Kebutuhan informasi dan semakin majunya perkembangan teknologi mendorong lahirnya Teknologi Informasi dan Komunikasi yang dapat memberi efektifitas dan efisiensi kerja manusia. Akses internet yang juga mudah dijangkau, kapan saja, dan dimana saja memicu lahirnya integrasi semua teknologi dan aplikasinya. Telepon, e-mail, instant messaging, bahkan video conference, mulai didorong agar dapat saling terintegrasi dan sinkron sehingga berbagai jenis aplikasi dan coba. Didapatkan bahwa QoS berupa delay, jitter, packet loss, dan throughput tidak mengalami perubahan yang signifikan dan masih memenuhi standar ITU-T. Nilai delay yang didapatkan sebelum pengamanan SIP sebesar 33,974 ms, sedangkan setelah implementasi secure-SIP naik menjadi 39,964 ms. Untuk nilai jitter dengan dan tanpa menggunakan secure-SIP sekitar 0,6 ms. Tidak ada paket yang hilang, dalam hal ini nilai packet loss sebesar 0%. Sedangkan nilai throughput sekitar 50 paket/detik. ......Information needs and more advanced technological developments led to the establishment of information and communication technology which allowed human to work more effectively and efficiently. Internet access which available in anytime and anywhere, also triggered the integration of all means of technology and its applications. Telephone, e-mail, instant messaging, even video conference, are all begin to be integrated and synchronized so that they all could be accessed all at once, in a single device or application. As a new technological advancement, Unified Communications is expected to not only serve the business world, but also education, to increase the effectiveness and efficiency in conducting their daily activities. But this integration and ease comes with some unfavorable aspect. Security aspect becomes a very important part to support quality of services. This final paper was implemented the IP telephony for VoIP application with security scenario on different SIP protocol: RTP (non-secure), SRTP, and SSL. Then, the the performance and security on IP Video Telephony after and prior to the implementation of secure-SIP method was analyzed. The results show that QoS in forms of delay, jitter, packet loss and throughput, did not reveal significant changes and is still within the standard of ITU-T. Delay measurement prior to the SIP securing is 33,974 ms, whereas after the implementation of secure SIP, it increase to 39,964 ms. As for the jitter measurement, with or without secure-SIP, is approximately 0,6 ms. No packets are lost, so the value of packet loss is 0%. Throughput is about 50 packet/second

ABSTRACT
The advance rapid of information and communication technology also its potential of widespread utilization, open opportunities in accessing, managing, and exploiting the information in larga scale volume quickly and accurately. Towards agricultural sector, the utilization in information and communication technology (ICT) can help reduce poverty and increase food security. ICT as a toll can improve the efficiency, productivity, and sustainability of agriculture through the provision and information quickly and accurately. The amount of benefits that can be taken through ICT mentioned above can only be achieved if ICT is used appropriately. This study aims to describe the condition of the use of ICT among farmers that include the type of ICT devices owned by farmers, the information needed by farmers, and the factors that affect farmers in the use of ICT tools. This is a qualitative research and use thematic analysis technique for processing the data. The result of this research showed that the utilization of ICT among farmers, where the most common ICT devices owned by farmers are mobile phone and television. The most needed information among farmers is the price rate of agricultural commodities, and factors that most influence the use of ICT among farmers is lack of human resource capability in using ICT., The advance rapid of information and communication technology also its potential of widespread utilization, open opportunities in accessing, managing, and exploiting the information in larga scale volume quickly and accurately.

This book explains the philosophy of the polar encoding and decoding technique. Polar codes are one of the most recently discovered capacity-achieving channel codes. What sets them apart from other channel codes is the fact that polar codes are designed mathematically and their performance is mathematically proven. The book develops related fundamental concepts from information theory, such as entropy, mutual information, and channel capacity. It then explains the successive cancellation decoding logic and provides the necessary formulas, moving on to demonstrate the successive cancellation decoding operation with a tree structure. It also demonstrates the calculation of split channel capacities when polar codes are employed for binary erasure channels, and explains the mathematical formulation of successive cancellation decoding for polar codes. In closing, the book presents and proves the channel polarization theorem, before mathematically analyzing the performance of polar codes.
