Voice over Internet Protocol (VoIP) is a technology that is capable of passing voice traffic, in the form of packets through the network Internet Protocol (IP). IP network itself is a data communications network based packet-switch. The voice signal before experiencing bundled voice coding or format conversion of sound into digital form that can be passed over an IP network. Telephony, Internet telephony, or termed VoIP (Voice Over Internet Protocol.This communication system use VoIP (Voice over Internet Protocol), ie voice calls over data services (internet). This communication was developed using Android-based devices. Based on characteristics, android devices are open source, so users do not need to have a license to be able to have android-based devices. In addition, the android device that must be connected to a SIP (Session Iniation Protocol) is a data service that can be done with a paid subscription of the user of the operator using a conventional pulse. Telecommunications designed will use a hybrid system, the merger between VoIP communications with data communications GSM network. With basic calculations where Coding standards G 729, is a standard that can be used for voice communication system through data networks with rate of 8 Kbps. The implementation of the G729 codec is effect on communication systems VOIP.

Di dalam komunikasi Voice over Internet Protocol (VoIP) mengenal beberapa macam protocol tambahan selain protocol standar internet Transfer Control Protocol/Internet Protocol (TCP/IP), beberapa diantaranya adalah protocol Session Initation Protocol (SIP), Inter-Asterisk eXchange (IAX) dan H.323. Performansi perlu dijaga mengingat VoIP mempunyai kemungkinan melakukan berbagai cara kompresi untuk menciptakan efisiensi saluran dan pemilihan protocol yang tepat. Teknologi VoIP pada dasarnya tidak memiliki jaminan keamanan pada setiap komunikasi. Keamanan ketika melakukan komunikasi suara merupakan sesuatu yang sangat penting karena menyangkut privasi penggunanya. Penggunaan Virtual Private Network (VPN) merupakan salah satu solusi untuk menutup celah keamanan pada kasus di atas. Analisis yang dilakukan pada artikel ini adalah performa yang dihasilkan VoIP yang menggunakan protocol IAX dan SIP. Penelitian ini mengahasilkan kesimpulan bahwa performansi yang paling baik digunakan untuk membangun sistem komunikasi VoIP adalah protocol IAX dengan menggunakan sistem keamanan VPN Point to Point Protocol (PPTP) dikarenakan nilai Quality of Service (QoS)  lebih tinggi daripada protocol SIP dan juga terbukti lebih aman saat diterapkan sistem keamanan Virtual Private Network Point to Point Protocol (VPN PPTP).

Algebraic Forms

Problem-solving ability became a learned process as well as a goal that must be achieved in learned mathematics so it is important for students to have these abilities, especially in algebraic form material. But in fact, in the material of algebraic forms, the ability was still minimally mastered by students. Based on the results of the interview, it shows that the lack of ability was due to the questions given by the teacher only in the form of routine questions taken from LKS or textbooks that did not require the use of problem-solving skills but only require the used of procedural formulas. Therefore, it was necessary to develop test questions that contain question items that could measure students' problem-solving abilities in the algebraic form of material. This type of research was developed researched using the ADDIE model which stands for analysis, design, development, implementation, and evaluation. Data collection techniques used in this study were validation questionnaires and tests. Meanwhile, the data collection instruments were validation questionnaire sheets and test sheets. The test subjects in this study were class VII C students of MTs Salafiyah Syafi'iyah Seblak Jombang. The results showed that the product developed in the form of a test was declared valid by the expert with an average validity of 3.75 and was in very valid criteria. Meanwhile, the results of the empirical validity test showed that only four of the five items on the test developed were declared valid and of the four items that were valid, the reliability value of 0.786 with high criteria was obtained. The research findings prove that the developed test contains only four items that were valid both theoretically and empirically and reliably so that they could be used to measure students' problem-solving abilities on the algebraic form of material.

Voice Over Internet Protocol (VOIP) merupakan teknologi yang memanfaatkan Internet Protocol untuk menyediakan komunikasi voice secara elektronis dan real-time. Teknologi VOIP merupakan teknologi telekomunikasi masa kini, dimana biaya yang dikeluarkan untuk infrastruktur teknologi ini jauh lebih murah dibanding teknologi telekomunikasi yang umumnya digunakan masyarakat saat ini. Asterisk merupakan softswicth untuk mengoperasikan proxy, yang berbasis session initiation protocol (SIP). Sistem operasi Ubuntu 11.04 sebagai server VOIP cukup fleksibel untuk mendukung kinerja paket Asterisk. Tujuan dari penelitian ini adalah membangun server VOIP berbasis Asterisk, agar dapat dikembangkan pada penelitian selanjutnya sesuai dengan kebutuhan. Metodologi penelitian yang dilakukan, secara garis besar terdiri dari dua alur. Yaitu studi literatur dan percobaan. Penelitian ini dilakukan pada jaringan intranet atau Local Area Network (LAN). Sehingga VOIP disini difungsikan sebagai pemaksimalan jaringan intranet yang sudah ada tersebut untuk menekan biaya pengeluaran kebutuhan komunikasi. Layanan yang disediakan pada penelitian ini berbentuk voice dan video dengan layanan call client to client, video call, conference dan mailbox/voicemail. Kata Kunci: VOIP, SIP, Asterisk, IP-PBX, Telephony.

Voice over Internet Protocol (VoIP) merupakan teknologi komunikasi suara berbasis IP, dimana user dapat melakukan komunikasi suara hanya dengan menggunakan jaringan internet, intranet, atau ethernet. PT National Label merupakan perusahaan swasta yang terus berkembang, sehingga membutuhkan sarana komunikasi yang baik untuk menunjang produktifitas perusahaan. Saat ini PT National Label sudah menerapkan telepon PABX sebagai sarana komunikasi. Mahalnya harga telepon PABX dapat mengakibatkan meningkatnya biaya operasional perusahaan, sehingga dengan dirancang dan diimplentasikannya  VoIP dapat menjadi alternatif solusi dari permasalahan tersebut. Jaringan VoIP yang dirancang menggunakan server CentOS sehingga menjadi sistem Trixbox CE berbasis SIP (Session Initiation Protocol). Dengan menggunakan infrastruktur jaringan nirkabel seperti wifi, teknologi VoIP dapat digunakan pada telepon jaringan atau diperangkat mobile dengan menggunakan softphone seperti aplikasi mobile X-Lite dan Zoiper sebagai pengganti IP Phone yang terhubung dengan satu jaringan. Diharapkan dengan adanya teknologi VoIP di PT National Label dapat memberikan manfaat bagi karyawan dalam menunjang sarana komunikasi via internet tanpa mengeluarkan biaya yang besar. Kata Kunci: Jaringan, Internet, Server, VoIP.
