WLAN Controllers Device Abstract: Monitoring of a network is important to support services to customers. This includes internet access services through WLAN technology owned by PT. Telkom namely Indonesia Wifi. PT. Telkom Akses is a subsidiary of PT. Telkom which provides and maintain good quality of Indonesia Wifi services. Assurance Division is one of the business units at PT. Telkom Akses, which has the task of carrying out the maintenance service process. Therefore, this division is required to always monitor the service so that repairs can be done quickly when errors are found. But there are still obstacles in carrying out these tasks, this is due to the results of monitoring the current monitoring system which is still obtained by downloading manually from the WLAN Controllers Device so that it takes a long time to repair the network. The integration of WLAN Controllers Device and the website-based Google Maps API using the Cron Job technique was built using the Rational Unified Process (RUP) methodology as a system development method. WLAN Controllers Device is a data monitoring center and Google Maps API as a display of monitoring network data through a website which will then be integrated with the Cron Job technique to connect the two systems. The result of this monitoring system can facilitate the flow of data monitoring WLAN devices quickly and eliminate ineffective workflows to approximately 30%, while the speed of conducting maintenance services to access point locations with down status increases by 40% after using this system. It is hoped that the integration of this system will be able to assist the maintenance process of Indonesia Wifi services by speeding up data processing of WLAN device conditions.","PeriodicalId":31964,"journal":{"name":"Matrix Jurnal Manajemen Teknologi dan Informatika","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75121219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In regional planning of Manggis village in Karangasem Regency, Bali, the contour map of the land based on a combination of Global Positioning System (GPS) data and Aster satellite imagery data can be used to make drainage planning, roads and tourism accommodation based on the environment. The process of digitizing satellite imagery uses Arc View GIS 3.3 software, namely a geographic information system program which is a special information system that manages data that has spatial information, so that the program can convert satellite imagery data into ground contour maps. Certain objects such as roads, houses, rice fields, gardens and others that were previously in raster format in a satellite image are converted becomes digital format, including: horizontal datum used, the suitability of element names according to the objects / elements being plotted, withdrawal lines in accordance with the appearance of the image.

Sistem penerima correlation receiver diimplementasikan guna mengatasi masalah yang timbul akibat efek dari multipath fading . Untuk memperoleh sinyal dengan nilai error minimum, maka diperlukan analisis terkait proses transmisi pada masing-masing komponen multipath . Hasil analisis diperoleh bahwa unjuk kerja dari Kode PN ( Pseudo Noise ) pada kanal frequency selective fading yang lebih baik adalah variasi komponen multipath = 3 dibandingkan dengan variasi komponen multipath = 6 dan yang paling buruk adalah variasi komponen multipath = 7. Hal ini dibuktikan dengan melihat nilai Bit Error Rate (BER) saat Energy Per Bit To Noise Power Spectral Density Ratio (Eb/No) = 10 dengan komponen multipath = 3 memiliki nilai BER Abstract: Barriers to the Line of Sight ( LOS ) can cause diffraction, reflection and scattering of information signals which will reduce the quality of information received on the receiving side. This results in a constructive and destructive nature of the signal at the receiving end. Examples of destructive properties that often occur are fading and delay. The receiver correlation system is implemented to overcome the problems that arise due to the effects of multipath fading. To obtain a signal with a minimum error value, an analysis is needed related to the transmission process for each multipath component. The analysis results show that the performance of the PN code (Pseudo Noise) on the frequency selective fading channel is best when the multipath component variation = 3 compared to multipath component variation = 6, and the worst is multipath component variation = 7. This is proved by the value of BER when Eb/No = 10 with multipath component = 3 has BER value of 0.00368, while multipath component = 6 and multipath component = 7 have BER values of 0.00386 and 0.00507 respectively. Based on these results it can be concluded that the number of multipath components have an effect on the quality of the received signal.","PeriodicalId":31964,"journal":{"name":"Matrix Jurnal Manajemen Teknologi dan Informatika","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84023728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system is compared by first simulating using a flat fading channel in ideal conditions. The results of the simulation show that the performance of the Walsh code performance communication system on multipath fading channels has increased BER value when the number of multipath components is added. This is due to the greater number of multipath components to be used, so the greater number of reflected signals will interfere with the desired signal at the receiver.","PeriodicalId":31964,"journal":{"name":"Matrix Jurnal Manajemen Teknologi dan Informatika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83214550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
