Abstract

Energi listrik adalah salah satu kebutuhan masyarakat modern yang sangat penting dan vital [1]. Untuk mengukur daya secara keseluruhan, sumber daya untuk mengukur peralatan dan orang-orang yang mengendalikan penggunaan energi tidaklah murah. Untuk alasan ini, diperlukan sistem pengukuran berbasis Internet of Things dan kecerdasan buatan secara relatif. Sistem akan dikembangkan berbasis web dengan pemrosesan terpusat dan node untuk mengukur daya pada beban. Untuk mendapatkan data, sensor yang dapat mendeteksi tegangan dan arus digunakan, sensor ini akan mengirim data melalui internet dengan menggunakan peralatan IoT untuk menyimpan data ke server. Data akan direkam menggunakan sensor PZEM-004T dan hasil dari data tersebut akan ditambang menggunakan urutan penambangan untuk mendapatkan derajat keanggotaan fuzzy di mana tingkat keanggotaan dimasukkan ke hasil sistem pendukung keputusan konsumsi energi nanti.

Abstract

Technologies that support wireless networks include WLAN (Wireless Local Area Network) and WPAN (Wireless Personal Area Network). One of the most widely used WLAN products today is IEEE 802.11n while the WPAN application is Bluetooth. Using the same frequency band in a coverage area can cause interference. Interference that occurs can be caused due to the use of 2 pieces of the same communication system, as well as different in a region. This study aims to determine how much influence interference has on the decline in the quality of a communication system with parameters measuring bandwidth, jitter, and packet loss. From the results of measurements and analysis shows that network quality is affected due to interference. Where if the network is free from interference around it, the network quality will be better, if the network experiences interference because using the same frequency band in the same coverage area can affect network quality such as reduced bandwidth value, increased jitter, and packet loss as well as channel usage and different channels. And the closer the distance of the access point that uses a different channel in a coverage area will cause the decreasing bandwidth value to increase the value of jitter and packet loss and vice versa. Keywords: interference, wireless, channel, bandwidth, jitter, packet loss.
