Analisis Kualitas VoIP pada SCTP Menggunakan ECN dan AQM
Authors: Surimi La , Pulungan Reza 
Published: January 2017

AbstrakVoIP merupakan aplikasi real time yang kualitasnya sangat tergantung pada delay dan jitter, yang mana hal ini sulit dipenuhi oleh protokol yang bersifat reliable dan memiliki congestion control seperti TCP. Di sisi lain penggunaan UDP yang tidak memiliki congestion control menyebabkan peluang terjadinya congestion pada jaringan sangat besar. Penggunaan SCTP sebagai protokol alternatif juga belum mampu mengakomodasi kekurangan TCP dan UDP. Beberapa hasil penelitian menunjukkan perlu adanya perbaikan ataupun modifikasi pada mekanisme congestion control yang dimiliki oleh SCTP. Penggunaan mekanisme ECN dan AQM pada beberapa penelitian menunjukkan bahwa kedua mekanisme ini dapat menurunkan delay dan jitter. Penelitian ini melakukan pengujian terhadap kualitas VoIP di atas SCTP yang menggunakan ECN dan AVQ pada network simulator NS2. Hasil simulasi menunjukkan bahwa penggunaan mekanisme ECN dan AVQ pada protokol SCTP menghasilkan kualitas VoIP yang lebih baik pada kondisi jaringan yang tidak ideal (high Latency low Bandwidth dan low Latency low Bandwidth dari pada penggunaan protokol SCTP tanpa menggunakan mekanisme ECN dan AVQ. Penelitian ini juga melakukan perbandingan nilai MOS panggilan VoIP SCTP yang menggunakan ECN dan AVQ dengan nilai MOS panggilan VoIP yang menggunakan protokol TCP dan UDP. Hasilnya SCTP dengan ECN dan AVQ mengungguli TCP namun belum dapat mengungguli UDP. Kata kunci— VoIP, SCTP, ECN, AQM,AVQ. AbstractVoIP is the real time applications that are highly dependent on the quality of delay and jitter, which it is difficult to be met by protocol that has reliable data transfer feature and congestion control such as TCP. On the other hand the use of UDP that has no congestion control make chance of causing congestion in the network is very large. The use of SCTP as an alternative protocol was also not able to accommodate the weaknesses of TCP and UDP. Some research shows that repairs or modifications to the SCTP congestion control mechanism is needed.The Use of ECN and AQM in some studies show that these two mechanisms can reduce delay and jitter. This study tested the quality of VoIP over SCTP with ECN and AVQ, in NS2. Simulations carried out by independent replication technique, and the results showed that ECN and AVQ can increase the value of MOS VoIP calls significantly in non ideal network scenarios. This study also did comparison of SCTP MOS that uses ECN and AVQ with MOS values VoIP using TCP and UDP. The result showed that SCTP with ECN and AVQ outperform TCP but can not surpass UDP yet. Keywords— VoIP, SCTP, ECN, AQM,AVQ.

Published: January 2017

AbstrakLayanan komunikasi Instant Messaging menyediakan berbagai fitur komunikasi yang bisa digunakan oleh pengguna, diantaranya adalah text messaging (pesan teks) baik online maupun offline. Salah satu standar protokol yang mendukung layanan ini adalah XMPP (Extensible Messaging and Presence Protocol). Aliran komunikasi XMPP menggunakan potongan dokumen XML, sehingga rentan terhadap serangan pasif monitoring konten paket komunikasi. Untuk mengatasi kelemahan ini solusinya adalah menggunakan komunikasi yang terenkripsi. Selain itu ada solusi lain yang coba ditawarkan dalam penelitian ini, yaitu penggunaan covert channel untuk mengirim pesan secara tersembunyi. Dalam penelitian ini akan dibuat sebuah aplikasi klien XMPP berbasis web browser yang mampu melakukan komunikasi XMPP dan juga menyediakan komunikasi covert channel. Komunikasi XMPP agarbisa berjalan diatas aplikasi berbasis web browser maka digunakanlah protokol WebSocket. Protokol inilah yang nantinya akan dieksploitasi pada sisi header, khususnya pada field masking-key untuk memuat pesan covert channel yang dikirimkan pada saat sesi komunikasi XMPP berlangsung. Dari hasil ujicoba, aplikasi klien covert channel mampu menghasilkan komunikasi dengan lebar data 3 byte perpaket. Aplikasi Klien juga mampu melakukan komunikasi covert channel pada kondisi link komunikasi dengan tingkat probabilitas packet loss dibawah 10%. Kata kunci— WebSocket, XMPP, masking-key, Covert Channel, aplikasi klien berbasis browser. AbstractInstant Messaging communication services provide a variety of communication features that can be used by the user, such as text messaging (text messages) both online and offline. One of the standard protocol that supports this service is XMPP (Extensible Messaging and Presence Protocol). XMPP communication using XML documents, making it vulnerable to passive attacks monitoring content of communications. To overcome this drawback the solution is encrypted communications. The other solutions that try to offer in this research is the use of a covert channel to send hidden messages. In this research will create a browser based XMPP client application that is capable to deliver XMPP communication and also provide covert channel communication. XMPP communication can be built on a web-based application using WebSocket protocol. This protocol will exploit field masking-key to load the covert channel messages that is sent during the session XMPP communication takes place. From the test results, the client application is able to produce a covert channel communication with a data width of 3 bytes in each packet. The client application is also able to perform covert communication channel in a communication link with the condition of the probability of packet loss rate below 10%.

