Abstract

Based on the survey data of optical fiber service, the communication network uses optical fiber transmission medium is not maximal yet, because there are some errors in the network, such as the percentage of Network Post Dialing Delay in system is 97.5%, that means there is 2.5% of error a delay occurs in the network when making a call. This research was conducted by analyzing the fiber attenuation of fiber-optic communication systems performance on the link Padang-Bukittinggi in PT. Telkom Padang, SKSO division which uses single mode fiber optic cable types G655. Instrument in this study is the Power Meter and OTDR JDSU MTS-6000 type. Link Power Budget method is used to determine the performance of optical fiber communication systems caused by attenuation based on the value of the received power output. Obtained results on the link Padang-Bukittinggi highest attenuation occurs in core 5 with 26.7226 dB attenuation value and cable length 115 016 km, and in core 7 with 26.1812 dB and cable length 94 462 km. This value is still below of PT. Telkom standard with 28.10352 dB for core 5. While the attenuation value at 7 cores exceeds standard attenuation values​​, with 24.18186 dB, so the performance of the core is declared bad and needs to be evaluated. From optical fiber attenuation value, result of the link power budget analysis is obtained from the calculation of the value of Rx is smaller when compared with -27 dBm the value of Rx sensitivity, it can be said the performance of optical fiber communication systems on the link in the normal state and can be used to operate because the power output can be accepted by the receiver in the device. Keywords: fiber optic cable, optical fiber attenuation, SKSO, link power budget.

Abstract

This research was focus on the low of student’s learning outcome, specially on Basic Electricity and Electronics subject at SMKN 1 Sumatera Barat. The objective is to reveal the comparisons of applying inquiry learning model and problem based learning model to the subject. By using Quasi experimental with simple random sampling; one of probability sampling tecnique, the Inqury model was enducted in experiment class and The Other class where PBL learning model, was also implemented to compare the treatment. The primary data was collected by structured  test (Pre-test and Post-test) according to basic competences described of the subject. based on the t-test result, complying the pre-requisite test such as normalityexamination, this research found that t0≥t ≥ t0 (-2,052 ≥ 2,55  ≥  2,052). However, the result has shown that inquiry learning model is providing better student’s learning outcome than PBL model. Therefore, the inquiry model is more effective than PBL model as research conclusion.Keywords: learning outcomes, learning model, Inquiry, Problem Based Learning.

Abstract

This study aims to analyze the performance of a fiber optic communication system to link Batusanggkar – Lintau PT.Telkom. The tools used are the OTDR and optical power meter. Type of optical fiber used is an optical fiber with G.655. Core optical fiber studied as much as 8 cores. The average attenuation of each core generated based on the OTDR is 0.22139 dB/km, while the average attenuation measurements of each core based power meter that is 0.236075 dB/km. Average attenuation OTDR and power meter still below the values ​​calculated in reference to the ITU-T standard is 0.285448 dB/km. Results of power link budget calculations on each core with a cable length of 34,665 km with total average attenuation of each core 9.84019 dB and output power received is -8.51019 dBm receiver, then the value of the link power budget calculations compared with Rx transmitting device sensitivity (-27 dBm = 0.002 mW), where the value of the calculation is smaller than the Rx sensitivity. It can be concluded that the performance of an optical fiber communication system to link Batusanggkar - Lintau which has worked well and normal. While the rise time budget analysis results indicate that the value of the overall system rise time exceeds the maximum standard of 35% RZ bit period of 10 Gbps bit rate is 35 ps (53,689 ps> 35 ps).

Abstract

This research was motivated by a decline in performance on the BTS Batang Marau, which indicates the level of Rx Level, Rx Qual and SQI not meet KPI targets, so the presence of the area around the base stations that do not meet the standard Rx Level to make phone calls (blankspot). The purpose of this study was to determine the performance of GSM 900 and 1800 networks, as well as to improve the performance of base stations Batang Marau Power Link Budget calculation method. This study discusses the improving performance of GSM network at the site decreased performance, where performance is observed through measurement results based on the data drive test. The results of data analysis showed : (1) From the analysis, GSM 1800 already meet KPI targets for Rx Level >95 %, Rx Qual >94 % and SQI >93 %. In GSM 900 results analysis and Rx Qual SQI already meet the target KPI Rx Qual  >94 % and SQI >93 %, while the results of the analysis of Rx level at 09.00 already reached the target KPI >95 %, at 15:00 and 20:00, still has not reached the target KPI <95 %, which indicates the time of measurement using tools Tems Investigation, there are several areas that Rx the level of poor quality. (2) Value Rx level in the area around the base stations are <-95 dBm indicates blankspot area (can lead to a drop call). (3) The estimated increase in performance on the GSM network by the method of link power budget on the BTS Batang Marau  shows 69.3 dBm Rx Level (Good quality) at a distance of 2.5 km, so it can be concluded that the performance of GSM 900 base stations have been increased Batang Marau performances.
