Pada tulisan ini dibahas tentang bagaimana implementasi layanan IPTV terbaik dengan dua alternatifpemilihan teknologi, yaitu Multi Service Access Node (MSAN)atau Gigabit-Passive Optical Network(GPON),berdasarkan jarak pelanggan terhadap lokasi dari pemberi layanan IPTV tersebut. Untuk keperluantersebut dilakukan analisa terhadap parameter QoS dari layanan IPTV (yaitu Signal to Noise Ratio,Transmission Losses, Line Attenuation, dan Delay),baik yang menggunakan jaringan akses network MSAN,maupun yang menggunakan jaringan akses Gigabit-Passive Optical Network (GPON).Berdasarkan pengukuran dan perhitungan maka untuk memperoleh kualitas layanan IPTV yang baik, jarakmaksimal pelanggan dengan MSAN adalah 1 km. Bila jarak lebih dari 1 km maka diperoleh attenuasi dan rugitransmisi sangat tinggi, sehingga kualitas layanan IPTV menjadi kurang baik. Oleh sebab itu untuk jarak lebihdari 1 km dapat digunakan jaringan akses network FTTH-GPON, dimana redamannya kecil dan tidaktergantung oleh jarak pengkabelan. Dengan demikian jaringan akses FTTH-GPON merupakan solusi terbaikuntuk pelanggan didaerah yang berlokasi lebih dari 1 km terhadap MSAN/Remote DSLAM atau daerah yangtidak dimungkinkan bagi pemasangan MSAN.

<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>

Background: In order to better understand the posttraining suicide prevention behavior of gatekeeper trainees, the present article examines the referral and service receipt patterns among gatekeeper-identified youths. Methods: Data for this study were drawn from 26 Garrett Lee Smith grantees funded between October 2005 and October 2009 who submitted data about the number, characteristics, and service access of identified youths. Results: The demographic characteristics of identified youths are not related to referral type or receipt. Furthermore, referral setting does not seem to be predictive of the type of referral. Demographic as well as other (nonrisk) characteristics of the youths are not key variables in determining identification or service receipt. Limitations: These data are not necessarily representative of all youths identified by gatekeepers represented in the dataset. The prevalence of risk among all members of the communities from which these data are drawn is unknown. Furthermore, these data likely disproportionately represent gatekeepers associated with systems that effectively track gatekeepers and youths. Conclusions: Gatekeepers appear to be identifying youth across settings, and those youths are being referred for services without regard for race and gender or the settings in which they are identified. Furthermore, youths that may be at highest risk may be more likely to receive those services.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.