Transformator daya merupakan peralatan yang vital dalam penyaluran energi listrik dari unit pembangkit menuju sistem jaringan saluran tegangan. Kehandalan transformator daya sangat penting untuk keberhasilan operasi dari sistem tenaga listrik. Untuk itu dilakukan pendekatan sistematis dengan cara mengetahui kondisi peralatan komponen utama dari transformator daya tersebut. Transformator secara ideal memiliki useful life sesuai dengan design life yang direkomendasikan yaitu 30 tahun. Sedangkan transformator daya PT X sudah tidak berada dalam range useful life, dimana transformator daya tersebut diproduksi oleh Takaoka Electric pada tahun 1976. Oleh karena factor usia transformator yang sudah berumur maka diperlukan inspeksi khusus secara mendalamsebagai pendukung untuk membuat keputusan pembatasan operasi atau keputusan investasi pembangkit secara tepat dan tidak merugikan unit pembangkit itu sendiri. Untuk itu penulis melakukan serangkaian pengujian dan analisa penilaian kondisi transformator daya PT X untuk memperoleh nilai kondisi dengan mengacu pada referensi penilaian HAP (Hydro Power Advancement Project). Hasil penilaian kondisi diharapkan nantinya akan digunakan sebagai bahan pendukung tindak lanjut pengambilan keputusan oleh PT. X.

DIALEKTIKA AL-QUR'AN DENGAN POLA PIKIR KEBERAGAMAAN MASYARAKAT ARAB: Analisis Psiko-Sosial
Authors: Wathani Syamsul 
Published: January 2017

This article discusses the mindset of Arab society towards religion which is answered and it was changed after the Koran came. This relationship is dialectic, the Arab community as khitab al-Qur’an. The approach used by the social history of social psychoanalysis. With this approach, this article found some important conclusions. (1) Social history emphasizes that geographic factors, psychological, and social culture have shaped their social siko. Psycho-social impact on their perspectives on God and Religion. God was related to a god (dewa) who can help the biological necessities of life, although not psychologically soothing. As the unsound of the psico-social condition, the way they understand the religions is not correct. They profess religion, somehow does not feel the presence of God. The more they worship Gods, the more discrepancies, social injustices, and tyranny happen. Responding to that matter, the Quran apply persuasive method as the advice (al-din al-nasihah), and discussion (jidal) as their way of thought on religion. (2) The Qur'an came alter their patterns of psychological evolution, from an-nafs al-ammara as bi-su’ society into an-nafs al-lawwamah, until in the end, they had a quiet soul (an-nafs al-Mutmainnah)

Published: January 2017

Field identification of the White-footed Mouse (Peromyscus leucopus noveboracensis) and Long-tailed Deer Mouse (Peromyscus maniculatus gracilis) is difficult because of their similar external morphology. Peromyscus were sampled by live-trapping during a five-year period (1992-1996) at the Arnot Teaching and Research Forest, Van Etten, New York and identified to species by electrophoresis of their salivary amylase. No electromorphs were shared between P. leucopus and P. maniculatus, thus permitting unambiguous species identification of individuals. Means and ranges of four external measurements (ear, head-body, hind-foot, and tail) and tail to head-body ratio were determined for amylase-genotyped live mice. Although some body measurements did differ on average between the two species (ear, head-body, and tail for adults; hind-foot and tail for juveniles), the ranges of these overlap considerably. When the four external measurements (excluding the tail to head-body ratio) were used to construct two discriminant-function equations, they yielded correct identification of 80% of the adult P. l. noveboracensis and P. m. gracilis assessed excluding juveniles, and 71% of adult and juvenile mice combined. The function reported here allows partial field identification, but genetic analysis remains the only reliable field method for differentiation between live P. l. noveboracensis and P. m. gracilis.

Repeatability of Foraging Tactics in Young Brook Trout, <em>Salvelinus fontinalis</em>
Authors: Biro Peter A. , Ridgway Mark S. 
Published: January 2017

In this study, we repeatedly observed individually marked Brook Trout in a field setting to determine if the bimodal variation in foraging tactics previously observed in young salmonid populations (without distinct morphological differences) is generated by individuals specializing at different foraging tactics. We found significant but low repeatability in several foraging movement parameters. This indicated that while individuals did have tendencies to be sedentary versus highly active, there was considerable variation in foraging activity within individuals. These results suggest that relatively consistent differences among individuals may facilitate selection for specialized morphology and that there may be a heritable component to activity. Erratum included.

We compare diet and feeding behaviour of Snapping Turtles (Chelydra serpentina) and Midland Painted Turtles (Chrysemys picta marginata) in Algonquin Provincial Park, Ontario, Canada. We observed young Chelydra and Chrysemys turtles feeding on insect and amphibian larvae in ephemeral ponds, adult Chrysemys terrestrially foraging on odonate larvae, and adult Chelydra consuming aquatic vegetation and seeds. These and other observations highlight the importance of seasonally available habitat and food for juvenile turtles. We also discuss the evidence for, and importance of, turtles as seed-dispersal agents for aquatic vegetation. Illustrative video recordings accompany our dietary observations.
