Abstract

In this final measurement and analysis of network performance parameters based KPI (Key Performance Indicators) such as the Power Receive of MS (RxLevel), MS Transmit Power (Tx Power), Forward Frame Error Rate (FFER), Signal Strong (Ec / Io), Drop Call Rate and Call Setup Success Rate. From the analysis of test performance based on KPI parameters can be seen that the performance of the BTS Kota Baru and BTS Purnama still below ideal standards set by the company for parameter CSSR (> 97%), respectively 95.63% and 95.95%. As for the parameters to meet the standard KPI (0-2%) DCR respectively 0.26% and 0.27%. Quality calls for CSSR during test drive is also bad (still below the standard KPI) by 85%. DCR is still below the standard of 5%. In the area close to the BTS (<2 km) all successful calls with an average RxLevel still normal between 69% -95%, Ec / Io normal by 7-8 dB, TxPo normal <23 dBm, and FFER 0-5% . While the area is far from BTS (> 2 km) most experienced call drop calls and blocked calls with an average RxLevel no longer normal between> 95%, Ec / Io no longer normal> 9 dB, TxPo no longer normal> 23 dBm, and FFER> 5%. This is what causes the fall in performance CSSR and DCR. The better the RF parameters of the BTS, the less likely it will drop the call and blocked calls. The smaller the drop the call and blocked call quality performance CSSR and DCR will increase (KPI standards). That is, the RF parameters and performance parameters are closely related. To achieve an ideal performance, both performance it must meet the standards of corporate ideal. Efforts that can be done such that the orientation of the antenna sector, then the addition of a repeater to increase coverage power that can be reached, the addition of modules to increase the capacity of CEMA BTS, or the addition of new base stations when the area was still solid drop call and blocked calls.

Abstract

In this modern world, digital technology is rapidly improving, there is much automation being developed nowadays. The door that is used to be opened manually; now can probably be designed as automated too, so it would ease people in doing various activities and the automation is completed by safety system as well, so the door can only be opened by certain people. With the fast improving technology, the author is trying to apply such technology in automating a web-based door. One of the systems is the Automatic Door Opener System based on mini Wemos D1 using the web. This design was an idea that appeared when the author was doing an internship in PT. Aplikanusa Lintasarta. Such safety system was needed in the shelter room to keep the equipment safe inside the room. A design that could ease the technician’s work was needed in solving the problems of PT Aplikanusa Lintasarta costumers. The shelter has an important function in each of its locations, so a safety system is needed to keep each of the important equipment inside the shelter itself. Because the technician is often doing the rehabilitation in its equipment as well as improvement in the disturbance, the author intention is to help the technicians, so they don’t have to bring the shelter keys anymore and for the shelter safety reason itself. This expected to help in monitoring the door’s condition that can be done without having to directly watch for the shelter’s location directly. To ease the technicians’ work and to make them work more efficiently, a tool to open the shelter door and to monitor the shelter door condition is needed wherever the disturbance location is. The safety system will facilitate the technician that needs to reach the disturbance location especially when he forgot to bring the destined shelter key. A study then is being conducted by making a tool in hopes the PT. Aplikanusa Lintasarta main office which is located in Pontianak is being able to monitor and open the shelter door based on the shelter areas using a web-based automatic door detection system. Keywords: shelter, safety, analog, digital, web
