Abstract

Regarding increasing of load demand every year, it is necessary to provide power in largeammount which directly involved operation cost especially fuel cost. Therefore, to minimizethe fuel cost, should used an optimization technique that is Random Unit Outage, whichresult not only in minimum operation cost but also reliability level of the system. thisoptimization technique is divided into three steps by three methods; Gradien method,Dynamic Programming, and Convolution method. To test method, it is implemented forJawa-Bali hydrothermal power system of PT PLN (PERSERO) P3BKeywords: interkoneksi, outage, biaya energi terputus

Abstract

Fiber attenuation caused by chromatic dispersion and modal dispersion is commonlyreferred to as a dispersion power penalty. In the wave transmitted by transmitter, dispersionoccurred, caused degradation of signal quality, so that the signal receiver is not as good aswhich is being transmitted. In this paper will be discussed about the impact of dispersionpower penalty in ring-1 STO Gatot Subroto area. Analysis was done to several factors thatcan cause dispersion power penalty, which are distance, wavelength, and data rate beingused. The calculation with available data and specification has been done, so that the routeswith the biggest and the smallest dispersion power penalty can be detected. The biggestdispersion power penalty happened in Palma Citra – Umawar route at distance of 9.387 kmwith  =1550 nm and data rate 622.08 Mbps. While the smallest was 1.221 7 10  dB,happened in Tifa – STO Gatot Subroto route at distance of 1.626 km with =1310 nm anddata rate 155.52 Mbps. All those calculations were still in permissible limit, not more than 2dB. Furthermore from some routes were obtained very small dispersion power penalty. Thebigger the fiber length and data rate, the bigger the dispersion power penalty is. Finally itcan be concluded that fiber length, wavelength, and data rate are equivalent to thedispersion power penalty.Keyword: fiber optic, dispersion, Synchronous Digital Hierarchy

Abstract

Frame relay, according to its name, is a technology that depends on frames that’s beingrelayed in a data transmission. This technology is a simplified form of packet switching,similar in principle to X.25, in which synchronous frames of data are routed to differentdestinations depending on header information [Bates,2002:57]. A regular analysis on networkperformance and quality must be taken to guarantee certain service level. This task is soimportant as frame relay usually carries data on high speed data communication backbone.The performance analysis from the Frame Relay network will be discussed at the providingcompany. Performance analysis is useful to know the quality of service from the Frame relaynetwork . To analyze the quality of service from the Frame relay network can be seen from themeasurement that can affect the network. There are three measures which can affect thenetwork significantly such as bus utilization, excess burst percentage and dropped packetpercentage. Those three are closely related and having significant impact on overall framerelay’s network quality. Based on the results from the networks analyzed shows that it hasenough processing power and bandwidth resources, eventhough nearly 30% of their networkpath is under specified service level guarantee. Even so, overall quality of frame relaynetwork meets the specified service level quality.Keywords: Frame Relay, Bus Utilization, Excess Burst Percentage, Dropped PacketPercentage
