<p><em>Abstrak</em> – <strong>Internet Protocol Television (IPTV) dengan data real time sangat sensitif terhadap paket yang hilang dan terlambat jika koneksi IPTV tidak begitu cepat. IPTV menggunakan Internet Protocol (IP) melewati jaringan broadband untuk pengiriman sinyal televisi digital yang mempunyai kecepatan data tinggi. Pengamatan dan analisa lebih fokus pada pengukuran live streaming dan pengambilan data secara real time di area Darmo, Surabaya. Pengukuran tersebut meliputi pengambilan data melalui aplikasi VLC Media Player dengan bantuan capture software wireshark dan implementasi layanan IPTV berbasis Internet Group Management Protocol (IGMP). Layanan IPTV ini menggunakan data realtime yaitu waktu live streaming, source, destination, protocol, dan length.</strong></p><p><strong></strong><br /><em>Abstract</em> - <strong>Internet Protocol Television (IPTV) with real time data is very sensitive to lost and late packets if the IPTV connection is not so fast. IPTV uses Internet Protocol (IP) over broadband networks to transmit digital television signals that have high data rates. Observation and analysis focus more on live streaming measurements and data retrieval in real time in the Darmo area, Surabaya. These measurements include taking data through the VLC Media Player application with the help of capture Wireshark software and implementing IPTV services based on Internet Group Management Protocol (IGMP). This IPTV service uses realtime data, live streaming time, source, destination, protocol, and length.</strong></p><p><em><strong>Keywords</strong> - IPTV, IGMP, software wireshark, bandwith</em></p>

Wireless technology based on the IEEE 802.11 standard and in accordance with the KEMINFO 2019 regulations requires antennas that can adapt to changing environments. Microstrip antennas are a good solution to meet the current technological advancements because they have several advantages, such as a simple design, lightweight, easy manufacturing, and low cost. When designing a microstrip antenna, bandwidth parameters must be observed. The bandwidth of a microstrip antenna is narrow. In order to work properly, some simple techniques can be used to increase antenna bandwidth. This research proposes a reconfigurable microstrip antenna polarization using a U-slot at a frequency of (2.4– 2.485) GHz for WLAN applications. The proposed antenna reconfiguration utilizes two (2) switching mechanisms that can be turned on and off individually or simultaneously. The results of the simulation showed that Ant. 1 and Ant. 2 have a linear polarization (LP), Ant. 1 has a bandwidth of 85 MHz (2.399 – 2.484) GHz, and Ant.2 has a bandwidth of 87 MHz (2.398– 2.485) GHz, both with S-parameter values ≤-9.54 dB. Then, Ant. 3 has a right circular polarization with a bandwidth value of 124 MHz (2.397 – 2.484) GHz, and Ant. 4 has a left circular polarization with a bandwidth value of 87 MHz (2.398 – 2.485) GHz at the Axial Ratio (AR) limit of ≤ 3 dB.
