Abstract

Collision avoidance multiple access plays a significant role in WirelessSensor Networks (WSN) as there may have a huge number of nodes in a network.Therefore, it has big chance to conflict when they want to send a packet to the server atthe same time. In our work, we focus on the sensor networks with two-tier network designarchitecture that composed of simple function nodes and presented performance analysisof the proposed collision avoidance multiple access protocol for Wireless SensorNetworks, with emphasis on the contention process exercising in each contention subframe.Then we also examine the efficiency of the overall system based on the simulationresults. The results shows that using different parameter of n, m, and k then the successfulprobability tends to increase, however after certain value of n, the successful probabilitywill decrease. Regarding the overall system efficiency, Esys, in order to get the optimumvalue of system efficiency, we have to maximize α. It is obvious that the bigger value of βwill produce bigger value of α. That is mean a shorter contention sub-frame leads to abetter efficiency of the systems, if Lr (average length of transmission sub-frame) is fixed.

Abstract

Reliability of distribution networks is a factor that greatly affects customers as consumers of electricity. Analyzing and calculating the reliability of distribution networks are determined by the reliability index including SAIFI, SAIDI, CAIDI, and ASAI. On the other hand, smartphone technology is growing rapidly with a variety of applications to help simplify and accelerate human work in several fields of work. This paper delivers the design of an Android-phone-based analytic tool for distribution system reliability index measurement by developing it on Android application software. This application is named KALINDA, stands for Kalkulator Indeks Keandalan (Reliability Index Calculator), and created by using Android Studio IDE. We compare the data result between KALINDA calculations and manual calculations. The results obtained from the KALINDA application are declared to be valid accurate.

Cellular communication technology developed from the first generation to the present time has entered the 4th generation known as 4G LTE. The writing of this final project discusses the analysis and optimization of the 4G LTE network of Telkomsel seluer operators in Jombang, East Java. Measurements were made using the drive test method to test the 4G LTE network in the inner area of Jombang district. This testing is done to check the network in the inner area whether it is optimal in providing network to customers. This drive test uses a nemo handy device and to analyze drive test results using a nemo analyzer. The results measured when doing a drive test are RSRP, SNR, and throughput parameters. The results of the RSRP parameter get 95% of the total sample RSRP values -100 dBm to 0 dBm. The SNR parameter gets 94% of the total sample which has a value of 0 dB to 25 dB. The throughput parameter gets 95% of the total sample value above 1Mbps. After a drive test and analysis there are 4 areas that need to be optimized because in terms of quality or SNR and the data speed or throughput is below the standards applied by the operator.

Abstract

This paper presents performance analysis of synchronous generator: a case study in steam power plant PT POMI Paiton unit 7 Probolinggo, East Java, Indonesia. The steam power plant is the most powerful in Indonesia. The dominance of this type of power plant can be seen from statistical data that until the end of 2018 there were 48.43% of steam power plants out of the total installed capacity of national plants. Generators used in steam power plants are generally of the synchronous generator type, which in its operation always experiences dynamics from time to time as the load changes in electricity. In this study, an analysis of the performance of synchronous generators has been carried out concerning changes in electricity load. Synchronous generator performance analysis includes output voltage, active power, reactive power, power factor, and generator efficiency. The steam power plant in this study is the largest capacity power plant in Indonesia, thus providing an important role in the supply of electric power. Based on the results of the study, it has been shown that although the load dynamics that experience changes are very dynamic, the generator performance still has good performance.

Abstract

Telecommunications technology is always developing every time from the beginning of the emergence of the first technology known as 1G in 1980 until now its development is growing rapidly, in this year 2019 telecommunications technology is using 4G technology that is sophisticated enough, to balance the sophistication, it must have efficient telecommunications procedures so that more optimal. One way to make the procedure more optimal, especially in paging, is by modifying the core network configuration located on the SGSN, from the initial use of the paging configuration to the adaptive paging configuration and prove whether it is more optimal by comparing the two configurations. The results of research that have been obtained from PT Indosat Ooredoo is that on SGSN Banjarmasin 4 (SGBJM4) an increase in the percentage of Paging Success Rate (PSR) of 0.96%. In SGSN Banjarmasin 5 (SGBJM5), the percentage value increased 0.1%. In SGSN Pontianak 1 (SGPTK1) an increase in the percentage value of 0.04%. As for the RRC Paging Discard Ratio (PDR) decreased when using the adaptive paging configuration by 48.85%.
