHz. FM demodulator is designed with PLL (Phase Locked Loop) method, it used the concept of phase locking signal. FM demodulator withPLL method consist of four blocks, that is phase comparator, second-order Butterworth LPF, VCO wienbridge, and buffer amplifiers. Design of FM demodulator trainer begins with calculate to determine the component value which suitable with cut off frequency. The next process to make the layout of the pcb board, dissolution layout, pcb board drilling, mounting the female connectors to pcb board, installation of component connectors to the header, and make a box to place trainer FM demodulator. The results obtained at each signal FM demodulator block is different. Demodulated signal is obtained at the buffer amplifier block, where the signal is same as the output signal at function generator is 3.4 kHz

    Analisa Perbandingan Quality Of Service (QoS) pada Jaringan Backbone Non-MPLS dengan Jaringan Backbone MPLS Menggunakan Routing Protocol OSPF di PT. Telekomunikasi Indonesia, Tbk. Witel Ridar Riau

    The development of telecommunications technology based on Internet Protocol (IP) is now growing with the competitiveness of the telecommunications company to improve the quality of service to consumers. It can be obtained by increasing the quality backbone network using Multi Protocol Label Switching (MPLS). MPLS is a new technology to forward the packet to the backbone network without changing the existing network structure. The main idea is to construct a replacement MPLS paths using label switching and distribute traffic into it. This paper compare the Qualty of Service (QoS) on Non-MPLS backbone network to MPLS backbone network with OSPF routing protocol on the PT. Telecommunication Indonesia, Tbk. Witel Ridar Riau. The Software simulation using Graphical Network Simulator (GNS3) is analyze by observing QoS are delay, packet loss, throughput, and jitter with Wireshark. In this research, there are two scenarios that will be analyzed. The first scenarios analyze the customer site make deliveries to one another customer site and the second scenarios analyze two customer sites make deliveries to the customer site simultaneously. The results show that the highest delay in the first scenario is better MPLS backbone network at 0.029999 s and 0.0124 s in the second scenario than Non-MPLS backbone network. It Followed by the highest value of packet loss on the network backbone MPLS and non-MPLS are equal 0% and in the second scenario, MPLS is better 0% than non-MPLS. The Throughput has same trend with the highest value in the first scenario MPLS backbone network is better 0.0085 Mbps and 0011 Mbps in the second scenario than Non-MPLS backbone network. Meanwhile the highest jitter values in the first scenario MPLS backbone network is better too at 0.3595995 s and 1.544403 s on the second scenario than the non-MPLS

    Routing and Medium Access Control (MAC) in wireless sensor network for monitoring emergency applications

    This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonIn recent years, Wireless Sensor Networks (WSNs) have been implemented in many applications including emergency applications. Emergency applications require different characteristics than others, such as robust communication, low energy consumption and minimum end-to-end delay. Routing and Medium Access Control (MAC) are two protocols that have been used by many researchers to achieve those requirements. This thesis mainly focuses on studying distributive clustering routing and MAC protocol for emergency applications. To design robust communication in emergency applications, this thesis has proposed a modified LEACH protocol considering the health status of sensor nodes. LEACH is a benchmark protocol employing distributive clustering-based routing with low energy consumption, however this protocol is not suitable for emergency applications. The health status refers to the condition of nodes, safe or in danger, with the danger status shows the high probability to be destroyed sooner because of external factors such as fire. The proposed approach avoids selecting the nodes in danger as cluster heads. Furthermore, efficient multi-hop communication is employed to minimise energy consumption. The simulation result shows that total data received, energy consumption , packet delivery ratio, and energy efficiency of the proposed approach are stable with an increasing number of destroyed nodes. Furthermore, a grid-based clustering approach with health status is proposed to further enhance energy constraint and robust communication. The proposed approach includes distributive clustering and incorporate constant number of CHs in every round. The remaining energy, the health status of node, and the distance to the centre of the grid are consided when choosing the cluster head. Simulation results have revealed that the proposed protocol has a significant effect on the time for first node to destroy due to energy consumption, an increase of 45% compared to LEACH. Furthermore, packet delivery ratio of the proposed approach is enhanced by 16% compared to LEACH. In order to reduce end to end delay, a priority-based grid Time Division Multiple Access (TDMA) has been proposed. In this approach, traffic is classified into two categories: emergency traffic from danger nodes, and monitoring traffic from safe nodes. This scheme was implemented using three steps: formation of a new TDMA frame, the arrangement of slots and priority allocation. Simulations results showed an improvement of around 65% and 70% in end to end delay compared to Grid and LEACH approaches.Directorate General of Resources for Science, Technology, and Higher Education of Indonesia; the University of Ria
